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:

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 indicators to remind you and your
passengers to buckle your safety belts. SeeSafety Belt
Reminder Light on page 3-59andPassenger Safety
Belt Reminder Light on page 3-60.

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 1-26.
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. Move the shoulder belt height adjuster to the height
that is right for you. Improper shoulder belt height
adjustment could reduce the effectiveness of the
safety belt in a crash. SeeShoulder Belt Height
Adjustment on page 1-20.
6. To make the lap part tight, pull up on the
shoulder belt.
7. This safety belt has a feature that will reduce the
tension of the safety belt on the occupant’s
shoulder if the vehicle is on. To set this feature,
gently pull on the belt, or lean forward and then sit
back. The belt will retract and rest lightly against
the occupant.
1-14

Right Front Passenger Position
To learn how to wear the right front passenger’s safety
belt properly, seeDriver Position on page 1-13.
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 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.
1-21

There is no top tether anchor in the right front
passenger’s 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 1-37if your 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 1-59. 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 1-2.
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 the vehicle
is running. SeePassenger Airbag Status Indicator
on page 3-61.2. 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.
1-47

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.
A thick layer of additional material such as a blanket,
or aftermarket equipment such as seat covers heaters
or massagers, located between the seat cushion and
the child restraint or small occupant, can affect how
the passenger sensing system operates. Remove
any additional material from the seat cushion before
reinstalling/securing the child restraint or small occupant.
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.Airbag System
Your vehicle has six airbags:
A frontal airbag for the driver and another frontal
airbag for the right front passenger.
A seat-mounted side impact airbag for the driver
and another for the right front passenger.
A roof-mounted side impact airbag for the driver
and passenger directly behind the driver.
A roof-mounted side impact airbag for the right front
passenger and the person seated directly behind
that passenger.
Frontal airbags are designed to help reduce the risk
of injury from the force of an inating airbag. But these
airbags must inate very quickly to do their job and
comply with federal regulations.
