KEYS
Vehicles with power back door system
Vehicles without power back door system
1Master keys (black) — These keys work in every lock.
For your Lexus dealer to make a new key with a
builtin transponder chip, your dealer will need one
of them.
2Valet key (gray) — This key will not open the glove
box.
3Key number plate — Keep the plate in a safe place
such as your wallet, not in the vehicle.
A transponder chip for the engine immobilizer system has been
placed in the head of the master and valet keys. These chips
are required for the system to function correctly, so be careful
not to lose these keys. If you make your own duplicate key, you
will not be able to cancel the system or start the engine.
To protect items locked in the glove box when using valet
parking, leave the valet key with the attendant.
Since the side doors and back door can be locked without a
key, you should always carry a spare master key in case you
accidentally lock your keys inside the vehicle.
If you should lose your keys or if you need additional keys,
duplicates can be made by a Lexus dealer using the key
number.
We recommend writing down the key number and storing it in
a safe place.

KEYS AND DOORS

Flat key
As a transponder chip is built in its key case, you can start
the engine with this key.
The flat key works in every lock.
A transponder chip for engine immobilizer system has been
placed in the key case of the flat key. This chip is needed to
enable the system to function correctly, so be careful not to lose
this key. If you make your own duplicate key, you will not be
able to cancel the system or start the engine.
Insert your flat key plate in its key case as shown. We
recommend that you always carry this with you for emergency
use. Do not leave it in your vehicle.
Starting the engine using a flat key
1. Remove the key plate from the key case.
2. Insert the key plate into the ignition switch. The indicator
light keeps flashing.
3. Bring the key case closer to the ignition switch within 10
seconds as indicated by the arrow head. The indicator light
goes out. This means the engine immobilizer system is
automatically canceled. (For details, see “Engine immobilizer
system” on page 16.) You can put the key case away then. You
cannot cancel the engine immobilizer system if 10 seconds
have past after you inserted the key plate. You need to remove
the key plate from the ignition switch and try it again from the
step 2.

KEYS AND DOORS
144. Start the engine within 60 seconds after the security
indicator light goes out. You cannot start the engine if 60
seconds have past after the security indicator went off. You
need to remove the key plate from the ignition switch and try
it again from the step 2.
NOTICE

Do not let the key case become bent as the key plate
may fall out or become bent also.
 The flat key is designed for emergency use only. So
do not use it regularly instead of other master keys.
When using a key containing a transponder chip,
observe the following precautions:
When starting the engine, do not use the key with a
key ring resting on the key grip and do not press the
key ring against the key grip. Doing so may prevent
the engine from starting, or may cause the engine to
stop soon after it starts.

KEYS AND DOORS
15
When starting the engine, do not use the key in
proximity with other transponder keys (including the
flat key and keys of other vehicles), and do not press
other key plates against the key grip. Doing so may
prevent the engine from starting, or may cause the
engine to stop soon after it starts. If this happens,
remove the key once and then insert it again after
removing other transponder keys (including the flat
key and keys of other vehicles) from the ring or while
gripping or covering them with your hand to start the
engine. Do not bend the key grip or flat key.
 Do not cover the key grip or flat key with any material
that cuts off electromagnetic waves.
 Do not knock the key or flat key hard against other
objects.
 Do not leave the key or flat key exposed to high
temperatures for a long period, such as on the
dashboard or hood under direct sunlight.
 Do not put the key or flat key in water or wash it in an
ultrasonic washer.
 Do not use the key or flat key with electromagnetic
materials.

ENGINE IMMOBILIZER SYSTEM
The engine immobilizer system is a theft prevention
system. When you insert the key in the ignition switch, the
transponder chip in the key’s head transmits an electronic
code to the vehicle. The engine will start only when the
electronic code in the chip corresponds to the registered
ID code for the vehicle.
The system is automatically set when the key is removed from
the ignition switch. At this time, the security indicator light
flashes. When you insert the key in the ignition switch, the
security indicator light goes out and the system is canceled
automatically, which enables the engine to start. The transponder chip of the flat key is in its key case. You can
cancel the engine immobilizer system using the flat key. (For
details, see “Flat key” on page 13.)
For your Lexus dealer to make you a new key with built
−in
transponder chip, your dealer will need your key number and
master key or the flat key. However, there is a limit to the
number of additional keys your Lexus dealer can make for you.
If you make your own duplicate key, you will not be able to
cancel the system or start the engine.

THEFT DETERRENT SYSTEM
To deter theft of the vehicle, this system is designed to
sound an alarm if any of the doors 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.
 Security indicator light
Setting the system
1. Turn the ignition key to the “LOCK” position and
remove it.
The engine immobilizer system causes the indicator light to
flash.
2. Close and lock all the doors and hood using an ignition
key or wireless remote control.
The flashing indicator light will remain on when all the doors
and hood are closed and locked.
3. After 30 seconds, the indicator starts flashing and the
system is set.

SWITCHES
49
The automatic light control sensor is on the top of the driver’s
side instrument panel.
Do not place anything on the instrument panel, and/or do not
affix anything on the windshield to block this sensor.
When the headlights come on: The lights automatically turn off
about 30 seconds after any of the side doors and back door is
opened and closed with the ignition key turned to the “ACC” or
“LOCK” position. Additionally, the lights can be turned off
immediately by pushing the “LOCK” button on the wireless
remote control key with all the side doors and back door locked. When
only the tail lights come on: The lights automatically turn
off with the driver’s door opened and the ignition key turned to
the “ACC” or “LOCK” position. To turn them on again, turn the
ignition key to the “ON” position, or turn the headlight switch off
and then twist the knob until the first or second clickstop.
If you are going to park for over one week, make sure the
headlight switch is off.
Daytime Running Light System
The headlights turn on at reduced intensity when the parking
brake is released with the engine started, even with the light
switch in the “OFF” position. They will not go off until the
ignition switch is turned off.
To turn on the other exterior lights and instrument panel lights,
twist the knob to the first clickstop.

SWITCHES
50Twist
the knob to the second clickstop to turn on the headlights
to full intensity for driving at night.
When setting the knob to the third clickstop (“AUTO”), the
headlights will automatically adjust to full intensity and/or turn
on the other lights depending on the darkness of the
surroundings. Likewise, as the surroundings become brighter,
the headlights will turn to reduced intensity, ultimately turning
off the other lights.
NOTICE
To prevent the battery from being discharged, do not
leave the lights on longer than necessary when the
engine is not running.
Automatic headlight leveling system
(vehicles with discharge headlight only)
Vehicle position changes according to loading condition,
passengers getting on and off, vehicle acceleration and
deceleration, etc. However, the headlight beam level is always
maintained automatically by the system at the proper level so
that your headlights do not dazzle other road users.
If this system fails, the warning light in the instrument cluster
comes on. If this occurs, have your vehicle checked by your
Lexus dealer.
If you replace the rear suspension, contact your Lexus dealer
to check the automatic headlight leveling system and headlight
beam level.
