The head-thorax air bags are integrated
into the driver and passenger seat
backrests.
Head-thorax air bag
:
Driver front air bag/passenger front air
bag
The front air bags are designed to reduce
the potential of injury in certain frontal
impacts.
Driver front air bag and passenger front
air bag are deployed
at the start of an accident with high
R
vehicle deceleration in the longitudinal
direction
independently of other air bags in the
R
vehicle being deployed
never in the event of a rollover, unless
R
high vehicle deceleration in the
longitudinal direction is detected
i
The front air bags in this vehicle have
been designed to inflate in two stages.
This allows the air bag to have different
rates of inflation that are based on the
rate of relevant vehicle deceleration
and a fastened or unfastened seat belt as
assessed by the air bag control unit.
On the passenger side, the front air bag
deployment is additionally influenced
by the passenger's weight category as
identified by the Occupant
Classification System (OCS)
Y
( page 39).
The lighter the passenger side occupant,
the higher the vehicle deceleration rate
required for the second stage inflation
of the air bag.
The air bags will not deploy in impacts
which do not exceed the system's
deployment thresholds. In such instances,
the seat belts are designed to protect you.
The passenger air bag will only be
deployed if
the system, based on OCS weight sensor
R
readings, senses that the passenger seat
is occupied and the 40
indicator lamp is not lit (
the impact exceeds a preset deployment
R
threshold
The driver front air bag is located in the
steering wheel housing, the passenger
front air bag above the glove box.

Occupant Classification System
The Occupant Classification System (OCS)
automatically turns the passenger front air
bag on or off based on the classified
occupant weight category determined by
weight sensor readings from the passenger
seat.
i
The system does also deactivate the
head-thorax air bag, the seat Emergency
Tensioning Devices, and the seat belt
