■If the automatic transmission system overheats
The system will cease operation, a buzzer will sound and a warning message will be
displayed to alert the driver. Stop the vehi cle in a safe place until the warning mes-
sage turns off. ( P. 705)
■Sounds and vibrations caused by the Crawl Control system
●A sound may be heard from the engi ne compartment when the engine is
started or just after the vehicle begins to move. This sound does not indicate that
a malfunction has occurred in Crawl Control system.
●Either of the following conditions may occur when the Crawl Control system is
operating. None of these are indicators that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard after the vehicle comes to a stop.
■If the slip indicator comes on...
It may indicate a malfunction in th e system. Consult your Lexus dealer.
CAUTION
■When using Crawl Control
Do not rely solely on the Crawl Control. Th is function does not extend the vehicle’s
performance limitations. Always thoroughly check the road conditions, and drive
safely.
■These conditions may cause the system not to operate properly
When driving on the following surfaces, th e system may not be able to maintain a
fixed low speed, which may result in an accident:
●Extremely steep inclines.
●Extremely uneven surfaces.
●Snow-covered roads, or other slippery surfaces.

CAUTION
■TRAC/Active TRAC may not operate effectively when
Directional control and power may not be achievable while driving on slippery road
surfaces, even if the TRAC/Active TRAC is operating.
Do not drive the vehicle in conditions where stability and power may be lost.
■Hill- start assist control does not operate effectively when
Do not overly rely on the hill-start assist co ntrol. The hill-start assist control may not
operate effectively on steep incl ines and roads covered with ice.
■When the VSC is activated
The slip indicator light flashes and a warning buzzer sounds. Always drive carefully.
Reckless driving may cause an accident. Ex ercise particular care when the indica-
tor light flashes and a buzzer sounds.
■When the TRAC or Active TRAC/VSC systems are turned off
Be especially careful and drive at a speed appropriate to the road conditions. As
these are the systems to ensure vehicle stability and driving force, do not turn the
TRAC or Active TRAC/VSC systems off unless necessary.
■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 recommended tire
inflation pressure level.
The ABS/Multi Terrain ABS and VSC systems will not function correctly if different
tires are installed on the vehicle.
Contact your Lexus dealer for further info rmation when replacing tires or wheels.

PCS (Pre-Collision System)
: If equipped
When the radar sensor detects that a frontal collision is highly likely or
even unavoidable, safety systems such as the brakes and seat belts are
automatically engaged to lessen impact as well as vehicle damage.
■ Pre-collision seat belts (front seat belts only)
If the system detects that a collis ion is unavoidable, the system will
retract the seat belt be fore the collision occurs.
The same will happen if the driver makes an emergency braking or
loses control of the vehicle. ( P. 9 1 )
However, when the VSC system is disabled, the system will not
operate in the event of skidding.
■ Pre-collision brake assist
When there is a high possibility of a frontal collision, the system
applies greater braking force in rela tion to how strongly the brake
pedal is depressed.
■ Pre-collision braking
When there is a high possibility of a frontal collision, the system
warns the driver using a warning light, warning display and buzzer. If
the system determines that a collision is unavoidable, the brakes are
automatically applied to reduce the collision speed. Pre-collision
braking can be disabled using th e pre-collision braking off switch.

Disabling pre-collision brakingPre-collision braking disabled
Pre-collision braking enabled
The “PCS” warning light turns on
when pre-
collision braking is dis-
abled.
■ AVS (Adaptive Variable Suspension System) control (if equipped)
When the system determines that ther e is a high possibility of a fron-
tal collision, the AVS optimizes the damping effect ( P. 325)
■ Driver monitor system (if equipped)
When the system determines that there is a possibility of a frontal
collision, and the driver is not f acing forward, PCS warnings are
given in advance to warn the driver . If the driver continues to be not
facing forward, and a high possibilit y of a frontal collision is detected,
PCS informs the driver of high po ssibility of a frontal collision by
performing slight braking to provid e a physically warning (pre-colli-
sion alert braking). ( P. 3 4 9 )

■Situations in which the pre-collision system does not function properly
The system may not function effectively in situations such as the following:
●On roads with sharp bends or uneven surfaces
●If a vehicle suddenly moves in front of your vehicle, such as at an intersection
●If a vehicle suddenly cuts in front of your vehicle, such as when overtaking
●In inclement weather such as heav y rain, fog, snow or sand storms
●When your vehicle is skidding with the VSC system off
●When an extreme change in vehicle height occurs
●When the axis of the radar is out of adjustment
■Automatic cancelation of the pre-collision system
When a malfunction occurs due to sensor contaminations, etc. that results in the
sensors being unable to detect obstacles, the pre-collision system will be automati-
cally disabled. In this case, the system will not activate even if there is a collision pos-
sibility.
■Obstacles not detected
The system cannot detect plastic obstacles such as pylons. There may also be occa-
sions when the system cannot detect pede strians, animals, bicycles, motorcycles,
trees, or snowdrifts.
■When there is a malfunction in the system
Warning lights and/or warning mess ages will turn on or flash. (P. 693, 705)

CAUTION
■Driving with tire chains
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in the vehicle being unable to be driven safely, and may
cause death or serious injury.
●Do not drive in excess of the speed limit specified for the tire chains being used,
or 30 mph (50 km/h), whichever is lower.
●Avoid driving on bumpy road surfaces or over potholes.
●Avoid sudden turns and braking, as use of chains may adversely affect vehicle
handling.
●Slow down sufficiently before entering a curve to ensure that vehicle control is
maintained.
NOTICE
■Repairing or replacing snow tires
Request repairs or replacement of snow ti res from Lexus dealers or legitimate tire
retailers.
This is because the removal and attachment of snow tires affects the operation of
the tire pressure warning valves and transmitters.
■Fitting tire chains
The tire pressure warning valves and transmitters may not function correctly when
tire chains are fitted.
