Press and hold the TAPE AUX button for five
seconds. The tape symbol
on the display will flash
for two seconds.
Insert the scrubbing action cleaning cassette while
the tape symbol is flashing.
Eject
the cleaning cassette after the manufacturer’s
recommended cleaning time.
When the cleaning cassette has been ejected, the cut tape
detection feature is 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 EJECT 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 Compact Discs
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 signal surface when handling
discs. Pick up discs by grasping the outer edges or the
edge
of the hole and the outer edge.
Care of Your Compact Disc Player
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.
Fixed Mast Antenna
The fixed mast antenna can withstand most car washes
without being damaged.
If the mast should ever become
slightly bent,
you can straighten it out by hand. If the
mast is badly bent, as
it might be by vandals, you should
replace
it.
Check every once in a while to be sure the mast is still
tightened to the fender.

Windshield Washer Fluid: Is the reservoir full? Are
all windows clean inside and outside?
Wiper Blades: Are they in good shape?
Fuel, Engine Oil, Other Fluids: Have you checked
all levels?
Lamps: Are they all working? Are the lenses clean?
Tires: They are vitally important to a safe,
trouble-free trip.
Is the tread good enough for
long-distance driving? Are the tires
all inflated to the
recommended pressure?
Weather Forecasts: What’s the weather outlook
along your route? Should you delay your trip a short
time
to avoid a major storm system?
Maps: Do you have up-to-date maps?
Highway Hypnosis
Is there actually such a condition as “highway
hypnosis”? Or is
it just plain falling asleep at the wheel?
Call
it highway hypnosis, lack of awareness,
or whatever.
There
is something about an easy stretch of road with
the same scenery, along with the hum
of the tires on the
road, the drone of the engine, and the rush of the wind
against the vehicle that can make
you sleepy. Don’t let it
happen to you!
If it does, your vehicle can leave the
road
in less than a second, and you could crash and
be injured.
What can
you do about highway hypnosis? First, be
aware that it can happen.
Then here are some tips:
0 Make sure your vehicle is well ventilated, with a
comfortably cool interior.
0 Keep your eyes moving. Scan the road ahead and
to the sides. Check your mirrors and your
instruments frequently.
If you get sleepy, pull off the road into a rest, service
or parking area and take
a nap, get some exercise, or
both. For safety, treat drowsiness on
the highway as
an emergency.

If you plan on driving in another country outside the
United States or Canada, the proper fuel may be hard to
find. Never use leaded gasoline or any other fuel not
recommended in the previous text on fuel. Costly repairs
caused by
use of improper fuel wouldn’t be covered by
your warranty.
To check on fuel availability, ask an auto club, or
contact
a major oil company that does business in the
country where you’ll be driving.
You can also write
us at the following address for
advice. Just tell us where you’re going and give your
Vehicle Identification Number (VIN).

Filling Your Tank
A CAUTION:
--
Gasoline vapor is highly flaml,,~ble. It burns
violently, and that can cause very bad injuries.
Don’t smoke if you’re near gasoline or refueling
your vehicle. Keep sparks, flames and smoking
materials away from gasoline.

Downloaded from www.Manualslib.com manuals search engine When to Add Engine Oil
If the oil is at or below the ADD line, then you’ll need
to add at least one quart of oil. But you must use the
right kind. This part explains what kind
of oil to use. For
crankcase capacity, see “Capacities and Specifications’’
in the Index.
I NOTICE:
Don’t add too much oil. If your engine has so
much oil that the oil level gets above the
cross-hatched area that
shows the proper
operating range, your engine could be damaged.
Be sure to fill it enough to put the level somewhere in
the proper operating range. Push the dipstick all the way
back in when you’re through.
What Kind of Engine Oil to Use
Oils recommended for your vehicle can be identified by
looking for the “Starburst” symbol. This symbol
indicates that the oil has been certified by the American
Petroleum Institute (API).
Do not use any oil which
does
not carry this Starburst symbol.
If you change your own oil,
be sure you use oil that has
the Starburst symbol
on the
front
of the oil container. If
you have your oil changed
for you, be sure the oil put
into your engine is
American Petroleum
Institute certified for
gasoline engines.
You should also use the proper viscosity oil for your
vehicle, as shown
in the following chart:

DO
NOT USE SAE 2OW-50 OR AMY OTHER
GRADE OIL NOT RECOMMENDED
As shown in the chart, SAE 5W-30 is best for your
vehicle. However,
you can use SAE low-30 if it's going
to be
0°F (- 18 "C) or above. These numbers on an oil
container show its viscosity, or thickness.
Do not use
other viscosity oils, such as
SAE 20W-50.
I 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 where the temperature falls below
-20°F (-29"C), consider using 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.

When to Check and Change Lubricant
Refer to the Maintenance Schedule to determine how
often
to check the lubricant and when to change it. See
“Scheduled Maintenance Services” in the Index.
How to Check Lubricant
If the level is below the bottom of the filler plug hole,
you’ll need to add some lubricant. Add enough lubricant
to raise the level to the bottom
of the filler plug hole.
What to Use
Refer to the Maintenance Schedule to determine what
kind of lubricant
to use. See “Recommended Fluids and
Lubricants” in the Index.
Engine Coolant
The cooling s stem in your vehicle is filled with
DEX-COOL engine coolant. This coolant
is designed
to remain in your vehicle for
5 years or 150,000 miles
(240
000 km) whichever occurs first, if you add only
DEX-COOL’ extended life coolant.
The following explains your cooling system and how to
add coolant when it is low. If you have a problem with
engine overheating,
see “Engine Overheating” in
the Index.
A 50/50 mixture of water and DEX-COOL@
coolant will:
Give freezing protection down to -34°F (-37°C).
0 Give boiling protection up to 265 “F ( 129°C).
0 Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as

Your Vehicle and the Environment
Proper vehicle maintenance not only helps to keep your
vehicle in good working condition, but also helps the
environment. All recommended maintenance procedures
are important. Improper vehicle maintenance can even
affect the quality
of the air we breathe. Improper fluid
levels
or the wrong tire inflation can increase the level
of emissions from your vehicle. To help protect our
environment, and to keep your vehicle in good
condition, please maintain your vehicle properly.
