2003 Lexus GS300 light

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.
16G022
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.

3Landing hard or vehicle falling
The SRS airbags may also deploy if a serious impact
occurs to the underside of your vehicle. Some examples
are shown in the illustration.

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
In the following cases, contact your Lexus dealer as soon as
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.

2. Fully extend the shoulder belt to put it in the lock mode.
When the belt is then retracted even slightly, it cannot be
extended.
To hold the infant seat securely, make sure the belt is in the lock
mode before letting the belt retract.
16G069
3. While pressing the infant seat firmly against the seat
cushion and seatback, let the shoulder belt retract as far as it
will go to hold the infant seat securely.

16G046
1. Run the lap and shoulder belt through or around the
convertible seat following the instructions provided by its
manufacturer and inserting the tab into the buckle taking care
not to twist the belt. Keep the lap portion of the belt tight.
CAUTION
After inserting the tab, make sure the tab and buckle
are locked and that the lap and shoulder portions of
the belt 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 child restraint system until the seat belt is fixed.
It cannot protect your child from injury.
16G047
2. Fully extend the shoulder belt to put it in the lock mode.
When the belt is then retracted slightly, it cannot be extended.
To hold the convertible seat securely, make sure the belt is in
the lock mode before letting the belt retract.

DRIVING POSITION MEMORY
SYSTEM
A microcomputer will memorize the position of the driver's
seat, and the positions of the tilt and telescopic steering, and
outside rear view mirrors. Two different driving position
profiles can be entered into the computer's memory.
Recording a driving position in the computer's memory can
only be done when the ignition key is in the ºONº position and
the selector lever is in the ºPº position.
Setting the driving position
16G064a
1. Adjust the driver's seat, tilt and telescopic steering and
outside rear view mirrors to the desired position.
2. While pushing the ºSETº button, push button º1º or º2º
until the signal beeps.The beep sound means that the positions are recorded in the
computer's memory.
By repeating these two steps and pressing the remaining
button, the driving position for another driver can be recorded.
To set a new memorized position, select the desired position
and perform step 2. The previous memory will be erased and
the new position will be set.
To make only slight changes to an already memorized position,
the easiest way is to first activate the memorized position, then
make the desired changes and perform step 2 above.
Recalling the memorized position
16G065a
When you push button º1º or º2º, the driving position will
be automatically adjusted to the position recorded for that
button.
