GETTING TO KNOW YOUR VEHICLE57
WINDSHIELD WIPER OPERATION

Rotate the end of the lever upward, to the first
detent past the intermittent settings for low-speed
wiper operation. Rotate the end of the lever upward
to the second detent past the intermittent settings
for high-speed wiper operation.

Windshield Wiper/Washer Lever

Intermittent Wipers
The intermittent feature of this system was
designed for use when weather conditions
make a single wiping cycle, with a variable
pause between cycles, desirable. For maximum
delay between cycles, rotate the control knob
upward to the first detent.
The delay interval decreases as you rotate the
knob until it enters the low continual speed position. The delay can be regulated from a
maximum of about 18 seconds between cycles,
to a cycle every one second. The delay intervals
will double in duration when the vehicle speed
is 10 mph (16 km/h) or less.
Windshield Washers
To use the windshield washer, push the washer
knob, located on the end of the multifunction
lever, inward to the second detent. Washer fluid
will be sprayed and the wiper will operate for
two to three cycles after the washer knob is
released from this position.
If the washer knob is depressed while in the
delay range, the wiper will operate for several
seconds after the washer knob is released.
It will then resume the intermittent interval
previously selected. If the washer knob is
pushed while in the off position, the wiper will
turn on and cycle approximately three times
after the wash knob is released.
To prevent freeze-up of your windshield washer
system in cold weather, select a solution or
mixture that meets or exceeds the temperature
range of your climate. This rating information
can be found on most washer fluid containers. Mist
When a single wipe to clear off road mist or
spray from a passing vehicle is needed, push
the washer knob, located on the end of the
multifunction lever, inward to the first detent
and release. The wipers will cycle one time and
automatically shut off.
NOTE:
The mist feature does not activate the washer
pump; therefore, no washer fluid will be sprayed
on the windshield. The wash function must be
used in order to spray the windshield with
washer fluid.
For information on wiper care and replacement,
see Ú
page 380.
WARNING!

Sudden loss of visibility through the windshield
could lead to a collision. You might not see other
vehicles or other obstacles. To avoid sudden icing
of the windshield during freezing weather, warm
the windshield with the defroster before and
during windshield washer use.

366SERVICING AND MAINTENANCE
CHECKING OIL LEVEL
To ensure proper engine lubrication, the engine
oil must be maintained at the correct level.
Check the oil level at regular intervals, such as
every fuel stop. The best time to check the
engine oil level is about five minutes after a fully
warmed up engine is shut off.
Checking the oil while the vehicle is on level
ground will improve the accuracy of the oil level
readings.
There are four possible dipstick types:
Crosshatched zone.
Crosshatched zone marked SAFE.
Crosshatched zone marked with MIN at the
low end of the range and MAX at the high end
of the range.
Crosshatched zone marked with dimples at
the MIN and the MAX ends of the range.
NOTE:
Always maintain the oil level within the cross -
hatch markings on the dipstick. Adding 1 quart (1 liter) of oil when the reading is
at the low end of the dipstick range will raise the
oil level to the high end of the range marking.
ADDING WASHER FLUID

The fluid reservoir is located under the hood and
should be checked for fluid level at regular
intervals. Fill the reservoir with windshield
washer solvent only (not radiator antifreeze).
When refilling the washer fluid reservoir, take
some washer fluid and apply it to a cloth or towel
and wipe the wiper blades clean. This will help
blade performance.

To prevent freeze-up of your windshield washer
system in cold weather, select a solution or
mixture that meets or exceeds the temperature
range of your climate. This rating information
can be found on most washer fluid containers.
After the engine has warmed up, operate the
defroster for a few minutes to reduce the
possibility of smearing or freezing the fluid on
the cold windshield. Windshield washer solution
used with water as directed on the container,
aids cleaning action, reduces the freezing point
to avoid line clogging, and is not harmful to
paint or trim.
MAINTENANCE-FREE BATTERY

Your vehicle is equipped with a maintenance-free
battery. You will never have to add water, and
periodic maintenance is not required.

CAUTION!
Overfilling or underfilling the crankcase will
cause oil aeration or loss of oil pressure.
This could damage your engine.
WARNING!
Commercially available windshield washer
solvents are flammable. They could ignite and
burn you. Care must be exercised when filling
or working around the washer solution.

380SERVICING AND MAINTENANCE
BODY LUBRICATION
Locks and all body pivot points, including such
items as seat tracks, door hinge pivot points
and rollers, liftgate, tailgate, decklid, sliding
doors and hood hinges, should be lubricated
periodically with a lithium-based grease, such
as Mopar Spray White Lube to ensure 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 function. 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 Autumn and
Spring. Apply a small amount of a high quality
lubricant, such as Mopar Lock Cylinder
Lubricant directly into the lock cylinder.
WINDSHIELD WIPER BLADES
Clean the rubber edges of the wiper blades and
the windshield periodically with a sponge or soft
cloth and a mild nonabrasive cleaner. This will
remove accumulations of salt or road film.
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.
Avoid using the wiper blades to remove frost or
ice from the windshield. Keep the blade rubber
out of contact with petroleum products such as
engine oil, gasoline, etc.
NOTE:
Life expectancy of wiper blades varies
depending on geographical area and frequency
of use. Poor performance of blades may be
present with chattering, marks, water lines
or wet spots. If any of these conditions are
present, clean the wiper blades or replace as
necessary. The wiper blades and wiper arms should be
inspected periodically, not just when wiper
performance problems are experienced.
This inspection should include the following
points:
Wear or uneven edges
Foreign material
Hardening or cracking
Deformation or fatigue
If a wiper blade or wiper arm is damaged,
replace the affected wiper arm or blade with a
new unit. Do not attempt to repair a wiper arm
or blade that is damaged.
Wiper Blade Removal/Installation
CAUTION!
Do not allow the wiper arm to spring back
against the glass without the wiper blade in
place or the glass may be damaged.
