The front air bags in this vehicle have been
designed to inflate in two stages. This allows
the air bags to have different rates of inflation
that are based on the vehicle deceleration
rate as assessed by the air bag control unit.
On the front passenger side, front air bag

deployment is additionally influenced by
the passenger’s weight category as identified
by the Occupant Classification System (OCS)
(

page 49).
The lighter the front passenger side
occupant, the higher the vehicle deceleration
rate required for second stage inflation of
front air bag
2
.
The air bags will not deploy in impacts which
do not exceed the system’s preset
deployment thresholds. You will then be
protected by the fastened seat belts.
The front air bags will not deploy in the event
of a rollover unless the vehicle’s rate of
longitudinal deceleration or acceleration
exceeds the preset deployment threshold for
the front air bags.
The front passenger front air bag

will only
be deployed if

the system, based on OCS weight sensor
readings, detects that the front passenger
seat is occupied

of the driver or front passenger on the side of
the vehicle on which the impact occurs.
The side impact air bags
