SUPPLEMENTAL RESTRAINT
SYSTEM (SRS)
The Supplemental Restraint System (SRS) consists of
Airbags and Seat Belt Pretensioners. The combination of
these two systems provides further protection to the
driver and front passenger in a severe collision.
Airbags:
In response to a severe frontal impact, the airbags inflate
and reduce the likelihood of the driver and passenger’s
heads from directly hitting the steering wheel and
instrument panel.
Seat belt pretensioners:
In response to a severe frontal impact, the seat belts are
quickly drawn back in by the retractors so that the belts
snugly restrain the driver and front passenger.The passenger airbag is activated together with the driver
airbag, even with no passenger in the front seat.
The seat belt pretensioners are activated together with the
airbags, even with no passenger in the front seat.
This indicator comes on when the ignition key is turned to
the “ACC” or “ON” position. It goes off after about 6
seconds. This means the SRS is operating properly.
The SRS warning light system monitors the front airbag
sensors, center airbag sensor assembly, inflators, seat belt
pretensioners, warning light, interconnecting wiring and power
sources.

NOTICE:
Do not perform any of the following changes without
consulting your Lexus dealer. Such changes can
interfere with proper operation of the SRS in some
cases.

Installation of electronic items such as a mobile
two-way radio or cassette tape player.

Modifications to the suspension system.

Repairs made on or near the front fenders, front
console, steering column, steering wheel or
instrument panel near front passenger airbag or seat
belt assembly.
This SRS has a warning light to indicate operating problems.
If either of the following conditions occurs, this indicates a
malfunction of the airbags and / or seat belt pretensioners.
Even if the seat belt pretensioners should fail, the seat belt will
operate conventionally. Contact your Lexus dealer as soon as
possible to service the vehicle.

The light does not come on when the ignition key is turned
to the “ACC” or “ON” position, or remains on.

The light comes on while driving.

DRIVING POSITION MEMORY
SYSTEM
The micro computer can memorize the position of the driver’s
seat, the height of the shoulder belt anchor of the driver’s seat
belt, 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 “ON” position and
the shift lever is in the “P” position.
Setting a driving position
1. Adjust the driver’s seat, driver’s shoulder belt anchor,
tilt and telescopic steering and outside rear view mirrors
to the desired position.2. While pushing the “SET” button, push button “1” or “2”
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.

the memorized driving position profiles is being activated, the
operation will stop.
To activate the system, push the desired button (“1” or “2”)
again.
The driving position memory control system cannot be
operated while the vehicle is moving.
If the vehicle’s battery is disconnected, the computer’s
memory will be erased and the memorized positions will have
to be set again.
CAUTION:

Do not start the vehicle while the adjustments are being
made.

Take care not to select the wrong button, or the seat
could strike the rear passenger or hit your body against
the steering wheel. If this happens, you can stop the
movement by pressing another driving position
memory switch, or depressing the brake pedal.
