408SERVICING 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 (1.0 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.
NOTE:
It is possible for your oil level to be slightly
higher than a previous check. This would be due
to diesel fuel that may temporarily be in the
crankcase due to operation of the diesel partic
-
ulate filter regeneration strategy (if equipped).
This fuel will evaporate out under normal oper -
ation.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.
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.

AUTOMATIC TRANSMISSION
Special Additives
FCA strongly recommends against using any
special additives in the transmission. Automatic
Transmission Fluid (ATF) is an engineered
product and its performance may be impaired
by supplemental additives. Therefore, do not
add any fluid additives to the transmission.
Avoid using transmission sealers as they may
adversely affect seals.
Fluid Level Check
The fluid level is preset at the factory and does
not require adjustment under normal operating
conditions. Routine fluid level checks are not
required, therefore the transmission has no
dipstick. An authorized dealer can check your
transmission fluid level using special service
tools. If you notice fluid leakage or transmission
malfunction, visit an authorized dealer
immediately to have the transmission fluid level
checked. Operating the vehicle with an
improper fluid level can cause severe
transmission damage.
Fluid And Filter Changes
Under normal operating conditions, the fluid
installed at the factory will provide satisfactory
lubrication for the life of the vehicle.
Routine fluid and filter changes are not
required. However, change the fluid and filter if
the fluid becomes contaminated (with water,
etc.), or if the transmission is disassembled for
any reason.
Selection Of Lubricant
It is important to use the proper transmission
fluid to ensure optimum transmission performance and life. Use only the
recommended transmission fluid
Úpage 478.
It is important to maintain the transmission fluid
at the correct level using the recommended
fluid. No chemical flushes should be used in any
transmission; only the approved lubricant
should be used.
REAR AXLE AND 4X4 FRONT DRIVING
A
XLE FLUID LEVEL
For normal service, periodic fluid level checks
are not required. When the vehicle is serviced
for other reasons the exterior surfaces of the
axle assembly should be inspected. If gear oil
leakage is suspected inspect the fluid level
Ú page 478. This inspection should be made
with the vehicle in a level position.
The fluid level should be even with the bottom
of the fill hole (within 1/4 in (6.4 mm) of edge of
hole) for the front axle and rear axle.
CAUTION!
Do not use chemical flushes in your
transmission as the chemicals can damage
your transmission components. Such damage
is not covered by the New Vehicle Limited
Warranty.
CAUTION!
If a transmission fluid leak occurs, visit an
authorized dealer immediately. Severe
transmission damage may occur. An
authorized dealer has the proper tools to
adjust the fluid level accurately.CAUTION!
Using a transmission fluid other than the
manufacturer’s recommended fluid may
cause deterioration in transmission shift
quality and/or torque converter shudder
