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.

When the ignition key is removed, the steering column moves
forward away from the driver and also tilts up for easy exit and
entry.
When the key is inserted in the ignition switch, the steering column
returns to the previously set position.
NOTE: *This feature can be set inoperative. Ask your Lexus
dealer for details.
OUTSIDE REAR VIEW MIRRORS
16L016
Adjust the mirror so you can just see the side of your vehicle in
the mirror.
When the inside rear view mirror darkens in ”AUTO” mode, the
outside rear view mirrors also darken to reduce the reflection of the
headlights of the following vehicle. For details, see ”Inside rear view
mirror” on page 79.
CAUTION
Do not adjust the mirror while the vehicle is moving. It may
cause the driver to mishandle the vehicle and an accident may
occur, resulting in personal injuries.

SUPPLEMENTAL RESTRAINT
SYSTEM (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.
16L1181
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 together with the driver and
front passenger airbags, even with no passenger in the front seat.
Be sure to wear your seat belt.
CAUTION
The driver or front passenger too close to the steering wheel
or dashboard during airbag deployment can be killed or
seriously injured. Lexus strongly recommends that:
The driver sit as far back as possible from the steering
wheel while still maintaining control of the vehicle.
The front passenger sit as far back as possible from the
dashboard.
All vehicle occupants be properly restrained using the
available seat belts.
