1997 GMC SIERRA wiper blades

Windshield Wipers
You control the windshield
wipers by turning the knob
with the wiper symbol on it.
For a single wiping cycle, turn the knob to MIST. Hold
it there until the wipers start, then let
go. The wipers will
stop after one cycle. If you want more cycles, hold the
knob
on MIST longer.
You can set the wiper eea ror
a long or short delay
between wipes. This can be very useful in light rain or
snow. Turn the knob to choose the delay time. The
closer to
LOW, the shorter the delay. For
steady wiping at low speed,
turn the knob to the
LOW position. For high-speed wiping, turn the knob
further, to
HIGH. To stop the wipers, move the knob
to OFF.
Damaged wiper blades may prevent you from seeing
well enough to drive safely,
To avoid damage, be sure to
clear ice and snow from the wiper blades before using
them. If they are frozen to the windshield, carefully
loosen or thaw them.
If your blades do become
damaged, get new blades
or blade inserts.
Heavy ice or snow can overload your wipers. The
windshield wiper motor
is protected from overload by a
circuit breaker and a fuse. If the motor overheats due to
heavy
snow, etc., the wiper will stop until the motor
cools. Although protected from electrical overload,
overload due to heavy snow, etc. may cause wiper
linkage damage. Always clear ice and heavy snow from
the windshield before using your windshield wipers.

Driving in Rain and on Wet Roads
4
4 I- -
your tire-to-road traction isn’t as good as on dry roads.
And,
if your tires don’t have much tread left, you’ll get
even less traction. It’s always wise to go slower and be
cautious
if rain starts to fall while you are driving. The
surface may get wet suddenly when your reflexes
are
tuned for driving on dry pavement.
The heavier the rain, the harder
it is to see. Even if your
windshield wiper blades are in good shape, a heavy rain
can make it harder to see road signs and traffic signals,
pavement markings, the edge of the road and even
people walking.
It’s wise to keep your wiping equipment in good shape
and keep your windshield washer tank filled with
washer fluid. Replace your windshield wiper inserts
when they show signs of streaking or missing areas on
the windshield,
or when strips of rubber start to separate
from the inserts.
Rain and wet roads can mean driving trouble. On a wet
road, you can’t stop, accelerate or turn as well because

When you want to leave the freeway, move to the proper
lane well in advance. If you miss your exit, do not,
under any circumstances,
stop and back up. Drive on
to the next exit.
The exit ramp can be curved, sometimes quite sharply.
The exit speed is usually posted.
Reduce your speed according to your speedometer, not
to your sense of motion. After driving for any distance
at higher speeds,
you may tend to think you are going
slower than you actually are.
Before Leaving on a Long Trip
Make sure you’re ready. Try to be well rested. If you
must
start when you’re not fresh -- such as after a day’s
work
-- don’t plan to make too many miles that first part
of the journey. Wear comfortable clothing and shoes you
can easily drive in.
Is your vehicle ready for a long trip?
If you keep it
serviced and maintained, it’s ready to go. If it needs
service, have
it done before starting out. Of course,
you’ll find experienced and able service experts in
GM
dealerships all across North America. They’ll be ready
and willing to help
if you need it.
Here are some things you can check before a trip:

a
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?

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.
Care of Safety Belts
Keep belts clean and dry.
A CAUTION:
Do not bleach or dye safety belts. If you do, it
may severely weaken them. In a crash, they
might not be able to provide adequate protection. Clean safety belts only with mild soap and
lukewarm water.
Glass
Glass should be cleaned often. GM Glass Cleaner (GM
Part No. 1050427) or a liquid household glass cleaner
will remove normal tobacco smoke and dust films on
interior glass.
I
Don’t use abrasive cleaners on glass, because they may
cause scratches. Avoid placing decals on the inside rear
window, since they may have to be scraped
off later.
If abrasive cleaners are used on the inside
of the rear
window, an electric defogger element may be damaged.
Any temporary license should not be attached across the
defogger grid.
Cleaning the Outside of the
Windshield and Wiper Blades
If the windshield is not clear after using the windshield
washer, or if the wiper blade chatters when running,
wax, sap or other material may be on the blade
or windshield.
Clean the outside of the windshield with
GM Windshield
Cleaner, Bon
Ami@ (non-scratching glass cleaning
powder),
GM Part No. 1050011 or equivalent. The
windshield
is clean if beads do not form when you rinse
it with water.
Grime from the windshield will stick to
the wiper blades
and affect their performance. Clean the blade by wiping
vigorously with a cloth soaked in full-strength windshield
washer solvent. Then rinse the blade with water.
Check the wiper blades and clean them as necessary;
replace blades that look worn.

At Least Twice a Year
Restraint System Check
Make sure the safety belt reminder light and all your
belts, buckles,
latch plates, retractors and anchorages are
working properly. Look for any other loose or damaged
safety belt system
parts. If you see anything that might
keep a safety belt system from doing its job, have it
repaired. Have any torn or frayed safety belts replaced.
Also look for any opened or broken air bag coverings,
and have them repaired or replaced. (The air bag system
does
not need regular maintenance.)
Wiper Blade Check
Inspect wiper blades for wear or cracking. Replace blade
inserts that appear worn or damaged or that streak or
miss areas of the windshield. Also see “Wiper Blades,
Cleaning” in the Index.
Air Cleaner Filter Restriction Indicator Check
Your vehicle has an indicator on the engine that lets you
know when the air cleaner filter is dirty and needs
to be
changed. Check indicator at least twice a year or when
your oil is changed. See “Air Cleaner” in
the Index for
more information. Inspect your air cleaner filter restriction indicator more often
if the vehicle is used in
dusty areas or under off road conditions.
Manual Transmission Check
Check the transmission fluid level; add if needed. See
“Manual Transmission” in
the Index. Check the system for
leaks. A fluid loss may indicate a problem. Have the
system inspected and repaired if needed.
Automatic Transmission Check
Check the transmission fluid level; add if needed. See
“Automatic Transmission” in the Index.
A fluid loss
may indicate a problem. Check the system and repair
if needed.
Hydraulic Clutch System Check
Check the fluid level in the clutch reservoir. See
“Hydraulic Clutch Fluid” in the Index. A fluid loss in
this system could indicate a problem. Have the system
inspected and repaired
at once.
At Least Once a Year
Key Lock Cylinders Service
Lubricate the key lock cylinders with the lubricant
specified
in Part D.
