or 1 km/h

(0.6 mph)

increments for as long as the lever is held



For Canada, Guam, Saipan, Samoa and Puerto Rico

Fine adjustment: By 1 mph (1.6 km/h)

or 1 km/h (0.6 mph)

each time

the lever is operated
Large adjustment: Increases or decreases in 5 mph (8 km/h)

or 5 km/h

(3.1 mph)

increments for as long as the lever is held

In the constant speed control mode (

P. 260), the set speed will be

increased or decreased as follows:

Fine adjustment: By 1 mph (1.6 km/h)

or 1 km/h (0.6 mph)

The  vehicle-to-vehicle  distance  is
set  automatically  to  long  mode
when the engine switch is turned to
the “ON” position.
If  a  vehicle  is  running  ahead  of
you,  the  preceding  vehicle  mark
will also be displayed.

Select a distance from the table below. Note that the distances shown
correspond to a vehicle speed of 50 mph (80 km/h). Vehicle-to-vehicle
distance increases/decreases in accordance with vehicle speed.

Pulling the lever toward you
cancels the speed control.

The speed control is also canceled
when

the

brake

pedal

depressed.

Pushing the lever up resumes
the cruise control and returns
vehicle speed to the set speed.

However, cruise control does not resume when the vehicle speed is
approximately 25 mph (40 km/h) or less.

When your vehicle is too close to
a  vehicle  ahead,  and  sufficient
automatic  deceleration  via  the
cruise  control  is  not  possible,  the
display  will  flash  and  the  buzzer
will  sound  to  alert  the  driver.  An
example  of  this  would  be  if
another driver cuts in front of you
while you are following a vehicle.
Depress  the  brake  pedal  to
ensure  an  appropriate  vehicle-to-
vehicle distance.

■

Warnings may not occur when
In the following instances, warnings may not occur even when the
vehicle-to-vehicle distance is small.
● When the speed of the preceding vehicle matches or exceeds

your vehicle speed

● When the preceding vehicle is traveling at an extremely slow

speed

● Immediately after the cruise control speed was set
● When depressing the accelerator pedal

4-5. Using the driving support systems

When constant speed control mode is selected, your vehicle will main-
tain a set speed without controlling the vehicle-to-vehicle distance.
Select this mode only when vehicle-to-vehicle distance control mode
does not function correctly due to a dirty radar sensor, etc.

With the cruise control off,
press and hold the “ON-OFF”
button for 1.5 seconds or more.

Immediately  after  the  “ON-OFF”
button is pressed, the radar cruise
control  indicator  will  come  on.
Afterwards, it switches to the cruise
control indicator.
Switching  to  constant  speed  con-
trol  mode  is  only  possible  when
operating  the  lever  with  the  cruise
control off.

Accelerate  or  decelerate,  with
accelerator  pedal  operation,  to
the desired vehicle speed (at or
above  approximately  30  mph
[50  km/h])  and  push  the  lever
down to set the speed.

Cruise  control  “SET”  indicator  will
come on.
The  vehicle  speed  at  the  moment
the  lever  is  released  becomes  the
set speed.

■

Dynamic radar cruise control can be set when

●

The shift lever is in D or range 4 or higher of S has been selected.

●

Vehicle speed is at or above approximately 30 mph (50 km/h).

■

Accelerating after setting the vehicle speed
The vehicle can accelerate by operating the accelerator pedal. After acceler-
ating, the set speed resumes. However, during vehicle-to-vehicle distance
control mode, the vehicle speed may decrease below the set speed in order
to maintain the distance to the preceding vehicle.

■

Automatic cancelation of vehicle-to-vehicle distance control mode
Vehicle-to-vehicle distance control mode is automatically canceled in the fol-
lowing situations:

●

Actual vehicle speed falls at or below approximately 25 mph (40 km/h).

●

VSC is activated.

●

TRAC is activated for a period of time.

●

When the VSC or TRAC system is turned off.

●

The sensor cannot detect correctly because it is covered in some way.

●

Pre-collision braking is activated.

If vehicle-to-vehicle distance control mode is automatically canceled for any
other reason, there may be a malfunction in the system. Contact your Toyota
dealer.

■

Automatic cancelation of constant speed control mode
Constant speed control mode is automatically canceled in the following situa-
tions:

●

Actual vehicle speed is more than approximately 10 mph (16 km/h) below
the set vehicle speed.

●

Actual vehicle speed falls below approximately 25 mph (40 km/h).

●

VSC is activated.

●

TRAC is activated for a period of time.

●

When the VSC or TRAC system is turned off.

●

Pre-collision braking is activated.

If constant speed control mode is automatically canceled for any other rea-
son, there may be a malfunction in the system. Contact your Toyota dealer.

■

Brake system operation sound
If the brakes are applied automatically while the vehicle is in vehicle-to-vehi-
cle distance control mode, a brake system operation sound may be heard.
This does not indicate a malfunction.

■

Warning messages and buzzers for dynamic radar cruise control
Warning messages and buzzers are used to indicate a system malfunction or
to inform the driver of the need for caution while driving. If a warning message
is shown on the multi-information display, read the message and follow the
instructions.

■

When the sensor may not be correctly detecting the vehicle ahead
In the case of the following and depending on the conditions, operate the
brake pedal when deceleration of the system is insufficient or operate the
accelerator pedal when acceleration is required.
As the sensor may not be able to correctly detect these types of vehicles, the
approach warning (

P. 259) may not be activated.

●

Vehicles that cut in suddenly

●

Vehicles traveling at low speeds

●

Vehicles that are not moving in the same lane

●

Vehicles with small rear ends (trailers with no load on board, etc.)

●

(caused by a heavy load in the luggage
compartment, etc.)

Conditions under which the vehicle-to-vehicle distance control mode
may not function correctly
In the case of the following conditions, operate the brake pedal (or accelera-
tor pedal, depending on the situation) as necessary.
As the sensor may not be able to correctly detect vehicles ahead, the system
may not operate properly.

●

When the vehicle ahead of you decelerates suddenly

●

When driving on a road surrounded by a structure, such as in a tunnel or on
a bridge

●

While the vehicle speed is decreasing to the set speed after the vehicle
accelerates by depressing the accelerator pedal

●

When the road curves or when the lanes
are narrow

●

When steering wheel operation or your
position in the lane is unstable

WARNING

■

When using the intuitive parking assist
Observe the following precautions.
Failure to do so may result in the vehicle being unable to be driven safely
and possibly cause an accident.

●

Do not use the sensor at speeds in excess of 6 mph (10 km/h).

●

The sensors’ detection areas and reaction times are limited. When moving
forward or reversing, check the areas surrounding the vehicle (especially
the sides of the vehicle) for safety, and drive slowly, using the brake to
control the vehicle’s speed.

●

Do not install accessories within the sensors’ detection areas.
