CAUTION! (Continued)
• Your vehicle has been built with improved fluids
that protect the performance and durability of your
vehicle and also allow extended maintenance inter-
vals. Do not use chemical flushes in these compo-
nents as the chemicals can damage your engine,
transmission, power steering or air conditioning.
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 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 between the MIN and MAX markings on the
dipstick. Adding one quart of oil when the reading is at the
MIN mark will result in a MAX reading on these engines.
CAUTION!
Overfilling or underfilling will cause oil aeration, or
loss of oil pressure. This could damage your engine.
