Driving
CAUTION
■The ABS/Multi Terrain ABS does not operate effectively when
●The limits of tire gripping performance have been exceeded (such as excessively
worn tires on a snow covered road).
●The vehicle hydroplanes while driving at high speed on the wet or slick road.
■Stopping distance when the ABS/Multi Terrain ABS is operating may exceed that of
normal conditions
The ABS/Multi Terrain ABS is not designed to shorten the vehicle’s stopping distance.
Always maintain a safe distance from the vehicl e in front of you, especially in the follow-
ing situations:
●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 potholes or uneven surfaces
■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 system 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 control. The hill-start assist control may not
operate effectively on steep inclines and roads covered with ice.
■When the VSC/Trailer Sway Control is activated
The slip indicator light flashes and a warn ing buzzer sounds. Always drive carefully.
Reckless driving may cause an accident. Exercise particular care when the indicator
light flashes and a buzzer sounds.
■When the TRAC or Active TRAC/VSC/Trailer Sway Control systems are turned off
Be especially careful and drive at a speed appropriate to the road conditions. As these
are the systems to help ensure vehicle stab ility and driving force, do not turn the TRAC
or Active TRAC/VSC/Trailer Sway Control systems off unless necessary.

CAUTION
■Replacing tires
Make sure that all tires are of the same size, brand, tread pattern and total load capac-
ity. In addition, make sure that the tires are inflated to the recommended tire inflation
pressure level.
The ABS/Multi Terrain ABS, TRAC/Active
TRAC and VSC/Trailer Sway Control will
not function correctly if different tires are installed on the vehicle.
Contact your Lexus dealer for further information when replacing tires or wheels.
■Handling of tires and the suspension
Using tires with any kind of problem or modi fying 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 situations.
Depending on many factors such as the conditions of the vehicle, trailer, road surface,
and driving environment, the Trailer Sway Control system 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. 1 8 0 )

PCS (Pre-Collision system)∗
◆Pre-collision seat belts (front seat belts only)
If the system detects that a collision is unavoidable, the system will retract the
seat belt before the collision occurs.
The same will happen if the driver makes an emergency braking or loses con-
trol of the vehicle. (
→P. 2 9 )
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 relation 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 deter-
mines that a collision is unavoidable, the brakes are automatically applied to
reduce the collision speed. Pre-collision braking can be disabled using the
pre-collision braking off switch.
◆AVS (Adaptive Variable Suspension System) control (if equipped)
When the system determines that there is a high possibility of a frontal colli-
sion, the AVS optimizes the damping effect ( →P. 3 3 5 )
∗: If equipped
When the radar sensor detects possibility of a frontal collision, the pre-colli-
sion system such as the brakes and seat belts are automatically engaged to
lessen impact as well as vehicle damage.
