STARTING AND DRIVING
184When getting the vehicle out of mud or new snow, etc. the
traction control system will help operate to prevent the wheels
from spinning.
CAUTION
Under certain slippery road conditions, full traction of
the vehicle and power to the rear 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.
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!
CAUTION
Do not pump the brake pedal if the engine stalls.
Each push on the pedal uses up your reserved
vacuum.
 Even if the power assist is completely lost, the brakes
will still work.  But you will have to push the pedal
hard, much harder than normal.  And your braking
distance will be longer.

STARTING AND DRIVING
186
Driving on rough, gravel or snow±covered roads.
 Driving with tire chains installed.
 Driving  over the steps such as the joints on the road.
 Driving on roads where the road surface is pitted or
has other differences in surface height.
Install all 4 tires of specified size at appropriate
pressure:  The anti±lock brake system detects vehicle
speeds using the  speed sensors for respective wheels'
turning speeds.  The use of tires other than specified
may fail to detect the accurate turning speed resulting
in a longer stopping distance.ºABSº warning light

The light comes on when the ignition key is turned to the ºONº
position. If the anti±lock brake system works properly, the light
turns off after a few seconds. Thereafter, if the system
malfunctions, the light comes on again.

STARTING AND DRIVING
187
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, 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.

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.
Warning: Battery posts, terminals and related
accessories contain lead and lead compounds,
chemicals known to the State of California to cause

Chain installation
Install the chains on the rear tires as tightly as possible.
Do not use tire chains on the front tires.  Retighten chains
after driving 0.5 ± 1.0 km (1/4 ± 1/2 mile).
When installing chains on your tires, carefully follow the
instructions of the chain manufacturer.
CAUTION
Do not exceed 50 km/h (30 mph) or the chain
manufacturer's recommended speed limit,
whichever is lower.
 Drive carefully avoiding bumps, holes, and sharp
turns, which may cause the vehicle to bounce.
 Avoid  sharp turns or locked±wheel braking, as use of
chains may adversely affect vehicle handling.
 When driving with chains installed, be sure to drive
carefully.  slow down before entering the curves to
avoid losing control of the vehicle, it may cause an
accident.
REPLACING WHEELS
When to replace your wheels
If you have wheel damage such as bends, cracks or heavy
corrosion, the wheel should be replaced.
If you fail to replace damaged wheels, the tire may slip off the
wheel or cause loss of handling control.
Replacement with used wheels is not recommended as they
may have been subjected to rough treatment or high mileage
and could fail without warning.  Also, bent wheels which have
been straightened may have hidden structural damage and
therefore should not be used.  Never use an inner tube in a
leaking wheel which is designed for a tubeless tire.
Wheel selection
When replacing wheels, care should be taken to ensure
that they are equivalent to those removed in load capacity,
diameter, rim width, and offset.
Correct replacement wheels are available at your Lexus
dealer.
A wheel of a different size or type may adversely affect
handling, wheel and bearing life, brake cooling,
speedometer/odometer calibration, stopping ability, headlight
aim,  bumper height, vehicle ground clearance, and tire or snow
chain clearance to the body and chassis.
