the direction and severity of impact. Both
side curtain airbags are deployed in a
rollover. The airbag system includes:aTwo SRS (Supplemental Restraint System)

in the center of the steering wheel; the
front passenger’s airbag is stored in the
dashboard. Both are marked SRS

uuAirbags uFront Airbags (SRS)
Safe Driving
Front airbags are designed to inflate during moderate-to-severe frontal collisions.
When the vehicle decelerates suddenly, the sensors send information to the control
unit which signals one or both front airbags to inflate.
A frontal collision can be either head-on or angled between two vehicles, or when a
vehicle crashes into a stationary object, such as a concrete wall.
While your seat belt restrains your torso, the
front airbag provides supplemental protection
for your head and chest.
The front airbags deflate immediately so that
they won’t interfere with the driver’s visibility
or the ability to steer or operate other
controls.
The total time for inflation and deflation is so fast that most occupants are not
aware that the airbags deployed until they see them lying in front of them.■

How the Front Airbags Work
1 How the Front Airbags Work
Although the driver’s and front passenger’s airbags
normally inflate within a split second of each other, it
is possible for only one airbag to deploy. This can
happen if the severity of a collision is at the margin,
or threshold that determines whether or not the
airbags will deploy. In such cases, the seat belt will
provide sufficient protection, and the supplemental
protection offered by the airbag would be minimal.

Safe Driving
■When front airbags should not deploy
Minor frontal crashes: Front airbags were designed to supplement seat belts and
help save lives, not to prevent minor scrapes, or even broken bones that might occur
during a less than moderate-to-severe frontal crash.
Side impacts: Front airbags can provide protection when a sudden deceleration
causes a driver or front passen ger to move toward the front of the vehicle. Side
airbags and side curtain airbags have been specifically designed to help reduce the
severity of injuries that can occur during a moderate-to-severe side impact which
can cause the driver or passenger to mov e toward the side of the vehicle.
Rear impacts: Head restraints and seat belts are your best protection during a rear
impact. Front airbags cannot provide any significant protection and are not designed
to deploy in such collisions.
Rollovers: Seat belts, and in vehicles equipped with a rollover sensor, side airbags,
and side curtain airbags offer the best protection in a rollover. Because front airbags
could provide little if any protection, they are not designed to deploy during a
rollover.■When front airbags deploy with little or no visible damage
Because the airbag system senses su dden deceleration, a strong impact to the
vehicle framework or suspension might cause one or more of the airbags to deploy.
Examples include running into a curb, the edge of a hole, or other low fixed object
that causes a sudden deceleration in the vehicle chassis. Since the impact is
underneath the vehicle, damage may not be readily apparent.■When front airbags may not deploy, eve n though exterior damage
appears severe
Since crushable body parts absorb crash energy during an impact, the amount of
visible damage does not always indicate proper airbag operation. In fact, some
collisions can result in severe damage but no airbag deployment because the airbags
would not have been needed or would not have provided protection even if they
had deployed.

■When the passenger airbag off
indicator comes on
The indicator comes on to alert you that the
passenger’s front airbag has been turned off.
This occurs when the front passenger’s weight
sensors detect 65 lbs (29 kg) or less, the
weight of an infant or small child, on the seat.
Infants and small children should always ride properly restrained in a back seat.
2 Child Safety P. 54Objects placed on the seat can also cause the indicator to come on.
If the front passenger seat is empty, the passenger’s front airbag will not deploy and
the indicator will not come on.■
Passenger Airbag Off Indicator
1 Passenger Airbag Off Indicator
If the indicator comes on with no front passenger and
no objects on the passenger’s seat, or with an adult
riding there, something may be interfering with the
weight sensors, such as:•An object hanging on the seat or in the seat-back
pocket.•A child seat or other object pressing against the
rear of the seat-back.•A rear passenger pushing or pulling on the back of
the front passenger’s seat.•The front seat or seat-back is forced back against
an object on the seat or floor behind it.•An object placed under the front passenger’s seat.
If none of these conditions exist, have your vehicle
checked by a dealer as soon as possible.
The passenger airba g off indicator may come on and
goes off repeatedly if the total weight on the seat is
near the airbag cutoff threshold.

2 Exhaust Gas Hazard P. 66
To lock the seat-back upright, push it backwards until
it locks.
When returning a seat-back to it’s original position,
push it firmly back. Also, make sure all rear shoulder
belts are positioned in front of the seat-back, and the
center shoulder belt is re-positioned in the guide.
Make sure that the folded seat-back does not press
against the front passenger seat, as this can cause the
weight sensors in the front passenger seat to work
improperly. 2 Passenger Airbag Off Indicator P. 52
Also make sure all items in the trunk or items
extending through the opening into the rear
seats are properly secured. Loose items can fly
forward if you have to brake hard.
The front seat(s) must be far enough forward so they
do not interfere with the rear seats as they fold
