Content Theft-Deterrent
Your vehicle is equipped with a Content Theft-Deterrent
alarm system.
With this system, the
SECURITY message will
flash as you open the door
(if your ignition is off).
This message 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
message should come on and stay on. If you're using
the remote keyless entry transmitter, the door does
not need to be open.
3. Close all doors. The SECURITY message should go
off after approximately 15 seconds. The alarm is not
armed until the SECURITY message goes off.If a door is opened without the key or the remote keyless
entry transmitter, the alarm will go off. Your vehicle's
headlamps will flash and the horn will sound for about
two minutes, 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 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 the system has
been armed.
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 or by
placing the key in the ignition and turning it to START.

2-26
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 message 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 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 to the engine 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.
If the engine stalls and the SECURITY message flashes,
wait 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 is running and the SECURITY message
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 GM Roadside Assistance
Center. See ªRoadside Assistanceº in the Index.

2-66
Top-Box Storage
Your vehicle is equipped with Top-Box Storage units on
both sides of the vehicle. The passenger side Top Box
contains the tools you will need to change a flat tire.
Use the ignition/door key to unlock the Top Box lid if it
is locked. Press the key cylinder button and swing the
lid open. Turn on the cargo lamps if you need more
light inside the Top Boxes. See ªCargo Lampsº in
the Index for more information on cargo lamps.
Use the ignition/door key to lock the Top Boxes.
Tonneau Cover (If Equipped)
CAUTION:
Improperly stored tonneau cover component(s)
could be thrown about the vehicle during a
collision or sudden maneuver. You or others
could be injured. If you remove the cover, bows
and rails always store them properly in the cargo
area. When you put them back, always be sure
that they are securely reattached.
If your vehicle is equipped with a tonneau cover, it will
come installed from the factory. The main components
of the tonneau cover are the following:

2-72
5. Stow both bows and the front and rear rails in the
storage bag as shown. When all components of the
tonneau cover are secured in the bag properly, zip
the bag shut.Reverse the procedure to reinstall the tonneau cover
using the following suggestions:

When reinstalling the front rail, start by holding
the back edge of the rail (edge nearest you) up and
then twisting the back edge down while pushing it
into place.

Both bows are the same size and
therefore interchangeable.

When placing the bows in the side rails, it is
easiest to place the spring
-loaded bow end in first.

2-73

When placing the
bows, locate the small
notches in the side
rails. These notches
receive the tang on the
bow ends and help the
bows seat into place.

When reinstalling the tonneau cover, start at the front
(near the cab). Place the plastic lip into the front rail
then the rear rail and finish with the side rails.
To clean the tonneau cover, use mild soap and water.
If necessary, use a soft bristle brush to remove dirt
trapped in the grain of the material.Cargo Cover Panels (If Equipped)
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 in its proper
position in the cargo panel storage bag with the
bag securely attached to the cargo tie downs.
When you put it back, always be sure that it is
securely reattached.
NOTICE:
Each cargo cover is designed to support 250 lbs.
(113 kg) each on top of them. Exceeding the weight
limit can damage the cargo covers. This damage
would not be covered by your vehicle's warranty.
Your vehicle may be equipped with a three-piece cargo
cover system. The cargo panels can be removed and
stored in the cargo area of the vehicle with the cargo
panel storage bag.

Cargo Panel Storage System
The three cargo panels can be stored on either the
driver's or passenger's side of the cargo box using the
storage bag. To store the panels, do the following:1. Secure the storage
bag in the cargo
storage area by
attaching the
four clips on the
cargo bag to the
tie
-down locations
on either side of
the storage area.
It is very important that you use the storage bag to
restrain the cargo panels during driving.
Before storing the cargo panels, be sure that the
latches are in the closed (locked) position. The latches
are in the closed (locked) position when they are
parallel to the front and back edge of the panel.

6. Snug both straps on the bag by pulling on the free
end of the straps.7. Close both top and bottom mechanisms at the center
of the bag (bag should now be tightly secured).

2-87
Cargo Area Floor Drains
Your vehicle also has four cargo-area floor drains
located under the cargo mat near the sides of the cargo
area. These drains should be cleaned periodically to
allow water to exit the cargo area.
The cargo mat has cutouts for the drains. You can flush
the drains through the cutouts, but if the cargo area is
extremely dirty you can lift up the edges of the cargo
floor mat (or take the whole mat out) and flush the
drains with water.
Cargo Tie Downs
There are eight cargo tie downs in the rear cargo area.
You can use these to strap cargo in.
The tie downs are also used to secure the cargo cover
panel storage bag or the tonneau cover storage bag
if your vehicle is equipped with either. For more
information see ªCargo Cover Panelsº and ªTonneau
Coverº in the Index.

2-88
Luggage Carrier
You can load things on top of your vehicle with this feature.
The luggage carrier has slats and siderails attached to the
roof and crossrails which can be moved back and forth
to help secure cargo. Tie the load to the siderails or
siderail supports.
NOTICE:
Loading cargo that weighs more than 200 lbs.
(90.6 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. Load your cargo so that it rests on the
slats and does not scratch or damage the vehicle.
Put the cargo against the siderails and fasten it
securely to the luggage carrier.
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 leaving,
check now and then to make sure the luggage and cargo
are still securely fastened.Be sure the cargo is properly loaded.

If small heavy objects are placed on the roof cut a
piece of 3/8 inch plywood to fit inside the crossrails
and siderails to spread the load. If plywood is used,
tie it to the siderail supports.

Tie the load to the crossrails or the siderail supports.
Use the crossrails only to keep the load from sliding.
To move the crossrails, pull out on the latch release
handle at each end. Slide the crossrail to the desired
position balancing the force side to side. Push the
release handle back into the latched position and
slide the crossrail back and forth slightly to be sure
the latch snaps securely into place.

If you need to carry long items, move the
crossrails as far apart as they will go. Tie the load
to the crossrails and the siderails or siderail supports.
Also tie the load to the bumpers. Do not tie the load
so tightly that the crossrails or siderails are damaged.

After moving a crossrail, be sure it is securely locked
into the siderail.
Your vehicle has a Center High
-Mounted Stoplamp
(CHMSL) located above the rear glass.
If items are loaded on the roof of the vehicle, care should
be taken not to block or damage the CHMSL unit.
