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.
Endgate-Mounted Spare
If your vehicle has an endgate-mounted spare tire
carrier, you must move the carrier arm out of the way
to open the glass.
Here's how to move the arm:

Content Theft-Deterrent (If Equipped)
Your vehicle may be 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. Lock the door with the power door lock switch
(door must be open) or with the remote keyless
entry transmitter (door can be open or closed).
The SECURITY light should come on and stay on.
2. 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 keyless entry
transmitter, the alarm will go off. Your vehicle's headlamps
will flash and the horn will sound for 110 seconds, then will
turn off to save the battery power.
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 keyless entry
transmitter (door can be open or closed). 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 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 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 keyless entry transmitter (with the door
open or closed).
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 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 headlamps
do not flash, the vehicle should be serviced by a dealer.
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 RUN.
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 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.

2-70
Cargo Cover (If Equipped)
If your vehicle has a cargo cover, you can use it to cover
items in the cargo area of your vehicle.
Grasp the handle and unroll the cover. Latch the posts
into the sockets on the inside trim panel on the
passenger's side of the vehicle to secure it.
CAUTION:
An improperly stored cargo cover could be
thrown about the vehicle during a collision
or sudden maneuver. You or others could be
injured. If you remove the cover, always store it
outside of the vehicle. When you put it back,
always be sure that it is securely reattached.
Cargo Tie Downs
There are five cargo tie
downs in the rear of your
vehicle that allow you to
strap cargo in and keep it
from moving.
Rear Convenience System (If Equipped)
CAUTION:
If the convenience system isn't secured properly,
it can move around in a collision or sudden stop.
People in the vehicle could be injured. Be sure to
secure the convenience system properly.

2-72
There are two cutouts (E) for the rear cargo tie-downs
located near the liftgate/endgate sill. In order to access
the rear cargo tie
-downs, the cutouts must be removed.
You will also find a soda pop/gallon jug holder (D) on
the passenger side of the convenience system. Some
vehicles do not have this feature, but instead include a
smaller storage area.
To remove the entire convenience system,
do the following:
1. Remove the convenience net if it is in place.
See ªConvenience Netº in the Index for more
information. You may also want to remove the
partitions (C) and fold the collapsible dividers (A)
to make the convenience system easier to handle.
2. Grasp the sides of the convenience system and push
the sides together while sliding the unit out until it
clears the sides of the liftgate/endgate opening.
To reinstall the convenience system, reverse the
removal procedure.
Luggage Carrier (Option)
CAUTION:
If you try to carry something on top of your
vehicle that is longer or wider than the luggage
carrier
-- like paneling, plywood, a mattress,
and so forth
-- the wind can catch it as you
drive along. This can cause you to lose control.
What you are carrying could be violently torn
off, and this could cause you or other drivers
to have a collision, and of course damage your
vehicle. You may be able to carry something like
this inside. But, never carry something longer
or wider than the luggage carrier on top of
your vehicle.
The luggage carrier has slats, side rails and crossrails
attached to the roof to secure cargo. The adjustable tie
downs, at either end of the crossrails, should be used to
secure loads to the luggage carrier.

2-73
Use GM accessory racks that are compatible with
your luggage carrier for transporting sports equipment.
These are available through your GM dealer.
You can adjust the crossrails to handle loads of various
sizes. Just loosen the slider knobs at each end of the
crossrail and move them to where you want them.
Make sure both sides of the crossrails are even,
then tighten the slider knobs.
Be sure the cargo is properly loaded.
Follow these guidelines:

Carrying small, heavy loads on the roof is
not recommended.

Tie the load to the tie downs (at either end of
the crossrails). When loading cargo directly on
the roof panel, use the crossrails to keep the load
from shifting.

If you need to carry long items, move the crossrails
as far apart as possible. Tie the load to the tie downs
provided. Also tie the load to the bumpers. Do not
tie the load so tightly that the crossrails or side rails
are damaged.
NOTICE:
Loading cargo that weighs more than 200 lbs.
(91 kg) on the luggage carrier may damage your
vehicle. When you carry large things, never let
them hang over the rear or the sides of your
vehicle. When loading cargo on the roof panel,
be sure it rests on the slats and does not scratch
or damage the vehicle.
Put the cargo against the side rails and fasten it
securely to the luggage carrier. Put the main
weight as far forward as you can and move the
rear crossrail forward as far as possible to keep
the load from shifting.
Don't exceed the maximum vehicle capacity when loading
your vehicle. For more information on vehicle capacity
and loading, see ªLoading Your Vehicleº in the Index.
To prevent damage or loss of cargo as you're driving,
check now and then to make sure the luggage carrier and
cargo are still securely fastened.
