2003 Lexus IS300 lock

STARTING AND DRIVING
252ºABSº warning light
SV31014

U.S.A.
SV31031

CANADA
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.

STARTING AND DRIVING
253
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).For an explanation of this system's warning light, see ºABS
warning lightº on page 50 and ºVehicle skid control system
failure warningº on page 248.

DRIVING TIPS
259
TIPS FOR DRIVING IN VARIOUSCONDITIONS

Always slow down in gusty crosswinds. This will allow you
much better control.

Drive slowly onto curbs and, if possible, at a right angle.
Avoid driving onto high, sharp±edged objects and other
road hazards. Failure to do so can lead to severe tire
damage resulting in tire bursts.
Drive slowly when passing over bumps or travelling on a
bumpy road. Otherwise, the impact could cause severe
damage to the tires and/or wheels.

When parking on a hill, turn the front wheels until they touch
the curb so that the vehicle will not roll. Apply the parking
brake, and place the transmission in ºPº (automatic) or in
first or reverse (manual). If necessary, block the wheels.

Washing your vehicle or driving through deep water may get
the brakes wet. To see whether they are wet, check that
there is no traffic near you and then press the pedal lightly.
If you do not feel a normal braking force, the brakes are
probably wet. To dry them, drive the vehicle cautiously while
lightly pressing the brake pedal with the parking brake
applied. If they still do not work safely, pull to the side of the
road and call a Lexus dealer for assistance.
CAUTION

Before driving off, make sure the parking brake is
fully released and that the parking brake reminder
light is off.

Do not leave your vehicle unattended while the
engine is running.

Do not rest your foot on the brake pedal while driving.
It can cause dangerous overheating, needless wear,
and poor fuel economy.

To drive down a long or steep hill, reduce your speed
and downshift. Remember, if you ride the brakes
excessively, they may overheat and not work
properly. See page 235.

Be careful when accelerating, upshifting,
downshifting or braking on a slippery surface. The
abrupt change in engine speed, such as sudden
acceleration or engine braking, could cause the
vehicle to spin or skid.

Do not drive in excess of the speed limit. Even if the
legal speed limit permits it, do not drive over 140 km/h
(85 mph) unless your vehicle has high±speed
capability tires. Driving over 140 km/h (85 mph) may
result in tire failure, loss of control and possible
injury. Be sure to consult a tire dealer to determine
whether the tires on your vehicle are high±speed
capability tires or not before driving at such speeds.

DRIVING TIPS
261
Check the electronic ignition system for loose
connections or obvious damage.
Keep the door locks from freezing.
Squirt
lock de±icer or glycerine into the locks to keep them from
freezing.
Use a washer fluid containing an antifreeze solution.
This product is available at your Lexus dealer and most auto
parts stores. Follow the manufacturer's directions for how
much to mix with water.
NOTICE
Do not use engine antifreeze or any other substitute because it may damage your vehicle's paint.
Do not use your parking brake when there is a possibility
it could freeze.
When parking, put the transmission into ºPº (automatic) or into
first or reverse (manual) and block the front wheels. Do not use
the parking brake, or snow or water accumulated in and around
the parking brake mechanism may freeze the parking brake,
making it hard to release.
Keep ice and snow from accumulating under the fenders.
Ice and snow built up under your fenders can make steering
difficult. During bad winter driving, stop and check under the
fenders occasionally. Depending on where you are driving, we recommend you
carry some emergency equipment.
Some of
the things you might put in the vehicle are tire chains,
window scraper, bag of sand or salt, flares, small shovel,
jumper cables, etc.

IN CASE OF AN EMERGENCY
266
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.

5. Read the following instructions thoroughly.
CAUTION
When jacking, be sure to observe the following to
reduce the possibility of personal injury:
 Follow jacking instructions.
 Do not put any part of your body under a vehicle
supported by a jack. Personal injury may occur.
 Do not start or run the engine while your vehicle is
supported by the jack.
Stop the vehicle on a level firm ground, firmly set the
parking brake and put the transmission in ºPº
(automatic) or reverse (manual). Block the wheel
diagonally opposite to the one being changed if
necessary.
 Make sure to set the jack properly in the jack point.
Raising the vehicle with jack improperly positioned
will damage the vehicle or may allow the vehicle to fall
off the jack and cause personal injury.
 Never get under the vehicle when the vehicle is
supported by the jack alone.
 Use the jack only for lifting your vehicle during wheel
changing.
 Do not raise the vehicle with someone in the vehicle.
 When raising the vehicle, do not put an object on or

2. Block the wheel diagonally opposite the flat tire to keep
the vehicle from rolling when it is jacked up.
When blocking the wheel, place a wheel block in front of one
of the front wheels or behind one of the rear wheels.
SS41008
3. Loosen all the wheel nuts.
Always loosen the wheel nuts before raising the vehicle.
Turn the wheel nuts counterclockwise to loosen them. To get
maximum leverage, fit the wrench to the nut so that the handle
is on the right side, as shown above. Grab the wrench near the
end of the handle and pull up on the handle. Be careful that the
wrench does not slip off the nut.
Do not remove the nuts yet ± just unscrew them about one±half
turn.
CAUTION
Never use oil or grease on the bolts or nuts. The nuts
may loosen and the wheels may fall off, which could
cause a serious accident.
