This light warns that the battery is being discharged.
If it comes on while you are driving, stop the vehicle, turn
off the engine, and check for the cause. Look first at the
engine drive belt.
If it is loose or broken, the generator will not charge
the battery properly.
 If the belt is O.K., there is a problem somewhere in the
charging system.
The engine ignition will continue to operate, however,
until the battery is discharged. Turn off the air
conditioning, blower, radio, etc., and drive directly to the
nearest Lexus dealer or repair shop.

assistance.
The light may occasionally flicker when the engine is
idling or it may come on briefly after a hard stop. There
is no cause for concern if it then goes out when the
engine is accelerated slightly.
The light may come on when the oil level is extremely
low. It is not designed to indicate low oil level, and the
oil level must be checked using the oil level dipstick.

COMFORT ADJUSTMENT

The indicator comes 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, front airbag sensors, inflators, seat
belt pretensioners, warning light, interconnecting wiring
and power sources. (For details, see ºService reminder
indicators and warning buzzersº on page 56 for

6SRS warning light
7Airbag sensor assembly
8Front airbag sensor
The SRS airbag sensor assemblies consist of a safing
sensor and driver and front passenger airbag sensor. In a severe frontal impact, the driver and front passenger
airbag sensor detects deceleration and the system
triggers the front airbag inflators and seat belt
pretensioners. In a severe side impact, the side airbag
sensor
triggers the side airbag inflator. Then a chemical
reaction in the inflators momentarily fills the airbags with
non±toxic gas to help restrain the forward or lateral
motion of the occupants. Then the inflators fill the
airbags and the seat belts are quickly drawn back in by
the retractors to help restrain forward motion of the
occupants.
When the SRS operates, it produces a fairly loud noise
and release some smoke and residue along with
non±toxic gas. This does not indicate a fire. This gas is
normally harmless, however, for those who have
delicate skin, it may cause minor skin irritation. Be sure
to wash off any residue as soon as possible to prevent
minor skin irritation.
