Vehicle Damage Warnings
Also, in this manual you will nd these notices:
Notice:These mean there is something that could
damage your vehicle.
A notice tells about something that can damage the
vehicle. Many times, this damage would not be covered
by your vehicle’s warranty, and it could be costly. But
the notice will tell 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.
There are also warning labels on the vehicle. They use
the same words, CAUTION or NOTICE.
Vehicle Symbols
The vehicle has components and labels that use
symbols instead of text. Symbols are shown along with
the text describing the operation or information
relating to a specic component, control, message,
gage, or indicator.
If you need help guring out a specic name of a
component, gage, or indicator, reference the following
topics:

Heated Seats
Your vehicle may have
heated front seats. The
buttons used to control this
feature are located on the
front doors. The engine
must be running for the
heated seat feature
to work.
To heat the entire seat, press the horizontal button with
the heated seat symbol. Press the button to cycle
through the temperature settings of high, medium and
low and to turn the heated seat off. Indicator lights
will glow to designate the level of heat selected,
three for high, two for medium, and one for low.The low setting warms the seatback and cushion until
the seat temperature is near body temperature. The
medium and high settings heat the seatback and seat
cushion to a slightly higher temperature. You will be able
to feel heat in about two minutes.
To heat only the seatback, press the vertical button with
the heated seatback symbol. An indicator light on the
seatback button will glow to designate that only the
seatback is being heated. Additional presses of
the seatback button will cycle through the heat levels for
the seatback only. Press the horizontal button again
to heat the whole seat.
The heated front seats will shut off automatically when
the ignition is turned off.

If your vehicle has this
feature, the buttons used
to control this feature
are located on the back of
the center console. The
engine must be running for
the heated seat feature
to work.To heat the seat, press the button to cycle through the
temperature settings of high and low. Press the
button a third time to turn the feature off. An indicator
light will glow for each heat setting when the feature

Returning the Seat from a Tilted to an
Upright Position
{CAUTION:
If the seatback is not locked, it could move
forward in a sudden stop or crash. That could
cause injury to the person sitting there. Always
press rearward on the seatback to be sure
it is locked.To return the seatback to an upright position, do the
following:
1. Pull the lever labeled 3 toward you.
2. While still holding lever 3 toward you, grasp the top
of the seat and pull it toward you slightly.
3. Let go of lever 3 and pull the seat completely down.
4. Push down on the seat rmly. Try pulling it up to
be sure it is locked into place.
1-12

{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 3-28.In most states and in all Canadian provinces, the law
says to wear safety belts. Here is why:They work.
You never know if you will be in a crash. If you do have
a crash, you do not know if it will be a bad one.
A few crashes are mild, and some crashes can be so
serious that even buckled up, a person would not survive.
But most crashes are in between. In many of them,
people who buckle up can survive and sometimes walk
away. Without belts they could have been badly hurt
or killed.
After more than 30 years of safety belts in vehicles, the
facts are clear. In most crashes buckling up does
matter...a lot!

How to Wear Safety Belts Properly
This part is only for people of adult size.
Be aware that there are special things to know about
safety belts and children. And there are different
rules for smaller children and babies. If a child will be
riding in your vehicle, seeOlder Children on page 1-36
orInfants and Young Children on page 1-39. Follow
those rules for everyone’s protection.
First, you will want to know which restraint systems your
vehicle has.
We will start with the driver position.
Driver Position
Lap-Shoulder Belt
The driver has a lap-shoulder belt. Here is 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 “Seats” in the Index.3. 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.
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 is not long enough, seeSafety Belt
Extender on page 1-35.
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.
1-22

Right Front Passenger Position
To learn how to wear the right front passenger’s safety
belt properly, seeDriver Position on page 1-22.
The right front passenger’s safety belt works the same
way as the driver’s safety belt – except for one thing.
If you ever pull the shoulder portion of the belt out all the
way, you will engage the child restraint locking feature.
If this happens, just let the belt go back all the way
and start again.
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.
Lap-Shoulder Belt
All rear seating positions 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 lap-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.
1-30

Never put a rear-facing child restraint in the right front
passenger’s seat unless the airbag is off. Here is why:
{CAUTION:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger’s airbag inates. This is because the
back of the rear-facing child restraint would be
very close to the inating airbag. Be sure to turn
off the airbag before using a rear-facing child
restraint in the right front seat position.
Even though the airbag off switch is designed to
turn off the passenger’s airbag, no system is fail
safe, and no one can guarantee that an airbag
will not deploy under some unusual
circumstance, even though it is turned off.
General Motors recommends that rear-facing
child restraints be secured in the rear seat, even
if the airbag is off.
If you secure a forward-facing child restraint in
the right front seat, always move the front
passenger seat as far back as it will go. It is
better to secure the child restraint in a rear seat.
{CAUTION:
If the airbag readiness light ever comes on
when you have turned off the air bag, it means
that something may be wrong with the airbag
system. The right front passenger’s airbag
could inate even though the switch is off. If
this ever happens, do not let anyone whom the
national government has identied as a
member of a passenger airbag risk group sit in
the right front passenger’s position
(for example, do not secure a rear-facing child
restraint in the right front passenger’s seat)
until you have your vehicle serviced. See
“airbag Off Switch” for more on this, including
important safety information.
You will be using a lap-shoulder belt to secure the child
restraint in this position. Be sure to follow the
instructions that came with the child restraint. Secure
the child in the child restraint when and as the
instructions say.
1-55

{CAUTION:
Airbags inate with great force, faster than the
blink of an eye. If you are too close to an
inating airbag, as you would be if you were
leaning forward, it could seriously injure you.
Safety belts help keep you in position before
and during a crash. Always wear your safety
belt, even with airbags. The driver should sit
as far back as possible while still maintaining
control of the vehicle.
{CAUTION:
Anyone who is up against, or very close to,
any airbag when it inates can be seriously
injured or killed. Airbags plus lap-shoulder
belts offer the best protection for adults, but
not for young children and infants.
CAUTION: (Continued)
CAUTION: (Continued)
Neither the vehicle’s safety belt system nor its
airbag system is designed for them. Young
children and infants need the protection that a
child restraint system can provide. Always
secure children properly in your vehicle. To
read how, seeOlder Children on page 1-36and
Infants and Young Children on page 1-39.
There is a airbag readiness
light on the instrument
panel, which shows
the airbag symbol.
The system checks the airbag electrical system for
malfunctions. The light tells you if there is an electrical
problem. SeeAirbag Readiness Light on page 3-29.
