Rear Seat Passengers
It is very important for rear seat passengers to buckle
up! Accident statistics show that unbelted people in
the rear seat are hurt more often in crashes than those
who are wearing safety belts.
Rear passengers who are not safety belted can be
thrown out of the vehicle in a crash. And they can strike
others in the vehicle who are wearing safety belts.
Rear Seat Outside Passenger Positions
Lap-Shoulder Belt
The positions next to the windows have lap-shoulder
belts. Here is how to wear one properly.
1. Pick up the latch plate and pull the belt across you.
Do not let it get twisted.
The shoulder belt may lock if you pull the belt across
you very quickly. If this happens, let the belt go back
slightly to unlock it. Then pull the belt across you
more slowly.

Child Restraints
Older Children
Older children who have outgrown booster seats should
wear the vehicle’s safety belts.
If you have the choice, a child should sit next to a
window so the child can wear a lap-shoulder belt and
get the additional restraint a shoulder belt can provide.
Q:What is the proper way to wear safety belts?
A:If possible, an older child should wear a
lap-shoulder belt and get the additional restraint
a shoulder belt can provide. The shoulder belt
should not cross the face or neck. The lap
belt should t snugly below the hips, just touching
the top of the thighs. It should never be worn
over the abdomen, which could cause severe or
even fatal internal injuries in a crash.
Accident statistics show that children are safer if they
are restrained in the rear seat.
In a crash, children who are not buckled up can strike
other people who are buckled up, or can be thrown
out of the vehicle. Older children need to use safety
belts properly.

A booster seat (F-G) is a child restraint designed to
improve the t of the vehicle’s safety belt system.
Some booster seats have a shoulder belt positioner,
and some high-back booster seats have a ve-point
harness. A booster seat can also help a child to see out
the window.
Q:How do child restraints work?
A:A child restraint system is any device designed for
use in a motor vehicle to restrain, seat, or position
children. A built-in child restraint system is a
permanent part of the motor vehicle. An add-on
child restraint system is a portable one, which
is purchased by the vehicle’s owner.
For many years, add-on child restraints have used
the adult belt system in the vehicle. To help reduce
the chance of injury, the child also has to be
secured within the restraint. The vehicle’s belt
system secures the add-on child restraint in
the vehicle, and the add-on child restraint’s harness
system holds the child in place within the restraint.
One system, the three-point harness, has straps that
come down over each of the infant’s shoulders and
buckle together at the crotch. The ve-point harness
system has two shoulder straps, two hip straps and
a crotch strap. A shield may take the place of hip
straps. A T-shaped shield has shoulder straps that
are attached to a at pad which rests low against the
child’s body. A shelf- or armrest-type shield has
straps that are attached to a wide, shelf-like shield
that swings up or to the side.

What Will You See After an
Airbag Inates?
After the airbag inates, it quickly deates, so quickly
that some people may not even realize the airbag
inated. Some components of the airbag module – the
steering wheel hub for the driver’s airbag, the
instrument panel for the right front passenger’s bag, the
side of the seatback closest to the door for the driver’s
side impact airbag – 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
deated airbags. Airbag ination does not prevent
the driver from seeing or being able to steer the vehicle,
nor does it stop people from leaving the vehicle.
{CAUTION:
When an airbag 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 airbag
inates, then get fresh air by opening a
window or a door. If you experience breathing
problems following an airbag deployment,
you should seek medical attention.

Section 2 Features and Controls
2-1

Keys
{CAUTION:
Leaving children in a vehicle with the ignition
key is dangerous for many reasons. They
could operate the power windows or other
controls or even make the vehicle move.
The children or others could be badly injured
or even killed. Do not leave the keys in a
vehicle with children.
2-2

After initially moving the shift lever out of and back into
PARK (P), each additional shift cycle will advance
the programming from the current mode to the next
operating mode. If cycled beyond Mode 4, the vehicle
will enter operating Mode 1.
Disconnecting the vehicle’s battery for up to a year will
not affect the programmed mode.
Lockout Protection
The power door locks will not work if the key is in the
ignition and a door is open. You can override this feature
by holding the driver’s side power door lock switch for
more than three seconds.
Leaving Your Vehicle
If you are leaving the vehicle, take your key, open your
door and set the locks from inside or with the remote
keyless entry transmitter. Then get out and close
the door.
Trunk
{CAUTION:
It can be dangerous to drive with the trunk lid
open because carbon monoxide (CO) gas can
come into your vehicle. You can not see or
smell CO. It can cause unconsciousness and
even death. If you must drive with the trunk lid
open or if electrical wiring or other cable
connections must pass through the seal
between the body and the trunk lid:
Make sure all other windows are shut.Turn the fan on your heating or cooling
system to its highest speed and select the
control setting that will force outside air
into your vehicle. See Climate Control
System in the Index.
If you have air outlets on or under the
instrument panel, open them all the way.
SeeEngine Exhaust on page 2-27.
