1994 CHEVROLET S10 check engine

Downloaded from www.Manualslib.com manuals search engine When to Check
Check your ..’ :s once a month or more. Also, check the tire pressure of the
spare tire.
How to Check
Use a good quality pocket-type gage to check tire pressure. Si\
mply looking at the tires will
not tell you the pressure, especially if you have radial tires
- which may look properly inflated even if they’re underinflated.
If your tires have valve caps, be sure to put them back on. The\
y help prevent
leaks by keeping out
dirt and moisture.
Special Tire Inflation
If you have 31xlOSOR15LT/C tires on your vehicle, and:
- You’ll be driving for very long at speeds of 66 mph (105 km/h) to
75 mph (120 km/h) where legal, inflate tires to 10 psi (70 Wa) more
than the recornended cold inflation pressures.
- You’ll be driving for very long at speeds of 76 mph (120 km/h) to
85 mph (1 35 km/h) where legal, cold inflation pressures should be
increased by
10 psi (70 Wa) and you must also reduce axle load
capacity by
10%. Do not drive over 85 mph (135 km/h) even when
it’s legal.
Inflation pressures should never exceed 10 psi (70 Pa) above the
inflation specified for
the maximum load of the tire.

Downloaded from www.Manualslib.com manuals search engine When lt’s Time for New Tires
a
One way to tell when
it’s time for new tires
is to check the
treadwear indicators,
which will appear
when your tires have
only
2/32 inch (1.6
mm) or less of tread
remaining.
You need a new tire if
You can see the indicators at three or more places around the tire.
You can see cord or fabric showing through the tire’s rubber.
0 The tread or sidewall is cracked, cut or snagged deep enough to show
cord or fabric.
0 The tire has a bump, bulge or split.
The tire has a puncture, cut, or other damage that can’t be re\
paired well
because of the
size or location of the damage.
Buying New Tires
To find out what kmd and size of tires you need, look at the
Certificatioflire label.
The tires installed on your vehicle when it was new had a Tire Performance
Criteria Specification (PC Spec) number on each tire’s sidewall. When you
get new tires, get ones with that same TPC Spec number. That way, your
vehicle will continue to have tires that
are designed to give proper
endurance, handling, speed rating, traction, ride and other thin\
gs during
normal service on your vehicle.
If your tires have an all-season tread
design, the TPC number will be followed by a
“MS” (for mud and snow).
If you ever replace your tires with those not having a
TPC Spec number,
make sure they are the same size, load range, speed rating and construction
type (bias, bias-belted or radial) as your original tires.

Downloaded from www.Manualslib.com manuals search engine 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.
von’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.
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 or other material may b\
e on the
blade or windshield.
Clean the outside
of the windshield with GM Windshield Cleaner, Bon-Ami
Powder@ (GM Part
No. 1050011). The windshield is clean if beads do not
form when you rinse it with water.
Clean the blade by wiping vigorously with a cloth soaked in full strength
windshield washer solvent. Then rinse the blade with water.
Wiper blades should be checked on a regular basis and replaced\
when worn.
Cleaning the Outside of Your Vehicle
The paint finish on your vehicle provides beauty, depth of color, gloss
retention and durability.
Washing Your Vehicle
The best way to preserve your vehicle’s finish is to keep it clean by washing
it often with lukewarm or cold water.
Don’t wash your vehicle
in the direct rays of the sun. Don’t use strong soaps
or chemical detergents. Use liquid hand, dish or car washing (\
mild
detergent) soaps. Don’t use cleaning agents that contain aci\
d or abrasives.
All cleaning agents should be flushed promptly and not allowed \
to dry on
the surface, or they could stain. Dry the finish with a soft,\
clean chamois or
a
100% cotton towel to avoid surface scratches and water spotting.
High pressure vehicle washes may cause water to enter your vehicle.

Downloaded from www.Manualslib.com manuals search engine Headlights
The headlight wiring is protected by a circuit breaker in the light switch. An
electrical overload will cause the lights to go on and off, or in some cases to
remain
off. If this happens, have your headlight wiring checked right away.
Windshield Wipers
The windshield wiper motor is protected by a circuit breaker and a fuse. If
the motor overheats due to heavy snow, etc., the wiper will stop until .the
motor cools. If the overload is caused by some electrical problem and not
snow, etc., be sure to get it fixed.
Power Windows and Other Power Options
Circuit breakers in the fuse panel protect the power windows and other
power accessories. When the current load is too heavy, the circuit breaker
opens and closes, protecting the circuit until the problem is fixed.
Trailer Wiring Harness
The optional seven-wire trailer wiring harness is protected by an in-line
fuse in the battery feed wire. This fuse
is near the junction block. See
“Trailer Wiring Harness”
in the Features & Controls section.
