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, 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 up engine is shut off.
MAINTAINING YOUR VEHICLE 553
Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings. Always
maintain the oil level within the SAFE zone on the dipstick.
Adding 1 quart (0.9 L) of oil when the reading is at the
bottom of the SAFE zone will result in a reading at the top
of the safe zone on these engines.
CAUTION!
Overfilling or underfilling the crankcase will cause
aeration or loss of oil pressure. 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 the "Maintenance Schedule" for further information.
NOTE: Under no circumstances should oil change in-
tervals exceed 10,000 miles (16,000 km) or twelve
months, whichever occurs first.
