Equipment to Protect Occupants/Pedestrians
SRS Air Bags
SRS Air Bags
If the vehicle receives a strong impact
from the front or side of the vehicle
when the vehicle power is switched
ON, the air bags inflate
instantaneously and lessen the impact
on the head or chest of the driver or
passenger.
The SRS air bag system protects
occupants together with the seat belts
and they are not a substitute for the
seat belts.
There are 5 types of air bags.
Vehicles with the Driver and Front
Passenger Occupant Classification
System have a sensor which detects an
impending roll-over accident.
The air bag supplemental restraint
systems are designed to provide
supplemental protection in certain
situations so seat belts are always
important in the following ways:
Without seat belt usage, the air bags
cannot provide adequate protection
during an accident. Seat belt usage is
necessary to:
Keep the occupant from being
thrown into an inflating air bag.
Reduce the possibility of injuries
during an accident that is not
designed for air bag inflation, such as
rear impact.
Reduce the possibility of injuries in
frontal, near frontal or side collisions
or roll-over accidents that are not
severe enough to activate the air
bags.
Reduce the possibility of being
thrown from your vehicle.
Reduce the possibility of injuries to
lower body and legs during an
accident because the air bags
provide no protection to these parts
of the body.

Driver's front air bag
The driver's front air bag is stored in
the center of the steering wheel.
When air bag crash sensors detect a
frontal impact of greater than
moderate force, the driver's air bag
inflates quickly helping to reduce injury
mainly to the driver's head or chest
caused by directly hitting the steering
wheel.
(With Driver and Front Passenger
Occupant Classification System)
The inflation of the driver's dual-stage
air bag is controlled in two energy
stages depending on the driver's seat
position. The driver's seat slide
position sensor is located under the
driver's seat. The sensor determines
whether the driver's seat is forward of
or behind a reference position and
sends the seat position to the
diagnostic module (SAS unit). The SAS
unit is designed to control the
deployment of the driver's air bag
depending on how close the driver's
seat is to the steering wheel.
During an impact of moderate severity,
the driver's air bag deploys with lesser
energy, whereas during more severe
impacts and when the driver's seat is
behind the reference position, it
deploys with more energy.
