STEERING WHEEL AND MIRRORS
180
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. 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 º 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
ºAUTOº mode, the outside rear view mirrors also darken to
reduce the reflection of the headlights of the following vehicle.
For details, see ºInside rear view mirrorº on page 182.

INSIDE REAR VIEW MIRROR
SL16013

Type A 1Day 2Night
When driving at night, pull the lever toward you to reduce
the glare from the headlights of vehicles behind you.
Before adjusting the mirror to the position with most clarity,
push the day-night change lever forward (daylight driving
position).
Remember that by reducing glare you also lose some rear view
clarity.
CAUTION
Do not adjust the mirror while the vehicle is moving.
Doing so may cause the driver to mishandle the vehicle
and an accident may occur resulting in personal death
or injuries.
SV16128

Type B
Adjust the m irror so that you can just see the rear of your
vehicle in the mirror.
Pushing the switch changes the mode between ºAUTOº
and ºDAYº.
The indicator comes on when the ºAUTOº mode is selected.
ºDAYº mode: The mirror surface is normal.
ºAUTOº mode: If the mirror detects light from the
headlights of the vehicle behind you, the mirror surface
darkens slightly to reduce the reflected light.
When the inside rear view mirror surface changes, the outside
rear view mirror surfaces will also become darker.
When the ignition key is inserted and turned on, the inside rear
view mirror always turns on in the ºAUTOº mode.
When the outside air temperature is low, it may take a little
longer for the mirror to darken in response to the detection of
headlights.

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 a damaged wheel, 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.
CAUTION
Observe the following instructions. Otherwise, an
accident may occur resulting in death or serious
injuries.
Do not use wheels other than the manufacturer's
recommended size, as this may cause dangerous
handling characteristics resulting in loss of control.
