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.

10W-30 engine oils. Engine Oil Viscosity (SAE Grade) — 2.4L Engine
Mopar SAE 0W-20 engine oil approved to FCA Material
Standard MS-6395 such as Pennzoil, Shell Helix or equiva
-
lent is recommended for all operating temperatures. This
engine oil improves low temperature starting and vehicle
fuel economy.
The engine oil filler cap also shows the recommended engine
oil viscosity for your engine. For information on engine oil
filler cap location, refer to “Engine Compartment” in this
chapter.
Lubricants which do not have both the engine oil certifica -
tion mark and the correct SAE viscosity grade number
should not be used.
Synthetic Engine Oils
You may use synthetic engine oils provided the recom -
mended oil quality requirements are met, and the recom -
mended maintenance intervals for oil and filter changes are
followed.
Synthetic engine oils which do not have both the engine oil
certification mark and the correct SAE viscosity grade
number should not be used.
CAUTION!
Do not use chemical flushes in your engine oil as the
chemicals can damage your engine. Such damage is not
covered by the New Vehicle Limited Warranty.

250 SERVICING AND MAINTENANCE
Materials Added To Engine Oil
The manufacturer strongly recommends against the addi-
tion of any additives (other than leak detection dyes) to the
engine oil. Engine oil is an engineered product and its perfor -
mance may be impaired by supplemental additives.
Disposing Of Used Engine Oil And Oil Filters
Care should be taken in disposing of used engine oil and oil
filters from your vehicle. Used oil and oil filters, indiscrimi -
nately discarded, can present a problem to the environment.
Contact an authorized dealer, service station or govern -
mental agency for advice on how and where used oil and oil
filters can be safely discarded in your area.
Engine Oil Filter
The engine oil filter should be replaced with a new filter at
every engine oil change.
Engine Oil Filter Selection

This manufacturer's engines have a full-flow type disposable oil
filter. Use a filter of this type for replacement. The quality of
replacement filters varies considerably. Only high quality filters
should be used to ensure most efficient service. Mopar engine
oil filters are high quality oil filters and are recommended.

Engine Air Cleaner Filter
Refer to the “Maintenance Plan” in this chapter for the
proper maintenance intervals.
NOTE:
Be sure to follow the “Severe Duty Conditions” maintenance
interval if applicable.
Engine Air Cleaner Filter Selection
The quality of replacement engine air cleaner filters varies
considerably. Only high quality filters should be used to
ensure most efficient service. Mopar engine air cleaner filters
are a high quality filter and are recommended.
WARNING!
The air induction system (air cleaner, hoses, etc.) can
provide a measure of protection in the case of engine
backfire. Do not remove the air induction system (air
cleaner, hoses, etc.) unless such removal is necessary for
repair or maintenance. Make sure that no one is near the
engine compartment before starting the vehicle with the
air induction system (air cleaner, hoses, etc.) removed.
Failure to do so can result in serious personal injury.

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.
