When the brake system operates continuously
The brake system may overheat. In this case, a buzzer will sound, the “TRAC OFF”
will be displayed on the multi-information display, and Multi-terrain Select will be
temporarily inoperable. In this event, stop the vehicle immediately in a safe place,
and allow the brake system to cool down sufficiently. (There is no problem with
continuing normal driving.)
After a short time, the message on the multi-information display will go off, and you
will be able to use Multi-terrain Select. ■
When there is a malfunction in the system
The slip indicator light will come on. Have the vehicle inspected by your Lexus
dealer immediately.
CAUTION■
When using the Multi-terrain Select
Observe the following precautions to avoid an accident that could result in death or
serious injuries: ●
There is a chance that the selected mode may not be the most appropriate in
terms of road conditions such as pi tch, slipperiness, undulation, etc. (  P. 345)●
Multi-terrain Select is not intended to expand the limits of the vehicle. Check the
road conditions thoroughly beforeha nd, and drive safely and carefully.

LX570_OM_OM60L96U_(U) When the VSC/Trailer Sway Cont rol/Active TRAC/hill-start assist
control systems are operating
The slip indicator light flashes to
indicate that the VSC/Trailer
Sway Control/Active TRAC/hill-
start assist control systems have
been engaged. The stop lights and high mounted
stoplight turn on when the hill-start
assist control system or Trailer
Sway Control is operating.■ Trailer Sway Control Helps the driver to control trailer sway by selectively applying brake pres-
sure for individual wheels and reducing engine torque when trailer sway is
detected.
Trailer Sway Control is part of th e VSC system and will not operate if
VSC turned off or expe riences a malfunction.

Sounds and vibrations caused by the Multi Terrain ABS, brake assist, Active
TRAC, VSC, Trailer Sway Control, hill-start assist control and VGRS●
A sound may be heard from the engine 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 any of these systems. ●
Any of the following conditions may oc cur when the above systems are operat-
ing. None of these indicates 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.
• The brake pedal may pulsate slightly after the Multi Terrain ABS is activated.
• The brake pedal may move down slightly after the Multi Terrain ABS is acti-
vated.■
Hill-start assist control is operational when ●
The shift lever is in “D” or “S”. ●
The brake pedal is not depressed.■
VGRS is disabled in the following situations ●
During stopping or the steering wheel has been moved for a long time while
driving at lower speeds. ●
After the engine is restarted at less than -22°F (-30°C).●
If you disconnect the battery with the steering wheel turned, the center position
of the steering wheel could be slightly and temporary changed. To initialize the
VGRS, drive for a short while.

When driving
LX570_OM_OM60L96U_(U) CAUTION■
When Active TRAC, VSC and Trailer Sway Control are off
Be especially careful and drive at a speed appropriate to the road conditions. As
these are systems to help to ensure vehicle stability and driving force, do not turn off
Active TRAC, VSC and Trailer Sway Control unless necessary. ■
When the VSC and Trailer Sway Control are activated
The slip indicator light flashes. Always drive carefully.
Reckless driving may cause an accident. Exercise particular care when the indica-
tor light flashes. ■
Replacing tires
Make sure that all tires ar e of the same size, brand, tread pattern and total load
capacity. In addition, make sure that the ti res are inflated to the specified tire pres-
sure level.
The Multi Terrain ABS, Active TRAC, VSC and Trailer Sway Control will not func-
tion correctly if different tire s are fitted on the vehicle.
Contact your Lexus dealer for further info rmation when replacin g tires or wheels.■
Handling of tires and suspension
Using tires with any kind of problem or mod ifying the suspension wi ll affect the driv-
ing assist systems, and may ca use the system to malfunction.

When driving
LX570_OM_OM60L96U_(U) Pre-Collision System 
 : If equippedWhen the radar sensor detects possibilit y of a frontal collision, the pre-col-
lision systems such as the brakes and seat belts are automatically engaged
to lessen impact as well as vehicle damage.
■ Pre-collision seat belts (front seats only) If the pre-collision sensor detects that a collision is unavoidable, the pre-
collision system will retract the seat belt before the collision occurs.
The same will happen if the driver makes an emergency braking or loses
control of the vehicle. (  P. 94)
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. The system may not warn the driver using a warning light,
warning display and buzzer when the system detects and judges braking
operations.
■ AVS control When the system determines that there is a high possibility of a frontal col-
lision, the AVS optimizes the damping effect. (  P. 331)

3582-4. Using other driving systems
LX570_OM_OM60L96U_(U) Radar sensor
Detects vehicles or other obsta-
cles on or near the road ahead and
determines whether a collision is
imminent based on the position,
speed, and heading of the obsta-
cles.When traveling on a road with very light traffic and very little to reflect the radar
waves emitted by the radar sensor, the system may decide that the radar sensor
is dirty, even if the sensor is not actually dirty. The system will automatically
restore itself when reflecte d radar waves are detected.■
Obstacles not detected
The sensor cannot detect plastic obstacles such as pylons. There may also be occa-
sions when the radar sensor cannot detect pedestrians, animals, bicycles, motorcy-
cles, trees, or snowdrifts. ■
The pre-collision system is operational when ●
Pre-collision seat belts (situation 1)
• Vehicle speed is greater than about 4 mph (5 km/h).
• The speed at which your vehicle is ap proaching the obstacle or the vehicle
running ahead of you is greate r than about 19 mph (30 km/h).
• The front occupants are wearing a seat belt. ●
Pre-collision seat belts (situation 2)
• Vehicle speed is greater than about 19 mph (30 km/h).
• The system detects sudd en braking or skidding.
• The front occupants are wearing a seat belt.

LX570_OM_OM60L96U_(U) ■
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 heavy rain, fog, snow or sand storms ●
When your vehicle is skidding such as the VSC system off●
When your vehicle is steeply inclined ●
When the axis of the radar is out of adjustment■
Automatic cancelation of the pre-collision system
When a malfunction occurs due to sensor contamination, etc. that results in the
sensors being unable to detect obstacles, the pre-collision system will be automati-
cally disabled. In this case, th e system will not activate even if there is a collision pos-
sibility. ■
When there is a malfunction in the system, or if the system is temporarily unus-
able
Warning lights and/or warning messa ges will turn on or flash. (  P. 826, 837)
