2021 RAM 1500 Owners Manual - SCHEDULED SERVICING — DIESEL ENGINE



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 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 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 Display page 114.

Under no circumstances should oil change intervals exceed 10,000 miles (16,000 km) or 12 months, whichever comes first.

    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 power steering, and fill as needed
    Check function of all interior and exterior lights

    Under normal conditions the diesel fuel filter should be replaced every 20,000 miles (32,000 km) (every other oil change). If the vehicle is being used in severe operating conditions, or In certain geographical areas of the country (Pennsylvania, New York, Ohio, Maryland, West Virginia, Arkansas, Oklahoma, Kansas, Iowa, Missouri and Nebraska) due to fuel cleanliness issues, it’s recommended to replace the fuel filter every 10,000 miles (16,000 km).

ADDITIONAL MAINTENANCE — B6 TO B20 BIODIESEL

    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.
