2003 Lexus GS300 service indicator

Front seat belt pretensioners
16G132b
The driver and front passenger's seat belt pretensioners
are designed to be activated in response to a severe
frontal impact.
When the airbag sensor detects the shock of a severe frontal
impact, the front seat belts are quickly drawn back by the
retractor so that the belts snugly restrain the front seat
occupants.
The front passenger seat belt pretensioner will not activate if
there is no passenger sitting in the front passenger seat.
However, the front passenger seat belt pretensioner may
activate if luggage is put in the seat, or the seat belt is buckled
up regardless of the presence of the occupant in the seat.
Collisions occurring at certain speeds and angles may cause
the seat belt pretensioners and SRS airbags not to operate all
together.

This indicator comes on when the ignition key is turned to
the ªONº position. It goes off after about 6 seconds. This
means the front seat belt pretensioners are operating
properly.
This warning light system monitors the airbag sensor
assembly, front airbag sensors, side and curtain shield airbag
sensors, occupant detection sensor, seat belt buckle switch,
front seat belt pretensioner assemblies, inflators, warning light,
interconnecting wiring and power sources. (For details, see
ºService reminder indicators and warning buzzersº on page
40.)

Repairs made on or near the front fenders, front end
structure or console.

as soon as possible to service the vehicle.
When the ignition key is turned to the ªONº position, the light
does not come on or flashes.
The light flashes while driving.

In the following cases, contact your Lexus dealer as soon as
possible.
The front of the vehicle (shaded in the illustration) were
involved in an accident that did not cause the front seat belt
pretensioners to operate.
Either front seat belt pretensioner assembly or surrounding
area is scratched, cracked, or otherwise damaged.

Your vehicle is equipped with a crash sensing and diagnostic
module, which will record the use of the seat belt restraint
system by the driver when the curtain shield airbags are
inflated.
CAUTION
The curtain shield airbags inflate with considerable
force. To avoid potential death or serious injury when
they inflate, the driver and front passenger must:
Wear their seat belts properly.
Remain properly seated with their back upright and
against the seat at all times.

The indicator comes on when the ignition key is turned to
the ºONº position. It goes off after about 6 seconds. This
means the SRS airbags are operating properly.
This warning light system monitors the airbag sensor
assembly, front airbag sensors, side and curtain shield airbag
sensors, occupant detection sensor, seat belt buckle switch,
front seat belt pretensioner assemblies, inflators, warning light,
interconnecting wiring and power sources. (For details, see
ºService reminder indicators and warning buzzersº on page
40.)
The front airbags are designed to deploy in severe
(usually frontal) collisions where the magnitude and
duration of the forward deceleration of the vehicle
exceeds the designed threshold level.
The front airbags will work if the severity of the impact is above
the designed threshold level, comparable to an approximate
25 km/h (15 mph) collision in the U.S.A. and 30 km (18 mph)
collision in Canada when the vehicle has the impact straight
into a fixed barrier that does not move or deform.

16G022
This SRS airbag system has an indicator to inform the driver
of operating problems. If either of the following conditions
occurs, this indicates a malfunction of the airbags. Contact
your Lexus dealer as soon as possible to service the vehicle.
When the ignition key is turned to the ªONº position, the light
does not come on, 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 have a problem. If the light flashes, the side
and curtain shield airbags have a problem.16G142b

possible:
Any of the SRS airbags have been inflated.
The front of the vehicle and portion of the doors (shaded in
the illustration) were involved in an accident that was not
severe enough to cause the SRS airbags to inflate.
