Cargo Security Shade
You can use the cargo security shade 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.
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 four cargo tie
downs in the rear that allow
you to
strap cargo in and
keep it from moving inside
the vehicle.

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.
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
Tie the load to the tie down (at either end of the
crossrails). When loading cargo directly on the
roof panel, use the crossrails to keep the load
from shifting.
not recommended.
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.
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.

NOTICE:
Loading cargo that weighs more than 200 Ibs.
(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 “Loading Your Vehicle“
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.
Ashtrays and Cigarette Lighter
The ashtray is located in the center floor console, in
front
of the shift lever. Flip the cover to expose
the ashtray.
NOTICE:
Don’t put papers and other things that burn into
your ashtray.
If you do, cigarettes or other
smoking materials could set them on fire
causing damage.
To remove the front ashtray, pull the bin upward.
The lighter is located
in the instrument panel below the
climate controls.
To use the lighter, press it in all the
way, and let
go. When it’s ready, it will pop back
by itself.

Training a Garage Opener with a “Rolling
Code” Feature
If you programmed the universal transmitter, but the
garage door will not open, and
if your garage door opener
was manufactured after
1995, your garage door may have
a security feature that changes the “code” of your garage
door opener every time it is opened or closed.
To determine if your garage door opener has this
“rolling code” feature, press the appropriate button on
the universal transmitter that was programmed.
If the
red light flashes rapidly for one to two seconds, then
turns solid, your garage door opener has this feature.
To program a garage door opener with the rolling code
feature, do the following:
1. Program your hand-held transmitter to the universal
transmitter by following the steps provided under
“Programming the Transmitter” earlier in
this section.
2.
3.
4.
5.
6.
Remove the cover panel from the garage door
opener receiver.
It is located near the garage door
opener motor.
Locate the training button on the garage door opener
receiver. The exact location and color will vary
among brands.
Press the training button on the garage door opener
receiver for one to two seconds.
Return to your vehicle and press the programmed
button on the universal transmitter
until the red light
flashes rapidly (about two seconds).
Release the button, then press it again to confirm it
was programmed
to the garage door opener receiver.
You may now use either the universal transmitter or the
hand-held transmitter to open your garage door.

Understanding Radio Reception
AM
The range for most AM stations is greater than for FM,
especially at night. The longer range, however, can
cause stations to interfere with each other. AM can pick
up noise from things like storms and power lines. Try
reducing the treble to reduce this noise
if you ever get it.
FM Stereo
FM stereo will give you the best sound, but FM signals
will reach
only about 10 to 40 miles (1 6 to 65 km). Tall
buildings or hills can interfere with
FM signals, causing
the sound to come and go.
Tips About Your Audio System
Hearing damage from loud noise is almost undetectable
until it is too late. Your hearing can adapt to higher
volumes
of sound. Sound that seems normal can be loud
and harmful to your hearing. Take precautions by
adjusting the volume control on your radio to a safe
sound level before your hearing adapts to
it.

Off-Road Driving with Your GM
Four-Wheel-Drive Vehicle
Also, see "Anti-Lock Brakes" in the Index.
Off-road driving can be great fun. But
it does have some
definite hazards. The greatest of these is the
terrain itself.
"Off-roading" means you've left the great North
American road system behind. Traffic lanes aren't
marked. Curves aren't banked. There are no road signs.
Surfaces can be slippery, rough,
uphill or downhill. In
short, you've gone right back to nature.
Off-road driving involves some new skills. And that's
why it's very important that
you read this guide. You'll
find many driving tips and suggestions. These will help
make
your off-road driving safer and more enjoyable.
Before You Go Off-Roading
There are some things to do before you go out. For
example, be sure to have all necessary maintenance and
service work done. Check to make sure all underbody
shields
(if so equipped) are properly attached. Be sure
you read all the information about your
four-wheel-drive vehicle
in this manual. Is there enough
fuel? Is the spare tire fully inflated'? Are the fluid levels
up where they should be? What are the local
laws that
apply to off-roading where you'll be driving?
If you
don't know, you should check with
law enforcement
people
in the area. Will you be on someone's private
land'?
If so. be sure to get the necessary permission.
Loading Your Vehicle for Off-Road Driving
There are some important things to remember about
how to load your vehicle.
0 The heaviest things should be on the load floor and
forward of
your rear axle. Put heavier items as far
forward as you can.
Be sure the load is secured properly, so driving on
the off-road terrain doesn't toss things around.

Cargo on the load floor piled higher than
the seatbacks can be thrown forward
during a sudden stop.
You or your
passengers could be injured. Keep cargo
below the top
of the seatbacks.
Unsecured cargo on the load floor can be
tossed about when driving over rough
terrain. You or your passengers can be
struck by flying objects. Secure the
cargo properly.
Heavy loads on the roof raise the vehicle’s
center of gravity, making it more likely to
roll
over. You can be seriously or fatally
injured
if the vehicle rolls over. Put heavy
loads inside the cargo area, not on the
roof.
Keep cargo in the cargo area as far forward
and low as nossible.
You’ll find other important information in this manual.
See “Vehicle Loading,” “Luggage Carrier” and “Tires”
in the Index.
Environmental Concerns
Off-road driving can provide wholesome and satisfying
recreation. However,
it also raises environmental
concerns.
GM recognizes these concerns and urges
every off-roader to follow these basic rules for
protecting the environment:

Always use established trails, roads and areas that
have been specially set aside for public off-road
recreational driving; obey all posted regulations.
Avoid any driving practice that could damage me
environment
-- shrubs, flowers, trees, grasses -- or
disturb wildlife (this includes wheel-spinning,
breaking down trees or unnecessary driving througn
streams or over soft ground).
Always carry
a litter bag . . . make sure all refuse is
removed from any campsite before leaving.
Take extreme care with open fires (where permitted),
camp stoves and lanterns.
Never park your vehicle over dry grass or other
combustible materials that could catch fire from the
heat
of the vehicle’s exhaust system.
