ence from another radar source, making it
impossible to detect a vehicle ahead, the
AEB system is automatically turned off.

The AEB system warning light (orange) will
illuminate.

Action to take

When the above conditions no longer exist,
the AEB system will resume automatically.

Condition B

When the sensor area of the front bumper
is covered with dirt or is obstructed, mak-
ing it impossible to detect a vehicle ahead,
the AEB system is automatically turned off.

The AEB system warning light (orange) will
illuminate and the “Unavailable: Front Ra-
dar Obstruction” warning message will ap-
pear in the vehicle information display.

When driving on roads with limited road
structures or buildings (for example, long
bridges, deserts, snow fields, driving next to
long walls), the system may illuminate the

AEB system warning light (orange) and dis-
play the “Unavailable: Front Radar Obstruc-
tion” message.

∙ Do not accelerate at full throttle in any

gear.

∙ Avoid quick starts.

∙ Avoid hard braking as much as pos-

sible.

BREAK-IN SCHEDULE

5-68

Starting and driving

Follow these easy-to-use Fuel Efficient
Driving Tips to help you achieve the most
fuel economy from your vehicle.

1. Use Smooth Accelerator and Brake

Pedal Application

∙ Avoid rapid starts and stops

∙ Use smooth, gentle accelerator and

brake application whenever possible

∙ Maintain constant speed while com-

muting and coast whenever possible

2. Maintain Constant Speed

∙ Look ahead to try and anticipate and

minimize stops

∙ Synchronizing your speed with traffic

lights allows you to reduce your num-
ber of stops

∙ Maintaining a steady speed can mini-

mize red light stops and improve fuel
efficiency

3. Use Air Conditioning (A/C) at Higher

Vehicle Speeds

∙ Below 40 mph (64 km/h), it is more

efficient to open windows to cool the
vehicle due to reduced engine load

∙ Above 40 mph (64 km/h), it is more

efficient to use A/C to cool the vehicle
due to increased aerodynamic drag

∙ Recirculating the cool air in the cabin

when the A/C is on reduces cooling
load

4. Drive at Economical Speeds and Dis-

tances

∙ Observing the speed limit and not

exceeding 60 mph (97 km/h) (where
legally allowed) can improve fuel effi-
ciency due to reduced aerodynamic
drag

∙ Maintaining a safe following distance

behind other vehicles reduces un-
necessary braking

∙ Safely monitoring traffic to anticipate

changes in speed permits reduced
braking and smooth acceleration
changes

∙ Select a gear range suitable to road

conditions

5. Use Cruise Control

∙ Using cruise control during highway

driving helps maintain a steady
speed

∙ Cruise control is particularly effective

in providing fuel savings when driving
on flat terrains

6. Plan for the Shortest Route

∙ Utilize a map or navigation system to

determine the best route to save
time

7. Avoid Idling

∙ Shutting off your engine when safe

for stops exceeding 30–60 seconds
saves fuel and reduces emissions

8. Buy an Automated Pass for Toll

Roads

∙ Automated passes permit drivers to

use special lanes to maintain cruis-
ing speed through the toll and avoid
stopping and starting

9. Winter Warm Up

∙ Limit idling time to minimize impact

to fuel economy

∙ Vehicles typically need no more than

30 seconds of idling at start-up to
effectively circulate the engine oil be-
fore driving

FUEL EFFICIENT DRIVING TIPS

Starting and driving

5-69

∙ Your vehicle will reach its ideal oper-

ating

temperature

quickly

while driving versus idling

10. Keeping your Vehicle Cool

∙ Park your vehicle in a covered parking

area or in the shade whenever pos-
sible

∙ When entering a hot vehicle, opening

the windows will help to reduce the
inside temperature faster, resulting in
reduced demand on your A/C sys-
tem

11. ECO Mode

∙ The ECO mode helps to enhance the

fuel economy by controlling the en-
gine

and

Continuously

Variable

Transmission (if so equipped) opera-
tion automatically to avoid rapid ac-
celeration.

∙ Keep your engine tuned up.

∙ Follow the recommended scheduled

maintenance.

∙ Keep the tires inflated to the correct

pressure. Low tire pressure increases
tire wear and lowers fuel economy.

∙ Keep the wheels in correct alignment.

Improper alignment increases tire wear
and lowers fuel economy.

∙ Use the recommended viscosity engine

oil. For additional information, refer to
“Engine oil and oil filter recommenda-
tions” in the “Technical and consumer
information” section of this manual.

INCREASING FUEL ECONOMY

5-70

Starting and driving

WARNING

∙ Do not stop or park the vehicle over

flammable materials such as dry
grass, waste paper or rags. They may
ignite and cause a fire.

∙ Safe parking procedures require that

both the parking brake be set and the
transmission placed in P (Park) for
Continuously Variable Transmission
(CVT) models or in an appropriate
gear for manual transmission (M/T)
models. Failure to do so could cause
the vehicle to move unexpectedly or
roll away and result in an accident.
Make sure the shift lever has been
pushed as far forward as it can go and
cannot be moved without depressing
the foot brake pedal.

∙ Never leave the engine running while

the vehicle is unattended.

∙ To help avoid risk of injury or death

through unintended operation of the
vehicle and/or its systems, do not
leave children, people who require the
assistance of others or pets unat-
tended in your vehicle. Additionally,
the temperature inside a closed ve-
hicle on a warm day can quickly be-
come high enough to cause a signifi-
cant risk of injury or death to people
and pets.

1. Firmly apply the parking brake.

2. M/T models

Place the shift lever in the R (Reverse)
position. When parking on an uphill
grade, place the shift lever in 1st gear.

CVT models

Move the shift lever into the P (Park)
position.

3. To help prevent the vehicle from rolling

into traffic when parked on an incline, it
is a good practice to turn the wheels as
illustrated.

Turn the wheels away from the curb
and move the vehicle back until the
curb side wheel gently touches the
curb.

∙ HEADED UPHILL OR DOWNHILL, NO

CURB

䊊

Turn the wheels toward the side of the
road so the vehicle will move away
from the center of the road if it moves.

4. Place the ignition switch in the LOCK

position and remove the key.

WARNING

∙ If the engine is not running or is

turned off while driving, the power as-
sist for the steering will not work.
Steering will be harder to operate.

∙ When the power steering warning

light illuminates with the engine run-
ning, there will be no power assist for
the steering. You will still have control
of the vehicle, but the steering will be
harder to operate. Have the power
steering system checked. It is recom-
mended that you visit a NISSAN dealer
for this service.

The power steering system is designed to
provide power assist while driving to oper-
ate the steering wheel with light force.

When the steering wheel is operated re-
peatedly or continuously while parking or
driving at a very low speed, the power as-
sist for the steering wheel will be reduced.
This is to prevent overheating of the power
steering system and protect it from getting
damaged. While the power assist is re-
duced, steering wheel operation will be-
come heavy. When the temperature of the
power steering system goes down, the
power assist level will return to normal.
Avoid repeating such steering wheel op-

erations that could cause the power steer-
ing system to overheat.

You may hear a noise when the steering
wheel is operated quickly. However, this is
not a malfunction.

If the power steering warning light illumi-
nates while the engine is running, it may
indicate the power steering system is not
functioning properly and may need servic-
ing. Have the power steering system
checked. It is recommended that you visit a
NISSAN dealer for this service.

When the power steering warning light illu-
minates with the engine running, there will
be no power assist for the steering, but you
will still have control of the vehicle. At this
time, greater steering effort is required to
operate the steering wheel, especially in
sharp turns and at low speeds.

For additional information, refer to “Power
steering warning light” in the “Instruments
and controls” section of this manual.

POWER STEERING

5-72

Starting and driving

The brake system has two separate hy-
draulic circuits. If one circuit malfunctions,
you will still have braking at two wheels.

BRAKE PRECAUTIONS

Vacuum assisted brakes

The brake booster aids braking by using
engine vacuum. If the engine stops, you
can stop the vehicle by depressing the
brake pedal. However, greater foot pres-
sure on the brake pedal will be required to
stop the vehicle and stopping distance will
be longer.

Using the brakes

Avoid resting your foot on the brake pedal
while driving. This will overheat the brakes,
wear out the brake pads faster, and reduce
gas mileage.

To help reduce brake wear and to prevent
the brakes from overheating, reduce speed
and downshift to a lower gear before going
down a slope or long grade. Overheated
brakes may reduce braking performance
and could result in loss of vehicle control.

WARNING

∙ While driving on a slippery surface, be

careful when braking, accelerating or
downshifting. Abrupt braking or ac-
celerating could cause the wheels to
skid and result in an accident.

∙ If the engine is not running or is

turned off while driving, the power as-
sist for the brakes will not work. Brak-
ing will be harder.

Wet brakes

When the vehicle is washed or driven
through water, the brakes may get wet. As
a result, your braking distance will be lon-
ger and the vehicle may pull to one side
during braking.

To dry the brakes, drive the vehicle at a safe
speed while lightly pressing the brake
pedal to heat up the brakes. Do this until
the brakes return to normal. Avoid driving
the vehicle at high speeds until the brakes
function correctly.

Parking brake break-in

Break in the parking brake shoes whenever
the stopping effect of the parking brake is
weakened or whenever the parking brake

shoes and/or drums/rotors are replaced,
in order to assure the best braking perfor-
mance.

This procedure is described in the vehicle
service manual. It is recommended that
you visit a NISSAN dealer for this service.

ANTI-LOCK BRAKING SYSTEM (ABS)

WARNING

∙ The ABS is a sophisticated device, but

it cannot prevent accidents resulting
from careless or dangerous driving
techniques. It can help maintain ve-
hicle control during braking on slip-
pery surfaces. Remember that stop-
ping distances on slippery surfaces
will be longer than on normal sur-
faces even with ABS. Stopping dis-
tances may also be longer on rough,
gravel or snow covered roads, or if you
are using tire chains. Always maintain
a safe distance from the vehicle in
front of you. Ultimately, the driver is
responsible for safety.

∙ Tire type and condition may also af-

fect braking effectiveness.

BRAKE SYSTEM

Starting and driving

5-73

– When replacing tires, install the

specified size of tires on all four
wheels.

– When installing a spare tire, make

sure that it is the proper size and
type as specified on the Tire and
Loading Information label. For ad-
ditional information, refer to “Tire
and Loading Information label” in
the “Technical and consumer infor-
mation” section of this manual.

– For additional information, refer to

“Wheels and tires” in the “Do-it-
yourself ” section of this manual.

The ABS controls the brakes so the wheels
do not lock during hard braking or when
braking on slippery surfaces. The system
detects the rotation speed at each wheel
and varies the brake fluid pressure to pre-
vent each wheel from locking and sliding.
By preventing each wheel from locking, the
system helps the driver maintain steering
control and helps to minimize swerving
and spinning on slippery surfaces.

Using the system

Depress the brake pedal and hold it down.
Depress the brake pedal with firm steady
pressure, but do not pump the brakes. The

Anti-lock Braking System will operate to
prevent the wheels from locking up. Steer
the vehicle to avoid obstacles.

WARNING

Do not pump the brake pedal. Doing so
may

result

increased

stopping

distances.

Self-test feature

The Anti-lock Braking System (ABS) in-
cludes electronic sensors, electric pumps,
hydraulic solenoids and a computer. The
computer has a built-in diagnostic feature
that tests the system each time you start
the engine and move the vehicle at a low
speed in forward or reverse. When the self-
test occurs, you may hear a “clunk” noise
and/or feel a pulsation in the brake pedal.
This is normal and does not indicate a mal-
function. If the computer senses a mal-
function, it switches the ABS off and illumi-
nates the ABS warning light on the
instrument panel. The brake system then
operates normally, but without anti-lock
assistance.

If the ABS warning light illuminates during
the self-test or while driving, have the ve-
hicle checked. It is recommended that you
visit a NISSAN dealer for this service.

Normal operation

The Anti-lock Braking System (ABS) oper-
ates at speeds above 3 - 6 mph (5 -
10 km/h). The speed varies according to
road conditions.

When the ABS senses that one or more
wheels are close to locking up, the actuator
rapidly applies and releases hydraulic pres-
sure. This action is similar to pumping the
brakes very quickly. You may feel a pulsa-
tion in the brake pedal and hear a noise
from under the hood or feel a vibration
from the actuator when it is operating. This
is normal and indicates that the ABS is op-
erating properly. However, the pulsation
may indicate that road conditions are haz-
ardous and extra care is required while
driving.

BRAKE ASSIST

When the force applied to the brake pedal
exceeds a certain level, the Brake Assist is
activated generating greater braking force
than a conventional brake booster even
with light pedal force.

5-74

Starting and driving

WARNING

The Brake Assist is only an aid to assist
braking operation and is not a collision
warning or avoidance device. It is the
driver’s responsibility to stay alert, drive
safely and be in control of the vehicle at
all times.

The VDC system uses various sensors to
monitor driver inputs and vehicle motion.
Under certain driving conditions, the VDC
system helps to perform the following
functions:

∙ Controls brake pressure to reduce

wheel slip on one slipping drive wheel
so power is transferred to a non-
slipping drive wheel on the same axle.

∙ Controls brake pressure and engine

output to reduce drive wheel slip based
on vehicle speed (traction control func-
tion).

∙ Controls brake pressure at individual

wheels and engine output to help the
driver maintain control of the vehicle in
the following conditions:

– Understeer (vehicle tends to not fol-

low the steered path despite in-
creased steering input)

– Oversteer (vehicle tends to spin due

to certain road or driving conditions)

The VDC system can help the driver to
maintain control of the vehicle, but it can-
not prevent loss of vehicle control in all driv-
ing situations.

When the VDC system operates, the
indicator light in the instrument panel
flashes to note the following:

∙ The road may be slippery or the system

may determine some action is required
to help keep the vehicle on the steered
path.

∙ You may feel a pulsation in the brake

pedal and hear a noise or vibration from
under the hood. This is normal and indi-
cates that the VDC system is working
properly.

∙ Adjust your speed and driving to the

road conditions.

For additional information, refer to “Slip in-
dicator light” and ”Vehicle Dynamic Control
(VDC) OFF indicator light” in the ”Instru-
ments and controls” section of this manual.

If a malfunction occurs in the system,
the

indicator light comes on in the

instrument panel. The VDC system auto-
matically turns off when the indicator light
is off.
The VDC OFF switch is used to turn off the
VDC system. The

indicator light and

the AEB system warning light illuminates to
indicate the VDC system is off.

VEHICLE DYNAMIC CONTROL (VDC)
SYSTEM

Starting and driving

5-75

When the VDC OFF switch is used to turn off
the system, the VDC system still operates
to prevent one drive wheel from slipping by
transferring power to a non-slipping drive
wheel. The

indicator light flashes if

this occurs. All other VDC functions are off
and the

indicator light will not flash.

The VDC system is automatically reset to
on when the ignition switch is placed in the
OFF position then back to the ON position.

The computer has a built-in diagnostic fea-
ture that tests the system each time you
start the engine and move the vehicle for-
ward or in reverse at a slow speed. When
the self-test occurs, you may hear a clunk
noise and/or feel a pulsation in the brake
pedal. This is normal and is not an indica-
tion of a malfunction.

WARNING

∙ The VDC system is designed to help

the driver maintain stability but does
not prevent accidents due to abrupt
steering operation at high speeds or
by careless or dangerous driving
techniques. Reduce vehicle speed and
be especially careful when driving and
cornering on slippery surfaces and al-
ways drive carefully.

∙ Do not modify the vehicle’s suspen-

sion. If suspension parts such as
shock absorbers, struts, springs, sta-
bilizer bars, bushings and wheels are
not NISSAN recommended for your
vehicle or are extremely deteriorated,
the VDC system may not operate
properly. This could adversely affect
vehicle handling performance, and
the

indicator light may flash or

the

indicator

light

may

illuminate.

∙ If brake related parts such as brake

pads, rotors and calipers are not
NISSAN recommended or are ex-
tremely deteriorated, the VDC system

indi-

cator light may illuminate.

∙ When driving on extremely inclined

surfaces such as higher banked cor-
ners, the VDC system may not operate
properly and the

indicator light

may flash or the

indicator light

may illuminate. Do not drive on these
types of roads.

∙ When driving on an unstable surface

such as a turntable, ferry, elevator or
ramp, the

indicator light may

flash or the

indicator light may

illuminate. This is not a malfunction.
Restart the engine after driving onto
a stable surface.

∙ If wheels or tires other than the

NISSAN recommended ones are used,
the VDC system may not operate
properly and the

indicator light

may flash or the

indicator light

may illuminate.

∙ The VDC system is not a substitute for

winter tires or tire chains on a snow
covered road.

RISE-UP AND BUILD-UP

The system gradually adjusts braking
power during normal braking to help pro-
vide an enhanced brake feel.

FREEING A FROZEN DOOR LOCK

To prevent a door lock from freezing, apply
de-icer through the key hole. If the lock
becomes frozen, heat the key before in-
serting it into the key hole, or use the re-
mote keyless entry key fob or the NISSAN
Intelligent Key®.

ANTIFREEZE

In the winter when it is anticipated that the
temperature will drop below 32°F (0°C),
check the antifreeze to assure proper win-
ter protection. For additional information,
refer to “Engine cooling system” in the “Do-
it-yourself ” section of this manual.

BATTERY

If the battery is not fully charged during
extremely cold weather conditions, the
battery fluid may freeze and damage the
battery. To maintain maximum efficiency,
the battery should be checked regularly.
For additional information, refer to “Battery”
in the “Do-it-yourself ” section of this
manual.

DRAINING OF COOLANT WATER

If the vehicle is to be left outside without
antifreeze, drain the cooling system, includ-
ing the engine block. Refill before operating
the vehicle. For additional information, refer
to “Changing engine coolant” in the “Do-it-
yourself ” section of this manual.

TIRE EQUIPMENT

1. SUMMER tires have a tread designed to

provide superior performance on dry
pavement. However, the performance
of these tires will be substantially re-
duced in snowy and icy conditions. If
you operate your vehicle on snowy or
icy roads, NISSAN recommends the use
of MUD & SNOW or ALL SEASON TIRES
on all four wheels. It is recommended
that you visit a NISSAN dealer for the tire
type, size, speed rating and availability
information.

2. For additional traction on icy roads,

studded tires may be used. However,
some U.S. states and Canadian prov-
inces prohibit their use. Check local,
state and provincial laws before install-
ing studded tires.

Skid and traction capabilities of studded
snow tires on wet or dry surfaces may be
poorer than that of non-studded snow
tires.

3. Tire chains may be used. For additional

information, refer to “Tire chains” in the
“Do-it-yourself ” section of this manual.

SPECIAL WINTER EQUIPMENT

It is recommended that the following items
be carried in the vehicle during winter:

∙ A scraper and stiff-bristled brush to re-

move ice and snow from the windows
and wiper blades.

∙ A sturdy, flat board to be placed under

the jack to give it firm support.

∙ A shovel to dig the vehicle out of snow-

drifts.

∙ Extra

washer

fluid

refill

the

windshield-washer fluid reservoir.

COLD WEATHER DRIVING

5-78

Starting and driving

DRIVING ON SNOW OR ICE

WARNING

∙ Wet ice (32°F, 0°C and freezing rain), very

cold snow or ice can be slick and very
hard to drive on. The vehicle will have
much less traction or “grip” under these
conditions. Try to avoid driving on wet
ice until the road is salted or sanded.

∙ Whatever the condition, drive with

caution. Accelerate and slow down
with care. If accelerating or down-
shifting too fast, the drive wheels will
lose even more traction.

∙ Allow more stopping distance under

these conditions. Braking should be
started sooner than on dry pavement.

∙ Allow greater following distances on

slippery roads.

∙ Watch for slippery spots (glare ice).

These may appear on an otherwise
clear road in shaded areas. If a patch
of ice is seen ahead, brake before
reaching it. Try not to brake while on
the ice, and avoid any sudden steering
maneuvers.

∙ Do not use the cruise control (if so

equipped) on slippery roads.

∙ Snow can trap dangerous exhaust

gases under your vehicle. Keep snow
clear of the exhaust pipe and from
around your vehicle.

ENGINE BLOCK HEATER (if so
equipped)

Engine block heaters are used to assist
with cold temperature starting.

The engine block heater should be used
when the outside temperature is 20°F (-7°C)
or lower.

WARNING

∙ Do not use your engine block heater

with an ungrounded electrical system
or a 2-pronged adapter. You can be
seriously

injured

electrical

shock if you use an ungrounded
connection.

∙ Disconnect and properly store the en-

gine block heater cord before starting
the engine. Damage to the cord could
result in an electrical shock and can
cause serious injury.

∙ Use a heavy-duty 3-wire, 3-pronged ex-

tension cord rated for at least 10 A. Plug
the extension cord into a Ground Fault
Interrupt (GFI) protected, grounded
110-VAC outlet. Failure to use the proper
extension cord or a grounded outlet
can result in a fire or electrical shock
and cause serious personal injury.

To use the engine block heater:

1. Turn the engine off.

2. Open the hood and unwrap the engine

block heater cord.

3. Plug the engine block heater cord into

a grounded 3-wire, 3-pronged exten-
sion cord.

4. Plug the extension cord into a Ground

Fault

Interrupt

(GFI)

protected,

grounded 110-volt AC (VAC) outlet.

5. The engine block heater must be

plugged in for at least 2 - 4 hours, de-
pending on outside temperatures, to
properly warm the engine coolant. Use
an appropriate timer to turn the engine
block heater on.

6. Before starting the engine, unplug and

properly store the cord to keep it away
from moving parts.
