WINDSHIELD WIPERS AND WASHERS
Windshield Wipers
The wipers and washers are operated by a switch in the
multifunction control lever. Turn the end of the handle to
select the desired wiper speed.
Intermittent Wiper System
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
into the upper end of the delay range.
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 15 seconds
between cycles, to a cycle every 2 seconds. The delay
intervals will double in duration when the vehicle speed
is 10 mph (16 km) or less.

WARNING!
Sudden loss of visibility through the windshield
could lead to an accident. You might not see other
vehicles or other obstacles. To avoid sudden icing of
the windshield during freezing weather, warm the
windshield with defroster before and during wind-
shield washer use.
Windshield Washers
To use the washer, push in on the washer knob on the end
of the multifunction control lever and hold while spray isdesired. 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, for a period greater than 1 second, while
in the OFF position, the wiper will wipe approximately
three wipes, 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.

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 such as MoparLock
Cylinder Lubricant directly into the lock cylinder.
Windshield Wiper Blades
The rubber edges of the wiper blades and the windshield
should be cleaned periodically with a sponge or soft cloth
and a mild nonabrasive cleaner. This will remove accu-
mulations 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.
Windshield Washers
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 ra-
diator antifreeze).
When refilling the washer fluid reservoir, take some
washer fluid and apply it to a cloth or towel and wipe
clean the wiper blades, 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.

•Off-road or desert operation.
•Extensive operation at high engine speeds (greater
than 2900 rpm) and loads (greater than 70% throttle).
NOTE:Most vehicles are operated under the conditions
listed for ScheduleB.
NOTE:IfANYof these apply to you then change your
coolant every 100,000 miles (160 000 km) or 60 months,
whichever comes first and follow schedule “B” of the
Maintenance Schedulessection of this manual.
Second is Schedule“A”. It is for vehicles that are not
operated under any of the conditions listed under Sched-
uleB.
Use the schedule that best describes your driving condi-
tions. Where time and mileage are listed, follow the
interval that occurs first.
CAUTION!
Failure to perform the required maintenance items
may result in damage to the vehicle.
At Each Stop for Fuel
•Check the engine oil level about 15 minutes after a
fully warmed engine is shut off. Checking the oil level
while the vehicle is on level ground will improve the
accuracy of the oil level reading. Add oil only when
the level is at or below the ADD or MIN mark.
•Check the windshield washer solvent and add if
required. When refilling the washer fluid reservoir,
take some washer fluid and apply it to a cloth or towel
and wipe clean the wiper blades, this will help blade
performance.

•Check the windshield washer solvent and add if
required. When refilling the washer fluid reservoir,
take some washer fluid and apply it to a cloth or towel
and wipe clean the wiper blades, this will help blade
performance.Once a Month
•Check tire pressure and look for unusual wear or
damage.
•Inspect the batteries and clean and tighten the termi-
nals as required.
•Check the fluid levels of coolant reservoir, brake
master cylinder, and transmission and transfer case (if
