SWITCHES
37
The automatic light control sensor is on 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 doors is
opened and closed with the ignition key turned to the
ºACCº or ºL
OCKº 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,
pushing the ºLOCKº button on the wireless remote
control key turns off the headlights.
NOTE: *The operating condition or sensitivity can be changed. **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 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 necessarywhen the engine is not running.

(a) Brake System Warning Light
This light has the following two functions:
Parking brake reminder
If this light is on, make sure the parking brake is fully
released. The light should go off.
Low brake fluid level warning
If this light comes on and stays on while you are driving,
slow down and pull off the road. Then stop the vehicle
carefully. Remember that stopping distance and pedal
effort may be increased. There may be a problem
somewhere in the brake system. Check the fluid level
of the see±through reservoir.
To make sure the parking brake has not caused the
warning light to come on, check to see that the parking
brake is fully released.
If the brake fluid level is low ...
At a safe place, test your brakes by starting and
stopping.
If you judge that the brakes still work adequately, drive
cautiously to your nearest dealer or shop for repairs.
 If the brakes are not working, have the vehicle towed
in for repairs. (For towing information, see page 366.)

(b) Driver's Seat Belt Reminder Light
and Buzzer
Once the ignition key is turned to ºONº or ºSTARTº, the
reminder light flashes and buzzer sounds if the driver's
seat belt is not fastened. Unless the driver fastens the
belt, the light stays flashing and the buzzer stops after
about 4 to 8 seconds.
(c) Front Passenger's Seat BeltReminder Light
Once the ignition key is turned to ºONº or ºSTARTº, the
reminder light flashes if a passenger sits in the front
passenger seat and does not fasten the seat belt.
Unless the front passenger fastens the belt, the light
stays flashing.
If luggage load is placed on the front passenger seat,
depending on its weight and how it is placed on the seat,
built±in sensors in the seat cushion may detect the
pressure, causing the reminder light to come on.
(d) SRS Warning Light
The indicators come on when the ignition key is
turned to the ºACCº or ºONº position. It goes off
after about 6 seconds. This means the SRS is
operating properly.
The SRS warning light system monitors the airbag
sensor assemblies, inflators, seat belt pretensioners,
warning light, interconnecting wiring and power sources.
If either of the following conditions occurs, this indicates
a malfunction somewhere in the parts monitored by the
warning light system. Contact your Lexus dealer as
soon as possible to service the vehicle.
 The light does not come on as described above.
 The light stays on or flashes.
 The light comes on or starts flashing while driving.
If the light stays on, it indicates that the driver and front
passenger airbags fail. If the light flashes, the side
airbags and/or seat belt pretensioners fail.
