Besides those maintenance items specified in
the fixed "Service and Warranty Handbook",
there are other components which may require
servicing or replacement in the future.
CAUTION!
• Failure to properly maintain your vehicle or
perform repairs and service when neces-
sary could result in more costly repairs,
damage to other components or negatively
impact vehicle performance. Immediately
have potential malfunctions examined by
an authorized dealer or qualified repair
center.
• 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
CAUTION! (Continued)
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 a fully
warmed engine is shut off.
Checking the oil while the vehicle is on level
ground will improve the accuracy of the oil level
readings. Maintain the oil level in the "SAFE"
range. Adding 1.0 qt (.95 L) of oil when the
reading is at the bottom of the "SAFE" range will
result in an oil level at the top of the "SAFE"
range on these engines.
(Continued)
CAUTION!
Overfilling or underfilling will cause oil aera-
tion or loss of oil pressure. This could dam-
age your engine.
Change Engine Oil
The oil change indicator system will remind you
that it is time to take your vehicle in for sched-
uled maintenance. Refer to "Service and War-
ranty Handbook" 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
under all types of operating conditions, the
manufacturer only recommends full synthetic
engine oils that meet the requirements of
Chrysler Material Standard MS-12633 or ACEA
