ENGINE IMMOBILISER SYSTEM
11L037

KEYS AND DOORS
16The engine immobiliser 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.
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. 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.
For vehicles sold in U.S.A.

SWITCHES
38When the headlights come on, the lights automatically
turn off about 30 seconds after any of the doors is
opened and closed with the ignition key turned to the
ºACCº or ºLOCKº position.* To turn them on again, turn
the ignition key to the ºONº 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.
When the headlight switch is on with all the doors locked
and the trunk closed, pushing the ºLOCKº button on the
wireless remote control key turns off the headlights.
NOTE: *The time before turning off the lights can be changed. Ask your Lexus dealer for details.
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 ºOFFº 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.
Twist 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 (ºAUTOº),
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 be
come 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 necessarywhen the engine is not running.
Automatic headlight leveling system
(Vehicles with discharge headlight only)
As the headlight beam level is always maintained
automatically at the proper level in all loading conditions,
your headlights do not dazzle other road users.
If this system fails, the multi information display shows
a message ºHEADLIGHT LEVELINGº. If this occurs,
have your vehicle checked by Lexus dealer. See page
79 for additional information.

ENGINE COOLANT
TEMPERATURE GAUGE
13L002±2

Normal range
The gauge indicates the engine coolant temperature
when the ignition switch is on. The engine operating
temperature will vary with changes in weather and
engine load.
If the needle points to the red zone or higher, stop your
vehicle and allow the engine to cool.
Your vehicle may overheat during severe operating
conditions, such as:
 Driving up a long hill on a hot day.
 Reducing speed or stopping after high speed driving.
 Idling for a long period with the air conditioning on in stop±and±go traffic.
 Towing a trailer.
NOTICE
Do not remove the thermostat in the engine
cooling system as this may cause the engine to
overheat. The thermostat is designed to control the flow of coolant to keep thetemperature of the engine within the specifiedoperating range.
Do not continue driving with an overheatedengine. See ºIf your vehicle overheatsº onpage 356.

TACHOMETER
13L003±1
The tachometer indicates engine speed in
thousands of rpm (revolutions per minute). Use it
while driving to prevent engine overrevving.
Driving with the engine running too fast causes
excessive engine wear and poor fuel economy.
Remember, in most cases the slower the engine speed,
the greater the fuel economy.
NOTICE
Do not let the indicator needle get into the red
zone. This may cause severe engine damage.
