FRONT SEATS
Front seat precautions
CAUTION
The SRS side airbags are installed in the driver and front
passenger seats. Observe the following precautions.
Do not lean over the front door when the vehicle is in use.
The side airbag inflates with considerable speed and force;
you may be killed or severely injured.
 Do not modify or replace the seats or the surface of the seats
with side airbags. Such changes may disable the system, or
cause the side airbags to inflate, resulting in death or
serious injury. Consult your Lexus dealer.
 Do not use accessories for the seats which cover the parts
where the side airbags should inflate. Such accessories may
prevent the side airbags from activating correctly, causing
death or serious injury.
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.

TILT STEERING WHEEL
16E009
To change the steering wheel angle, hold the steering wheel, pull up the
lock release lever, tilt the steering wheel to the desired angle and release
the lever.
When the steering wheel is in a low position, it will spring up as you relea\
se
the lock release lever.
CAUTION
Do not adjust the steering wheel while the vehicle is moving.
 After adjusting the steering wheel, try moving it up and
down to make sure it is locked in position.
OUTSIDE REAR VIEW MIRRORS
16E010
Adjust the mirror so you can just see the side of your vehicle in the mirror.
Be careful when judging the size or distance of any object seen in the out\
side
rear view mirror on the passenger's side. It is a convex mirror with a curved
surface. Any object seen in a convex mirror will look smaller and farther away
than if seen in a normal flat mirror.
When you push the rear window defogger switch, the heater panels in the
outside rear view mirrors will quickly clear the surface.

COMFORT ADJUSTMENT69
SUPPLEMENTAL RESTRAINT SYSTEM(SRS)
The Supplemental Restraint System (SRS) consists of driver and front
passenger airbags, side airbags and seat belt pretensioners. The
combination of these 3 systems is designed to provide further protection
for the driver and front passenger when added to the primary pr otection
provided by the seat belts.
16E124

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 together with the driver and fron\
t
passenger airbags, 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.

Vehicle roll±over
The side airbags are not designed to inflate if the vehicle is rolled over.
If the impact on the body of the passenger compartment is not strong as
illustrated above, the relevant side airbag may not inflate.

7Driver and front passenger airbag 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 d\
etects
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 along with non±toxic gas. This does not indicate a fire. Be sure to wash
off any residue as soon as possible to prevent minor skin irritation.
Deployment of the airbags happen in a fraction of a second, so the airbags
must inflate with considerable force. While the system is designed to reduc\
