OUTSIDE REAR VIEW MIRRORS
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 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 103. 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 39.)
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.
 Since the mirror surfaces can get hot, do not touch
them when the rear window and outside rear view
mirror defogger switch is on.

COMFORT ADJUSTMENT
103
INSIDE REAR VIEW MIRROR
Adjust the mirror so that you can just see the rear of your
vehicle in the mirror.
Pushing the “MIRROR” switch 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 ignition key is inserted and turned on, the inside rear
view mirror always turns on in the AUTO 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.
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.
To ensure correct functioning of an antiglare mirror
sensor located on the back side of the mirror, do not touch
or cover the sensor with your finger or a piece of cloth, etc.

THEFT DETERRENT
156
THEFT DETERRENT SYSTEM
To deter theft of the vehicle, this system is designed to
sound an alarm if any of the doors, trunk or hood is
forcibly unlocked or the battery terminal is disconnected
and then reconnected while the vehicle is locked.
The alarm blows the horn intermittently and flashes the
headlights, tail lights and turn signal lights.
Further more when the interior light switch is in the “DOOR”
position, the interior light turns on.
After the alarm is activated, when you unlock any door using
an ignition key or wireless remote control, the tail lights turn on
for about 2 seconds to inform you that the system was
activated.
 Security indicator light
Setting the system
1. Turn the ignition key to the “LOCK” position and
remove it.
The engine immobiliser system causes the indicator light to
flash.
2. Close and lock all the doors, trunk and hood using an
ignition key or wireless remote control.
If you lock them with wireless remote control, the turn signal
lights flash once.
The flashing indicator light will remain on when all the doors,
trunk and hood are closed and locked.
3. After 30 seconds, the indicator starts flashing and the
system is set.

CHECKING THE CARTRIDGE TYPEFUSES
Engine compartment
Driver’s side instrument panel
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.

number of turns and in the same direction at step 1 using a
Phillips−head screwdriver.
REPLACING LIGHT BULBS
The illustration 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.
CAUTION
 To prevent burning yourself, do not replace the light
bulbs while they are hot.
 Vehicles with discharge headlight—Do not
disassemble, repair or take apart the low beam
headlight bulbs, connector, power supply circuits
and rotated components. Or you may be injured by
electric shocks. Call your dealer when the headlights
fail to work or have to be replaced or disposed of.
 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.
NOTICE
Only use a bulb of the listed type.

ELECTRICAL COMPONENTS

The inside of the lens of exterior lights such as headlights may
temporarily
fog up when the lens becomes wet in the rain or in
a car wash. This is not a problem because the fogging is
caused by the temperature dif ference between the outside and
inside of the lens, just like the windshield fogged up in the rain.
However, if there is a large drop of water on the inside of the
lens, or if there is water pooled inside the light, contact your
Lexus dealer. LIGHT LOCATION
