You can turn off the traction control system by
pushing the ªTRAC OFFº switch. The ªTRAC OFFº
indicator/warning light will then come on. Pushing
the ªTRAC OFFº switch a second time turns the
system back on and extinguishes the ªTRAC OFFº
indicator/warning light.
You may hear a sound in the engine compartment for a
few seconds when the engine is started or just after the
vehicle is started. This means that the traction control
system is in the self
±check mode, and does not indicate
malfunction.
When the traction control system is operating, you may
feel vibration or noise of your vehicle, caused by
operation of the brakes. This indicates the system is
functioning properly.
When getting the vehicle out of mud or new snow, etc.
the traction control system will help operate to prevent
the wheels from spinning.
Traction control failure warning
The ªTRAC OFFº indicator/warning light warns that
when there is a problem somewhere in the traction
control system.
The light will come on when the ignition key is turned to
ªONº, and will go off after a few seconds.
If either of the following conditions occurs, this indicates
malfunction somewhere in the parts monitored by the
warning light system. Contact your Lexus dealer as
soon as possible to service the vehicle.
The light does not come after the ignition is turned to
on.
The light is left on after the ignition is turned to on.
The light comes on while driving without pushing
ªTRAC OFFº switch.
The light flashes.
CAUTION
Under certain slippery road conditions, full traction of
the vehicle and power to the front wheels cannot be
maintained, even though the traction control system is
in operation. Do not drive the vehicle under any speed
or maneuvering conditions which will cause the vehicle
to lose traction. In situations where the road surface is
covered with ice or snow, your vehicle should be fitted
with snow tires or tire chains. Always drive at an
appropriate and cautious pace.

VEHICLE SKID CONTROLSYSTEM
The vehicle skid control system helps provide
comprehensive control of the systems such as an
anti±lock brake system, brake assist system,
traction control, engine control, etc. This system
automatically controls the output of the brakes or
engine to help prevent the vehicle from skidding
when cornering on a slippery road surface or abrupt
steering wheel operation occurs.

Slip indicator light
If the vehicle is going to skid during driving, the slip
indicator light flashes and an alarm sounds
intermittently.
The vehicle skid control activates when the vehicle
speed is about more than 15 km/h (9 mph). You may hear a sound in the engine compartment for a
few seconds when the engine is started or just after the
vehicle is started. This means that the vehicle skid
control is in the self±check mode and does not indicate
a malfunction.

You can turn off the vehicle skid control system by
pushing the ªVSC OFFº switch. The ªVSC OFFº
indicator comes on. At this time, the traction control
system also turns off. You cannot turn off either one
of them. Pushing the ªVSC OFFº switch a second
time turns the system back on and extinguishes the
ªVSC OFFº indicator light.
When you turn the ignition switch on, this system always

STARTING AND DRIVING
306These lights warn that there is a problem somewhere in
the vehicle skid control system, traction control system
or brake assist system.
The lights will come on when the ignition key is turned to
ªONº, and will go off after a few seconds.
If the ªVSCº warning light and ªVSC OFFº indicator light
come
on, the vehicle skid control system, traction control
system and brake assist system do not work. However,
as conventional braking operates when applied, there is
no problem to continue your driving.
If either of the following conditions occurs, this indicates
a malfunction somewhere in the parts monitored by the
warning light system. Contact your Lexus dealer as
soon as possible to service the vehicle:
The ªVSCº warning light and/or ªVSC OFFº indicator
light do/does not come on after the ignition is turned
to on.
The ªVSCº warning light and ªVSC OFFº indicator
light are left on after the ignition is turned to on.
The ªVSCº warning light and ªVSC OFFº indicator
light come on while driving without pushing ªVSC
OFFº switch.

CAUTION
Do not rely excessively on the vehicle skid control
system. Even if the vehicle skid control system is
operating, it is not that your vehicle is absolutely
safe. Reckless driving will result in an unexpected
accident. Always keep safety driving in mind. If the
slip indicator light flashes, sounding an alarm,
special care should be taken while driving.
Only use tires of specified size. The size,
manufacturer, brand and tread pattern for all 4 tires
should be the same. If you use the tires other than
specified, or different type or size, the vehicle skid
control system may not function correctly. When
replacing the tires or wheels, contact your Lexus
dealer.

BRAKE SYSTEM
The tandem master cylinder brake system is a hydraulic
system with two separate sub±systems. If either
sub±system should fail, the other will still work.
However, the pedal will be harder to press, and your
stopping distance will be longer. Also, the brake system
warning light may come on.
CAUTION
Do not drive your vehicle with only a single brake
system. Have your brakes fixed immediately.
Brake booster
The brake booster uses engine vacuum to power±assist
the brakes. If the engine should quit while you are
driving, you can bring the vehicle to a stop with normal
pedal pressure. There is enough reserved vacuum for
one or two stops but no more!

ªABSº warning light
31E068
The light comes on when the ignition key is turned to the
ªONº position. If the anti±lock brake system and the
brake
assist system work properly, the light turns off after
a few seconds. Thereafter, if either of the systems
malfunctions, the light comes on again.
When the ªABSº warning light is on (and the brake
system warning light is off), the anti±lock brake system,
the brake assist system, the traction control system and
the vehicle skid control system do not operate, but the
brake system still operates conventionally.
When the ªABSº warning light is on (and the brake
system warning light is off), the anti±lock brake system
does not operate so that the wheels could lock up during
a sudden braking or braking on slippery road surfaces. If either of the following conditions occurs, this
indicates a malfunction somewhere in the parts
monitored by the warning light system. Contact
your
Lexus dealer as soon as possible to service the
vehicle.
The light does not come on when the ignition key is
turned to the ªONº position, or remains on.
The light comes on while you are driving.
A warning light turning on briefly during operation does
not indicate a problem.
