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.

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.

headlights, tail lights and turn signal lights.
Further more when the interior light switch is in the “DOOR”
position, the interior light turns on.

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.

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.
