FRONT SEAT
Seat adjustment precautions
Adjust the driver’s seat so that the foot pedals, steering wheel
and instrument panel controls are within easy reach of the
driver.
CAUTION:

Do not adjust the seat while the vehicle is moving as the
seat may unexpectedly move and cause the driver to
lose control of the vehicle.

Be careful not to hit the seat against a passenger,
luggage or the rear seat.
NOTICE:
Do not operate the control switch in more than one
dimension at a time. It may cause electrical overload.

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.

The SRS is designed to activate in response to a severe
frontal impact within the shaded area shown in the
illustration.
The SRS does not work in the following cases.

Impact from the side or real.

Vehicle overturn

Frontal collision at low speeds
For your safety, be sure to always wear your seat belts.

The center airbag sensor assembly consists of a safing sensor
and center airbag sensor. In a severe frontal impact, a front
airbag sensor and safing sensor, or center airbag sensor and
safing sensor detect the shock, and the center airbag sensor
assembly triggers the inflators and seat belt pretensioners.
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 an operating noise and
releases a small amount of smoke-like gas. This gas is
harmless and does not indicate a fire.

COMFORT ADJUSTMENT

Do not sit on the edge of the seat or lean over the
instrument panel when the vehicle is in use. The airbag
inflates with considerable speed and force; you may be
severely injured. Sit up straight and well back in the
seat, and always use your seat belt.
Do not put objects on or in front of the instrument panel
that houses the airbag system. They might restrict
inflation or cause personal injury.

Do not modify, remove or open any component or
wiring, such as the steering wheel, column cover, front
passenger airbag cover, front passenger airbag, center
airbag sensor assembly, front airbag sensors, or seat
belt assembly. Doing any of these may cause sudden
SRS operation or disable the system, which could
result in personal injury.
Failure to follow these instructions can result in severe
injuries.

COMFORT ADJUSTMENT

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.

COMFORT ADJUSTMENT
72
In the following cases, contact your Lexus dealer as soon as
possible:

The airbags have been inflated.

The seat belt pretensioners have been activated.

The front part of the vehicle (shaded in the illustration) was
involved in an accident not of the extent to cause the SRS
to inflate.

The pad section of the steering wheel or front passenger
airbag cover (shaded in the illustration) is scratched,
cracked, or otherwise damaged.
NOTICE:
Do not disconnect the battery cables before contacting
your Lexus dealer.
