CAUTION! (Continued)
•Your vehicle has been built with improved fluids
that protect the performance and durability of
your vehicle and also allow extended maintenance
intervals. Do not use chemical flushes in these
components as the chemicals can damage your
engine, transmission, power steering or air condi-
tioning. Such damage is not covered by the New
Vehicle Limited Warranty. If a flush is needed
because of component malfunction, use only the
specified fluid for the flushing procedure.
Engine Oil
Checking Oil Level
To assure 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 afully warmed engine is shut off. Do not check oil level
before starting the engine after it has sat overnight.
Checking engine oil level when the engine is cold will
give you an incorrect reading.
Checking the oil while the vehicle is on level ground and
only when the engine is hot, will improve the accuracy of
the oil level readings. Maintain the oil level between the
range markings on the dipstick. The range markings will
consist of a crosshatch zone that says SAFE or a cross-
hatch zone that says MIN at the low end of the range and
MAX at the high end of the range. Adding 1 qt (1L) of oil
when the reading is at the low end of the indicated range
will result in the oil level at the full end of the indicator
range.

CAUTION!
Do not overfill the engine. Overfilling the engine as
indicated by the range markings, as described above,
on the engine oil dipstick will cause oil aeration,
which can lead to loss of oil pressure and an increase
in oil temperature. This could damage your engine.
Change Engine Oil
The oil change indicator system will remind you that it is
time to take your vehicle in for scheduled maintenance.
Refer to “Maintenance Schedule” for further information.
NOTE: Under no circumstances should oil change
intervals exceed 6,000 miles (10 000 km) or six months,
whichever occurs first.
Engine Oil Selection
For best performance and maximum protection for all
engines under all types of operating conditions, themanufacturer recommends engine oils that are API Cer-
tified and meet the requirements of Chrysler Material
Standard MS-6395.
American Petroleum Institute (API) Engine Oil

CAUTION!
Do not use chemical flushes in your engine oil as the
