2021 RAM 2500 Owner’s Manual — REFUELING THE VEHICLE — GASOLINE ENGINE

The fuel filler cap (gas cap) is located behind the fuel filler door, on the left side of the vehicle. Open the fuel door and remove the fuel filler cap by turning it counter-clockwise.

Fuel Filler Cap 4

When removing the fuel filler cap, lay the cap tether in the hook, located on the fuel filler door.

When the fuel nozzle “clicks” or shuts off, the fuel tank is full.

Tighten the gas cap until you hear a “clicking” sound. This is an indication that the gas cap is tightened properly. The MIL in the instru- ment cluster may turn on if the gas cap is not secured properly. Make sure that the gas cap is tightened each time the vehicle is refueled.

LOOSE FUEL FILLER CAP MESSAGE

If the vehicle diagnostic system determines that the fuel filler cap is loose, improperly installed, or damaged, a loose gASCAP indicator

will display in the instrument cluster telltale display area page 111. Tighten the fuel filler cap properly and push the RIGHT button to turn off the message. If the problem continues, the message will appear the next time the vehicle is started.
