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 electricaloverload.

Driver and front passenger airbags, and seat belt
pretensioners
Driver and front passenger airbags:In response to a severe frontal impact, the driver and
front passenger airbags work together with the seat
belts to help preventing or reduce injury by inflating,
in order to decrease the likelihood of the driver's or
front passenger's heads or chests from directly
hitting the steering wheel or dashboard.
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 front passenger airbag is activated even with no
passenger in the front seat.
The seat belt pretensioners are activated even with no
passenger in the front seat.
Be sure to wear your seat belt.

CAUTION
The driver or front passenger too close to the steering
wheel or dashboard during airbag deployment can be
killed or seriously injured. Lexus strongly recommends
that:
The driver sit as far back as possible from the
steering wheel while still maintaining control of the
vehicle.
 The front passenger sit as far back as possible from
the dashboard.
 All vehicle occupants be properly restrained using
the available seat belts.

6SRS warning light
7Airbag sensor assembly
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. Deployment of the airbags happens in a fraction of a
second, so the airbags must inflate with considerable
force. While the system is designed to reduce serious
injuries, it may also cause minor burns or abrasions and
swellings.
Parts of the airbag module (steering wheel hub,
dashboard, front seats) may be hot for several minutes,
but the airbags themselves will not be hot. The airbags
are designed to inflate only once.
A crash severe enough to inflate the driver and front
passenger airbags may break the windshield as the
vehicle buckles. In vehicles with a front passenger
airbag, the windshield may also be damaged by
absorbing some of the force of the inflating airbag.
