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.

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
