SWITCHES
55
HEADLIGHT CLEANER SWITCH
The headlight cleaner switch is located in the switch box.
G12010
Push the button to use the switch box. To spray fluid on
the headlights, push the switch with the headlights on.
The engine switch must be selected in “IG−ON” mode.
The warning message “LOW WASHER FLUID” is displayed in
the multi−information display when the fluid level in the tank
becomes very low. For information on adding washer fluid, see
“Adding washer fluid” on page 579.
After operation, be sure to close the switch box to its original
position.
CAUTION
To reduce the chance of injury in case of an accident or
a sudden stop, keep the switch box closed when not in
use while driving.
NOTICE
Do not turn the headlight cleaner on with the washer
fluid tank empty. It may cause the cleaner motor to
overheat.

STEERING WHEEL AND MIRRORS
205
Automatic tilt away*
G17003
When the engine switch is off, the steering column moves
forward away from the driver and also tilts up for easy exit
and entry.
When you turn on the engine switch, the steering column
returns to the previously set position.
NOTE:
*This feature can be deactivated.
Ask your Lexus dealer for details.
OUTSIDE REAR VIEW MIRRORS
G17004
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 the inside rear view mirror darkens in ”AUTO” mode, the
outside rear view mirrors also darken to reduce the reflection
of the headlights of the following vehicle. For details, see
”Inside rear view mirror” on page 209.
When you push the rear window and outside rear view mirror
defogger switch, the heater panels in the outside rear view
mirrors will quickly clear the mirror surface. (See “Rear window
and outside rear view mirror defogger switch” on page 56.)

STEERING WHEEL AND MIRRORS
209
The outer foot lights go off 15 seconds after the lights come on
or when:

Pushing the lock switch on the outside door handle with an
electronic key in possession,
 the doors are locked with th e wireless remote control
function,
 the doors are locked by inserting a mechanical key into the
door keyhole,
 the doors are locked with the power door lock switch on the
driver’s side, or
 the selector lever is moved out of “P” position when the
engine switch is on.
NOTE:
* The outer foot lights illuminating time can be changed.
Ask your Lexus dealer for details.
INSIDE REAR VIEW MIRROR
G17007
Adjust the mirror so that you can just see the rear of your
vehicle in the mirror.
Pushing the “AUTO” button changes the mode between
”AUTO” and ”DAY”.
The indicator comes on when the ”AUTO” mode is selected.
”DAY” mode: The mirror surface is normal.
”AUTO” 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 engine switch is selected in “IG −ON” mode, the
inside rear view mirror always turns on in the ”AUTO” mode.

STEERING WHEEL AND MIRRORS
210When the outside air temperature is low, it may take a little
longer for the mirror to darken in response to the detection of
headlights.
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 death or serious
injuries.
G17008
To ensure correct functioning of antiglare mirror sensors
located on both sides of the mirror, do not touch or cover
the sensors with your finger or a piece of cloth, etc.
Compass
G17009
The compass indicates the direction in which the vehicle
is heading. The illustration shown above indicates the
vehicle is heading north.

REAR VIEW MONITOR SYSTEM CAMERA
G31078
The rear view monitor system camera is located on the trunk
as shown in the illustration. The camera uses a special lens.
The distance of the image that appears on the screen differs
from the actual distance.
In the following cases, it may become difficult to see the images
on the screen, even when the system is functioning.

In the dark (for example, at night)
 When the temperature near the lens is extremely high or low
 When water droplets are adhering to the camera, or when
humidity is high (for example, when it rains)
 When foreign matter (for example, snow or mud) adheres
to the camera lens
 When the sun or the beam of headlights is shining directly
into the camera lens
31L357
Check surroundings for safety.
If a bright light (for example, sunlight reflected off the vehicle
body) is picked up by the camera, the smear effect* peculiar
to the camera may occur.
*: Smear effect — A phenomenon that occurs when a bright
light (for example, sunlight reflected off the vehicle body) is
picked up by the camera; when transmitted by the camera, the
light source appears to have a vertical streak above and below
it.

Good Blown
If the headlights or other electrical components do not
work and the blade type fuses are O.K., check the
cartridge type fuses. If any of the cartridge type fuses are
blown, they must be replaced.
If there is an overload in the circuits from the battery, the fuses
are designed to blow before the entire wiring harness is
damaged.
CAUTION
Always use a genuine Lexus fuse or equivalent for
replacement. Never install an ordinary wire even for
a temporary fix. This may cause extensive damage and
possibly a fire.
NOTICE
Before replacing the fuses, have the cause of electrical
overload determined and repaired by your Lexus dealer.

Turn the bolt B in either direction using a Phillips−head
screwdriver.
If you do not know or cannot find the original position, or if you
feel that there is a large deviation, take the vehicle to your
Lexus dealer to adjust the headlight aim.
REPLACING LIGHT BULBS
The illustrations on the following pages show the locations of
light bulbs. If it is necessary to replace a bulb, take your vehicle
to your Lexus dealer as soon as possible. Use bulbs with the
bulb numbers and wattage ratings given in the table.
The tail lights, stop lights, high mounted stoplight and rear side
marker light consist of a number of LEDs. If any LED burns out,
we recommend you take your vehicle to your Lexus dealer to
have the light inspected as soon as possible.
CAUTION
 To prevent burning yourself, do not replace the light
bulbs while they are hot.
 Halogen bulbs have pressurized gas inside and
require special handling. They can burst or shatter if
scratched or dropped. Hold a bulb only by its plastic
or metal case. Do not touch the glass part of a bulb
with bare hands.
 Do not touch the high voltage socket when the head-
lights turn on. 20000 V is momentarily generated and
may cause severe injury by electric shock.
 Do not disassemble, repair or take apart the headlight
bulbs, connector, power supply circuits and rotated
components. Or you may be injured by electric
shock. Call your dealer when the headlights fail to
work or have to be replaced or disposed of.
