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:

Power Lumbar
Your vehicle’s seats have power lumbar.
You can increase or
decrease lumbar support
in an area of the lower
seatback with this control,
located on the outboard
sides of the front seat(s).
To increase support, press and hold the front of the
control. To decrease support, press and hold the rear of
the control. Let go of the control when the lower
seatback reaches the desired level of support.
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 2-63for more information.
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.

Rear Seats
Heated Seats
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 cushion, 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 is operating.
The heated rear seats will shut off automatically when
the ignition is turned off.
60/40 Split Bench Seat
The 60/40 split bench seats can be folded to give you
more cargo space.
Folding the Seatbacks
The seatbacks (SUV only) are equipped with rearward
folding head restraints. When the seatback is being
folded down, the head restraint will automatically
fold rearward.
To fold the rear seat, do the following:
1. Make sure that nothing is under or in front of
the seat.
2. Pull up on the strap
loop located at the rear
of the seat cushion
and pull the seat
cushion up and fold
it forward.
3. Pull the seatback forward and fold it down until it
is at.
If the seatback cannot fold at because it interferes
with the cushion, try moving the front seat forward
and/or bringing the front seatback more upright.
4. Repeat the steps for the other half of the 60/40 split
bench seat.

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.
5. Pull up on the release
lever labeled 1 and
then pull up on
the seatback until the
seatback locks into
the upright position.

Your vehicle has a light
that comes on as a
reminder to buckle up. See
Safety Belt Reminder
Light on page 3-31.
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.
1-15

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 1-32
orInfants and Young Children on page 1-35. 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.
1-19

Right Front Passenger Position
To learn how to wear the right front passenger’s safety
belt properly, seeDriver Position on page 1-19.
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 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 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.
1-27

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 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, 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 on page 1-65andAirbag
Readiness Light on page 3-32for more on this,
including important safety information.
1-55

{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 1-32andInfants
and Young Children on page 1-35.
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 3-32
for more information.
Where Are the Airbags?
The driver’s airbag is in the middle of the
steering wheel.
