52 GETTING TO KNOW YOUR VEHICLE
Windshield Washers
Pull the windshield wiper/washer lever toward the steering
wheel to activate the washers. The wipers will activate auto-
matically for three cycles after the lever is released. Manual High Speed/Mist
Push the lever upward from the off position. The wipers will
operate at high speed to clear off road mist or spray from a
passing vehicle. This operation will continue until the lever
is released. When the lever is released, the wipers will return
to the off position and automatically shut off.
Rear Wiper Operation — If Equipped
Rear Windshield Wiper Operation
Rotate the windshield wiper lever center ring upwards to
operate the rear window wiper as follows:
• In intermittent mode when the front window wiper is not
operating
• In synchronous mode (at half the speed of the front window wiper) when the front window wiper is operating
• In continuous mode while vehicle is in REVERSE
With the windshield wipers on, and REVERSE gear engaged,
rear window wiping will be continuous in the same way.
CAUTION!
• Turn the windshield wipers off when driving through an automatic car wash. Damage to the windshield
wipers may result if the wiper control is left in any
position other than off.
• In cold weather, always turn off the wiper switch and allow the wipers to return to the park position before
turning off the engine. If the wiper switch is left on and
the wipers freeze to the windshield, damage to the
wiper motor may occur when the vehicle is restarted.
• Always remove any buildup of snow that prevents the windshield wiper blades from returning to the off posi -
tion. If the windshield wiper control is turned off and
the blades cannot return to the off position, damage to
the wiper motor may occur.

246 SERVICING 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 therange 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 crosshatch mark
-
ings on the dipstick.
Adding 1 quart (1.0 liters) 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 windshield and rear window washers share the same fluid
reservoir. The fluid reservoir is located in the front of the engine
compartment. Be sure to check the fluid level in the reservoir at
regular intervals. Fill the reservoir with windshield washer
solvent (not radiator antifreeze) and operate the system for a
few seconds to flush out the residual water.
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. CAUTION!
Overfilling or underfilling the crankcase will cause
aeration or loss of oil pressure. This could damage your
engine.

252 SERVICING 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 Fall and Spring. Apply a small amount of a
high quality lubricant, such as Mopar Lock Cylinder Lubri-
cant directly into the lock cylinder.
Windshield Wiper Blades
Clean the rubber edges of the wiper blades and the wind -
shield 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 petro -
leum 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.

SERVICING AND MAINTENANCE 253
Wiper Service Position
If it is necessary to lift the blade from the windshield (In the
event of snow or blade replacement) Proceed as directed:
1. Rotate the end of the multifunction lever to the OFF posi-
tion.
2. Turn the ignition to the MAR-ON position then to STOP.
3. After turning the ignition to the STOP, within two minutes move the right stalk upward, into the unstable
(“anti-panic”) position, for at least half of a second. The
windshield wiper then executes part of a stroke; at each
command, approximately 1/3 of a normal wiper stroke is
triggered.
NOTE:
The previous operation can be repeated up to three times. In
order to move the blades to the most suitable position.
4. Lift the blade from the windshield and proceed with the required operation. 5. Carefully lower the blade, bringing it back in contact with
the windshield.
6. Bring the blade to the initial rest position, turning the ignition to MAR-ON.
NOTE:
Do not operate the wiper with the blades lifted from the
windshield.
Exhaust System
The best protection against carbon monoxide entry into the
vehicle body is a properly maintained engine exhaust
system.
If you notice a change in the sound of the exhaust system; or
if the exhaust fumes can be detected inside the vehicle; or
when the underside or rear of the vehicle is damaged; have
an authorized technician inspect the complete exhaust
system and adjacent body areas for broken, damaged, dete -
riorated, or mispositioned parts. Open seams or loose
connections could permit exhaust fumes to seep into the
passenger compartment. In addition, have the exhaust
system inspected each time the vehicle is raised for lubrica -
tion or oil change. Replace as required.
