SRS AIRBAGS
The SRS (Supplemental Restraint System) airbags
are designed to provide further protection for the
driver and front passenger in addition to the primary
safety protection provided by the seat belts.
16L118c

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 reduce injury by inflating. The driver
and front passenger airbags help to reduce injuries
mainly to the driver's or front passenger's head or
chest directly hitting the steering wheel or
dashboard.
The front passenger airbag is activated 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.

Side airbags
In response to a severe side impact, the side airbags
for the driver or front passenger work together with
the seat belts to help reduce injury by inflating. The
side airbags help to reduce injuries mainly to the
driver or front passenger's chest.
The side airbag on the passenger seat is activated even
with no passenger in the front seat.
Be sure to wear your seat belt.

COMFORT ADJUSTMENT

CAUTION
The side airbags inflate with considerable force. To
avoid potential death or serious injury when they inflate,
the driver and front passenger must:
 Wear their seat belts.
 Remain properly seated with their back upright and
against the seat at all times.

The indicator comes on when the ignition key is
turned to the ºACCº or ºONº position. It goes off
after
about 6 seconds. This means the SRS airbags
are operating properly.
The SRS warning light system monitors the airbag
sensor assembly, side airbag sensor assemblies,
inflators, warning light, interconnecting wiring and power
sources. (For details, see ºService reminder indicators
and warning buzzersº on page 62.)

COMFORT ADJUSTMENT
166The SRS airbag system is designed to activate in
response to a severe frontal impact within the
shaded area between the arrows in the illustration.
The SRS airbags will work if the severity of the impact
is above the designed threshold level, comparable to an
approximate 20 km/h (14 mph) collision when impacting
straight
into a fixed barrier that does not move or deform.
If the severity of the impact is below the above threshold
level, the SRS airbags may not work. However, this threshold velocity will be considerably
higher if the vehicle strikes an object, such as a parked
vehicle or sign pole, which can move or deform on
impact, or if it is involved in an underride collision (e.g.
a collision in which the nose of the vehicle ºunderridesº,
or goes under, the bed of a truck, etc.).
It is possible that in some collisions at the lower zone of
airbag sensor detection and activation the SRS airbags
and seat belt pretensioners will not operate all together.
For the safety of all occupants, always wear your seat
belts.

The SRS airbags are not designed to inflate if the
vehicle is involved in a rear collision, if it rolls over,
or if it is involved in a low±speed frontal collision.
The side airbags are designed to inflate when the
passenger compartment area suffers a severe
impact from the side.
