In any particular crash, no one can say whether an air
bag should have inflated simply because of the damage
to a vehicle or because of what the repair costs were. For
frontal air bags, inflation is determined by the angle of
the impact and how quickly the vehicle slows down in
frontal and near
-frontal impacts. For side impact air
bags, inflation is determined by the location and severity
of the impact.
What makes an air bag inflate?
In an impact of sufficient severity, the air bag sensing
system detects that the vehicle is in a crash. For both
frontal and side impact air bags, the sensing system
triggers a release of gas from the inflator, which inflates
the air bag. The inflator, air bag and related hardware are
all part of the air bag modules inside the steering wheel,
instrument panel and the side of the front seatbacks and
behind the rear seatbacks closest to the door.
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. In moderate to severe side
collisions, even belted occupants can contact the inside
of the vehicle. The air bag supplements 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 the frontal 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 the air bag. Side impact air bags would not
help you in many types of collisions, including frontal
or near frontal collisions, rollovers, and rear 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 for the driver's and right front passenger's
frontal air bags, and only in moderate to severe side
collisions for the side impact air bags.
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, the instrument panel for
the right front passenger's bag, the side of the seatback
closest to the door for the side impact air bags
-- 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 the vents
in the deflated air bags. Air bag inflation doesn't prevent
the driver from seeing or being able to steer the vehicle,
nor does it stop people from leaving the vehicle.

Restraint Systems for Children
An infant car bed (A), a special bed made for use in a
motor vehicle, is an infant restraint system designed to
restrain or position a child on a continuous flat surface.
Make sure that the infant's head rests toward the center
of the vehicle.
A rear-facing infant seat (B) provides restraint with
the seating surface against the back of the infant. The
harness system holds the infant in place and, in a crash,
acts to keep the infant positioned in the restraint.

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:If the child is sitting in a seat next to a window,
move the child toward the center of the vehicle. If
the child is sitting in the center rear seat passenger
position, move the child toward the safety belt
buckle. In either case, 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 seat
outside position, see ªRear Safety Belt Comfort
Guidesº in the Index.

Trunk Lid Tie Down
CAUTION:
Driving with the trunk lid open can allow
dangerous CO (carbon monoxide) gas to come
into your vehicle. You can't see or smell CO.
It can cause unconsciousness and even death.
If you ever need to drive with your trunk lid
open, then:
Make sure all windows, the rear seat
pass
-through and sunroof are closed.
Turn the fan on your heating and cooling
system to its highest speed, with the
setting on AUTO and temperature between
65F (18C) and 85F (29C). This forces
fresh outside air into your vehicle.
Open all air ducts on the instrument panel.
Don't use the trunk lid tie down if you are towing
a trailer because of the danger of CO.
This feature is used to secure the trunk lid if it will not
close completely, such as when carrying large packages
in the trunk.
1. Attach the clip end of the tie down to the ªDº ring
on the trunk lid (see view A).
2. Attach the hook end of the tie down to the striker
located at the center of the trunk sill (see view B).
3. Tighten the tie down by pulling the free end of the
cord until secure.
4. To remove the tie down, press the clip end release
and loosen the cord.

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:
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
With the key in the ignition switch, you can turn the
switch to four different positions.
If you cannot start your vehicle and you are unable to
remove your key from the ignition, see ªShift Lock
Releaseº in the Index.
OFF (A): This is the only position in which you can
insert or remove the key. This position locks the ignition,
steering wheel and transaxle. It's a theft
-deterrent feature.

NOTICE:
If your key seems stuck in OFF and you can't
turn it, be sure you are using the correct key;
if so, is it all the way in? If it is, then turn the
steering wheel left and right while you turn the
key hard. But turn the key only with your hand.
Using a tool to force it could break the key or the
ignition switch. If none of this works, then your
vehicle needs service.
ACCESSORY (B): This position allows you to use
things like the radio and the windshield wipers when the
engine is off. This position will allow you to turn off the
engine, but still turn the steering wheel. If your vehicle
has a column shifter, you will still be able to move the
shift lever. Use ACCESSORY if you must have your
vehicle in motion while the engine is off (for example,
if your vehicle is being pushed or towed).ON (C): This position is for driving. If your vehicle has
a floor (console) shifter and you turn off the engine, the
transaxle will lock. If you need to shift the transaxle out
of PARK (P), the ignition key has to be in ON.
START (D): This position starts the engine.
Retained Accessory Power (RAP)
The following accessories on your vehicle may be used
for up to 10 minutes after the ignition key is turned from
ON to OFF:
Radio
Power Windows
Sunroof
Power to these accessories will stop after 10 minutes or
if any door is opened. If you want power for another
10 minutes, turn the ignition key to ACCESSORY,
then back to OFF. Always leave your key in OFF when
using RAP.
