STEERING WHEEL AND MIRRORS
180
TILT STEERING COLUMN
SV16064
To change the steering wheel angle, hold the steering
wheel, pull the lock release lever toward you, tilt the
steering wheel to the desired angle and release the lever.
When the steering wheel is in a low position, it will spring up as
you release the lock release lever.
CAUTION
 Do not adjust the steering wheel while the vehicle is
moving. Doing so may cause the driver to mishandle
the vehicle and an accident may occur resulting in
death or injuries.
 After adjusting the steering wheel, try moving it up
and down to make sure it is locked in position.
OUTSIDE REAR VIEW MIRRORS
SV16010
Adjust the mirror so that you can just see the side of your
vehicle in the mirror.
Be careful when judging the size or distance of any object seen
in the outside rear view mirror on the passenger's side
because it is a convex mirror. Any object seen in a convex
mirror will look smaller and farther away than if seen in a normal
flat mirror.
When you push the rear window and outside rear view mirror
defogger switch or operate the wipers, the heater panels in the
outside rear view mirrors will quickly clear the mirror surface.
(See ª Rear window and outside rear view mirror defogger, and
windshield wiper deicer switchº on page 36.)
Some models: When the inside rear view mirror darkens in
ªAUTOº mode, the outside rear view mirrors also darken to
reduce the reflection of the headlights of the following vehicle.
For details, see ªInside rear view mirrorº on page 182.

VEHICLE STABILITY CONTROLSYSTEM
The vehicle stability control system helps provide
comprehensive control of the systems such as anti±lock
brake system, traction control, engine control, etc. This
system automatically controls the brakes and engine to
help prevent the vehicle from skidding when cornering on
a slippery road surface or operating steering wheel
abruptly.
This system 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 just after the vehicle begins to move. This means that
the system is in the self±check mode, but does not indicate a
malfunction.
CAUTION
 Do not rely excessively on the vehicle stability
control system. Even if the vehicle stability control
system is operating, you must always drive carefully
and attentively to avoid serious injury. Reckless
driving will result in an unexpected accident. If the
slip indicator light blinks, sounding an alarm, special
care should be taken while driving.
 Only use tires of specified size. The size,
manufacture, 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
stability control system may not function correctly.
When replacing the tires or wheels, contact your
Lexus dealer.
 In situations where the road surface is covered with
ice or snow, your vehicle should be fitted with snow
tires or tire chains.

STARTING AND DRIVING
262
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 tire 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 a 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 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.

BRAKE PAD WEAR INDICATORS
SS31030
The brake pad wear limit indicators on your disc brakes
give a warning noise when the brake pads are worn to the
extent that replacement is required.
If you hear a squealing or scraping noise while driving, have
the brake pads checked and replaced by your nearest Lexus
dealer immediately.
Avoid continuous driving with the warning noise.
Continuous driving without replacing the brake pads will cause
expensive rotor damage and increasing brake pedal effort to
get the same stopping distance.
LIMITED±SLIP DIFFERENTIAL
Some vehicles are equipped with a limited±slip differential. If
one rear wheel begins to spin, the limited±slip differential is
designed to aid traction by automatically transmitting driving
force to the other rear wheel. If you are not sure whether your
vehicle is equipped with one, you can ask your Lexus dealer.
CAUTION
Do not start or run the engine while your vehicle is
supported by a jack. The vehicle could be driven off the
jack and could pose a danger or result in serious injury.
NOTICE
Use only a spare tire of the same size, construction and
load capacity as the original tires on your Lexusbecause damage to the limited±slip differential couldpossibly occur with another tire type.
