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.

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.

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
Side airbags:In response to a severe side impact, the side airbag
for the driver or front passenger works together with
the seat belt to help preventing or reducing injury by
inflating, in order to decrease the impact mainly on
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.

CAUTION
SRS side airbags inflate with considerable force. To
avoid potential death or serious injury during inflation
of a side airbag, Lexus strongly recommends that the
driver and front passenger;
Wear their seat belt.
Remain properly seated with their back against the
seat at all times.

145 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 is
operating properly.
The SRS warning light system monitors the airbag
sensor assemblies, front airbag sensors, inflators, seat
belt pretensioners, warning light, interconnecting wiring
and power sources. (For details, see ºService reminder
indicators and warning buzzersº on page 65 for
instructions.)

146The driver and front passenger airbags and seat belt
pretensioners are designed to activate in response
to a severe frontal impact within the shaded area
between the arrows in the illustration.
There may be the case that the driver and passenger
airbags and seat belt pretensioners will not activate with
such an impact in which the occupant wearing the seat
belt correctly would not get serious injury.
The driver and front passenger airbags and seat belt
pretensioners will work if the severity of the impact is
above the designed threshold level, comparable to an
approximate 25 km/h (15 mph) collision in the U.S.A.
and 30 km (18 mph) collision in Canada 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 driver and front passenger airbags and seat
belt pretensioners 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 with collision severity at the marginal level
of driver and passenger airbag sensor detection and
activation that only one of your vehicle's driver and front
passenger airbags and seat belt pretensioners will work.
For the safety of all occupants, be sure to always wear
seat belts.

1Collision from the rear
2Vehicle rollover
The driver and front passenger airbags and seat belt
pretensioners are not designed to inflate if the
vehicle is subjected to a rear impact, 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 gets a severe impact from
the side.
The side airbags may rather not to activate in the impact
in which the occupant wearing the seat belt correctly
would not get serious injury.

1Collision from the side at an angle
2Collision from the side to the vehicle body
other
than the passenger compartment
The side airbags may not inflate if the vehicle is
subjected to a collision from the side at an angle, or
a collision to the side of the vehicle body other than
the passenger compartment, which impact is not
severe enough for the passenger compartment.
