You can turn off the traction control system by pushing
the ºTRAC OFFº switch. The ºTRAC OFFº
indicator/warning light will then come on. Pushing the
ºTRAC OFFº switch a second time turns the system back
on and extinguishes the ºTRAC 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 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.
If the light flashes, this indicates a malfunction in the traction
control system. Contact your Lexus dealer as soon as
possible to service the vehicle.
Traction control system failure warning
SV31035
These lights warn that there is a problem somewhere in the
vehicle skid control system or traction control system.
The lights will come on when the ignition key is turned to ºONº,
and will go off after a few seconds.
If the ºVSCº warning light and ºTRAC OFFº indicator/warning
light come on, the vehicle skid control system and traction
control system do not work. However, as conventional braking
operates when applied, there is no problem to continue your
driving.
If any 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 ºVSCº warning light or ºTRAC OFFº indicator/warning
light do not come on after the ignition is turned to on.

to service the vehicle:
 The ºVSCº warning light or ºTRAC OFFº indicator/warning
light do not come on after the ignition is turned to on.
 The ºVSCº warning light and ºTRAC OFFº indicator/warning
light remain on after the ignition is turned to on. 
The ºVSCº warning light and ºTRAC OFFº indicator/warning
light come on while driving without pushing ºTRAC OFFº
switch.
CAUTION
Do not rely excessively on the vehicle skid control
system. Even if the vehicle skid control system is
operating, you must always drive carefully and atten-
tively to avoid serious injury. Reckless driving will
result in an unexpected accident. If the slip indicator
light flashes, sounding an alarm, special care should
be taken while driving.
 Only use tires of specified size. The size, manufac-
turer, 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.

STARTING AND DRIVING
249
The light comes on when the ignition key is turned to the ºONº
position. If the anti±lock brake system and the brake assist
work properly, the light turns off after a few seconds.
Thereafter, if either of the systems malfunctions, the light
comes on again.
When the ºABSº 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/or the vehicle
skid control system do not operate, but the brake system still
operates conventionally.
When the ºABSº warning light is on (and the brake system
warning light is off), the anti±lock brake system and/or the
traction
control system do/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 ºONº 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.
CAUTION
If the ºABSº warning light remains on together with the
brake system warning light, immediately stop your
vehicle at a safe place and contact your Lexus dealer.
In this case, not only the anti±lock brake system will fail
but also the vehicle will become extremely unstable
during braking.
Drum±in±disc type parking brake system
Your vehicle has a drum±in±disc type parking brake system.
This type of brake system needs bedding±down of the brake
shoes periodically or whenever the parking brake shoes
and/or drums are replaced.
Have your Lexus dealer perform the bedding±down.
Brake assist system
When you slam the brakes on, the brake assist system
judges as an emergency stop and provides more powerful
braking for a driver who cannot hold down the brake pedal
firmly.
When you slam the brakes on, more powerful braking will be
applied. At this time, you may hear a sound in the engine
compartment and feel the vibrations of the brake pedal. This
does not indicate a malfunction.
The brake assist 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).

DRIVING TIPS

HOW TO SAVE FUEL AND MAKEYOUR VEHICLE LAST LONGER
Improving fuel economy is easy ± just take it easy. It will help
make your vehicle last longer, too. Here are some specific tips
on how to save money on both fuel and repairs:

Keep your tires inflated at the correct pressure. Check
the pressure every two weeks, or at least once a month.
Underinflation causes tire wear and wastes fuel.

Do not carry unneeded weight in your vehicle. Excess
weight puts a heavier load on the engine, causing greater
fuel consumption.

Avoid lengthy warm±up idling. Once the engine is
running smoothly, begin driving ± but gently. Remember,
however, that on cold winter days this may take a little
longer.

Accelerate slowly and smoothly. Avoid jackrabbit starts.

Avoid long engine idling. If you have a long wait and you
are not in traffic, it is better to turn off the engine and start
again later.

Avoid engine over±revving. Use a gear position suitable
for the road on which you are traveling.

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 traf fic signals 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.

IF YOUR ENGINE STALLS WHILEDRIVING
If your engine stalls while driving . . . .
1. Reduce your speed gradually, keeping a straight line.
Move cautiously off the road to a safe place.
2. Turn on your emergency flashers.
3. Try starting the engine again.
If the engine will not start, see ºIf your vehicle will not startº\
.
CAUTION
If the engine is not running, the power assist for the
brakes and steering will not work, so steering and
braking will be much harder than usual.
IF YOU CANNOT INCREASE THEENGINE SPEED
If the engine speed does not increase with the accelerator
pedal depressed down to about the middle position, there
may be a problem somewhere in your electronic throttle
control system.
At this time, if you depress the accelerator pedal more firmly
and slowly, you can drive you vehicle at low speeds. Have your
vehicle checked by your Lexus dealer as soon as possible.
Even if the abnorma lity of the electronic throttle control system
is corrected during low speed driving, the system may not be
recovered until the engine is stopped and the ignition key is
turned to ºACCº or ºLOCKº position.
CAUTION
Be especially careful to prevent erroneous pedal
operation.

IN CASE OF AN EMERGENCY
263
IF YOUR VEHICLE WILL NOTSTART
(a) Simple checks
Before making these checks, make sure you have followed the
correct starting procedure instructions in ºHow to start the
engineº on page 225 and that you have sufficient fuel. Since
your vehicle is equipped with the engine immobiliser system,
also check whether the other keys will start the engine. If they
work, your key may be broken. Have the key checked at your
Lexus dealer. If none of your keys work, the system is possibly
broken. Call your Lexus dealer. See ºKeysº on page 8.
If the engine is not turning over or is turning over too
slowly ±
1. Check that the battery terminals are tight and clean.
2. If the battery terminals are O.K., switch on the interior light.
3. If the light is out, dim or goes out when the starter is
cranked, the battery is discharged. You may try jump starting.
See º(c) Jump startingº for further instruction.
If the light is O.K., but the engine still will not start, it needs
adjustment or repair. Call a Lexus dealer, Roadside
Assistance or Customer Service Assistance. (See
ºForewordº.)
NOTICE
Do not pull± or push±start the vehicle. It may damage
the vehicle or cause a collision when the engine starts.Also the three±way catalytic converter may overheatand become a fire hazard.
If the engine turns over at its normal speed but will not
start ±
1. The engine may be flooded because of repeated cranking.
See º(b) Starting a flooded engineº for further instructions.
2. If the engine still will not start, it needs adjustment or repair.
Call a Lexus dealer, Roadside Assistance or Customer
Service Assistance. (See ºForewordº.)

IN CASE OF AN EMERGENCY
264
(b) Starting a flooded engine
If the engine will not start, your engine may be flooded
because of repeated cranking.
If this happens, turn the key to ºSTARTº with the accelerator
pedal held down. Continue this operation for 30 seconds and
then stop cranking. Then try starting the engine with your foot
off the accelerator pedal.
If the engine does not start after 30 seconds of cranking,
release the key, wait a few minutes and try again.
If the engine still will not start, it needs adjustment or repair.
Call a Lexus dealer, Roadside Assistance or Customer
Service Assistance. (See ºForewordº.)
NOTICE
Do not crank for more than 30 seconds at a time. This
may overheat the starter and wiring systems.
(c) Jump starting
To avoid serious personal injury and damage to your
vehicle which might result from battery explosion, acid
burns, electrical burns, or damaged electronic
components, these instructions must be followed
precisely.
If you are unsure about how to follow this procedure, we
strongly recommend that you seek help from your Lexus
dealer, Roadside Assistance or Customer Service Assistance.
(See ºForewordº.)
CAUTION
 Batteries contain sulfuric acid which is poisonous
and corrosive. Wear protective safety glasses when
jump starting, and avoid spilling acid on your skin,
clothing, or vehicle.
 If you should accidentally get acid on yourself or in
your eyes, remove any contaminated clothing and
flush the affected area with water immediately. Then
get immediate medical attention. If possible,
continue to apply water with a sponge or cloth while
en route to the medical office.
 The gas normally produced by a battery will explode
if a flame or spark is brought near. Use only
standardized jumper cables and do not smoke or
light a match while jump starting.
