Continuously variable trans-
mission

The continuously variable transmission is
electronically controlled and provides an
infinite number of forward speeds and 1
reverse speed. It also has a manual mode.

WARNING

Do not shift from the “P” or “N”
position into the “D” or “R” position
while depressing the accelerator
pedal. This may cause the vehicle
to jump forward or backward.

CAUTION

Observe the following precau-

tions. Otherwise, the transmis-
sion could be damaged.

– Shift into the “P” or “R” posi-

tion only after the vehicle has
completely stopped.

– Do not shift from the “D”

position into the “R” position
or vice versa until the vehicle
has completely stopped.

Do not race the engine for more

than 5 seconds in any position
except the “N” or “P” position

when the brake is applied or
when chocks are used in the
wheels. This may cause the
transmission fluid to overheat.

Never move the vehicle as fol-

lows. Doing so may result in an
unexpected accident or malfunc-
tion.

– Moving rearward by inertia

with the select lever set in a
forward driving position.

– Moving forward by inertia with

the select lever set in the “R”
position.

When parking the vehicle, first

securely apply the parking brake
and then place the select lever in
the “P” position. Do not park for a
long time with the select lever in
any other position as doing so
could result in a dead battery.

NOTE

When the engine coolant tempera-

ture is still low, the transmission will
upshift to higher engine speeds than
when the coolant temperature is suffi-
ciently high in order to shorten the
warm-up time and improve driveability.
The gearshift timing will automatically

shift to the normal timing after the
engine has warmed up.
.

Immediately after transmission fluid

is replaced, you may feel that the
transmission operation is somewhat
unusual. This results from invalidation
of data which the on-board computer
has collected and stored in memory to
allow the transmission to shift at the
most appropriate times for the current
condition of your vehicle. Optimized
shifting will be restored as the vehicle
continues to be driven for a while.
.

When driving under continuous hea-

vy load conditions such as when climb-
ing a long, steep hill, the engine speed
or the vehicle speed may automatically
be reduced. This is not a malfunction.
This phenomenon results from the
engine control function maintaining
the cooling performance of the vehicle.
The engine and vehicle speed will
return to a normal speed when the
engine is able to maintain the optimum
cooling performance after the heavy
load decreases. Take extremely care
when driving under a heavy load.
.

The continuously variable transmis-

sion is a chain type system that pro-
vides superior transmission efficiency
for maximum fuel economy. At times,
depending on varying driving condi-
tions, a chain operating noise may be

heard that is characteristic of this type
of system.

Select lever

Select lever button

: With the brake pedal depressed, shift

while pressing the select lever button
in.

: Shift while pressing the select lever

button in.

: Shift without pressing the select lever

button.

The select lever has four positions, “P”,
“R”, “N”, “D” and it also has an “M” position
for using the manual mode.

NOTE

For some models, to protect the engine
while the select lever is in the “P” or “N”
position, the engine is controlled so
that the engine speed may not become
too high even if the accelerator pedal is
depressed hard.

P (Park)

This position is for parking the vehicle and
starting the engine. In this position, the
transmission is mechanically locked to
prevent the vehicle from rolling freely.

When you park the vehicle, first apply the
parking brake firmly, then shift into the “P”
position. Do not hold the vehicle with only
the mechanical friction of the transmission.

To shift the select lever from the “P”
position to any other position, you should
depress the brake pedal fully then move
the select lever. This prevents the vehicle
from lurching when it is started.

R (Reverse)

This position is for backing the vehicle. To
shift from the “N” to “R” position, stop the
vehicle completely then move the lever to
the “R” position while pressing the select
lever button in.

Even when you have turned the ignition
switch to the “LOCK”/“OFF” position, you
can still move the select lever from the “N”
to “R” position for a limited time period by
depressing the brake pedal, and then it
becomes impossible. For details, refer to
“Shift lock function” F7-27.

Starting and operating/Continuously variable transmission

7-24

(291,1)

北米Model "A1720BE-A" EDITED: 2018/ 3/ 9

N (Neutral)

This position is for restarting a stalled
engine. In this position, the transmission is
neutral, meaning that the wheels and
transmission are not locked. Therefore,
the vehicle will roll freely, even on the
slightest incline unless the parking brake
or foot brake is applied.

WARNING

Do not drive the vehicle with the
select lever in the “N” (neutral)
position. Engine braking has no
effect in this condition and the risk
of an accident is consequently in-
creased.

NOTE

If the select lever is in the “N” position
when you stop the engine for parking,
you may not subsequently be able to
move it to the “R” and “P” positions. If
this happens, turn the ignition switch to
the “ON” position. You will then be able
to move the select lever to the “P”
position.

D (Drive)

This position is for normal driving. The
transmission shifts automatically and con-
tinuously into a suitable gear according to
the vehicle speed and the acceleration you
require. Also, while driving up and down a
hill, the transmission assists and controls
the driving performance and engine brak-
ing while corresponding to the road grade.

When more acceleration is required in the
“D” position, depress the accelerator pedal
fully to the floor and hold that position. The
transmission will automatically downshift.
If the Intelligent (I) mode or the Sport (S)
mode has been selected, the transmission
will operate like a conventional automatic
transmission. When you release the pedal,
the transmission will return to the original
gear position.

If you operate one of the shift paddles
behind the steering wheel while driving in
the “D” position, the transmission will
temporarily switch to the manual mode.
In this mode, you can shift into any gear
position using the shift paddles. For details
about the manual mode, refer to “Selection
of manual mode” F7-25. Once the vehicle
speed stabilizes, the transmission will
switch from the manual mode back to the
“D” position for normal driving.

Selection of manual mode

With the vehicle either moving or station-
ary, move the select lever from the “D”
position to the “M” position to select the
manual mode.

Upshift indicator

Downshift indicator

Gear position indicator

When the manual mode is selected, the
gear position indicator and upshift indica-
tor and/or downshift indicator on the
combination meter appear.

The gear position indicator shows the
currently selected gear in the following
range.
.

1st-to-8th-gear range (when the Sport

Sharp (S#) mode is selected)
.

1st-to-6th-gear range (in other situa-

tions)

The upshift and downshift indicators show
when a gear shift is possible. When the
upshift indicator “

” appears, upshifting is

possible. When the downshift indicator

“

” appears, downshifting is possible.

When both indicators appear, upshifting
and downshifting are both possible. When
the vehicle stops (for example, at traffic
signals), the downshift indicator turns off.

Gearshifts can be performed using the
shift paddle behind the steering wheel.

To upshift to the next higher gear position,
pull the shift paddle that has “+” indicated
on it. To downshift to the next lower gear
position, pull the shift paddle that has “–”
indicated on it.

CAUTION

Do not place or hang anything on the
shift paddles. Doing so may result in
accidental gear shifting.

NOTE

Please read the following points care-
fully and bear them in mind when using
the manual mode.
.

If you attempt to shift down when the

engine speed is too high, i.e., when a
downshift would push the tachometer
needle beyond the red zone, beeps will
be emitted to warn you that the down-
shift is not possible.
.

If you attempt to shift up when the

vehicle speed is too low, the transmis-
sion will not respond.
.

You can perform a skip-shift (for

example, from 4th to 2nd) by operating
the shift paddle twice in rapid succes-
sion.
.

The transmission automatically se-

lects 1st gear when the vehicle stops
moving.
.

If the temperature of the transmis-

sion fluid becomes too high, the “AT
OIL TEMP” warning light on the combi-
nation meter will illuminate. Immedi-
ately stop the vehicle in a safe location
and let the engine idle until the warning
light turns off.
.

By selecting the Sport Sharp (S#)

mode, upshifting will not occur auto-
matically. According to the road condi-
tions, shift change manually so that the
tachometer needle does not enter the

red zone. Also, if the engine revolutions
reach the specified number, the fuel
supply will be cut. In this case, perform
shift up operation.

To deselect the manual mode

To deselect the manual mode, return the
select lever to the “D” position from the “M”
position.

Shift lock function

The shift lock function helps prevent the
improper operation of the select lever.
.

You cannot move the select lever with

the ignition switch in the “ON” position and
the brake pedal depressed.
.

You cannot move the select lever from

the “P” position to any other position
unless the brake pedal is depressed.
Depress the brake pedal first, and then
operate the select lever.
.

Only the “P” position allows you to turn

the ignition switch from the “ACC” position
to the “LOCK”/“OFF” position and remove
the key from the ignition switch.
.

If you turn the ignition switch to the

“LOCK”/“OFF” position while the select
lever is in the “N” position, the select lever
may not be moved to the “P” position after
a period of time. Therefore, move the
select lever to the “P” position with the
brake pedal depressed soon after turning

the ignition switch to the “LOCK”/“OFF”
position.

Shift lock release

If you cannot move the select lever, turn
the ignition switch back to the “ON”
position then move the select lever to the
“P” position with the select lever button
pressed and brake pedal depressed.

If the select lever does not move after
performing the above procedure, perform
the following steps.
.

When you cannot shift the select

lever from “P” to “N”:
Refer to “Shift lock release using the shift
lock release button” F7-27.
.

When you cannot shift the select

lever from “N” to “R”, “P”:
Within 60 seconds after placing the ignition
switch in the “ACC” position, move the
select lever to the “P” position with the
select lever button pressed and brake
pedal depressed.

If you must perform the above procedure,
the shift lock system (or the vehicle control
system) may be malfunctioning. Contact a
SUBARU dealer for an inspection as soon
as possible.

If the select lever does not move after
performing the above procedure, refer to

“Shift lock release using the shift lock
release button” F7-27.

Shift lock release using the shift
lock release button

Perform the following procedure to release
the shift lock.
1. Apply the parking brake and stop the
engine.

2. Wrap the tip of a flat-head screwdriver
with vinyl tape or a cloth and use it to
remove the shift lock cover. The shift lock
release button is located under the shift
lock cover.

Driving tips

NOTE

If the accelerator and brake pedals are
depressed at the same time, driving
torque may be restrained. This is not a
malfunction.

Always apply the foot or parking brake

when the vehicle is stopped in the “D” or
“R” position.
.

Make sure to apply the parking brake

when parking your vehicle. Do not hold the
vehicle with only the mechanical friction of
the transmission.
.

Do not keep the vehicle in a stationary

position on an uphill grade by using the “D”
position. Use the brake instead.
.

The engine may, on rare occasions,

knock when the vehicle rapidly acceler-
ates or rapidly pulls away from a standstill.
This phenomenon does not indicate a
malfunction.

SI-DRIVE (if equipped)

SI-DRIVE (SUBARU Intelligent Drive)
works to maximize engine performance,
control and efficiency.
This system consists of three modes:
.

Intelligent (I) mode

Sport (S) mode

Sport Sharp (S#) mode

By adjusting the SI-DRIVE selector, the
character of the power unit changes.

Intelligent (I) mode

For smooth, efficient performance
driving

The Intelligent (I) mode provides well-
balanced performance with greater fuel

efficiency and smooth driveability without
stress. Power delivery is moderate during
acceleration for maximum fuel efficiency.
This is ideal for around-town driving and
situations that do not require full power
output. It provides better control in difficult
driving conditions, such as slippery roads
or loose surfaces, due to gentler throttle
response.

STI:

When the Intelligent (I) mode is selected, a
shift-up indicator “

” on the combination

meter will blink to signal the best time to
shift gears for maximum fuel efficiency.

Except STI:
The linear acceleration characteristic of
the Intelligent (I) mode is ideal for normal
driving.

Sport (S) mode

For all-around performance driving

The Sport (S) mode provides the engine
power desired by those who want to make
the driving experience their own personal
adventure.

STI:
The linear acceleration characteristic of
the Sport (S) mode is ideal for normal
driving.

Sport Sharp (S#) mode

For maximum performance driving

For sports-minded drivers, the Sport
Sharp (S#) mode offers an exhilarating
level of engine performance and control.
The throttle becomes more responsive
regardless of the engine speed. Delivering
maximum driving enjoyment, this mode is
ideal for driving on twisting roads and for
merging or overtaking other vehicles on
the freeway with confidence.

When you select the Sport Sharp (S#)
mode with the select lever in the “D”
position, the transmission gear ratio will
shift from variable speed to eight-speed.
The select lever/gear position indicator
display will change from “D” to the gear
position.

When selecting Sport Sharp (S#) mode,
the following controls will be applied.

Uphill control

Prevents unnecessary shift-up/shift-down
during ascent.
.

Cornering control

While turning, if there is a large centrifugal
force, shift-up will not occur: during re-
acceleration.
.

Braking control

At the beginning of corners etc., heavy
application of the brake pedal will cause
automatic downshift and gently re-accel-
erate.
.

Sudden acceleration return control

During acceleration, if acceleration pedal
is returned suddenly (for example, at
corners etc.), shift-up will not be applied.

SI-DRIVE switch

NOTE

The next time you turn on the engine,

the following SI-DRIVE mode will be
selected.

– Intelligent (I) mode if you have
turned off the engine in the Intelli-
gent (I) mode
– Sport (S) mode if you have turned
off the engine in the Sport (S) mode
or Sport Sharp (S#) mode

If the CHECK ENGINE warning light/

malfunction indicator light illuminates
during engine operation, the SI-DRIVE
mode changes to the Sport (S) mode. In
this case, it is not possible to change to
the Sport Sharp (S#) mode or Intelligent
(I) mode.
.

If the engine coolant temperature

becomes so high that the engine could
overheat, it is not possible to change to
the Sport Sharp (S#) mode. While the
vehicle is in the Sport Sharp (S#) mode,
it changes to the Sport (S) mode when
the engine coolant temperature in-
creases.

Limited slip differential (LSD)
(STI)

The LSD provides optimum distribution of
power according to the difference in
revolutions between the right and left
wheels that may be caused by certain
driving conditions, thereby improving driv-
ing stability on snow-covered, muddy or
other slippery roads or when high speed
driving.

CAUTION

Never start the engine while a tire

on one side is jacked up, as the
vehicle may move.

If one tire is spinning in mud,

avoid continued spinning at high
speed as this could adversely
affect the LSD.

If you use a temporary spare tire

to replace a flat tire, be sure to
use the original temporary spare
tire stored in the vehicle. Using
other sizes will adversely affect
the LSD.

Power steering

STI

The vehicle is equipped with a hydraulic
power steering system. The power steer-
ing system operates only when the engine
is running.
If you lose power steering assist because
the engine stops or the system fails to
function, you can steer but it will take much
more effort.

CAUTION

Do not hold the steering wheel at the
fully locked position left or right for
more than 5 seconds. This may
damage the power steering pump.

NOTE

Right after the engine has been started
and before it has warmed up, you may
hear a noise coming from areas adja-
cent to the power steering pump which
is located at the right-front area of the
engine compartment. This noise is
normal. It does not indicate power
steering system trouble.

Power steering warning light

The vehicle is equipped with an electric
power steering system. The power steer-
ing system operates only while the engine
is running. When you turn the ignition
switch to the “ON” position, the power
steering warning light on the combination
meter illuminates to inform the driver that
the warning system is functioning properly.
Then, if the engine started, the warning
light turns off to inform the driver that the
steering power assist is operational.

CAUTION

While the power steering warning
light is illuminated, there may be
more resistance when the steering
wheel is operated. Drive carefully to
the nearest SUBARU dealer and
have the vehicle inspected immedi-
ately.

NOTE

If you operate the steering wheel in the
following ways, the power steering
control system may temporarily limit
the power assist in order to prevent the
system components, such as the con-
trol computer and drive motor, from
overheating.
.

You operate the steering wheel fre-

quently and turn it sharply while the
vehicle is maneuvered at extremely low
speeds, such as while frequently turn-
ing the steering wheel during parallel
parking.
.

You keep the steering wheel in the

fully turned position for a long period of
time.

At this time, there will be more resis-
tance when steering. However this is
not a malfunction. Normal steering
force will be restored after the steering

wheel is not operated for a while and
the power steering control system has
an opportunity to cool down. However,
if the power steering is operated in a
non-standard way which causes power
assist limitation to occur too frequently,
this may result in a malfunction of the
power steering control system.

Braking

Braking tips

WARNING

Never rest your foot on the brake
pedal while driving. This can cause
dangerous overheating of the
brakes and needless wear on the
brake pads and linings.

When the brakes get wet

When driving in rain or after washing the
vehicle, the brakes may get wet. As a
result, brake stopping distance will be
longer. To dry the brakes, drive the vehicle
at a safe speed while lightly depressing the
brake pedal to heat up the brakes.

Use of engine braking

Remember to make use of engine braking
in addition to foot braking. When descend-
ing a grade, if only the foot brake is used,
the brakes may start working improperly
because of brake fluid overheating,
caused by overheated brake pads. To help
prevent this, shift into a lower gear to get
stronger engine braking.

Braking when a tire is punctured

Do not depress the brake pedal suddenly
when a tire is punctured. This could cause

a loss of control of the vehicle. Keep
driving straight ahead while gradually
reducing speed. Then slowly pull off the
road to a safe place.

Brake system

Two separate circuits

Your vehicle has two separate circuit brake
systems. Each circuit works diagonally
across the vehicle. If one circuit of the
brake system should fail, the other half of
the system still works. If one circuit fails,
the brake pedal will go down much closer
to the floor than usual and you will need to
press it down much harder. And a much
longer distance will be needed to stop the
vehicle.

Brake booster

The brake booster uses engine manifold
vacuum to assist braking force. Do not turn
off the engine while driving because that
will turn off the brake booster, resulting in
poor braking power.
The brakes will continue to work even
when the brake booster completely stops
functioning. If this happens, however, you
will have to depress the pedal much harder
than normal and the braking distance will
increase.

Brake assist system

WARNING

Do not be overconfident about the
brake assist. It is not a system that
brings more braking ability to the
vehicle beyond its braking capabil-
ity. Always use the utmost care
when driving regarding vehicle
speed and safe distance.

CAUTION

When you need to brake suddenly,
continue depressing the brake pedal
strongly to obtain the effect of the
brake assist.

Brake assist is a driver assistance system.
It assists the brake power when the driver
cannot depress the brake pedal strongly
and the brake power is insufficient.
Brake assist generates the brake power
according to the speed at which the driver
depresses the brake pedal.

北米Model "A1720BE-A" EDITED: 2018/ 3/ 9

NOTE

When you depress the brake pedal
strongly or suddenly, the following
phenomena occur. However, even
though these occur, they do not indi-
cate any malfunctions, and the brake
assist system is operating properly.
.

You might feel that the brake pedal is

applied by lighter force and generates a
greater braking force.
.

You might hear an ABS operating

noise from the engine compartment.

Disc brake pad wear warning
indicators

The disc brake pad wear warning indica-
tors on the disc brakes give a warning
noise when the brake pads are worn.

If a squeaking or scraping noise is heard
from the disc brakes while braking, im-
mediately have your vehicle checked by
your SUBARU dealer.

High performance brake sys-
tem (STI)

Your vehicle is equipped with large, high
performance brake pads that provide
optimum braking force under various driv-
ing conditions. The brake pads have the
following characteristics.

Brake noises
The brake pads are made of iron-based
material. Therefore, unusual noise may be
heard when depressing the brake pedal
slightly before stopping completely. How-
ever, this does not indicate a malfunction.

Discoloration
Frequent severe driving, such as repeated
driving on sharp uphill or downhill grades,
can cause discoloration of the paint on the
brake calipers. The discoloration will not
affect the braking performance.

Stuck brake pads
.

If the vehicle is left parked for an

extended period of time with the brake
system wet, the iron in the brake pads may
form rust and cause the brake pads and
disc rotors to stick together. This may

result in noise or vibration while driving. If
this occurs, fully depress the brake pedal
several times to free the brake pads.
.

If the vehicle is left parked for an

extended period of time in a cold tempera-
ture, the brake pads and disc rotors may
be frozen and stuck together. In this case,
it may be difficult to start the vehicle.

Brake dust
Due to the material used for the brake
pads, the wheels may become covered in
brake dust. This is not a malfunction, and
will not affect the brake performance.

pad (if equipped)

Brake dust
Due to the material used for the brake

ABS (Anti-lock Brake Sys-
tem)

The ABS prevents the lock-up of wheels
which may occur during sudden braking or
braking on slippery road surfaces. This
helps prevent the loss of steering control
and directional stability caused by wheel
lock-up.

When the ABS is operating, you may hear
a chattering noise or feel a slight vibration
in the brake pedal. This is normal when the
ABS operates.

The ABS will not operate when the vehicle
speed is below approximately 6 mph (10
km/h).

WARNING

Always use the utmost care in driv-
ing – overconfidence because you
are driving a vehicle with the ABS
could easily lead to a serious acci-
dent.

CAUTION

The ABS does not always de-

crease stopping distance. You
should always maintain a safe
following distance from other
vehicles.

When driving on badly surfaced

roads, gravel roads, icy roads, or
over deep newly fallen snow,
stopping distances may be long-
er for a vehicle with the ABS than
one without. When driving under
these conditions, therefore, re-
duce your speed and leave ample
distance from other vehicles.

When you feel the ABS operating,

you should maintain constant
brake pedal pressure. Do not
pump the brake pedal since
doing so may defeat the opera-
tion of the ABS system.

ABS self-check

Just after the vehicle is started, you may
feel on the brake pedal a vibration similar
to when the ABS operates, and you may
also hear the sound of the ABS working
from the engine compartment. This is
caused by an automatic functional test of
the ABS being carried out and does not
indicate any abnormal condition.

Electronic Brake Force Dis-
tribution (EBD) system

The EBD system maximizes the effective-
ness of the brakes by allowing the rear
brakes to supply a greater proportion of the
braking force. It functions by adjusting the
distribution of braking force to the rear
wheels in accordance with the vehicle’s
loading condition and speed.
The EBD system is an integral part of the
ABS and uses some of the ABS compo-
nents to perform its function of optimizing
the distribution of braking force. If any of
the ABS components used by the EBD
system malfunction, the EBD system also
stops working.

When the EBD system is operating, you
may hear a chattering noise or feel a slight
vibration in the brake pedal. This is normal
and does not indicate a malfunction.

Steps to take if EBD system
malfunctions

Brake and ABS warning light

If a malfunction occurs in the EBD system,
the system stops working and the brake
system warning light and ABS warning
light illuminate simultaneously.

The EBD system may be malfunctioning if
the brake system warning light and ABS
warning light illuminate simultaneously
while driving.
Even if the EBD system malfunctions, the
conventional braking system will still func-
tion. However, the rear wheels will be more
prone to locking when the brakes are
applied harder than usual and the vehicle’s
motion may therefore become somewhat
harder to control.

If the brake system warning light and ABS
warning light illuminate simultaneously,
take the following steps.
1. Stop the vehicle in the nearest safe, flat
location.
2. Apply the parking brake and turn off the
engine.
3. Restart the engine.
4. Release the parking brake.

Even if both warning lights turn off:
The EBD system may be malfunctioning.
Drive carefully to the nearest SUBARU
dealer and have the system inspected.

If both warning lights illuminate again
and remain illuminated after restarting
the engine:
1. Turn off the engine again.
2. Apply the parking brake.
3. Check the brake fluid level. For details
about checking the brake fluid level, refer
to “Checking the fluid level” F11-23.

If the brake fluid level is not below the

“MIN” mark, the EBD system may be
malfunctioning. Drive carefully to the
nearest SUBARU dealer and have the
system inspected.
.

If the brake fluid level is below the “MIN”

mark, DO NOT drive the vehicle. Instead,
have the vehicle towed to the nearest

WARNING

Driving with the brake system

warning light illuminated is dan-
gerous. This indicates your brake
system may not be working prop-
erly. If the light remains illumi-
nated, have the brakes inspected
by a SUBARU dealer immedi-
ately.

If at all in doubt about whether the

brakes are operating properly, do
not drive the vehicle. Have your
vehicle towed to the nearest
SUBARU dealer for repair.

Vehicle Dynamics Control
system

WARNING

Always use the utmost care in driv-
ing – overconfidence because you
are driving a vehicle with the Vehicle
Dynamics Control system could ea-
sily lead to a serious accident.

CAUTION

Even if your vehicle is equipped

with Vehicle Dynamics Control
system, winter tires should be
used when driving on snow-cov-
ered or icy roads; in addition,
vehicle speed should be reduced
considerably. Simply having a
Vehicle Dynamics Control sys-
tem does not guarantee that the
vehicle will be able to avoid
accidents in any situation.

Activation of the Vehicle Dy-

namics Control system is an
indication that the road being
travelled on has a slippery sur-
face; since having Vehicle Dy-
namics Control is no guarantee

that full vehicle control will be
maintained at all times and under
all conditions, its activation
should be seen as a sign that
the speed of the vehicle should
be reduced considerably.

Whenever suspension compo-

nents, steering components, or
an axle are removed from a
vehicle, have an inspection of
that system performed by an
authorized SUBARU dealer.

Observe the following precau-

tions in order to ensure that the
Vehicle Dynamics Control sys-
tem is operating properly:

– Fit all four wheels with tires of

the same size, type, and
b r a n d . F u r t h e r m o r e , t h e
amount of wear should be the
same for all four tires.

– Keep the tire pressure at the

proper level as shown on the
vehicle placard attached to
the driver’s side door pillar.

– When replacing a flat tire, use

only the specified temporary
spare tire. However, even with
the specified temporary spare
tire, the effectiveness of the

system will be reduced.

If you use non-matching tires, the

Vehicle Dynamics Control sys-
tem may not operate correctly.

The Vehicle Dynamics Control

system helps prevent unstable
vehicle motion such as skidding
using control of the brakes and
engine power. Do not turn off the
Vehicle Dynamics Control sys-
tem unless it is absolutely neces-
sary. If you must turn off the
Vehicle Dynamics Control sys-
tem, drive very carefully accord-
ing to the road surface condition.

In the event of wheelspin and/or skidding
on a slippery road surface and/or during
cornering and/or an evasive maneuver,
the Vehicle Dynamics Control system
adjusts the engine’s output and the
wheels’ respective braking forces to help
maintain traction and directional control.

Traction Control Function

The traction control function is designed to
prevent spinning of the driving wheels on
slippery road surfaces, thereby helping to
maintain traction and directional control.
Activation of this function is shown by
flashing the Vehicle Dynamics Control
operation indicator light.

Skid Suppression Function

The skid suppression function is designed
to help maintain directional stability by
suppressing the wheels’ tendency to slide
sideways during steering operations. Acti-
vation of this function is shown by flashing
of the Vehicle Dynamics Control operation
indicator light.

Vehicle Dynamics Control operation indi-
cator light

NOTE

The Vehicle Dynamics Control sys-

tem may be considered normal when
the following conditions occur.

– Slight twitching of the brake
pedal is felt.
– The vehicle or steering wheel
shakes to a small degree.

– An operating sound from the
engine compartment is heard briefly
when starting the engine and when
driving off after starting the engine.
– The brake pedal seems to jolt
when driving off after starting the
engine.

In the circumstances shown in the

following list, the vehicle may be less
stable than it feels to the driver. The
Vehicle Dynamics Control System may
therefore operate. Such operation does
not indicate a system malfunction.

– on gravel-covered or rutted roads
– on unfinished roads
– when the vehicle is fitted with
snow tires or winter tires

Activation of the Vehicle Dynamics

Control system will cause operation of
the steering wheel to feel slightly
different compared to that for normal
conditions.
.

It is always important to reduce

speed when approaching a corner,
even if your vehicle is equipped with
the Vehicle Dynamics Control system.
.

Always turn off the engine before

replacing a tire. Failure to do so may
render the Vehicle Dynamics Control
system unable to operate correctly.
