How does an air bag restrain?
In moderate to severe frontal or near
-frontal collisions,
even belted occupants can contact the steering wheel or the
instrument panel. Air bags supplement the protection
provided by safety belts. Air bags distribute the force of
the impact more evenly over the occupant's upper body,
stopping the occupant more gradually. But air bags would
not help you in many types of collisions, including
rollovers, rear impacts and side impacts, primarily because
an occupant's motion is not toward those air bags. Air
bags should never be regarded as anything more than a
supplement to safety belts, and then only in moderate to
severe frontal or near
-frontal collisions.
What will you see after an air bag inflates?
After an air bag inflates, it quickly deflates, so quickly that
some people may not even realize the air bag inflated.
Some components of the air bag module
-- the steering
wheel hub for the driver's air bag, or the instrument panel
for the right front passenger's bag
-- will be hot for a short
time. 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 vents in the deflated
air bags. Air bag inflation doesn't prevent the driver from
seeing or from being able to steer the vehicle, nor does it
stop people from leaving the vehicle.
CAUTION:
When an air bag inflates, 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't get out
of the vehicle after an air bag inflates, then get
fresh air by opening a window or door.

Air bags are designed to inflate only once. After they
inflate, you'll need some new parts for your air bag
system. If you don't get them, the air bag system
won't be there to help protect you in another crash.
A new system will include air bag modules and
possibly other parts. The service manual for your
vehicle covers the need to replace other parts.

Your vehicle is equipped with a diagnostic module,
which records information about the air bag system.
The module records information about the readiness
of the system, when the sensors are activated and
driver's safety belt usage at deployment.

Child Restraints
Every time infants and young children ride in vehicles,
they should have protection provided by
appropriate restraints.
Q:What are the different types of add-on
child restraints?
A:Add-on child restraints are available in four basic
types. When selecting a child restraint, take into
consideration not only the child's weight and size,
but also whether or not the restraint will be
compatible with the motor vehicle in which it will
be used.
An infant car bed (A) is a special bed made for use
in a motor vehicle. It's an infant restraint system
designed to restrain or position a child on a
continuous flat surface. With an infant car bed,
make sure that the infant's head rests toward the
center of the vehicle.

CAUTION:
Never do this.
Here two children are wearing the same belt. The
belt can't properly spread the impact forces. In a
crash, the two children can be crushed together
and seriously injured. A belt must be used by
only one person at a time.
Q:What if a child is wearing a lap-shoulder belt,
but the child is so small that the shoulder belt is
very close to the child's face or neck?
A:Move the child toward the center of the vehicle, but
be sure that the shoulder belt still is on the child's
shoulder, so that in a crash the child's upper body
would have the restraint that belts provide. If the
child is sitting in a rear outside position of a
four
-door model, see ªRear Safety Belt Comfort
Guidesº in the Index. If the child is so small that
the shoulder belt is still very close to the child's
face or neck, you might want to place the child in a
seat that has a lap belt, if your vehicle has one.

2-12 Emergency Release for Opening
Endgate/Liftgate
1. Peel back or slit the carpet locally to expose the
access hole in the trim panel.
2. Use a thin screwdriver
to reach through the
access holes in both the
trim panel and the
hardware cover.
Pry the release lever
toward the passenger's
side until the glass latch
pops open.
3. Reattach the carpet securely.
Endgate-Mounted Spare
If your vehicle has an endgate-mounted spare tire
carrier, you must move the carrier arm out of the way to
open the glass.
Here's how to move the arm:
1. Squeeze the release handle to free the carrier arm.
2. Swing the carrier arm away from the endgate. You
may need to give it a slight tug.
3. To latch the carrier arm, swing it toward the endgate.

New Vehicle ªBreak-Inº
NOTICE:
Your vehicle doesn't need an elaborate
ªbreak
-in.º But it will perform better in the long
run if you follow these guidelines:

Keep your speed at 55 mph (88 km/h) or
less for the first 500 miles (805 km).

Don't drive at any one speed
-- fast or
slow
-- for the first 500 miles (805 km).
Don't make full
-throttle starts.

Avoid making hard stops for the first
200 miles (322 km) or so. During this time
your new brake linings aren't yet broken
in. Hard stops with new linings can mean
premature wear and earlier replacement.
Follow this breaking
-in guideline every
time you get new brake linings.

Don't tow a trailer during break
-in.
See ªTowing a Trailerº in the Index for
more information.
Ignition Positions
CAUTION:
Leaving children in a vehicle with the ignition
key is dangerous for many reasons. A child or
others could be injured or even killed. They could
operate power windows or other controls or even
make the vehicle move. Don't leave the keys in
the vehicle with children.
Use the key to turn the ignition switch to five
different positions.

2-17
ACCESSORY (A): This position lets you use things
like the radio and the windshield wipers when the
engine is off. Push in the key and turn it toward you.
Your steering wheel will remain locked, just as it was
before you inserted the key.
NOTICE:
Don't operate accessories in the ACCESSORY
position for long periods of time. Prolonged
operation of accessories in the ACCESSORY
position could drain your battery and prevent
you from starting your vehicle.
LOCK (B): This position locks your ignition, steering
wheel and transmission. It's a theft
-deterrent feature.
You will only be able to remove your key when the
ignition is turned to LOCK.
OFF (C): This position lets you turn off the engine but
still turn the steering wheel. Use OFF if you must have
your vehicle in motion while the engine is off (for
example, if your vehicle is being towed).
RUN (D): This is the position for driving.
START (E): This position starts your engine.
