Playing a Disc
To play a disc, gently insert the disc with the label side up
into the loading slot. The DVD player will continue loading
the disc and the player will automatically start, if the
vehicle is in RUN, ACCESSORY, or when RAP is active.
If a disc is already in the player, press the play/pause
button on the DVD player faceplate or on the remote
control.
Some DVDs will not allow fast forwarding or skipping
of the copyright information or the previews. Some
DVDs will begin playing after the previews have nished.
If the DVD does not begin to play the main title, refer
to the on-screen instructions.
Stopping and Resuming Playback
To stop playing a disc, press and release the stop button
on the DVD player faceplate or the remote control.
To resume playback, press the play/pause button on
the DVD player faceplate or the remote control.
The movie should resume play from where it was last
stopped, if the disc has not been ejected and the
stop button has not been pressed twice. If the disc has
been ejected or if the stop button has been pressed
twice, the disc will resume play at the beginning.
Ejecting a Disc
Press the eject button on the DVD player faceplate to
eject the disc. There is not an eject button on the remote
control.
If a disc is ejected from the player, but is not removed, the
DVD player will reload the disc after a short period of
time. The disc will be stored in the DVD player. The DVD
player will not resume play of the disc automatically.
Remote Control
To use the remote control, aim it at the transmitter
window below the video screen and press the desired
button. Direct sunlight or very bright light may affect the
ability of the RSE system to receive signals from the
remote control. If the remote control does not seem to
be working, the batteries may need to be replaced.
See “Battery Replacement” later in this section.
Objects blocking the line of sight may also affect the
function of the remote control.
Notice:Storing the remote control in a hot area or
in direct sunlight may damage it, and the repairs
would not be covered by your warranty. Keep
the remote control stored in a cool, dry place.
To extend the life of the batteries, the remote control
does not have a press and hold feature.

{CAUTION:
Snow can trap exhaust gases under your
vehicle. This can cause deadly CO (carbon
monoxide) gas to get inside. CO could
overcome you and kill you. You cannot see it
or smell it, so you might not know it is in your
vehicle. Clear away snow from around the
base of your vehicle, especially any that is
blocking your exhaust pipe. And check around
again from time to time to be sure snow does
not collect there.
Open a window just a little on the side of the
vehicle that is away from the wind. This will
help keep CO out.Run your engine only as long as you must. This saves
fuel. When you run the engine, make it go a little
faster than just idle. That is, push the accelerator
slightly. This uses less fuel for the heat that you get and
it keeps the battery charged. You will need a
well-charged battery to restart the vehicle, and possibly
for signaling later on with your headlamps. Let the
heater run for a while.
Then, shut the engine off and close the window almost
all the way to preserve the heat. Start the engine
again and repeat this only when you feel really
uncomfortable from the cold. But do it as little as
possible. Preserve the fuel as long as you can. To help
keep warm, you can get out of the vehicle and do
some fairly vigorous exercises every half hour or so until
help comes.

Replacing Brake System Parts
The braking system on a vehicle is complex. Its many
parts have to be of top quality and work well together if
the vehicle is to have really good braking. Your
vehicle was designed and tested with top-quality GM
brake parts. When you replace parts of your braking
system — for example, when your brake linings
wear down and you need new ones put in — be sure
you get new approved GM replacement parts. If you do
not, your brakes may no longer work properly. For
example, if someone puts in brake linings that are wrong
for your vehicle, the balance between your front and
rear brakes can change — for the worse. The braking
performance you have come to expect can change
in many other ways if someone puts in the wrong
replacement brake parts.
Battery
Your vehicle has a maintenance free battery. When it is
time for a new battery, get one that has the replacement
number shown on the original battery’s label. We
recommend an ACDelco
®replacement battery. See
Engine Compartment Overview on page 5-12for
battery location.
Warning:Battery posts, terminals and related
accessories contain lead and lead compounds,
chemicals known to the State of California to cause
cancer and reproductive harm. Wash hands after
handling.

Vehicle Storage
If you are not going to drive your vehicle for 25 days
or more, remove the black, negative (−) cable from
the battery. This will help keep your battery from
running down.
{CAUTION:
Batteries have acid that can burn you and gas
that can explode. You can be badly hurt if you
are not careful. SeeJump Starting on
page 5-42for tips on working around a battery
without getting hurt.
Also, for your audio system, seeTheft-Deterrent
Feature on page 3-99.
Jump Starting
If your battery has run down, you may want to use
another vehicle and some jumper cables to start your
vehicle. Be sure to use the following steps to do it safely.
{CAUTION:
Batteries can hurt you. They can be dangerous
because:
They contain acid that can burn you.
They contain gas that can explode or ignite.
They contain enough electricity to
burn you.
If you do not follow these steps exactly, some or
all of these things can hurt you.
5-42

Notice:Ignoring these steps could result in costly
damage to your vehicle that would not be covered
by your warranty.
Trying to start your vehicle by pushing or pulling it
will not work, and it could damage your vehicle.
1. Check the other vehicle. It must have a 12-volt
battery with a negative ground system.
Notice:If the other vehicle’s system is not a 12-volt
system with a negative ground, both vehicles can
be damaged. Only use vehicles with 12-volt systems
with negative grounds to jump start your vehicle.
2. Get the vehicles close enough so the jumper cables
can reach, but be sure the vehicles are not touching
each other. If they are, it could cause a ground
connection you do not want. You would not be able
to start your vehicle, and the bad grounding
could damage the electrical systems.
To avoid the possibility of the vehicles rolling, set
the parking brake rmly on both vehicles involved in
the jump start procedure. Put an automatic
transmission in PARK (P) or a manual transmission
in NEUTRAL before setting the parking brake.Notice:If you leave your radio or other accessories
on during the jump starting procedure, they could
be damaged. The repairs would not be covered
by your warranty. Always turn off your radio and
other accessories when jump starting your vehicle.
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter or the accessory power outlets. Turn off
the radio and all lamps that are not needed. This
will avoid sparks and help save both batteries. And
it could save the radio!
