When driving
CAUTION
■Conditions under which the vehicle -to-vehicle distance control may
not function correctly
Apply the brakes as necessary in the following conditions as the laser radar
sensor may not be able to correctly detect vehicles ahead, and a fatal or
serious accident may result.
● When water or snow thrown up by the surrounding vehicles hinders the
functioning of the sensor
● When your vehicle is pointing upwards (caused by a heavy load in the lug-
gage compartment etc.)
● When the road curves or when the lanes are narrow
● When steering wheel operation or your position in the lane is unstable
● When the vehicle ahead of you decelerates suddenly
● When your vehicle is towing a trailer or during emergency towing
■ Handling the laser radar sensor
Observe the following to ensure the cruise control system can function effec-
tively.
Otherwise, the system may not function correctly and could result in an acci-
dent.
●Keep the sensor clean at all times.
Clean the sensor with a soft cloth so you do not mark or damage them.
● Do not subject the sensor or surrounding area to a strong impact.
If the sensor moves even slightly off position, the system may malfunction.
If the sensor or surrounding area is subject to a strong impact, always
have the area inspected and adjusted by a Toyota dealer.
● Do not disassemble the sensor.
● Do not attach accessories or stickers to the sensor, surrounding area.
● Do not modify or paint the sensor.
● Do not replace them with non-genuine parts.

234 2-4. Using other driving systems
CAUTION
■When using the rear view monitor system
Observe the following precautions to avoid an accident that could result in
death or serious injuries.
● Never depend solely on the rear view monitor system when reversing.
● Always check visually and with the mirrors to confirm your intended path is
clear.
● Always check the vehicle surroundi ng area, because the guide lines are
estimates of distance and location.
● The guide lines are assistant lines and do not change even if the steering
wheel is turned.
● Depicted distances between objects and flat surfaces differ from actual
distances.
● Do not use the system if back door is open.
■ Conditions which may affect the rear view monitor system
● If the back of the vehicle has been hit, the camera’s position and mounting
angle may have changed. Have the vehicle inspected by your Toyota
dealer.
● Rapid temperature changes, such as when hot water is poured on the
vehicle in cold weather, may cause the system to function abnormally.
● If the camera lens is dirty, it cannot transmit a clear image. Rinse with
water and wipe with a soft cloth. If extremely dirty, wash with a mild
cleanser and rinse.
● The displayed image may be darker and moving images may be slightly
distorted when the system is cold.
■ Caution while driving in reverse
Do not change modes while the vehicle is moving.

2-4. Using other driving systems
AVS (Adaptive Variable Suspension System)
: If equipped
■Driving mode
●Sport mode is suitable for winding mountain road driving, high speed
driving or towing a trailer.
● Normal mode is suitable for ordinary driving.
AVS controls the suspension accord ing to the road and driving con-
ditions. Selecting an optimum driving mode allows good vehicle
posture and steering wheel operation.
Sport mode

If the rear wheels spin, the slip
indicator flashes to indicate that
the AUTO LSD system has con-
trolled the spinning of the rear
wheels.
■If the engine is turned off and restarted
The AUTO LSD system and the indicators are automatically turned off.
■ If the brake system overheats
The AUTO LSD system will cease operation, and the slip indicator will
change from flashing to being on continuously to alert the driver. Stop the
vehicle in a safe place. (There is no problem with continuing normal driving.)
The system will be automatically restored after a short time.
CAUTION
■To avoid an accident
●Do not use the AUTO LSD system in conditions other than the above.
A much greater steering effort and more careful cornering control will be
required.
● Do not drive with the AUTO LSD system continuously turned on.

258 2-4. Using other driving systems

■ Sounds and vibrations caused by the ABS, TRAC, A-TRAC, VSC,
Trailer Sway Control and brake assist system
●A sound may be heard from the engine compartment when the engine is
started and just after the vehicle begins to move. This sound does not
indicate that a malfunction has occurred in any of these systems.
● Any of the following conditions may occur when the above systems are
operating. None of these indicates that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.

■If the brake system overheats
TRAC or A-TRAC will cease operation, and the slip indicator will change
from flashing to being on continuously to alert the driver. Stop the vehicle in
a safe place. (There is no problem with continuing normal driving.)
■ Shifting to 4L position

matically turned off.
■ Power steering system operation sound
When you turn the engine switch to ON after the battery has been discon-
nected and reconnected, a sound may be heard from the engine compart-
ment.
This does not indicate a malfunction.
CAUTION
Any of the following conditions may result in an accident which could cause
death or serious injury.
■ The ABS does not opera te effectively when
● The limits of the gripping performance have been exceeded.
● The vehicle hydroplanes while driving at high speed on the wet or slick
road.
■ Stopping distance when the ABS is operating may exceed that of nor-
mal conditions
The ABS is not designed to shorten the vehicle’s stopping distance. Always
maintain a safe distance from the vehicle in front of you in the following situ-
ations.
● When driving on dirt, gravel or snow-covered roads
● When driving with tire chains
● When driving over bumps in the road
● When driving over roads with pothol es or roads with uneven roads
■ When VSC and Trailer Sway Control are activated

cause an accident. Exercise particular care when the indicator flashes.

260 2-4. Using other driving systems
CAUTION
■TRAC or A-TRAC may not operate effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if TRAC or A-TRAC is operating.
Do not drive the vehicle in conditions where stability and power may be lost.
■ Replacing tires
Make sure that all tires are of the same size, brand, tread pattern and total
load capacity. In addition, make sure that the tires are inflated to the appro-
priate tire pressure level.
The ABS, VSC and Trailer Sway Control will not function correctly if different
tires are fitted on the vehicle.
Contact your Toyota dealer for further information when replacing tires or
wheels.
■ Handling of tires and suspension
Using tires with any kind of problem or modifying the suspension will affect
the driving assist systems, and may cause the system to malfunction.
■ Trailer Sway Control precaution
The Trailer Sway Control system is not able to reduce trailer sway in all situ-
ations. Depending on many factors such as the conditions of the vehicle,
trailer, road surface, and driving environment, the Trailer Sway Control sys-
tem may not be effective. Refer to your trailer owner’s manual for information
on how to tow your trailer properly.
■ If trailer sway occurs
Observe the following precautions.
Failing to do so may cause death or serious injury.
●Firmly grip the steering wheel. Steer straight ahead.
Do not try to control trailer swaying by turning the steering wheel.
● Begin releasing the accelerator pedal immediately but very gradually to
reduce speed.
Do not increase speed. Do not apply vehicle brakes.
If you make no extreme correction with the steering or brakes, your vehicle
and trailer should stabilize. ( P. 292)
