HEADLIGHT WASHERS — IF EQUIPPED
The Headlight Washers are recessed into the top of
the fascia, centrally located below each headlight.
The windshield wiper/washer control lever operates
the headlight washers when the ignition switch is in the
ON position and the headlights are ON. The lever is
located on the left side of the steering column.
To use the headlight washers, push the washer knob,
located on the end of the multifunction lever, inward to
the second detent to activate the windshield washers
and release it. When this is done, the two stationary
washer nozzles at each headlight spray one timed
high-pressure spray of washer fluid onto each headlight
lens. In addition, the windshield washers will spray the
windshield and the windshield wipers will cycle.
NOTE:After turning the ignition switch and head-
lights ON, the headlight washers will operate on the
first spray of the windshield washer and then every
eleventh spray after that. REAR WINDOW FEATURES
REAR WINDOW WIPER/WASHER
The rear window wiper/washer control is located on
the right side of the steering column. (fig. 56)
Rotate the switch upward to the first detent
position for rear wiper operation.
Rotate the switch upward past the first detent
position to activate the rear washer. The washer
pump will continue to operate as long as the
switch is held. Upon release, the wiper will cycle three
times before returning to the set position. (fig. 57)
If the rear wiper is operating when the ignition is
turned to the LOCK position, the wiper will automati-
cally return to the “Park” position. When the vehicle is
restarted, the wiper will resume function at whichever
position the switch is set at.

You or others can be badly burned by hot
engine coolant (antifreeze) or steam
from your radiator. If you see or hear steam
coming from under the hood, do not open the
hood until the radiator has had time to cool.
Never try to open a cooling system pressure cap
when the radiator or coolant bottle is hot .

Proper towing or lifting equipment is required to pre-
vent damage to your vehicle. Use only tow bars and
other equipment designed for the purpose, following
equipment manufacturer’s instructions. Use of safety
chains is mandatory. Attach a tow bar or other towing
device to main structural members of the vehicle, not
to bumpers or associated brackets. State and local laws
applying to vehicles under tow must be observed. If you must use the accessories (wipers, defrosters,
etc.) while being towed, the ignition must be in the
ON/RUN position, not the ACC position.

7. Reinstall the glove box door. Make sure that thehinges are seated fully as you raise the door. Other-
wise, the door latch will not align properly.
BODY LUBRICATION
Locks and all body pivot points, including such items as
seat tracks, door hinge pivot points and rollers, liftgate,
tailgate, sliding doors and hood hinges, should be
lubricated periodically with a lithium based grease to
assure quiet, easy operation and to protect against rust
and wear. Prior to the application of any lubricant, the
parts concerned should be wiped clean to remove dust
and grit; after lubricating excess oil and grease should
be removed. Particular attention should also be given
to hood latching components to ensure proper func-
tion. When performing other underhood services, the
hood latch, release mechanism and safety catch should
be cleaned and lubricated.
The external lock cylinders should be lubricated twice
a year, preferably in the Fall and Spring. Apply a small
amount of a high quality lubricant directly into the lock
cylinder.
WIPER BLADES
Clean the rubber edges of the wiper blades and the
windshield and rear window periodically with a sponge
or soft cloth and a mild nonabrasive cleaner. This will
remove accumulations of salt, waxes, or road film, and
help reduce streaking and smearing. Operation of the wipers on dry glass for long periods
may cause deterioration of the wiper blades. Always
use washer fluid when using the wipers to remove salt
or dirt from a dry windshield or rear window.
Avoid using the wiper blades to remove frost or ice
from the windshield or rear window. Make sure that
they are not frozen to the glass before turning them on
to avoid damaging the blade. Keep the blade rubber out
of contact with petroleum products such as engine oil,
gasoline, etc.
NOTE:
Life expectancy of wiper blades varies de-
pending on geographical area and frequency of use.
Poor performance of blades may be present with chat-
tering, marks, water lines or wet spots. If any condition
is present please proceed to clean wiper blades with
humid cloth removing any debris that may be affecting
its function.
