6. To tighten the belt, feed the shoulder belt back into
the retractor while you push down on the child
restraint. You may nd it helpful to use your knee to
push down on the child restraint as you tighten
the belt.
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.
Air Bag Systems
This part explains the frontal and side impact air bag
systems.
Your vehicle has six air bags:
A frontal air bag for the driver and another frontal
air bag for the right front passenger,
a seat mounted side impact air bag for the driver
and another for the right front passenger,
a roof-mounted side impact air bag for the driver
and passenger directly behind the driver, and
a roof-mounted side impact air bag for the right
front passenger and the person seated directly
behind that passenger.
Frontal air bags are designed to help reduce the risk of
injury from the force of an inating air bag. But these
air bags must inate very quickly to do their job
and comply with federal regulations.
1-50

{CAUTION:
Both frontal and side impact air bags inate
with great force, faster than the blink of an
eye. If you’re too close to an inating air bag,
as you would be if you were leaning forward, it
could seriously injure you. Safety belts help
keep you in position for air bag ination before
and during a crash. Always wear your safety
belt even with frontal air bags. The driver
should sit as far back as possible while still
maintaining control of the vehicle. Occupants
should not lean on or sleep against the door.
{CAUTION:
Anyone who is up against, or very close to,
any air bag when it inates can be seriously
injured or killed. Air bags 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 air bag
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,
see the part of this manual called “Older
Children” or “Infants and Young Children.”

Programmable Automatic
Door Locks
Your vehicle is programmed so that when the doors are
closed, the ignition is on and the shift lever is moved
out of PARK (P), all the doors will lock. The doors
will unlock every time you stop the vehicle and move
the shift lever back into PARK (P).
If someone needs to exit the vehicle once the doors are
locked, have that person use the manual lever or
power door lock switch. When the door is closed again,
it will not lock automatically. Use the manual lever or
the power door lock switch to lock the door.
The power door locks can be programmed through
prompts displayed on the Driver Information
Center (DIC). These prompts allow you to choose
various lock and unlock settings. For more information
on programming, seeDIC Vehicle Personalization
on page 3-73.
Rear Door Security Locks
Your vehicle is equipped with rear door security locks
that prevent passengers from opening the rear doors on
your vehicle from the inside.
The rear door security
locks are located on the
inside edge of each
rear door. You must
open the rear doors to
access them.
To use these locks, do the following:
1. Insert your key into the slot next to the rear door
security lock label and turn it to engage the lock.
2. Close the door.
3. Repeat the steps for the other rear door.
The rear doors on your vehicle cannot be opened from
the inside when this feature is in use.
2-10

When you want to open a rear door when the security
lock is on, do the following:
1. Unlock the door using the remote keyless entry
transmitter, the front door power lock switch or
by lifting the rear door manual lock.
2. Then open the door from the outside.
To cancel the rear door security lock, do the following:
1. Unlock the door and open it from the outside.
2. Insert your key into the slot next to the rear door
security lock label and turn it to disengage the lock.
3. Repeat the steps for the other lock.
The rear door locks will now work normally.Lockout Protection
If you press the power door lock switch when the key is
in the ignition and any door is open, all the doors will
lock and only the driver’s door will unlock. If you
close the doors, you can lock them using the remote
keyless entry transmitter. Be sure to remove the
key from the ignition when locking your vehicle.
The anti-lockout feature can be overridden by pressing
the lock button on the remote keyless entry transmitter
or by pressing the power lock switch a second time.
Leaving Your Vehicle
If you are leaving your vehicle, open the door, lock the
vehicle from the inside; then get out and close the door.

Theft-Deterrent Systems
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number of theft-deterrent
features, we know that nothing we put on it can make it
impossible to steal.
Theft-Deterrent System
The security light is
located on the instrument
panel cluster.
If the ignition is off and a door is open, the security light
will ash, reminding you to arm the theft-deterrent system.
To arm the system, do the following:
1. Open the door.
2. Lock the door using the remote keyless entry
transmitter or the power door lock switch. The
security light should come on and stay on.
3. Close all the doors. The security light should go off
within approximately 30 seconds.If a door or a liftgate is opened without a key or a
remote keyless entry transmitter, the horn will sound
and the lamps will ash for up to 30 seconds.
The theft-deterrent system won’t arm if you lock the
doors with a key or use the manual door lock.
It activates only if you use the remote keyless entry
transmitter or the power door lock.
To avoid activating the alarm by accident do the
following:The vehicle should be locked with the door key or
the manual door lock after the doors are closed if
you don’t want to arm the theft-deterrent system.
Always unlock a door with a key or use the remote
keyless entry transmitter. Pressing the unlock button
on the remote keyless entry transmitter disarms the
theft-deterrent system. Unlocking a door any other
way while the system is armed will activate the alarm
when a door or the liftgate is opened.
If you activate the alarm by accident, unlock the driver’s
door with your key. You can also turn off the alarm by
using the unlock button on the remote keyless entry
transmitter, or by starting the vehicle with a valid key.
2-17

Testing the Alarm
1. From inside the vehicle, roll down the window,
then get out of the vehicle, keeping the door open.
2. From outside of the vehicle, with the door open,
lock the vehicle using the power door lock switch
or the remote keyless entry transmitter and
close the door. Wait approximately 30 seconds until
the security light goes off.
3. Reach in and unlock the door using the manual
lock and open the door. The horn will sound and
the exterior lamps will ash.
You can turn off the alarm by unlocking the driver’s door
with your key, using the unlock button on the remote
keyless entry transmitter or by starting the car with
a valid key.
If the alarm does not sound when it should, check to
see if the horn works. The horn fuse may be blown.
To replace the fuse, seeFuses and Circuit Breakers on
page 5-103. If the fuse does not need to be replaced,
you may need to have your vehicle serviced.
To reduce the possibility of theft, always arm the
theft-deterrent system when leaving your vehicle.

2-18

Immobilizer Operation
Your vehicle is equipped
with a passive
theft-deterrent system.
The system works when you turn the key to ON.
The key uses a transponder that matches an immobilizer
control unit in your vehicle. The correct key will start
the vehicle.
Your vehicle has a special key that works with the
theft-deterrent system. There is a transponder in the
key head. If the key is ever damaged, you may not be
able to start your vehicle.When trying to start the vehicle, if the engine does not
start and the security light comes on, the key may
have a damaged transponder. Turn the ignition off and
try again.
If the engine still does not start, and the key appears to
be undamaged, try another ignition key. At this time,
you may also want to check the fuse. SeeFuses
and Circuit Breakers on page 5-103. If the engine still
does not start with the other key, your vehicle needs
service. If your vehicle does start, the rst key may be
faulty. See your dealer who can service the
theft-deterrent system to have a new key made.
It is possible for the theft-deterrent system decoder to
learn the transponder value of a new or replacement
key. Up to 10 additional keys may be programmed for
the vehicle. This procedure is for learning additional
keys only.
Canadian Owners:If you lose or damage your keys,
only a GM dealer can service the theft-deterrent system
to have new keys made. To program additional keys
you will require two current driver’s keys. You must add
a step to the following procedure. After Step 2, repeat
Steps 1 and 2 with the second current driver’s key.
Then continue with Step 3.
