Adjust the position of the lap and shoulder belts.
1Position the lap belt as low as possible on your hips Ð not
on your waist.
2Adjust it to a snug fit by pulling the shoulder portion
upward through the latch plate.
CAUTION
 Both high-positioned lap belts and loose-fitting
belts could cause serious injuries due to sliding
under the lap belt during a collision or other
unintended event. Keep the lap belt positioned as
low on hip as possible.
 Do not place the shoulder belt under your arm.

Front and second outside seat belts only
Adjust the shoulder anchor position to your size.
To raise the anchor position, push the anchor up. To lower the
anchor position, support the anchor while you push the lock
release button then slide the anchor down. After the
adjustment, make sure the anchor is locked in position.
CAUTION
Always make sure the shoulder belt is positioned
across the center of your shoulder. The belt should be
kept away from your neck, but not falling off your
shoulder. Failure to do so could reduce the amount of
protection in an accident and cause serious injuries in
a collision.

Seat belt extender
If your seat belts cannot be fastened securely because they are
not long enough, a personalized seat belt extender is available
from your Lexus dealer free of charge.
Please contact your local Lexus dealer to order the proper
required length for the extender. Bring the heaviest coat you
expect to wear for proper measurement and selection of
length. Additional ordering information is available at your
Lexus dealer.
CAUTION
When using the seat belt extender, observe the
following precautions. Failure to follow these
instructions could reduce the effectiveness of the seat
belt restraint system in case of an accident, increasing
the chance of personal injury.
Remember that the extender provided for you may
not be safe when used on a different vehicle, for
another person, or at a different seating position than
the one originally intended. If the seat belt extender has been connected to the
driver's seat belt buckle without wearing the seat belt
when using the extender in the driver's seat, the SRS
driver's airbag system will judge that the driver wears
the seat belt even if not wearing it. In this case, the
driver's airbag may not activate correctly, causing
death or serious injury in the event of collision. Be
sure to wear the seat belt with the seat belt extender.

OCCUPANT RESTRAINT SYSTEMS
149
Be sure to wear the seat belt without the seat belt
extender if you can fasten the seat belt without the
extender.
 Do not use the seat belt extender when installing a
child restraint system on the front or rear passenger
seat. If installing a child restraint system with the
seat belt extender connected to the seat belt, the seat
belt will not securely hold the child restraint system,
which could cause death or serious injury to the child
or other passengers in the event of collision.
To connect the extender to the seat belt, insert the tab into
the seat belt buckle so that the PRESSº signs on the
buckle release buttons of the extender and the seat belt
are both facing outward as shown.
You will hear a click when the tab locks into the buckle.
When releasing the seat belt, press on the buckle release
button on the extender, not on the seat belt. This helps prevent
damage to the vehicle interior and extender itself.
When not in use, remove the extender and store in the vehicle
for future use.

CAUTION
After inserting the tab, make sure the tab and buckle
are locked and that the lap and shoulder portions of
the belt and the seat belt extender 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, because it cannot
protect an adult occupant or your child from injury.
Seat belt pretensioners
The driver and front passenger's seat belt pretensioners
are designed to be activated in response to a severe
frontal impact or a vehicle rollover.
When the sensor detects a severe frontal impact or a vehicle
rollover, the front seat belts are quickly drawn back by the
retractors so that the belts snugly restrain the front seat
occupants.
The seat belt pretensioners are activated even if there is no
passenger sitting in the front seat.
The seat belt pretensioners and SRS airbags may not operate
together in case of collisions at a certain speeds and angles.

Roll sensing of curtain shield airbags off (RSCA OFF)indicator light
The seat belt pretensioners will not operate in a vehicle rollover
if the RSCA OFFº indicator light is on. For details, see Roll
sensing of curtain shield airbags off switchº on page 183.

1Front airbag sensors
2Seat belt pretensioner assemblies
3SRS warning light
4Airbag sensor assembly
The seat belt pretensioner system consists mainly of the above
components, and their locations are shown in the illustration.
The seat belt pretensioners are controlled by the airbag sensor
assembly. The airbag sensor assembly consists of a safing
sensor and airbag sensor.
When the seat belt pretensioners are activated, an operating
noise may be heard and a small amount of non-toxic gas may
be released. This does not indicate that a fire is occurring. This
gas is normally harmless.
Once the seat belt pretensioners have been activated, the seat
belt retractors remain locked.

CAUTION
Do not modify, remove, strike or open the seat belt
pretensioner assemblies, airbag sensor or
surrounding area or wiring. Failure to follow these
instruction may prevent the seat belt pretensioners
from activating correctly, cause sudden operation of
the system or disable the system, which could result
in death or serious injury. Consult your Lexus dealer
about any repairs and modifications.
 Do not modify or change the suspension system.
Such changes may cause the curtain shield airbags
to inflate accidentally, which could result in death or
serious injury. Consult your Lexus dealer about any
repair and modification.
 Do not use tires or wheels other than the
manufacture's recommended size. Such a use may
cause the curtain shield airbags and seat belt
pretensioners to inflate accidentally, which could
result in death or serious injury. For details, see
Checking and replacing tiresº on page 574.
 Do not place luggage heavier than specified on the
roof luggage carrier. Such luggage may cause the
curtain shield airbags and seat belt pretensioners to
inflate accidentally, which could result in death or
serious injury. For details, see Roof luggage
carrierº on page 109.
