Downloaded from www.Manualslib.com manuals search engine 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
possible.
The air conditioning will not work when the temperature is below
40°F
(4 O C).
Lubrication
Accelerator Control System
Refer to the Maintenance Schedule to determine how often the accelerator
linkage pivot points must be lubricated and what type of lubricant
to use.
Accelerator cables and cruise control cables should not be lubricated. Any
cables that are worn or are hard to pull should be replaced.
When cleaning the engine compartment with water or steam, avoid directing
the flow onto the throttle linkage in a manner that would cau\
se moisture
to
enter the cables.
Hood Latches and Hood Hinge
Refer to the Maintenance Schedule to determine how to lubricate the hood
latch and hood hinge assembly.
Sliding Door Tracks
Your vehicle’s sliding door has three tracks which need lubrication.
For the upper and lower tracks, open the door, wipe the track\
clean and then lubricate with Lubriplate
TM 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
Lubriplate
TM 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.
For exposed surfaces, such as door checks, door lock bolts, lock striker
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.

Downloaded from www.Manualslib.com manuals search engine Door weatherstrips and rubber hood bumpers should be wiped clean with a
wet cloth and 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.
Some parts
that need lubricating are hard to get at. Window regulators and
controls are inside the doors. You can get to these by removing
the trim
panels.
Refer to the Maintenance Schedule to determine how often to lubricate
these items and what type
of lubricant to use.
Lock Cylinders
To be sure your locks operate properly, they must be lubricated.
Refer to the Maintenance Schedule to determine how often to lubricate them
and what type of 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.
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 engine components.
Engine Control Module System
This system has an oxygen (02) sensor that helps keep your engine’s
air-fuel mixture at a proper level. Use only unleaded fuel in your vehicle.
If
you use leaded fuel, you could damage your oxygen (02) sensor and affect
your vehicle’s emissions.

Downloaded from www.Manualslib.com manuals search engine Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from short circuits by a
combination of fuses, circuit breakers, and fusible thermal
links in the
wiring itself. This greatly reduces the chance of fires caused by electrical
problems. See “Fuses and Circuit Breakers”
in the Index for more
information.
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 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 block. See
“Trailer Wiring Harness”
in the Index.

Downloaded from www.Manualslib.com manuals search engine ruse Block
The fuse block is
under the instrument
panel
on the driver’s
side. Remove the
cover with
a
screwdriver.
To remove fuses if you don’t have a fuse extractor, hold the end of the fuse
between your thumb and index finger and pull straight out.
Be sure to use the correct fuse.
If you ever have a problem on the road and
don’t have a spare fuse, you can “borrow” one
of the correct value. Just pick
some feature of your vehicle that you can get along without-like the radio
or cigarette lighter-and use its fuse, if it is of the value you need. Replace
it as
soon as you can. See “Fuses and Circuit Breakers” in this section.

Downloaded from www.Manualslib.com manuals search engine 13. TIRE AND WHEEL ROTATION AND INSPECTION - For
proper wear and maximum tire life, rotate tires at the first
6,000 miles
(10
000 kilometers) for Schedule I or 7,500 miles (12 500 kilometers)
for Schedule I1 and
then every 15,000 miles (25 000 kilometers)
thereafter. Follow the instructions and patterns shown in Sectio\
n
6.
Check tires for uneven wear or damage. If irregular or premature wear
is apparent, check wheel alignment. Also, check for damaged wheels.
See “Tires” in the Index for more information.
14.
DRIVE AXLE SERVICE - Check readfront axle fluid level and add
as needed. Check constant velocity joints and axle seals for leaking.
Locking Differential - Drain fluid at first oil change and refill.
Check fluid level and add as needed at subsequent oil changes. In
dusty areas or trailer towing applications, drain fluid at every
15,000 miles (24 135 kilometers) and refill.?
Standard Differential - Check fluid level and add as needed at
every oil change. In dusty areas or trailer towing applications\
,
drain fluid every
15,000 miles (24 135 kilometers) and refill.?
15. BRAKE SYSTEM INSPECTION - When the engine oil is changed,
inspect the lines and hoses for proper hookup, binding, leaks, cracks,
chafing, etc. Check the parking brake adjustment, and the fluid\
level in the master cylinder. A low fluid level can indicate
worn disc brake pads
which may need to be serviced.?
When the wheels are removed for rotation, inspect disc brake pads for
wear and rotors for surface condition. Also inspect drum brake linings
for wear and cracks. Inspect other brake parts, including drums, wh\
eel
cylinders, parking brake, etc. at the same time.
Inspect brakes more often if driving habits or conditions resul\
t in
frequent braking.
-f A fluid loss in these systems may indicate a problem. Have them inspected a\
nd
repaired at once.
