What Will You See After an
Air Bag Inates?
After the air bag inates, it quickly deates, so quickly
that some people may not even realize the air bag
inated. Some components of the air bag module will be
hot for a short time. These components include the
steering wheel hub for the driver’s frontal air bag and the
instrument panel for the right front passenger’s frontal
air bag. For vehicles with side impact air bags, the side
of the seatback closest to the driver’s and/or right
front passenger’s door will be hot. The parts of the bag
that come into contact with you may be warm, but
not too hot to touch. There will be some smoke and dust
coming from the vents in the deated air bags. Air bag
ination doesn’t prevent the driver from seeing or
being able to steer the vehicle, nor does it stop people
from leaving the vehicle.
{CAUTION:
When an air bag inates, there is dust in the air.
This dust could cause breathing problems for
people with a history of asthma or other
breathing trouble. To avoid this, everyone in the
vehicle should get out as soon as it is safe to do
so. If you have breathing problems but can not
get out of the vehicle after an air bag inates,
then get fresh air by opening a window or a
door. If you experience breathing problems
following an air bag deployment, you should
seek medical attention.

smell CO. It can cause unconsciousness and
even death. If you must drive with the cargo

connections must pass through the seal
between the body and the midgate:
Make sure all windows are shut.
Turn the fan on your heating or cooling
system to its highest speed on the setting
that brings in outside air. This will force
outside air into your vehicle. See
Automatic Climate Control System on
page 3-22.
If you have air outlets on or under the
instrument panel, open them all the way.
SeeEngine Exhaust on page 2-47.

in a crash or sudden maneuver. People in the
vehicle could be injured. Whenever you store
the rear glass in the vehicle, always be sure
that it is stored securely in the midgate
storage pocket.
Do not remove the rear glass when the rear defroster is
on. If you remove the rear glass with the rear defroster
on, you may see a discharge spark coming from
the latch area.
To remove the rear glass do the following:
1. Fold the rear seats. SeeRear Seat Operation on
page 1-7for more information. The front seats
may have to be moved forward slightly to allow the
rear seats to fold completely.
Although the rear glass can be removed without
folding the rear seats, you will not be able to access
the rear glass storage pocket. Be sure to fold the
seatsbeforeremoving the rear glass.

5. Load the rear glass into the storage pocket in the
midgate, guiding the lower edge of the rear glass
behind the three rear glass retaining tabs (E).
Hold the rear glass at against the storage pocket,
with grab handles facing you, until the next step.
