{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
Rear Safety Belt Comfort
Guides for Children and Small Adults on
page 1-29
. 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.

Child Restraint Systems
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 ¯at
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.
1-38

When Should an Air Bag In¯ate?
An air bag is designed to in¯ate in a moderate to severe
frontal, or near-frontal crash. The air bag will in¯ate
only if the impact speed is above the system's designed
©threshold level©. If your vehicle goes straight into a
wall that doesn't move or deform, the threshold level is
about 9 to 16 mph (14 to 26 km/h). The threshold
level can vary, however, with speci®c vehicle design, so
that it can be somewhat above or below this range. If
your vehicle strikes something that will move or deform,
such as a parked car, the threshold level will be
higher. The air bag is not designed to in¯ate in rollovers,
rear impacts, or in many side impacts because in¯ation
would not help the occupant.
In any particular crash, no one can say whether an air
bag should have in¯ated simply because of the damage
to a vehicle or because of what the repair costs were.
In¯ation is determined by the angle of the impact
and how quickly the vehicle slows down in frontal or
near-frontal impacts.
The air bag system is designed to work properly under
a wide range of conditions, including off-road usage.
Observe safe driving speeds, especially on rough
terrain. As always, wear your safety belt. See
Off-Road
Driving with Your Four-Wheel-Drive Vehicle on
page 4-15
for more tips on off-road driving.
What Makes an Air Bag In¯ate?
In an impact of sufficient severity, the air bag sensing
system detects that the vehicle is in a crash. The
sensing system triggers a release of gas from the
in¯ator, which in¯ates the air bag. The in¯ator, air bag,
and related hardware are all part of the air bag
modules inside the steering wheel and in the instrument
panel in front of the right front passenger.
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 many
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.

Remote Rear Glass Release
The REAR HATCH button,
located to the right of the
steering wheel on the
instrument panel, allows
you to release the
rear glass from inside the
vehicle.
If your vehicle has an automatic transmission, your shift
lever must be in PARK (P) or NEUTRAL (N) for the
release to work.
If you have a manual transmission, you must apply your
parking brake or have the ignition off before you can
open the tailgate glass.
Emergency Release for Opening
Tailgate
1. Peel back or slit the carpet to expose the access
hole in the trim panel.
2. Use a thin object to
reach through the
access holes in both
the trim panel and
the hardware cover.
3. Pry the release lever toward the passenger's side
until the glass latch pops open.
4. Reattach the carpet securely.

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 tailgate. You
may need to give it a slight tug.
3. Latch the carrier arm by swinging it toward the
tailgate.

Starting and Operating Your
Vehicle
New Vehicle Break-In
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 ®rst 500 miles (805 km).
·Don't drive at any one speed Ð fast or
slow Ð for the ®rst 500 miles (805 km). Don't
make full-throttle starts.
·Avoid making hard stops for the ®rst 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, you can turn it to ®ve
different positions.
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.
A (ACCESSORY):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.
2-19

Your steering wheel will remain locked, just as it was
before you inserted the key.
{CAUTION:
On manual transmission vehicles, turning the
key to LOCK will lock the steering column and
result in a loss of ability to steer the vehicle.
This could cause a collision. If you need to
turn the engine off while the vehicle is moving,
turn the key only to OFF. Don't press the key
release button while the vehicle is moving.
Notice:If your key seems stuck in LOCK 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.
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.
B (LOCK):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.C (OFF):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).
D (RUN):This is the position for driving.
E (START):This position starts your engine.
Key Release Button
The key cannot be
removed from the ignition
of manual transmission
vehicles unless the
key release button is
pressed.
To remove the key, turn the ignition switch to OFF.
Then turn the key to LOCK while pressing the key
release button. Pull the key straight out.
