STARTING AND DRIVING
303
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.

STARTING AND DRIVING
310The anti±lock brake system becomes operative after the
vehicle has accelerated to a speed in excess of
approximately 10 km/h (6 mph). It stops operating when
the vehicle decelerates to a speed below approximately
5 km/h (3 mph).
Depressing the brake pedal on slippery road surfaces
such as on the manhole cover, the steel plate under the
construction, joints in the bridge, etc. on a rainy day
tends to activate the anti±lock brake system.
You may hear a click or motor 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 anti±lock brake system is in the self±check
mode, and does not indicate a malfunction.
When the anti±lock brake system is activated, the
following conditions may occur. They do not
indicate a malfunction of the system:

You may hear the anti±lock brake system operating
and feel the brake pedal pulsating and the vibrations
of the vehicle body and steering wheel. You may also
hear the motor sound in the engine compartment
even after the vehicle is stopped.
 At the end of the anti±lock brake system activation,
the brake pedal may move a little forward.

DRIVING TIPS
339

Avoid continuous speeding up and slowing
down. Stop±and±go driving wastes fuel.
 Avoid unnecessary stopping and braking.
Maintain a steady pace. Try to time the traffic si gnals
so you only need to stop as little as possible or take
advantage of through streets to avoid traffic lights.
Keep a proper distance from other vehicles to avoid
sudden braking. This will also reduce wear on your
brakes.
 Avoid heavy traffic or traffic jams whenever
possible.
 Do not rest your foot on the brake pedal. This
causes premature wear, overheating and poor fuel
economy.
 Maintain a moderate speed on highways. The
faster you drive, the greater the fuel consumption. By
reducing your speed, you will cut down on fuel
consumption.
 Keep the front wheels in proper alignment. Avoid
hitting the curb and slow down on rough roads.
Improper alignment not only causes faster tire wear
but also puts an extra load on the engine, which, in
turn, wastes fuel.
 Keep the bottom of your vehicle free from mud
etc. This not only lessens weight but also helps
prevent corrosion. 
Keep your vehicle tuned±up and in top shape. A
dirty air cleaner, improper valve clearance, dirty
plugs, dirty oil and grease, brakes not adjusted, etc.
all lower engine performance and contribute to poor
fuel economy. For longer life of all parts and lower
operating costs, keep all maintenance work on
schedule, and if you often drive under severe
conditions, see that your vehicle receives more
frequent maintenance. (For scheduled maintenance
information, please refer to the ªOwner's Manual
Supplement/Maintenance Scheduleº.)
