SERVICING AND MAINTENANCE
SCHEDULED SERVICING
Your vehicle is equipped with an engine oil change
indicator system. This system will alert you when it is time
to change your engine oil by displaying the words
“Oil Change Due” in your instrument cluster display. The
engine oil change indicator system is duty cycle based,
which means the engine oil change interval may fluctuate
depending on your personal driving style. Failure to
change the engine oil per the maintenance schedule can
result in internal engine damage.
An authorized dealer will reset the oil change indicator
message after completing the scheduled oil change. If a
scheduled oil change is performed by someone other than
an authorized dealer, the message can be reset by
referring to the steps described under instrument cluster
For gasoline engines, under no circumstances should oil
change intervals exceed 8,000 miles (13,000 km),
12 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.
For diesel engines, under no circumstances should oil
change intervals exceed 15,000 miles (24,000 km) or
12 months, whichever comes first or sooner if prompted
by the oil change indicator system.
NOTE:
It is recommended that every 3,000 miles (4,800 km),
check the engine oil level at least 30 minutes after a
fully warmed engine is shut off. Checking the oil level
while the vehicle is on level ground will improve the
accuracy of the oil level reading. Add oil only when the
level is at or below the ADD or MIN mark.
Severe service (high ambient temperature, short trips,
heavy loading, trailer towing, off-road, or law enforce
-
ment use) may reduce oil change intervals.
For Diesel Engines, configured with optional B20
capability are operated with greater than 5% levels of
biodiesel, the oil change interval must not exceed
12,500 miles (20,000 km) or 400 hours, whichever
comes first under any circumstances. See the Fuel
Requirements section for more information regarding
operation with biodiesel blend (B6-B20) fuel meeting
ASTM specification D-7467.
CAUTION!
Failure to perform the required maintenance items may
result in damage to the vehicle.
