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
Climate Controls in Section 3

Heated Seats
If your vehicle has 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.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 seats will be canceled after the ignition is
turned off. If you still want to use the heated seat feature
after you restart your vehicle, you will need to press
the heated seat button again.

Returning the 50/50 Split Bench Seat(s)
from a Tilted Position
To return the seat to the normal seating position,
do the following:
1. Open the liftgate to access the controls for the
50/50 seat.
2. Pull the lever labeled 3 toward you.
3. While still holding the lever 3 toward you, grasp the
top of the seat and pull it toward you slightly.
4. Let go of lever 3 and pull the seat completely down.5. Push down on the seat rmly. Try pulling it up
to make sure it is locked in place.
6. Pull up on the release lever labeled 1, located
on the rear of the seatback. Then pull up on the
seatback until it locks into the 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 push and pull on the seatback to be
sure it is locked.
7. Push and pull on the seatback to make sure it
is locked.

{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 3-37.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 1-47
orInfants and Young Children on page 1-50. 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 1-46.
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.
1-32

Rear Outside Passenger Positions
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
The positions next to the windows have lap-shoulder
belts. Here is how to wear a lap-shoulder belt 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.
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.

{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.
Even though the passenger sensing system is
designed to turn off the passenger’s frontal
airbag if the system detects a rear-facing child
restraint, 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. We recommend that
rear-facing child restraints be secured in the
rear seat, even if the airbag is off.
If you need to secure a forward-facing child restraint in
the right front seat position, move the seat as far
back as it will go before securing the forward-facing
child restraint. SeePower Seats on page 1-4orManual
Seats on page 1-3.
If your child restraint is equipped with the LATCH system,
seeLower Anchors and Tethers for Children (LATCH)
on page 1-58.There is no top tether anchor at the right front seating
position. Do not secure a child seat in this position
if a national or local law requires that the top tether be
anchored or if the instructions that come with the
child restraint say that the top tether must be anchored.
SeeLower Anchors and Tethers for Children (LATCH)
on page 1-58if the child restraint has a top tether.
You will be using the 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. Your vehicle has a right front passenger’s
frontal airbag. SeePassenger Sensing System
on page 1-82. General Motors recommends
that rear-facing child restraints be secured in a rear
seat, even if the airbag is off. If your child restraint
is forward-facing, move the seat as far back as it will
go before securing the child restraint in this seat.
SeePower Seats on page 1-4orManual Seats
on page 1-3.
When the passenger sensing system has turned off
the right front passenger’s frontal airbag, the off
indicator in the passenger airbag status indicator
should light and stay lit when you turn the ignition
to RUN or START. SeePassenger Airbag
Status Indicator on page 3-38.
2. Put the child restraint on the seat.
1-71

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 from the retractor
once the lock has been set.7. Push and pull the child restraint in different
directions to be sure it is secure.
8. If your vehicle has the passenger sensing system
and the airbag is off, the off indicator in the rearview
mirror will be lit and stay lit when the key is
turned to RUN or START.
If a child restraint has been installed and the on
indicator is lit, turn the vehicle off. Remove the child
restraint from the vehicle and reinstall the child restraint.
If after reinstalling the child restraint and restarting
the vehicle, the on indicator is still lit, check to make
sure that the vehicle’s seatback is not pressing the child
restraint into the seat cushion. If this happens, slightly
recline the vehicle’s seatback and adjust the seat
cushion if possible. Also make sure the child restraint is
not trapped under the vehicle head restraint. If this
happens, adjust the head restraint.
If the on indicator is still lit, secure the child in the
child restraint in a rear seat position in the vehicle and
check with your dealer.
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.
1-73

{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. 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 1-47orInfants and Young Children
on page 1-50.
There is an airbag
readiness light on the
instrument panel cluster,
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 3-38
for more information.
Where Are the Airbags?
The driver’s frontal airbag is in the middle of the
steering wheel.
