Single Belt Accessory Drive
Your new vehicle uses a serpentine belt that is lighter, more durable and fuel
efficient than systems with several belts.
The belt runs over
or around the pulleys on the engine. A tensioner is used
to keep the belt tight at all times. The tensioner also makes replacing the
belt easier.

lubricate with Lubriplate@ White Grease.
For the outside middle track, close the door after you finish \
the upper and
lower tracks. Then, wipe the track clean and lubricate with Lu\
briplateB White
Grease.
Body
Normal use of your vehicle will cause metal-to-metal wear at some points \
on
the cab and body
if they are not lubricated.
tor exposed surfaces, such as door checks, door lock bolts, lock s\
triker
plates, dovetail bumper wedges, etc., a thin film
of engine oil should be
applied.
Where oil holes are provided in the body or cab, a dripless \
oil can be used.
The seat adjusters and seat track should be lubricated with chassis grease.
Door weatherstrips and rubber hood bumpers should be lightly coated with
a
rubber lubricant.
Never use
too much of any lubricant and be sure to wipe up any extra
lubricant when you are finished.

Lock Cylinders
To be sure your locks operate properly, they must be lubricated. \
The
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 th\
e 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.
Exhaust System
To help prevent damage to your exhaust system, do not continue to drive
your vehicle
if you notice:
Engine misfiring
Loss of performance
Other unusual operating conditions
Have your engine and exhaust system serviced regularly.
Three- Way Catalytic Converter
Your vehicle’s three-way catalytic converter is designed to reduce the
pollutants in your vehicle’s exhaust. Use only unleaded fuel in your vehicle.
If
you use leaded fuel, you could damage your three-way catalytic \
converter,
and other emission control components.
Malfunction Indicator Lamp (SERVICE ENGINE SOON light)
The Malfunction Indicator Lamp (SERVICE ENGINE SOONlight) on y\
our instrument panel lets you know when your emission system needs \
service.
The light will come on briefly when you start your engine to let you know
that the system is working.
If it does not come on when you start your
engine, or
if it comes on and stays on while you’re driving, your system \
may
need service. Your vehicle should still be driveable, but you should have your
system serviced right away.

suds.
Rinse the section with a clean, wet sponge.
Wipe off what’s left with a slightly damp paper towel or cloth.
Then dry it immediately with an air hose, a hair dryer or a heat lamp.

Wipe with a clean cloth.
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 it, then:
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 an air hose, hair dryer,
or heat lamp to help prevent a cleaning ring. (See
previous
NOTICE.)
Fabric Protection
Your vehicle has upholstery that has been treated with ScotchgardTM \
Fabric
Protector, a 3M product. ScotchgardTM protects fabrics by repell\
ing oil and
water, which are the carriers of most stains. Even with this protection, you
still need
to clean your upholstery often to keep it looking new.
Further information on cleaning is available by calling 1-800-43\
3-3296 (in
Minnesota, 1-800-642-61 67).
Special Cleaning Problems
Greasy or Oily Stains: Like grease, oil, butter, margarine, shoe polish, coffee
with cream, chewing gum, cosmetic creams, vegetable oils, wax crayon, tar
and asphalt.
Carefully scrape off excess stain.
Then follow the solvent-type instructions above.

Downloaded from www.Manualslib.com manuals search engine 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 bleed.
Non-Greasy Stains: Like catsup, coffee (black), egg, fruit, fruit juice, milk,
soft drinks, wine, vomit, urine and blood.
Carefully scrape off excess stain, then sponge the soiled area \
with cool
water.
If a stain remains, follow the foam-type instructions above.
If an odor lingers after cleaning vomit or urine, treat the area with a
watedbaking soda solution:
1 teaspoon (5 ml) of baking soda to 1 cup
(250 ml) of lukewarm water.
Finally, if needed, clean lightly with solvent-type cleaner.
Combination Stains: Like candy, ice cream, mayonnaise, chili sauce and
unknown stains.

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 s\
top until the
motor cools. If the overload is caused by some electrical prob\
lem 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 a\
nd other power
accessories. When the current load is too heavy, the circuit b\
reaker opens
and closes, protecting the circuit until the problem is fixed
or goes away.
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 bloc\
k. See “Trailer
Wiring Harness” in the Index.
Fuse Block
K3629
The fuse block is under the instrument panel on the driver’\
s side. You can
remove the cover with
a screwdriver and then remove fuses with a fuse
extractor. To remove fuses
if you don’t have one, hold the end of the fuse
between your thumb and index finger and pull straight out.
