The tape player should be cleaned regularly after
every 50 hours of use. The radio may display
CLEAN to indicate that the tape player has been
used for 50 hours without resetting the tape
clean timer. If this message appears on the
display, the cassette tape player needs to be
cleaned. It will still play tapes, but it should
be cleaned as soon as possible to prevent damage
to the tapes and player. If there is a reduction in
sound quality, try a known good cassette to
see if the tape or the tape player is at fault. If this
other cassette has no improvement in sound
quality, clean the tape player.
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.When cleaning the cassette tape player with the
recommended non-abrasive cleaning cassette, it is
possible that the cassette may eject, because
the cut tape detection feature on the radio
may recognize it as a broken tape, in error. To
prevent the cleaning cassette from being ejected,
use the following steps:
1. Turn the ignition on.
2. Turn the radio off.
3. Press and hold the TAPE DISC button for
ve seconds. READY will appear on the
display and the cassette symbol will ash for
ve seconds.
4. Insert the scrubbing action cleaning cassette.
5. Eject the cleaning cassette after the
manufacturer’s recommended cleaning time.
When the cleaning cassette has been
ejected, the cut tape detection feature
will be active again.
298

A non-scrubbing action, wet-type cleaner which
uses a cassette with a fabric belt to clean the tape
head can be used. 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 the player is cleaned, press and hold the
eject button for ve seconds to reset the CLEAN
indicator. The radio will display --- or CLEANED 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
the tape player is serviced.Care of Your CDs and DVDs
Handle CDs and DVDs carefully. Store them in
their original cases or other protective cases and
away from direct sunlight and dust. The CD
and DVD player scans the bottom surface of the
disc. If the surface of a CD or DVD is damaged,
such as cracked, broken, or scratched, the CD or
DVD will not play properly or not at all. If the
surface of a CD or DVD is soiled, take a soft, lint
free cloth or dampen a clean, soft cloth in a
mild, neutral detergent solution mixed with water,
and clean it. Make sure the wiping process
starts from the center to the edge. If a dampened
cloth was used to clean the disc, dry it with a
dry cotton cloth.
Do not touch the bottom side of a CD or DVD
while handling it; this could damage the surface.
Pick up CDs or DVDs by grasping the outer edges
or the edge of the hole and the outer edge.

First Aid Kit and Tool Kit
The rst aid and tool kit is located in the storage bin
on top of the spare tire on SUV models. It is held in
place with a hook and loop fastener strap.
On SUT models, the kit is in the rear cargo
compartment on the passenger side of the vehicle.
The kit includes a rst aid kit (A), a ashlight (C),
a tire pressure gage (B), and a multi-purpose
tool set (D).
The tire pressure gage has a reset button in the
gage stem. After taking a pressure reading,
press the button to reset the gage to zero.
Front Mounted Receiver
Your vehicle is equipped with a front mounted
receiver.
You can use the receiver with a power winch
platform (described later in this section) or with
other accessories.

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 0W-30 oil. Both will
provide easier cold starting and better protection
for the engine at extremely low temperatures.
Engine Oil Additives
Do not add anything to the oil. The recommended
oils with the starburst symbol that meet GM
Standard GM6094M are all you will need for good
performance and engine protection.
Engine Oil Life System
When to Change Engine Oil
Your vehicle has a computer system that lets you
know when to change the engine oil and lter.
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 600 miles
(1 000 km). It is possible that, if you are driving
under the best conditions, the oil life system may
not indicate that an oil change is necessary for
over a year. However, your engine oil and
lter must be changed at least once a year and at
this time the system must be reset. Your dealer
has GM-trained service people who will perform
this work using genuine GM parts and reset
the system. 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.
