Servicing And Maintenance; Scheduled Servicing - Diesel Engine - Jeep WRANGLER 2020 Owner's Manual

SCHEDULED SERVICING — DIESEL ENGINE
Your vehicle is equipped with an automatic oil
change indicator system. The oil change indi-
cator 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 tempera-
tures will influence when the "Oil Change
Required" message is displayed. Severe Operating
Conditions 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).
An authorized dealer will reset the oil change
indicator message after completing the sched-
uled oil change. If a scheduled oil change is
performed by someone other than an autho-
rized dealer, the message can be reset by refer-
ring to the steps described under "Instrument
Cluster Display" in "Getting To Know Your
Instrument Panel" for further information.

SERVICING AND MAINTENANCE

NOTE:
Under no circumstances should oil change
intervals exceed 10,000 miles (16,000 km) or
12 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.
