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.

COMFORT ADJUSTMENT
141
CAUTION
Persons should ride in their seats properly wearing
their seat belts whenever the vehicle is moving.
Otherwise, they are much more likely to suffer serious
bodily injury in the event of sudden braking or a
collision.
When using the seat belts, observe the following:
Use the belt for only one person at a time. Do not use
a single belt for two or more people ± even children.
 Avoid reclining the seatbacks too much. The seat
belts provide maximum protection when the
seatbacks are in the upright position. (See
ºAdjusting seatback angleº.)
 Be careful not to damage the belt webbing or
hardware. Take care that they do not get caught or
pinched in the seat or doors.
 Inspect the belt system periodically. Check for cuts,
fraying, and loose parts. Damaged parts should be
replaced. Do not disassemble or modify the system.
 Keep the belts clean and dry. If they need cleaning,
use a mild soap solution or lukewarm water. Never
use bleach, dye, or abrasive cleaners ± they may
severely weaken the belts. (See ºCleaning the
interiorº on page 475 for instructions.)
