2002 Lexus IS300 steering

STARTING AND DRIVING
224When starting the engine, the key may seem stuck at the
ºLOCKº position. To free it, first be sure the key is pushed all
the way in, and then rock the steering wheel slightly while
turning the key gently.
If, in an emergency, you must turn the engine off while the
vehicle is moving, turn the key only to ºACCº.
CAUTION
For manual transmission:
Never remove the key when the vehicle is moving, as
this will lock the steering wheel and result in loss of
steering control.
PARKING BRAKE
SV31017
To set: Pull up the lever. For better holding power, first
depress the brake pedal and hold it while setting the
parking brake.
To release: Pull up the lever slightly (1) , press the lock
release button (2), and lower (3).
To remind you that the parking brake is set, the parking brake
reminder light in the instrument panel remains on until you
release the parking brake.
CAUTION
Before driving, make sure the parking brake is fully
released
and that the parking brake reminder light is off.

5. Release the parking brake and brake pedal. Depress
the accelerator pedal slowly for smooth starting.
In normal cruising, the vehicle will start in the first gear and
automatically shift up to the most suitable gear. On inclines,
declines or winding roads, etc., the vehicle shifts up and down
automatically
according to the running conditions to obtain the
suitable driving power and engine braking.
When the lever is in º3º position, the automatic transmission
system will select the most suitable gear for the running
conditions such as hill climbing, hard towing, etc.
If you need to accelerate rapidly while driving, depress the
accelerator pedal to the full throttle position. This provides
more acceleration by automatically downshifting the
transmission to the next lower gear or beyond, depending on
the vehicle speed.
If engine braking is needed, such as in descending a long hill,
see º(b) Using engine brakingº.
(b) Driving in M mode
If the change lever is shifted to M position, the shift range
position can be switched over between 5 and 2 using the
shift switch on the steering wheel instead of operating the
change lever. The first shift range position is on 5 when
the change lever is shifted to M position.

2Downshifting on the front, Upshifting on the rear
5: Fifth rangeThe most suitable gear is selected automatically
between first and fifth gears according to the vehicle
speed or the running condition.
4: Fourth range The most suitable gear is selected automatically
between first and fourth gears according to the vehicle
speed or the running condition. 3: Third range
The most suitable gear is selected automatically
between first and third gears according to the vehicle
speed or the running condition.
Slight engine braking will be obtained on a downhill
road.
Smooth running with less shifting will be obtained on an
uphill.
2: Second range First or second gear will be selected automatically
according to the vehicle speed or the running condition.
This range is used in the case that the engine braking is
necessary.
The gear position being used is shown on the instrument
cluster.
Each time you push the switch located on the front of the
steering wheel, the transmission downshifts (from º5º) to º4º\
,
º3º and then º2º.
When you push the switch located on the back of the steering
wheel, the transmission upshifts to º3º, º4º and then º5º\
.
For the precautions on each position, see the description on
the next page.

STARTING AND DRIVING

Warning tone sounds twice in any of the following cases:

You attempt to downshift the transmission when it is not
possible to downshift due to the high vehicle speed.
 You attempt to downshift from º2º position.
 You attempt to upshift from º5º position.
If the ºMº indicator flashes, there is a problem somewhere
in the system. In this case, it should be noted that you
cannot downshift or upshift the transmission using the
switches on the steering wheel. Consult with your Lexus
dealer as soon as possible. The transmission works
exactly in the same way as when you put the selector lever
in the ºDº position.
CAUTION
Be careful when downshifting on a slippery surface.
The abrupt change in engine speed could cause the
vehicle to spin or skid.
(c) Using engine braking
SV31023
To use the braking power of the engine, downshift the
transmission in the way described below:
1Shift into the ºMº position, and you push the transmission
down shift switch. The transmission will downshift to
fourth gear and engine braking will be obtained. This is
effective only when you are driving in the ºDº position or
in fifth gear (ºMº position).
When the cruise control is being used, even if you
downshift from º5º to º4º, engine braking will not be
enabled because the cruise control is not cancelled. If
you need to decrease the vehicle speed, see page 239.
2Shift into the º3º position. The transmission will downshift
to third gear when the vehicle speed is or becomes lower
than the speed listed below and stronger engine braking
will be obtained.

VEHICLE SKID CONTROL SYSTEM
The vehicle skid control system helps provide integrated
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.
SV31037

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.
When
you turn the ignition switch on, this system always turns
on.

STARTING AND DRIVING
247
Anti±lock brake system
The anti±lock brake system is designed to automatically
help prevent lock±up of the wheels during a sudden
braking or braking on slippery road surfaces. This assists
in providing directional stability and steering
performance of the vehicle under these circumstances.
Effective way to press the ABS brake pedal: When the
anti±lock brake system function is in action, you may feel the
brake pedal pulsating and hear a noise. In this situation, to
let the anti±lock brake system work for you, just hold the
brake pedal down more firmly. Do not pump the brake in a
panic stop. This will result in reduced braking performance.
The 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.
CAUTION
Do not overestimate the anti±lock brake system:
Although the anti±lock brake system assists in
providing vehicle control, it is still important to drive
with all due care and maintain a moderate speed and
safe distance from the vehicle in front of you, because
there are limits to the vehicle stability and effectiveness
of steering wheel operation even with the anti±lock
brake system on.
If tires grip performance exceeds its capability, or if
hydroplaning occurs during high speed driving in the
rain, the anti±lock brake system does not provide
vehicle control.
Anti±lock brake system is not designed to shorten the
stopping distance: Always drive at the moderate speed
and maintain a safe distance from the vehicle in front of
you. Compared with vehicles without an anti±lock
brake system, your vehicle may require a longer
stopping distance in the following cases:

DRIVING TIPS
257
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.

DRIVING TIPS
260

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 ºOwner's Manual
Supplement / Scheduled Maintenanceº.)
CAUTION
Never turn off the engine to coast down hills. Your
power steering and brake booster will not function
without the engine running. Also, the emission control
system operates properly only when the engine is
running.
