2022 Jeep Wrangler Diesel Scheduled Service User Manual
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, and extremely hot or cold ambient temperatures will influence when the “Oil Change Required” message is displayed. 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 scheduled oil change. If a scheduled oil change is performed by someone other than an authorized dealer, to reset the message Ú page 120.
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, open the filter cap approximately six turns until the cap o-ring is visible and stop. Wait five minutes with the cap in this position to allow dirty engine oil to drain back into the engine. After five minutes, the cap and filter assembly can be removed and discarded. When installing the new oil filter cartridge assembly, ensure the cap is tightened to the specified torque to prevent low oil pressure conditions.
Once A Month Or Before A Long Trip
- Check engine oil level
- Check windshield washer fluid level
- Check the tire pressures and look for unusual wear or damage
- Check the fluid levels of the coolant reservoir, brake master cylinder, and fill as needed
- Check the function of all interior and exterior lights

Refer to the maintenance plan for the required maintenance intervals.
At Every Oil Change Interval As Indicated By Oil Change Indicator System:

- Rotate the tires. Rotate at the first sign of irregular wear, even if it occurs before the oil indicator system turns on.

ADDITIONAL MAINTENANCE — B6 TO B20 BIODIESEL
NOTE
- Under no circumstances should oil change intervals exceed 8,000 miles (12,875 km) or six months, whichever comes first when using biodiesel blends greater than 5% (B5).
- The owner is required to monitor mileage for B6-B20 biodiesel, the automatic oil change indicator system does not reflect the use of biofuels.
- Fuel filter change interval is maintained at every second oil change. This is especially important with biodiesel usage. For more information on using biodiesel Ú page 421.
