Before driving
The main SRS airbag system components are shown above. The SRS air-
bag system is controlled by the airbag sensor assembly. The airbag sen-
sor assembly consists of a safing sensor and an airbag sensor.
In certain types of severe frontal or side impacts, the SRS airbag system
triggers the airbag inflators. A chemical reaction in the inflators quickly
fills the airbags with non-toxic gas to help restrain the motion of the occu-
pants.
■If the SRS airbags deploy (inflate)
●Bruising and slight abrasions may result from contact with a deploying (inflating)
SRS airbag.
●A loud noise and white powder will be emitted.
●Parts of the airbag module (steering wheel hub, airbag cover and inflator) as
well as the seats, and parts of the front pillar, rear pillar and roof side rail, may be
hot for several minutes. The airbag itself may also be hot.
●The front windshield may crack.
■Operating conditions (front airbags)
●The SRS front airbags will deploy if the severity of the frontal impact is above the
designed threshold level, comparable to an approximate 15 mph (25 km/h) col-
lision when the vehicle impacts straight into a fixed barrier that does not move
or deform.
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 the vehicle is involved in an underride collision (e.g. a collision in
which the front of the vehicle “underrides”, or goes under, the bed of a truck, etc.).
●It is possible that in some collisions where the forward deceleration of the vehi-
cle is very close to the designed threshold level, the SRS front airbags and the
seat belt pretensioners may not activate together.
●The SRS front passenger airbag will not activate if there is no passenger sitting
in the front passenger seat. However, the front passenger airbag may deploy if
luggage is put in the seat, or the seat belt is fastened, even if the seat is unoccu-
pied. (→P. 88)

■Operating conditions (side and curtain shield airbags)
●The SRS side airbags and curtain shield airbags are designed to inflate when the
passenger compartment is subjected to a severe impact from the side.
●The SRS side airbag on the passenger seat will not activate if there is no passen-
ger sitting in the front passenger seat. However, the side airbag on the passen-
ger seat may deploy if luggage is put in the seat, even if the seat is unoccupied.
(→P. 8 8 )
■Conditions under which the SRS airbags may deploy (inflate), other than a colli-
sion
The SRS front airbags may also deploy if a serious impact occurs to the underside of
your vehicle. Some examples are shown in the illustration.
■Types of collisions that may not deploy the SRS airbag (front airbags)
The SRS front airbags are generally not designed to inflate if the vehicle is involved
in a side or rear collision, if it rolls over, or if it is involved in a low-speed frontal colli-
sion. But, whenever a collision of any type causes sufficient forward deceleration of
the vehicle, deployment of the SRS front airbags may occur.
●Hitting a curb, edge of pavement or hard
surface
●Falling into or jumping over a deep hole
●Landing hard or vehicle falling
●Collision from the rear
●Collision from the side
●Vehicle rollover

Front passenger occupant classification system
Your vehicle is equipped with a front passenger occupant classification sys-
tem. This system detects the conditions of the front passenger seat and
activates or deactivates the devices for front passenger.
