Decreases the speed
Fine adjustment: Momentarily
move the lever in the desired direc-
tion.
Large adjustment: Hold the lever in
the desired direction.
The set speed will be increased or decreased as follows:
Fine adjustment: By approximately 1 mph (1.6 km/h) or 1 km/h (0.6 mph)
each time the lever is operated.
Large adjustment: The set speed can be increased or decreased continu-
ally until the lever is released.
Pulling the lever toward you
cancels the constant speed
control.
The speed setting is also canceled
when the brake pedal is
depressed.
Pushing the lever up resumes
the constant speed control.
However, resuming is available
when the vehicle speed is more
than approximately 25 mph
(40 km/h).

■Cruise control can be set when
●The shift position is in D.
● Vehicle speed is above approximately 25 mph (40 km/h).
■ Accelerating after setting the vehicle speed
●The vehicle can be accelerated by operating accelerator pedal. After accel-
erating, 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 cancelation of cruise control
Cruise control is automatically canceled in any of the following situati\
ons.
●Actual vehicle speed falls more than approximately 10 mph (16 km/h) below
the set speed.
At this time, the memorized set speed is not retained.
● Actual vehicle speed is below approximately 25 mph (40km/h).
● VSC is activated.
● TRAC is activated for a period of time.
● When the VSC or TRAC system is turned off by pressing the VSC OFF
switch.
● Intelligent Clearance Sonar is operated. (if equipped)
■ If “Check Cruise Control System Visit Your Dealer” is displayed on the
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 your Toyota dealer.

■Obstacle warning function
■ Obstacle detection in side areas
●Obstacles in the side areas are detec ted while driving by scanning the side
areas with the side sensors. Recognized obstacles are retained in memory
for up to approximately 2 minutes.
● Obstacles may not be detected in the side areas until the scan completes.
After the power switch is turned on, scanning completes after driving the
vehicle for a short period of time.
● When an obstacle such as another vehicle, pedestrian or animal is detected
by the side sensors, the obstacle may continue to be detected even after it
has left the side sensor detection area.
■ If “Clean Parking Assist Sensor” is displayed on the multi-information
display
A sensor may be dirty or covered with snow or ice. In such cases, if it is
removed from the sensor, the system should return to normal.
Also, due to the sensor being frozen at low temperatures, a malfunction dis-
play may appear or an obstacle may not be detected. If the sensor thaws out,
the system should return to normal.
■ If “Parking Assist Malf unction” is displayed on the multi-information dis-
play
Depending on the malfunction of the sensor, the device may not be working
normally. Have the vehicle inspected by your Toyota dealer.
■ Certification (Canada only)
This ISM device complies with Canadian ICES-001.
■ Customization
Setting of buzzer volume can be changed.
(Customizable features: P. 752)
When an obstacle in the side areas is
within the vehicle course while the vehicle
is moving forward or backward, this func-
tion inform the driver by the display and
the buzzer.

Driving
Accelerate the vehicle slowly, keep a safe distance between you and
the vehicle ahead, and drive at a reduced speed suitable to road con-
ditions.
Park the vehicle and shift the shift position to P and block the wheel
under the vehicle without setting the parking brake. The parking brake
may freeze up, preventing it from being released.
Use the correct tire chain size when mounting the tire chains. Chain
size is regulated for each tire size.
Side chain
0.12 in. (3.0 mm)
1.18 in. (30.0 mm)
0.39 in. (10.0 mm)
Cross chain 0.16 in. (4.0 mm)
0.98 in. (25.0 mm)
0.55 in. (14.0 mm)
Regulations regarding the use of tire chains vary depending on loca-
tion and type of road. Al ways check local regulations before installing
chains.
