Checking the oil while the vehicle is on level ground, and
approximately five minutes after a fully warmed engine
is shut off, will improve the accuracy of the oil level
readings. Maintain the oil level between the range mark-
ings on the dipstick. The safe range is indicated by a
crosshatch zone. Adding 1 quart (0.9 Liters) 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 with oil. Overfilling the
engine with oil will cause oil aeration, which can
lead to loss of oil pressure and an increase in oil
temperature. This loss of oil pressure and increased
oil temperature 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 informa-
tion.
NOTE:Under no circumstances should oil change inter-
vals exceed 10,000 miles (16,000 km), twelve months or
350 hours of engine run time, whichever comes first. The
350 hours of engine run or idle time is generally only a
concern for fleet customers.
Engine Oil Selection
For best performance and maximum protection for tur-
bocharged engines under all types of operating condi-
tions, the manufacturer recommends synthetic engine
oils that are API Certified and meet the requirements of
FCA Material Standard MS-12991.
