1995 GMC SIERRA oil type

display an error and eject the cartridge. This is normal and is the result of an
added feature
in the tape player that detects broken tapes. If an e.rror occurs,
you
will need to insert the cleaning cassette at least 3 times to thoroughly
clean the tape player.
You may prefer to use
a non-scrubbing action, wet-type cleaner. This type
of cleaner uses
a fabric belt to clean the tape head. This type of cleaner
cassette will
not cause an error, but it may not clean the tape player as
thoroughly as the scrubbing type cleaner.
A scrubbing action cleaner cassette is available through your retailer (SPO
# 12344600).
Cassettes are subject to wear and the sound quality may degrade over time.
Always verify that the cassette tape is
in good condition and the tape player
is clean before obtaining service on your tape player.
NOTICE:
Cassette tape adapter kits for portable CD players will not work
in your cassette player. These adapters
will cause the radio to
display an error and the adapter cassette
will be ejected.
Care of 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.
Fixed Mast Antenna
The fixed mast antenna can withstand most car washes without be.ing
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
rep1 ace it.
Check every once
in a while to be sure the mast is still tightened to the
fender.

Windshield Wiper Blade Inserts
To replace the
windshield wiper
blade insert, lift
the
wiper arm and rotate
the blade until
it is
facing away from the
windshield.
Unlatch the end
of the insert from the holding clips. Remove the insert and
slide
a new one in place. Make sure the blade is secured in the clips.
Air Conditioning
Every now and then have your dealership check your air conditioning
system to be sure it
has not lost any cooling ability. If you think the system
is not working properly, have your dealership check it out as soon as
possi bleb
The air conditioning will
not work when the temperature is below 40°F
(4°C).
Fluid Leak Check
After the vehicle has been parked for a while, inspect the surface under the
vehicle for water, oil, fuel
or other fluids. Water dripping from the air
conditioning system after it has been used is normal.
If you notice fuel leaks
or fumes, the causes should be found and corrected at once.
Lock Cylinders
To be sure your locks operate properly, they must be lubricated. Your
vehicle’s maintenance schedule will tell you how often to lubricate them.
See “Recommended Fluids and Lubricants” in the Index for
the proper
lubricant to use.
You should
not use penetrating oils because they could wash out the factory
installed lubricant and cause
the lock to bind. De-icers which contain
alcohol could also
wash away the lubricant, so be sure to lubricate the lock
after using
a de-icer of this type.

Using Solvent-Type Cleaner on Fabric
First, see if you have to use solvent-type cleaner at all. Some spots and
stains will clean
off better with just water and mild soap.
If you need to use a solvent:
Gently scrape excess soil from the trim material with a clean, dull knife
or scraper. Use very little cleaner, light pressure and clean cloths
(preferably cheesecloth). Cleaning should start at the outside of the
stain, “feathering” toward the center. Keep changing to
a clean section
of the cloth.
When you clean a stain from fabric, immediately dry the area with a
blow dryer to help prevent a cleaning ring. (See the previous NOTICE.)
Fabric Protection
Your vehicle has upholstery and carpet that has been treated with
Scotchgard TM Fabric Protector, a 3M product. Scotchgard TN protects fabrics
by repelling oil and water, which are the carriers of most stains. Even with
this protection, you still need to clean your upholstery and carpet often to
keep
it looking new.
Further information
on cleaning is available by calling 1-800-433-3296 (in
Minnesota, 1-800-642-6 167).
Special Cleaning Problems
Greasy or Oily Stains
Stains caused by grease, oil, butter, margarine, shoe polish, coffee with
cream, chewing gum, cosmetic creams, vegetable oils, wax crayon, tar and
asphalt can be removed as follows:
Carefully scrape off excess stain.
Follow the solvent-type instructions described earlier.
Shoe polish, wax crayon, tar and asphalt will stain if left on a vehicle
seat fabric. They should be removed as soon
as possible. Be careful,
because the cleaner will dissolve them and may cause them to spread.
Non-Greasy Stains
Stains caused by catsup, coffee (black), egg, fruit, fruit juice, milk, soft
drinks, wine, vomit, urine and blood can be removed as follows:
Carefully scrape off excess stain, then sponge the soiled area with cool
water.

If an odor lingers after cleaning vomit or urine, treat the area with a
waterhaking soda solution:
I teaspoon (5 ml> of baking soda to 1 cup
(250 ml) of lukewarm water.
If needed, clean lightly with solvent-type cleaner.
Combination Stains
Stains caused by candy, ice cream, mayonnaise, chili sauce and unknown
stains can be removed as follows:
0 Carefully scrape off excess stain, then clean with cool water and allow
to dry.
0 If a stain remains, clean it with solvent-type cleaner.
Cleaning Vinyl
Use warm water and a clean cloth.
0 Rub with a clean, damp cloth to remove dirt. You may have to do it
more than once.
0 Things like tar, asphalt and shoe polish will stain if you don’t get them
off quickly. Use
a clean cloth and GM vinyMeather cleaner.
Cleaning Leather
Use a soft cloth with lukewarm water and a mild soap or saddle soap.
For stubborn stains, use GM vinylheather cleaner.
Never use oils, varnishes, solvent-based or abrasive cleaners, furniture
polish or shoe polish on leather.
0 Soiled leather should be cleaned immediately. If dirt is allowed to work
into finish,
it can harm the leather.
Cleaning the Top of the Instrument Panel
Use only mild soap and water to clean the top surfaces of the instrument
panel. Sprays containing silicones
or waxes may cause annoying reflections
in the windshield and even make it difficult to see through the windshield
under certain conditions.

Air Conditioning Refrigerants
Not all air conditioning refrigerants are the same. If the air conditioning
system
in your vehicle needs refrigerant, be sure the proper refrigerant is
used.
If you’re not sure, ask your GM dealer. For additional information, see
your “Warranty and Owner Assistance Information” booklet,
NOTICE:
R-134A refrigerant is not compatible with R-12 refrigerant in
an air conditioning system.
R-12 in an R-134A system will cause
compressor failure, refrigerant oil sludge,
or poor air
conditioning system performance.

If your engine has more than one emissions classification, the classification
is determined by the Gross Vehicle Weight Rating (GVWR) of your vehicle
as shown on the Certification Label. See “Loading Your Vehicle”
in the
Index.
Once you’ve determined your engine type and,
if necessary, emissions
classification, you’ll need to decide which of the two schedules is right for
your vehicle. See Definitions for Maintenance Schedule
I and Maintenance
Schedule

Schedule I Definition - Gasoline Engines With Light Duty
Emissions
Follow Maintenance Schedule I if any one of these is true for your vehicle:
iII Most trips are less than 5 to 10 miles (8 to 16 km). This is particularly
important when outside temperatures are below freezing.
0 Most trips include extensive idling (such as frequent driving in
stop-and-go traffic).
You operate your vehicle in dusty areas or off-road frequently.
0 You frequently tow a trailer.
Schedule
I should also be followed if the vehicle is used for delivery
service, police, taxi, or other commercial application.
