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 crosshatch
markings on the dipstick.
Adding 1 quart (1.0 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

Windshield Washer Fluid Cap

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 washer fluid.
When refilling the washer fluid reservoir, take
some washer fluid, 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.
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 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.
WARNING!
Battery fluid is a corrosive acid solution and
can burn or even blind you. Do not allow
battery fluid to contact your eyes, skin, or
clothing. Do not lean over a battery when
attaching clamps. If acid splashes in eyes or
on skin, flush the area immediately with large
amounts of water Ú

Synthetic Engine Oils
You may use synthetic engine oils provided the
recommended oil quality requirements are met,
and the recommended 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.
Materials Added To Engine Oil
The manufacturer strongly recommends against
the addition of any additives (other than leak
detection dyes) to the engine oil. Engine oil is an
engineered product and its performance 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, indiscriminately discarded, can present a
problem to the environment. Contact an authorized dealer, service station or
governmental 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.

SERVICING AND MAINTENANCE335
When inspecting accessory drive belts, small
cracks that run across the ribbed surface of a belt
from rib to rib, are considered normal. These are
not a reason to replace belt. However, cracks
running along a rib (not across) are not normal. Any
belt with cracks running along a rib must be
replaced. Also, have the belt replaced if it has
excessive wear, frayed cords, or severe glazing.

Accessory Belt (Serpentine Belt)

Conditions that would require replacement:
Rib chunking (one or more ribs has separated
from belt body)
Rib or belt wear
Longitudinal belt cracking (cracks between two
ribs)
Belt slips
“Groove jumping" (belt does not maintain
correct position on pulley)
Belt broken
NOTE:Identify and correct problem before new belt is
installed
Noise (objectionable squeal, squeak, or rumble
is heard or felt while drive belt is in operation).
Some conditions can be caused by a faulty
component such as a belt pulley. Belt pulleys
should be carefully inspected for damage and
proper alignment.
Belt replacement on some models requires the
use of special tools; we recommend having your
vehicle serviced at an authorized dealer.
AIR CONDITIONER MAINTENANCE
For best possible performance, your air conditioner
should be checked and serviced by an authorized
dealer at the start of each warm season. This
service should include cleaning of the condenser
fins and a performance test. Drive belt tension
should also be checked at this time.
WARNING!
Use only refrigerants and compressor lubri -
cants approved by the manufacturer for your
air conditioning system. Some unapproved
refrigerants are flammable and can explode,
injuring you. Other unapproved refrigerants or
lubricants can cause the system to fail,
requiring costly repairs. Refer to Warranty
Information located online, for further
warranty information.
The air conditioning system contains refrig -
erant under high pressure. To avoid risk of
personal injury or damage to the system,
adding refrigerant or any repair requiring lines
to be disconnected should be done by an
experienced technician.

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.
