CD Changer
The compact disc changer plays up to six standard size
CDs continuously. Individual CDs may be loaded or
ejected into or from any position.
A green light on each numbered button indicates a CD
is loaded in the respective position. An amber light
on a numbered button indicates that a CD is playing.
When loading CDs, the loading slot indicators turn
amber to indicate that the player is ready
to accept a
CD. CDs can be loaded or ejected with the radio or the
ignition being on or
off.
You must load CDs with the label side up. If you do not,
the player will automatically eject the CDs.
Notice: Loading CDs with adhesive labels will
damage the player.
To load a CD, perform the following steps:
1. Press the LOAD button. Available positions Will
blink amber.
2. Select a position by pressing the desired numbered
button with the amber blinking light.
If a button is
not pressed within five seconds, the changer will go
to the lowest available position.
3. Load the CD when the loading slot indicators turn
amber. An internal door will open allowing a single
CD
to be inserted into the changer. After
approximately 10 seconds the changer will be ready
to play.
TO load two or more CDs, perform the
following steps:
1. Press and hold the LOAD button. The first CD will
be loaded into the lowest numbered empty position.
2. Load a single CD when the loading slot indicators
turn amber. After about 10 seconds the changer will
cycle to the next available position.
the desired positions.
If you do not wish to load all
of the positions, you can cancel the load all
function by pressing a button with a green flashing
indicator light or wait 20 seconds for the changer
to time out.
3. Repeat Step 2 until all CDs are loaded into all of

For best results, use a scrubbing action, non-abrasive
cleaning cassette with pads which scrub the tape
head as the hubs of the cleaner cassette turn. The
recommended cleaning cassette is available through
your dealer
(GM Part No. 12344789).
The cut tape detection feature of your cassette tape
player may identify the cleaning cassette as a damaged
tape, in error. To prevent the cleaning cassette from
being ejected, use the following steps:
1.
2.
3.
4.
5.
Turn the ignition on.
Turn the radio
off.
Press and hold the CD TAPE button for five
seconds. The tape symbol on the display will flash
for two seconds.
Insert the scrubbing action cleaning cassette.
Eject the cleaning cassette after the manufacturer’s
recommended cleaning time.
After the cleaning cassette is ejected, the cut tape detection feature will be active again.
You may also choose a non-scrubbing action, wet-type
cleaner which uses a cassette with a fabric belt
to
clean the tape head. This type of cleaning cassette will
not eject on its own. A non-scrubbing action cleaner
may not clean as thoroughly as the scrubbing type
cleaner. The use of a non-scrubbing action, dry-type
cleaning cassette is not recommended. After
you clean the player, press and hold the EJECT
button for five seconds to reset the CLN indicator.
The radio will display
--- to show the indicator was reset.
Cassettes are subject
to wear and the sound quality
may degrade over time. Always make sure the cassette
tape is in good condition before you have your tape
player serviced.
Care of Your CDs and DVDs
Handle discs carefully. Store them in their original cases
or other protective cases and away from direct sunlight
and dust. If the surface of a disc is soiled, dampen
a clean, soft cloth in a mild, neutral detergent solution
and clean it, wiping from the center to the edge.
Be sure never
to touch the side without writing when
handling discs. Pick up discs by grasping the outer
edges or the edge of the hole and the outer edge.
Care of Your CD Changer
The use of CD lens cleaner discs is not advised, due to
the risk of contaminating the lens
of the CD optics
with lubricants internal
to the CD mechanism.

0 Do not get too close to the vehicle you want to
pass while you’re awaiting an opportunity. For
one thing, following
too closely reduces your area
of vision, especially if you’re following a larger
vehicle.
Also, you won’t have adequate space if the
vehicle ahead suddenly slows or stops. Keep
back a reasonable distance.
When it looks like a chance to pass is coming up,
start
to accelerate but stay in the right lane and
don’t get
too close. Time your move so you will be
increasing speed as the time comes
to move
into the other lane. If the way is clear
to pass, you
will have a “running start” that more than makes
up for the distance you would lose by dropping
back. And
if something happens to cause you to
cancel your pass, you need only slow down
and drop back again and wait for another
opportunity.
If other vehicles are lined up to pass a slow vehicle.
wait your turn. But take care that someone isn’t
trying
to pass you as you pull out to pass the slow
vehicle. Remember to glance over your shoulder
and check the blind spot.
Check your mirrors, glance over your shoulder and
start your left lane change signal before moving out
of the right lane
to pass. When you are far
enough ahead of the passed vehicle
to see its front
in your inside mirror, activate your right lane
change signal and move back into the right lane.
(Remember that
if your right outside mirror is
convex, the vehicle you just passed may seem
to
be farther away from you than it really is.)
- Try not to pass more than one vehicle at a time on
two-lane roads. Reconsider before passing the
next vehicle.
Don’t overtake a slowly moving vehicle too rapidly.
Even though the brake lamps are not flashing,
it
may be slowing down or starting to turn.
If you’re being passed, make it easy for the
following driver
to get ahead of you. Perhaps you
can ease a little to the right.

Traveling to Remote Areas
It makes sense to plan your trip, especially when going
to a remote area. Know the terrain and plan your
route. You are much less likely to get bad surprises.
Get accurate maps of trails and terrain. Try
to learn of
any blocked or closed roads.
It’s also a good idea to travel with at least one other
vehicle.
If something happens to one of them, the other
can help quickly.
Does your vehicle have a winch? If
so, be sure to read
the winch instructions. In a remote area, a winch
can be handy
if you get stuck. But you’ll want to know
how
to use it properly.
Getting Familiar with Off-Road Driving
It’s a good idea to practice in an area that’s safe and
close
to home before you go into the wilderness.
Off-road driving does require some new and different
driving skills. Here’s what we mean.
Tune your senses
to different kinds of signals. Your
eyes, for example, need
to constantly sweep the terrain
for unexpected obstacles. Your ears need to listen
for unusual tire or engine sounds. With your arms,
hands, feet and body, you’ll need to respond
to
vibrations and vehicle bounce. Controlling your vehicle is
the key
to successful off-road
driving. One of the best ways
to control your vehicle
is
to control your speed. Here are some things to keep
in mind.
At higher speeds:
you approach things faster and you have less time
to scan the terrain for obstacles.
you have less time to react.
you have more vehicle bounce when you drive over
obstacles.
you’ll need more distance for braking, especially
since u’re on an [-.7aved surface.
When ; u’re driving R-road, bouncing and
quick changes in direction can easily throw
you out
of position. This could cause you to
lose control and crash.
So, whether you’re
driving on or
off the road, you and your
passengers should wear safety belts.

Scanning the Terrain
Off-road driving can take you over many different kinds of
terrain. You need
to be familiar with the terrain and its
many different features. Here are
some things to
consider.
Surface Conditions: Off-roading can take you over
hard-packed dirt, gravel, rocks, grass, sand, mud, snow
or ice. Each of these surfaces affects the steering,
acceleration and braking of your vehicle in different
ways. Depending upon the kind of surface you are on,
you may experience slipping, sliding, wheel spinning,
delayed acceleration, poor traction and longer braking
distances.
Surface Obstacles: Unseen or hidden obstacles can
be hazardous. A rock, log, hole, rut or bump can startle
you
if you’re not prepared for them. Often these
obstacles are hidden by grass, bushes, snow or even
the rise and fall of the terrain itself. Here are some
things to consider:
0 Is the path ahead clear?
Will the surface texture change abruptly up ahead?
Does the travel take you uphill or downhill?
(There’s more discussion of these subjects later.)
Will you have to stop suddenly or change direction
quickly? When you drive
over obstacles or rough terrain, keep a
firm grip on the steering wheel. Ruts, troughs or
other surface features can jerk the wheel out of your
hands
if you’re not prepared.
When you drive over bumps, rocks, or other obstacles,
your wheels can leave the ground. If this happens,
even with one or two wheels, you can’t control
the vehicle as well or at all.
Because you will be on an unpaved surface, it’s
especially important to avoid sudden acceleration,
sudden turns or sudden braking.
In a way, off-road driving requires a different kind of
alertness from driving on paved roads and highways.
There are no road signs, posted speed limits or
signal lights. You have to use your own good judgment
about what is safe and what isn’t.
Drinking and driving can be very dangerous on any
road. And this is certainly true for off-road driving. At the
very time you need special alertness and driving
skills, your reflexes, perceptions and judgment can be
affected by even a small amount of alcohol. You
could have a serious
- or even fatal - accident if you
drink and drive or ride with a driver who has been
drinking. See Drunken Driving
on page 4-2.

To identify the trailering capacity for your vehicle, you
should read the information in “Weight of the Trailer” that
appears later in this section.
If yours was built with trailering options, as many are,
it’s ready for heavier trailers. But trailering is different
than just driving your vehicle by itself. Trailering means
changes in handling, durability and fuel economy.
Successful, safe trailering takes correct equipment, and
it has
to be used properly.
That’s the reason for this part. In it are many time-tested,
important trailering tips and safety rules. Many of
these are important for your safety and that of your
passengers.
So please read this section carefully before
you pull a trailer.

If You Do Decide To Pull A Trailer
If you do, here are some important points:
There are many different laws, including speed limit
restrictions, having
to do with trailering. Make sure
your rig will be legal, not only where you live
but also where you’ll be driving.
A good source for
this information can be state or provincial police. Consider using a
sway control
if your trailer will
weigh
5,000 Ibs. (2 270 kg) or less. You should
always use a sway control
if your trailer will weigh
more than
5,000 Ibs. (2 270 kg). You can ask a
hitch dealer about sway controls.
Don’t tow a trailer at all during the first
500 miles
(800 km) your new vehicle is driven. Your engine,
axle or other parts could be damaged.
Then, during the first
500 miles (800 km) that you
tow a trailer, don’t drive over
50 mph (80 km/h)
and don’t make starts at full throttle. This helps your
engine and other parts of your vehicle wear in at
the heavier loads.
You can tow in
DRIVE (D). You may want to shift
the transmission
to THIRD (3) or, if necessary, a
lower gear selection
if the transmission shifts
too often (e.g., under heavy loads and/or hilly
conditions). See “Tow/Haul Mode” under Towing
a
Trailer on page 4-47.
Three important considerations have to do with weight:
0 the weight of the trailer,
the weight of the trailer tongue
0 and the weight on your vehicle’s tires.

As in the chart shown previously, SAE 5W-30 is the
only viscosity grade recommended for your vehicle. You
should look for and use only oils which have the API
Starburst symbol and which are also identified as
SAE 5W-30. If you cannot find such SAE 5W-30 oils,
you can use an SAE 1OW-30 oil which has the API
Starburst symbol,
if it's going to be 0°F (-18°C)
or above.
Do not use other viscosity grade oils, such as
SAE 1OW-40 or SAE 20W-50 under any conditions.
Notice: Use only engine oil with the American
Petroleum Institute Certified For Gasoline Engines
starburst symbol. Failure to use the recommended
oil can result in engine damage not covered by
your warranty.
GM Goodwrench@ oil meets all the requirements for
your vehicle.
If you are in an area of extreme cold, where the
temperature falls below
-20°F (-29"C), it is
recommended that you use either an SAE 5W-30
synthetic oil or an SAE OW-30 oil. Both will provide
easier cold starting and better protection for your engine
at extremely low temperatures.
Engine Oil Additives
Don't add anything to your oil. The recommended oils
with the starburst symbol are all you will need for
good performance and engine protection.
When to Change Engine Oil (GM Oil
Life System)
Your vehicle has a computer system that lets you know
when to change the engine oil and filter. This is
based on engine revolutions and engine temperature,
and not on mileage. Based on driving conditions,
the mileage at which an oil change will be indicated can
vary considerably. For the oil life system
to work
properly, you must reset the system every time the oil is
changed.
When the system has calculated that oil life has been
diminished, it will indicate that an oil change is
necessary.
A CHANGE ENGINE OIL message will
come on. Change your oil as soon as possible within
the next two times you stop for fuel. It is possible that,
if
you are driving under the best conditions, the oil life
system may not indicate that an oil change is necessarv
for over a year. However, your engine oil and filter
must be changed at least once a year and at this time
the system must be reset. It is also important
to
check your oil regularly and keep it at the proper level.
If the system is ever reset accidentally, you must
change your oil at
3,000 miles (5 000 km) since your
last oil change. Remember to reset the oil life system
whenever the oil is changed.
