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:
Seats and Restraint Systems in Section 1
Features and Controls in Section 2
Instrument Panel Overview in Section 3

You can also reshape the side wing area of the lower
seatback for more lateral support.
To increase support, press and hold the top of the
control. To decrease support, press and hold the bottom
of the control. Let go of the control when the lower
seatback reaches the desired level of support.
Your vehicle may have a memory function which allows
seat settings to be saved and recalled. SeeMemory
Seat on page 2-79for more information.
Heated Seats
If your vehicle is equipped
with this feature, the
buttons are located on the
front doors. The engine
must be running for
the heated seats to work.To heat the entire seat, press the horizontal button with
the heated seat and seatback 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 be lit 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 be lit 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.

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:
Do not let anyone ride where he or she cannot
wear a safety belt properly. If you are in a
crash and you are 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.
SeeSafety Belt Reminder
Light on page 3-33.

Q:If I am a good driver, and I never drive far from
home, why should I wear safety belts?
A:You may be an excellent driver, but if you are in an
accident — even one that is not your fault — you
and your passengers can be hurt. Being a good
driver does not protect you from things beyond your
control, such as bad drivers.
Most accidents occur within 25 miles (40 km) of
home. And the greatest number of serious injuries
and deaths occur at speeds of less than 40 mph
(65 km/h).
Safety belts are for everyone.
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 1-30
orInfants and Young Children on page 1-32. 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.

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.
2. Push the latch plate into the buckle until it clicks.
Pull up on the latch plate to make sure it is secure.When the shoulder belt is pulled out all the way,
it will lock. If it does, let it go back all the way and
start again.
If the belt is not long enough, seeSafety Belt
Extender on page 1-29.
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.
3. To make the lap part tight, pull down on the buckle
end of the belt as you pull up on the shoulder part.

When choosing a child restraint, be sure the child
restraint is designed to be used in a vehicle. If it is,
it will have a label saying that it meets federal motor
vehicle safety standards.
Then follow the instructions for the restraint. You may
nd these instructions on the restraint itself or in a
booklet, or both. These restraints use the belt system or
the LATCH (Lower Anchors and Tethers for Children)
system in your vehicle, but the child also has to be
secured within the restraint to help reduce the chance of
personal injury. When securing an add-on child
restraint, refer to the instructions that come with the
restraint which may be on the restraint itself or in
a booklet, or both, and to this manual. The child restraint
instructions are important, so if they are not available,
obtain a replacement copy from the manufacturer.
Keep in mind that an unsecured child restraint can move
around in a collision or sudden stop and injure people
in the vehicle. Be sure to properly secure any child
restraint in your vehicle – even when no child is in it.Where to Put the Restraint
Accident statistics show that children are safer if they
are restrained in the rear rather than the front seat.
General Motors recommends that child restraints
be secured in a rear seat including an infant riding in a
rear-facing infant seat, a child riding in a forward-facing
child seat and an older child riding in a booster seat.
Never put a child in a rear-facing child restraint in
the right front passenger seat unless your vehicle has
the passenger sensing system or an airbag off switch
and the passenger airbag status indicator or the airbag
off light shows off. Never put a rear facing child
restraint in the right front passenger 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 the
airbag is off before using a rear-facing child
restraint in the right front seat position.
CAUTION: (Continued)
1-38

6. To tighten the belt, push down on the child restraint,
pull the shoulder portion of the belt to tighten the
lap portion of the belt and feed the shoulder belt back
into the retractor. If you are using a forward-facing
child restraint, you may nd it helpful to use your knee
to push down on the child restraint as you tighten the
belt. You should not be able to pull more of the belt
out of the retractor once the lock has been set.
7. Push and pull the child restraint in different
directions to be sure it is secure.
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.
Securing a Child Restraint in the
Right Front Seat Position
(Regular and Extended Cab)
(With Airbag Off Switch)
Your vehicle has a right front passenger airbag. There is
a switch on the instrument panel that you can use to turn
off the right front passenger’s frontal airbag. See the
following illustration. Your switch may vary slightly.
SeeAirbag Off Switch on page 1-70for more on this,
including important safety information and illustrations of
alternate switch designs.
{CAUTION:
A child in a rear-facing child restraint can be
seriously injured or killed if the passenger’s
airbag inates. This is because the back of the
rear-facing child restraint would be very close
to the inating airbag. Do not use a rear-facing
child restraint in this vehicle unless the
passenger’s airbag has been turned off.
CAUTION: (Continued)
