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

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.

Your vehicle has a light
that comes on as a
reminder to buckle up. See
Safety Belt Reminder
Light on page 3-34.
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!Why Safety Belts Work
When you ride in or on anything, you go as fast as
it goes.
Take the simplest vehicle. Suppose it is just a seat on
wheels.

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 1-30.
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.5. To make the lap part tight, pull up on the
shoulder belt.
1-17

Lap-Shoulder Belt
All rear seat 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 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 1-30.
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 up on the
shoulder part.

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.
Even though the passenger sensing system or
airbag off switch are designed to turn off the
passenger’s frontal airbag under certain
conditions, 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
CAUTION: (Continued)
CAUTION: (Continued)
recommends that rear-facing child restraints
be transported in vehicles with a rear seat that
will accommodate a rear-facing child restraint,
whenever possible.
If you need to 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:
A child in a child restraint in the center front
seat can be badly injured or killed by the right
front passenger’s airbag if it inates. Never
secure a child restraint in the center front seat.
It is always better to secure a child restraint in
the rear seat.
Do not use child restraints in the center front seat
position. The restraints will not work properly.
1-41

Your switch may vary slightly. SeeAirbag Off Switch on
page 1-78for 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.
Even though the airbag off switch is designed
to turn off the passenger’s frontal 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. We recommend that rear-facing child
restraints be transported in vehicles with a
rear seat that will accommodate a rear-facing
child restraint, whenever possible.
If you need to secure a forward-facing child
restraint in the right front static seat or the
right front bench seat, always move the
passenger seat as far back as it will go. United States
Canada

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 the airbag is off before using a rear-facing
child restraint in the right front seat position. If
you secure a forward-facing child restraint in
the right front seat, always move the right front
passenger seat as far back as it will go.
A rear seat is a safer place to secure a forward facing
child restraint. SeeWhere to Put the Restraint on
page 1-40. 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 a
forward-facing child restraint. SeeManual Seats on
page 1-3orPower Seats on page 1-4.
{CAUTION:
If the airbag readiness light in the instrument
panel cluster ever comes on when you have
turned off the airbag, 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, have the vehicle serviced promptly.
Until you have the vehicle serviced, 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). SeeAirbag Off Switch on
page 1-78.
If your child restraint is equipped with the LATCH
system, seeLower Anchors and Tethers for Children
(LATCH) on page 1-42.
1-61

If your vehicle has a rear seat, 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 1-42if
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. SeeAirbag Off Switch on page 1-78. If your
child restraint is forward-facing, move the seat as far
back as it will go before securing the restraint in this
seat. SeeManual Seats on page 1-3orPower Seats
on page 1-4. If you need to use a rear-facing child
restraint in this seat, make sure the airbag is off once
the child restraint has been installed.
When the airbag off switch has turned off the right
front passenger’s frontal airbag, the off indicator
in the airbag off light should light and stay lit when
you turn the ignition to RUN or START. See
Airbag Off Light on page 3-35.2. Put the child 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.
