Fastening front and rear seat belts
16L115a
Adjust the seat as needed and sit up straight and
well back in the seat. To fasten your belt, pull it out
of the retractor and insert the tab into the buckle.
You will hear a click when the tab locks into the buckle.
The seat belt length automatically adjusts to your size
and the seat position.
The retractor will lock the belt during a sudden stop or on
impact. It also may lock if you lean forward too quickly.
A slow, easy motion will allow the belt to extend, and you
can move around freely.When a passenger's shoulder belt is completely
extended and is then retracted even slightly, the belt is
locked in that position and cannot be extended. This
feature is used to hold the child restraint system
securely.
(For details, see ºChild restraintº on page 176.)
To free the belt again, fully retract the belt and then pull
the belt out once more.
If the seat belt cannot be pulled out of the retractor, firmly
pull the belt and release it. You will then be able to
smoothly pull the belt out of the retractor.

turned to the ºACCº or ºONº position. It goes off
after about 6 seconds. This means the SRS is
operating properly.
The SRS warning light system monitors the airbag
sensor assemblies, inflators, seat belt pretensioners,
warning
light, interconnecting wiring and power sources.

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.

This SRS has an indicator to inform the driver of
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 belts will operate
conventionally. Contact your Lexus dealer as soon as
possible to service the vehicle.
 The light does not come on as described above.
 The light 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 fail. If the light flashes, the side
airbags and/or seat belt pretensioners fail.

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 seat until the seat belt is fixed. It cannot protect
your child from injury.

cannot be extended.
To hold the infant seat securely, make sure the belt is in
the lock mode before letting the belt retract.

anchor,
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.
