GAUGES, METERS AND SERVICE REMINDER INDICATORS
58Any of the following conditions may occur, but do not
indicate the malfunction:
The light may stay on for about 60 seconds after the ignition
key is turned to the ONº position. It is normal if it turns off
after a while.
Depressing the brake pedal repeatedly may turn on the
warning light and buzzer. It is normal if the light turns off and
the buzzer stops sounding after a few seconds.
You may hear a small sound in the engine compartment
after the engine is started or the brake pedal is depressed
repeatedly. This is a pump pulsating sound of the brake
system, and it is not a malfunction.
(b) Driver's Seat Belt Reminder Light and Buzzer
This light and buzzer remind you to buckle up the driver's seat
belt.
Once the ignition key is turned to ONº or STARTº, 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 Belt Reminder Light
This light reminds you to buckle up the front passenger's seat
belt.
Once the ignition key is turned to ONº or STARTº, 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 or other 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.

sensor assemblies, curtain shield airbag sensor assemblies,
driver's seat position sensor, driver's seat belt buckle switch,
front seat belt pretensioner assemblies, inflators, warning light,

light system. Contact your Lexus dealer as soon as possible
to service the vehicle.
When the ignition key is turned to the ONº position, the light
does not come on, remains on or flashes.
The light comes on or starts flashing while driving.

passenger airbags have a problem. If the light flashes, the side
and curtain shield airbags and/or seat belt pretensioners have
a problem.

OCCUPANT RESTRAINT SYSTEMS
145
CAUTION
After inserting the tab, make sure the tab and buckle
are locked and that the lap and shoulder portions of
the belt and the seat belt extender are not twisted.
Do not insert coins, clips, etc. in the buckle as this
may prevent you from properly latching the tab and
buckle.
If the seat belt does not function normally,
immediately contact your Lexus dealer. Do not use
the seat until the seat belt is fixed, because it cannot
protect an adult occupant or your child from injury.
Seat belt pretensioners
The driver and front passenger's seat belt pretensioners
are designed to be activated in response to a severe
frontal impact.
When the sensor detects a severe frontal impact, the front seat
belts are quickly drawn back by the retractors so that the belts
snugly restrain the front seat occupants.
The front seat belt pretensioners are activated even if there is
no passenger sitting in the front seat.
The seat belt pretensioners and SRS airbags may not operate
together in case of collisions at a certain speeds and angles.

1Front airbag sensors
2Seat belt pretensioner assemblies
3SRS warning light
4Airbag sensor assembly
The front seat belt pretensioner system consists mainly of the
above components, and their locations are shown in the
illustration.
The front seat belt pretensioners are controlled by the airbag
sensor assembly. The airbag sensor assembly consists of a
safing sensor and airbag sensor.
When the front seat belt pretensioners are activated, an
operating noise may be heard and a small amount of non-toxic
gas may be released. This does not indicate that a fire is
occurring. This gas is normally harmless.
Once the front seat belt pretensioners have been activated, the
seat belt retractors remain locked.
CAUTION
Do not modify, remove, strike or open the front seat belt
pretensioner assemblies, airbag sensor or surrounding
area or wiring. Failure to follow these instruction may
prevent the seat belt pretensioners from activating
correctly, cause sudden operation of the system or
disable the system, which could result in death or
serious injury. Consult your Lexus dealer about any
repairs and modifications.
