FRONT SEATS
(MANUAL TYPE)
Front seat precautions
CAUTION
The side airbags are installed in the driver and front
passenger seats. Observe the following precautions.
 Do not lean over the front door when the vehicle is in
use. The side airbag inflates with considerable speed
and force; you may be killed or severely injured.
 Do not modify or replace the seats or the upholstery
of the seats with side airbags. Such changes may
disable the system, or cause the side airbags to
inflate accidentally, resulting in death or serious
injury. Consult your Lexus dealer if you insist on
modifications of this kind.
 Do not use accessories for the seats which cover the
parts where the side airbags inflate. Such
accessories may prevent the side airbags from
activating correctly, causing death or serious injury.
Seat adjustment precautions
Adjust the driver's seat so that the foot pedals, steering wheel
and instrument panel controls are within easy reach of the
driver.
CAUTION
Do not adjust the seat while the vehicle is moving as
the seat may unexpectedly move and cause the
driver to lose control of the vehicle.
 Be careful that the seat does not hit a passenger,
luggage or the rear seat.
 After adjusting the seat position, try sliding it forward
and backward to make sure it is locked in position.
 After adjusting the seatback, exert body pressure to
make sure it is locked in position.
 Do not put objects under the seats. The objects may
interfere with the seat±lock mechanism or
unexpectedly push up the seat position adjusting
lever; the seat may suddenly move, causing the
driver to lose control of the vehicle.
 While adjusting the seat, do not put your hands under
the seat or near the moving parts. You may catch and
injure your hands of fingers.

TILT STEERING WHEEL
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. It 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. It is a
convex mirror with a curved surface. Any object seen in a
convex m irror will look smaller and farther away than if seen in
a normal flat mirror.
When the ignition switch is turned ºONº, the heater panels in
the outside rear view mirrors will quickly clear the surface.
The outside rear view mirror heater will operate while the
ignition switch is ºONº.

SV16066
Do not attach a cup holder or any other device or
object on or around the door. When the side airbag
inflates, the cup holder or any other device or object
will be thrown with great force, or the side airbag may
not activate correctly, resulting in death or serious
injury. Likewise, the driver and front passenger
should not hold objects in their arms or on their
knees.
Do not use seat accessories which cover the parts
where the side airbags inflate. Such accessories may
prevent the side airbags from activating correctly,
causing death or serious injury.
 Do not modify or remove any wiring. Do not modify,
remove, strike or open any components, such as the
steering wheel pad, steering wheel, column cover,
front passenger airbag cover, front seats or airbag
sensor assembly. Doing so may cause sudden SRS
front airbag inflation or disable the system, which
could result in death or serious injury.
 Do not modify or replace the seats or the upholstery
of front seats with side airbags. Such changes may
disable the system or cause the side airbags to inflate
accidentally, resulting in death or serious injury.
Failure to follow these instructions can result in death
or serious injury. Consult your Lexus dealer if you insist
on modifications of this kind.

DRIVING TIPS
193
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.

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. 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 175.

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.

Do not continue normal driving when the brakes are
wet. If they are wet, your vehicle will require a longer
stopping distance, and it may pull to one side when
the brakes are applied. Also, the parking brake will
not hold the vehicle securely.

IN CASE OF AN EMERGENCY
206
Stop the vehicle on a level firm ground, firmly set the
parking brake and put the transmission in ºPº. 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
under the jack.
 Raise the vehicle only high enough to remove and
change the tire.
NOTICE
Do not continue driving with a deflated tire. Driving
even a short distance can damage a tire and wheelbeyond repair.
Spare tire with turning direction indicators
(Some models)
SV41014
The spare tire with turning direction indicators is of a
uni±directional type and is intended for use on the
passenger side of the vehicle.
Installing the wheel on the driver side of the vehicle will not
affect tire performance. If the spare tire is used on the driver
side of the vehicle, it should be used only temporarily and then
replaced with the correct one.
