Anchor brackets for the rear outside seat positions are
located on the floor in the cargo area of your vehicle.
Don't use the rear set of tie
-down brackets. Anchor the
top strap to the closest bracket on the same side of the
vehicle as the child restraint.
Once you have the top strap anchored, you'll be ready to
secure the child restraint itself.
Securing a Child Restraint in a Rear
Outside Seat Position
You'll be using the lap-shoulder belt. See the earlier
part about the top strap if the child restraint has one.
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. Put the restraint on the seat.
2. 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.
If the shoulder belt goes in front of the child's face or
neck, put it behind the child restraint.

5. To tighten the belt, feed the shoulder belt back into
the retractor while you push down on the child
restraint. If you're using a forward
-facing child
restraint, you may find it helpful to use your knee to
push down on the child restraint as you tighten
the belt.6. 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.
Center Seat Position
Don't use child restraints in this position. The restraints
won't work properly.

1-45 Securing a Child Restraint in the Right
Front Seat Position
Your vehicle has a right front passenger air bag. Never
put a rear
-facing child restraint in this seat. Here's why:
CAUTION:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger's air bag inflates. This is because the
back of the rear
-facing child restraint would be
very close to the inflating air bag. Always secure
a rear
-facing child restraint in the rear seat.
Although a rear seat is a safer place, you can secure a
forward
-facing child restraint in the right front seat.
You'll be using the lap
-shoulder belt. See the earlier
part about the top strap if the child restraint has one.
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. Because your vehicle has a right front passenger air
bag, always move the seat as far back as it will go
before securing a forward
-facing child restraint.
(See ªSeatsº in the Index.)
2. Put the restraint on the seat.

6. To tighten the belt, feed the shoulder belt back into the
retractor while you push down on the child restraint.
You may find 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.
Larger Children
Children who have outgrown child restraints should
wear the vehicle's safety belts.
If you have the choice, a child should sit next to a
window so the child can wear a lap
-shoulder belt and
get the additional restraint a shoulder belt can provide.

NOTICE:
When replacing the battery, use care not to
touch any of the circuitry. Static from your
body transferred to these surfaces may damage
the transmitter.
To replace the battery in the remote keyless entry transmitter:
1. Insert a dime in the slot between the covers of the
transmitter housing near the key ring hole. Remove
the bottom by twisting the dime.
2. Remove and replace the battery with a three
-volt
CR2032 or equivalent battery, positive (+) side up.
3. Align the covers and snap them together.
4. Resynchronize the transmitter.
5. Check the operation of the transmitter.
Resynchronization
Resynchronization may be necessary due to the security
method used by this system. The transmitter does not
send the same signal twice to the receiver. The receiver
will not respond to a signal it has been sent previously.
This prevents anyone from recording and playing back
the signal from the transmitter.
To resynchronize your transmitter, stand close to your
vehicle and press and hold the LOCK and UNLOCK
buttons on the transmitter at the same time for seven
seconds. The door locks should cycle to confirm
synchronization. If the locks do not cycle, see your
dealer for service.

2-10 Emergency Release for Opening Liftgate
1. Peel back or slit the carpet locally to expose the
access hole in the trim panel.
2. Use a thin screwdriver
to reach through the
access holes in both
the trim panel and the
hardware cover.
3. Pry the release lever toward the passenger's side
until the glass latch pops open.
4. Reattach the carpet securely.
Remote Liftglass Release
This button to the right of
the steering wheel on the
instrument panel allows
you to release the liftglass
from inside the vehicle.
Your shift lever must be in PARK (P) or NEUTRAL (N)
for the release to work.
Theft
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. However, there are ways you
can help.

2-11 Key in the Ignition
If you leave your vehicle with the keys inside, it's an
easy target for joy riders or professional thieves
-- so
don't do it.
When you park your vehicle and open the driver's door,
you'll hear a chime reminding you to remove your key
from the ignition and take it with you. Always do this.
Your steering wheel will be locked, and so will your
ignition and transmission. Also remember to lock
the doors.
Parking at Night
Park in a lighted spot, close all windows and lock your
vehicle. Remember to keep your valuables out of sight.
Put them in a storage area, or take them with you.
Parking Lots
If you park in a lot where someone will be watching
your vehicle, it's best to lock it up and take your keys.
But what if you have to leave your ignition key? What if
you have to leave something valuable in your vehicle?

Put your valuables in a storage area, like your
glove box.

If your vehicle has a remote keyless entry system,
take the transmitter with you.

Lock all the doors except the driver's.
Content Theft-Deterrent
Your vehicle is equipped with a Content Theft-Deterrent
alarm system.
With this system, the
SECURITY light will
flash as you open the
door (if your ignition
is off).
This light reminds you to activate the theft
-deterrent
system. Here's how to do it:
1. Open the door.
2. Lock the door with the power door lock switch or the
remote keyless entry transmitter. The SECURITY
light should come on and stay on.
3. Close all doors. The SECURITY light should go
off after approximately 30 seconds. The alarm is not
armed until the SECURITY light goes off.
If a door is opened without the key or the remote
keyless entry transmitter, the alarm will go off. Your
vehicle's high
-beam headlamps will flash and the horn
will sound for 110 seconds, then will turn off to save
the battery power.
ProCarManuals.com

2-12
Remember, the theft-deterrent system won't activate if
you lock the doors with a key or use the manual door
lock. It activates only if you use a power door lock
switch with the door open, or with the remote keyless
entry transmitter. You should also remember that you
can start your vehicle with the correct ignition key if the
alarm has been set off.
Here's how to avoid setting off the alarm by accident:

If you don't want to activate the theft
-deterrent
system, the vehicle should be locked with the door
key after the doors are closed.

Always unlock a door with a key, or use the remote
keyless entry transmitter. Unlocking a door any other
way will set off the alarm.
If you set off the alarm by accident, unlock any door
with the key. You can also turn off the alarm by pressing
UNLOCK on the remote keyless entry transmitter.
The alarm won't stop if you try to unlock a door any
other way.
Testing the Alarm
The alarm can be tested by following these steps:
1. From inside the vehicle, lower the driver's window
and open the driver's door.
2. Activate the system by locking the doors with the
power door lock switch while the door is open, or
with the remote keyless entry transmitter.
3. Get out of the vehicle, close the door and wait for
the SECURITY light to go out.
4. Then reach in through the window, unlock the
door with the manual door lock and open the door.
This should set off the alarm.
If the alarm does not sound when it should but the
vehicle's high
-beam headlamps flash, check to see if the
horn works. The horn fuse may be blown. To replace the
fuse, see ªFuses and Circuit Breakersº in the Index.
If the alarm does not sound or the vehicle's high
-beam
headlamps do not flash, the vehicle should be serviced
by an authorized service center.

Passlock
Your vehicle is equipped with the Passlock
theft
-deterrent system.
Passlock is a passive theft
-deterrent system. Passlock
enables fuel if the ignition lock cylinder is turned with a
valid key. If a correct key is not used or the ignition lock
cylinder is tampered with, fuel is disabled.
During normal operation, the SECURITY light will go
off approximately five seconds after the key is turned to
the RUN ignition position.
If the engine stalls and the SECURITY light flashes,
wait about 10 minutes until the light stops flashing
before trying to restart the engine. Remember to release
the key from START as soon as the engine starts.
If the engine does not start after three (3) tries, the
vehicle needs service.
If the engine is running and the SECURITY light comes
on, you will be able to restart the engine if you turn the
engine off. However, your Passlock system is not working
properly and must be serviced by your dealer. Your vehicle
is not protected by Passlock at this time. You may also
want to check the fuse (see ªFuses and Circuit Breakersº
in the Index). See your dealer for service.
In an emergency, call the GMC Roadside Assistance
Center at 1
-800-GMC-8782.
New Vehicle ªBreak-Inº
NOTICE:
Your vehicle doesn't need an elaborate ªbreak-in.º
But it will perform better in the long run if you
follow these guidelines:

Keep your speed at 55 mph (88 km/h) or
less for the first 500 miles (805 km).

Don't drive at any one speed
-- fast or
slow
-- for the first 500 miles (805 km).
Don't make full
-throttle starts.

Avoid making hard stops for the first
200 miles (322 km) or so. During this time
your new brake linings aren't yet broken
in. Hard stops with new linings can mean
premature wear and earlier replacement.
Follow this breaking
-in guideline every
time you get new brake linings.

Don't tow a trailer during break
-in.
See ªTowing a Trailerº in the Index for
more information.
