Scheduled Servicing - Diesel Engine - Jeep Grand Cherokee 4x2 2019 Supplement Manual

48 SERVICING AND MAINTENANCE
Scheduled Servicing — Diesel Engine
Your vehicle is equipped with an automatic oil change
indicator system. The oil change indicator system will
remind you that it is time to take your vehicle in for
scheduled maintenance.
Based on engine operation conditions, the oil change
indicator message will illuminate. This means that service
is required for your vehicle. Operating conditions such as
frequent short-trips, trailer tow, extremely hot or cold
ambient temperatures will influence when the "Oil Change
Required" message is displayed. Severe Operating Condi-
tions will cause the change oil message to illuminate more
frequently. Have your vehicle serviced as soon as possible,
within the next 500 miles (805 km).
Your 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
your authorized dealer, the message can be reset by
referring to the steps described under "Instrument Cluster
Display" in "Getting To Know Your Instrument Panel" for
further information.
NOTE: Under no circumstances should oil change inter-
vals exceed 10,000 miles (16,000 km) or twelve months,
whichever comes first.
Engine Oil Filter Replacement
Residual oil in the housing may spill from the housing
when the new filter is installed if the residual oil is not
either removed from the housing or enough time has not
elapsed to allow the oil to drain back into the engine. When
servicing the oil filter on this engine, carefully remove the
filter and use a suction gun to remove any residual oil left
in the housing or wait about 30 minutes for the oil to drain
back into the engine.
Once A Month Or Before A Long Trip:
• Check engine oil level
• Check windshield washer fluid level
• Check the tire inflation pressures and look for unusual
wear or damage
• Check the fluid levels of the coolant reservoir, brake
master cylinder, and fill as needed
