■Cruise control can be set when
●The shift position is in D.
● Vehicle speed is above approximately 40 km/h (25 mph).
■ Accelerating after setting the vehicle speed
●The vehicle can be accelerated normally. After acceleration, the set speed
resumes.
● Even without canceling the cruise control, the set speed can be increased
by first accelerating the vehicle to the desired speed and then pushing the
lever down to set the new speed.
■ Automatic cruise control cancelation
Cruise control will stop maintaining the vehicle speed in any of the following
situations.
●Actual vehicle speed falls more than approximately 16 km/h (10 mph) below
the preset vehicle speed.
At this time, the memorized set speed is not retained.
● Actual vehicle speed is below approximately 40km/h (25 mph).
● VSC is activated.
■ If the cruise control indicator light comes on in yellow (vehicles without
multi-information display)
Press the “ON-OFF” button once to deactivate the system, and then press
the button again to reactivate the system.
If the cruise control speed cannot be set or if the cruise control cancels imme-
diately after being activated, there may be a malfunction in the cruise control
system. Have the vehicle inspected by any authorized Toyota dealer or
repairer, or another duly qualified and equipped professional.
■ If the warning message for the cruise control is shown (vehicles with
multi-information display)
Press the “ON-OFF” button once to deactivate the system, and then press
the button again to reactivate the system.
If the cruise control speed cannot be set or if the cruise control cancels imme-
diately after being activated, there may be a malfunction in the cruise control
system. Have the vehicle inspected by any authorized Toyota dealer or
repairer, or another duly qualified and equipped professional.

Dynamic radar cruise control∗
Dynamic radar cruise control supplements conventional cruise control
with a vehicle-to-vehicle distance control. In vehicle-to-vehicle dis-
tance control mode, the vehicle automatically accelerates or deceler-
ates in order to maintain a set following distance from vehicles ahead.Vehicle-to-vehicle distance but-

To change the set speed, operate the lever until the desired set speed
is displayed.Increases the speed
Decreases the speed
Fine adjustment: Momentarily
move the lever in the desired direc-
tion.
Large adjustment: Hold the lever in
the desired direction.
In the vehicle-to-vehicle distance control mode, the set speed will be
increased or decreased as follows:
XWhen the set speed is shown in “km/h”
Fine adjustment: By approximately 5 km/h (3.1 mph) each time the lever
is operated
Large adjustment: By approximately 5 km/h (3.1 mph) for each 0.75
seconds the lever is held
XWhen the set speed is shown in “MPH”
Fine adjustment: By approximately 5 mph (8 km/h) each time the lever
is operated
Large adjustment: By approximately 5 mph (8 km/h) for each 0.75 sec-
onds the lever is held
In the constant speed control mode ( →P. 239), the set speed will be
increased or decreased as follows:
Fine adjustment: By approximately 1.6 km/h (1 mph) each time the lever is
operated
Large adjustment: The set speed can be increased or decreased continu-
ally until the lever is released.

When your vehicle is too close to a vehicle ahead, and sufficient auto-
matic 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 follow-
ing a vehicle. Apply the brakes to ensure an appropriate vehicle-to-
vehicle distance.
■Warnings may not occur when
In the following instances, there is a possibility that the warnings will
not occur:
●When the speed of the vehicle ahead matches or exceeds your
vehicle speed
● When the vehicle ahead is traveling at an extremely slow speed
● Immediately after the cruise control speed was set
● At the instant the accelerator is applied

PCS (Pre-Crash Safety system)∗
◆Pre-crash warning
When a high possibility of a
frontal collision is detected, a
buzzer sounds and a message
is shown on the multi-informa-
tion display to urge the driver to
take evasive action.
◆Pre-crash brake assist
When there is a high possibility of a frontal collision, the system
applies greater braking force in relation to how strongly the brake
pedal is depressed.
◆Pre-crash braking
When there is a high possibility of a frontal collision, the system
warns the driver using a warning display and buzzer. If the system
determines that a collision is unavoidable, the brakes are automati-
cally applied to reduce the collision speed.
∗: If equipped
When the radar sensor detects possibility of a frontal collision,
brakes are automatically engaged to lessen impact as well as
vehicle damage.The alert timing for the pre-crash safety system can be changed or
turned ON/OFF, as necessary, by operating the switch. ( →P. 255)

Automatic cancelation of the pre-crash safety system
When a malfunction occurs due to sensor contamination, etc. that results in
the sensors being unable to detect obstacles, the pre-crash safety system will
be automatically disabled. In this case, the system will not activate even if
there is a collision possibility.
■ When there is a malfunction in the system, or if the system is tempo-
rarily unusable
The PCS warning light flashes and a warning message is shown on the multi-
information display. If a warning message is shown on the multi-information
display, read the message and follow the instructions. ( →P. 376, 388)
