Fuel and Diesel Exhaust Fluid (DEF) Fill Location

  1. Diesel Fuel Filler
  2. DEF Filler

NOTE:

  • When the fuel nozzle “clicks” or shuts off, the fuel tank is full.
  • Tighten the fuel filler cap about a quarter turn until you hear one click. This is an indication that the cap is properly tightened.

CAUTION!

For diesel engines, only use diesel fuel for motor vehicles in accordance with EN 590 European specifications. The use of other products or mixtures may damage the engine beyond repair and consequently void the warranty, due to the damage caused. If you accidentally introduce other types of fuel into the tank, do not start the engine. Empty the tank. If the engine has been run for even an extremely limited amount of time, you must not only drain the fuel tank, but the rest of the supply circuit as well.
