from starting if the key has not been previously registered in the vehicle's
on-board computer.
Never leave the keys inside the vehicle when you leave the vehicle.

1-7. Safety information

Before driving
Airbag system components
Your vehicle is equipped with ADVANCED AIRBAGS designed based
on US motor vehicle safety standards (FMVSS208). The airbag system
controls airbag deployment power for the driver and front passenger. The
driver airbag system consists of the driver seat’s position sensor etc. The
front passenger’s airbag system consists of the front passenger occupant
classification sensor etc.
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.

1-7. Safety information
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.
nSRS warning light
This warning light system monitors the airbag sensor assembly, front airbag sensors,
side and curtain shield airbag sensor assemblies, curtain shield airbag sensor
assemblies, driver's seat position sensor, driver's seat belt buckle switch, seat belt
pretensioner assemblies, inflators, interconnecting wiring and power sources.
(→P. 3 8 4 )
nIf the SRS airbags deploy (inflate)
lBruising and slight abrasions may result from contact with a deploying (inflating)
SRS airbag.
lA loud noise and white powder will be emitted.
lParts of the airbag module (steering wheel, airbag cover and inflator) as well as
the front 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.
lThe windshield may crack.
nOperating conditions (front airbags)
lThe 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.).
lIt 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.
lThe 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. 9 5 )
