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 electricaloverload.

Move the control switch in the desired direction.
Releasing the switch will stop the seatback in that
position.
CAUTION
To reduce the risk of sliding under the lap belt during a
collision, avoid reclining the seatback any more than
needed. The seat belts provide maximum protection in
a frontal or rear collision when the driver and the
passenger are sitting up straight and well back in the
seats. If you are reclined, the lap belt may slide past
your hips and apply restraint forces directly to the
abdomen. Therefore, in the event of a frontal collision,
the risk of personal injury may increase with increasing
recline of the seatback.

SEAT BELTS
Seat belt precautions
Lexus strongly urges that the driver and passengers in
the vehicle be properly restrained at all times with the
seat belts provided. Failure to do so could increase the
chance of injury and/or the severity of injury in accidents.
Child. Use a child restraint system appropriate for the
child until the child becomes large enough to properly
wear the vehicle's seat belts. See ºChild restraintº for
details.
If a child is too large for a child restraint system, the child
should sit in the rear seat and must be restrained using
the vehicle's seat belt. According to accident statistics,
the child is safer when properly restrained in the rear
seat than in the front seat.
If a child must sit in the front seat, the seat belts should
be worn properly. Do not let the child sit on your lap. It
does not provide sufficient restraint. If an accident
occurs and the seat belts are not worn properly, the force
of the rapid inflation of the airbag may cause severe
injury to the child.
Do not allow the child to stand up or kneel on either rear
or front seats. An unrestrained child could suf fer serious
injury during emergency braking or a collision.
Pregnant woman. Lexus recommends the use of a
seat belt. Ask your doctor for specific recommendations. The lap
belt should be worn securely
and as low as possible over the hips and not on the waist.

Replace the belt assembly (including bolts) if it
has been used in a severe impact. The entire
assembly should be replaced even if damage is
not obvious.Front seat belt buckle illumination

Opening the driver's door lights up the driver's seat
belt buckle for easy use. The same applies for the
front passenger's door and seat belt buckle.
The light remains on for 15 seconds after the door is
closed, but goes off immediately when all doors are
locked.

SUPPLEMENTAL RESTRAINTSYSTEM (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 protection provided by the seat
belts.

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.
