Vehicle Damage Warnings
Also, in this book you will ®nd these notices:
Notice:These mean there is something that could
damage your vehicle.
A notice will tell you about something that can damage
your vehicle. Many times, this damage would not be
covered by your warranty, and it could be costly. But the
notice will tell you what to do to help avoid the
damage.
When you read other manuals, you might see CAUTION
and NOTICE warnings in different colors or in
different words.
You'll also see warning labels on your vehicle. They use
the same words, CAUTION or NOTICE.

symbols instead of text. Symbols, used on your vehicle,
are shown along with the text describing the operation
or information relating to a speci®c component, control,

The button used to control
the passenger's heated

Safety Belts
Safety Belts: They Are for Everyone
This part of the manual tells you how to use safety
belts properly. It also tells you some things you should
not do with safety belts.
{CAUTION:
Don't let anyone ride where he or she can't
wear a safety belt properly. If you are in a
crash and you're not wearing a safety belt,
your injuries can be much worse. You can hit
things inside the vehicle or be ejected from it.
You can be seriously injured or killed. In the
same crash, you might not be, if you are
buckled up. Always fasten your safety belt,
and check that your passengers' belts are
fastened properly too.
{CAUTION:
It is extremely dangerous to ride in a cargo
area, inside or outside of a vehicle. In a
collision, people riding in these areas are more
likely to be seriously injured or killed. Do not
allow people to ride in any area of your vehicle
that is not equipped with seats and safety
belts. Be sure everyone in your vehicle is in a
seat and using a safety belt properly.
Your vehicle has a light
that comes on as a
reminder to buckle up. See
Safety Belt Reminder
Light on page 3-38.
In most states and in all Canadian provinces, the law
says to wear safety belts. Here's why:
They work.

Driver Position
This part describes the driver's restraint system.
Lap-Shoulder Belt
The driver has a lap-shoulder belt. Here's how to wear it
properly.
1. Close and lock the door.
2. Adjust the seat so you can sit up straight. To see
how, see ªSeatsº in the Index.3. Pick up the latch plate and pull the belt across you.
Don't 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.
4. Push the latch plate into the buckle until it clicks.
Pull up on the latch plate to make sure it is secure.
If the belt isn't long enough, see
Safety Belt
Extender on page 1-46.
Make sure the release button on the buckle is
positioned so you would be able to unbuckle the
safety belt quickly if you ever had to.

1. Because your vehicle has a right front passenger
air bag, always move the seat as far back as it will
go before securing a forward-facing child restraint.
See
Power Seats on page 1-4orManual Seats
on page 1-3.
If your vehicle has the passenger sensing system
and you are using a rear-facing child restraint in this
seat, make sure the frontal air bag is off. See
Passenger Sensing System on page 1-83.
When the passenger sensing system has turned off
the right front passenger's frontal air bag, the off
indicator on the inside rearview mirror will light and
stay lit when you turn the ignition to RUN or START.
2. Put the restraint on the seat.
3. Pick up the latch plate, and run the lap and shoulder
portions of the vehicle's safety belt through or
around the restraint. The child restraint instructions
will show you how.4. Buckle the belt. Make sure the release button is
positioned so you would be able to unbuckle the
safety belt quickly if you ever had to.
1-71

8. If your vehicle has the passenger sensing system
and you're using a rear-facing child restraint in this
seat, check to be sure the right front passenger's
frontal air bag is off before you begin to drive. If the
air bag has been turned off, the off indicator will
light and stay lit when the key is turned to RUN or
START.
If the on indicator is lit, the passenger's frontal air
bag has not been turned off. If this ever happens,
turn the vehicle off, unbuckle the safety belt
and perform the steps to install the rear-facing
restraint again. After restarting the vehicle, if the air
bag still doesn't turn off, install the infant restraint
in a rear seat position of the vehicle and have your
vehicle serviced as soon as possible.
To remove the child restraint, just unbuckle the vehicle's
safety belt and let it go back all the way. The safety
belt will move freely again and be ready to work for an
adult or larger child passenger.Air Bag Systems
This part explains the frontal and side impact air bag
systems.
Your vehicle has air bags ± a frontal air bag for the
driver and another frontal air bag for the right front
passenger. Your vehicle may also have a side impact
air bag. Side impact air bags are available for the driver
and right front passenger.
If your vehicle has a side impact air bag for the driver
and/or the right front passenger, the words AIR BAG will
appear on the air bag covering on the side of the
seatback closest to the door.
1-73

There is an air bag
readiness light on the
instrument panel cluster,
which shows the air
bag symbol.
The system checks the air bag electrical system for
malfunctions. The light tells you if there is an electrical
problem. See
Air Bag Readiness Light on page 3-39for more information.
Where Are the Air Bags?
The driver's frontal air bag is in the middle of the
steering wheel.
