A front air bag will not be deployed in a lateral rollover unless the rollover also generates
a longitudinal deceleration rate meeting the system’s deployment threshold sensed early
in the collision.
Special features of dual-stage front air bags.
If the vehicle is equipped with dual-stage front air bags, the front air bag is initially
inflated with a single inflator when a first activation threshold is reached. If a second
threshold is reached, within the few milliseconds in which the determination to deploy is
made, a second inflator provides additional inflation to
increase the inflation rate of the
air bag to help address the higher deceleration rate sensed with respect to the accident.
If the vehicle is equipped with a front passenger weight classification system, the body
weight of the front passenger is taken into account along with the accident severity and
the seat belt status when calculating the air bag inflation rate.
Knee air bags supplement the function of the knee bolster in head-on collisions that
exceed the deployment threshold.
Advanced Systems.
Special features of an Occupant Classification System.
If your vehicle is equipped with an Occupant Classification System (OCS), it automatically
turns the passenger front air bag on or off based on the classified occupant size category,
determined by weight sensor readings from the front passenger seat.
The system is not designed to deactivate a side impact air bag or window curtain air bag.
If OCS classified the occupant sitting in the front passenger seat as an adult, the
passenger front air bag will be enabled and deploy in an accident meeting the respective
air bag deployment criteria. If OCS classified the front passenger seat occupant as a small
occupant, depending on weight, the passenger front air bag may or may not be enabled.
The passenger front air bag will be disabled and the PASS AIR BAGOFF indicator lamp is
lit, if the system:
•
classified the front passenger seat occupant as child-sized at a certain weight level or
•
classified the front passenger seat as empty.
In order for OCS to classify the front seat passenger as it is intended to operate, the front
passenger seat occupant must always be seated and belted properly (seat back nearly
upright, back against the seatback and feet on the floor). In addition, any circumstance
that results in the system misreading the passenger seat occupant’s correct weight
category must be avoided (for example transferring the passenger weight to the armrest
by leaning on it, attaching objects to the seatback or putting items under, on or around
the seat or seat back). You need to make sure that the passenger front seat has clearance
in all directions at all times. Otherwise the OCS may not be able to properly approximate
