Refuelling the vehicle
Environment!
When refuelling, make sure that no fuel flows out next to the
tank filling opening! Never refuel up to the upper edge of the fil-
ling opening - the fuel expands under heat and can overflow!
Use a suitable container to collect any spilt fuel and dispose of it
according to local or national environment protection regulati-
ons!
Open the tank flap and unlock lockable tank lock as applicable
Immerse the nozzle of the fuel pump as deep as possible in the tank to
prevent splashing or spilling diesel fuel
After refuelling, replace the tank lock and turn it to the right until it audi-
bly locks into place
Lock the tank lock and close the tank flap as applicable
Caution!
If petrol or supergrade petrol was refuelled by mistake, the
engine may not be started to avoid damage.
Have the fuel system drained by an authorised workshop with
consideration of the environmental standards and fill again
with diesel fuel!
Cleaning the fuel tank
Environment!
Use a suitable container to collect any spilt fuel and dispose of it
according to local or national environment protection regulati-
ons!
Important!
Drain the condensation water from the fuel tank at regular intervals,
at the latest every 600 operating hours or at the latest every
year .
Deposits of dirt particles and water in the tank cannot be entirely avoided.
The fuel tank should therefore be cleaned occasionally, particularly before
winter operation.
Clean the fuel tank when the fuel level in the tank is as low as possible!
Clean the fuel tank as follows:
Place a drip pan under the fuel tank
Open the tank lock
Remove the drain plug (see figure 96)
Flush out the fuel tank with fuel, several times if necessary
Turn in the drain plug with a new sealing ring
Fill the tank
Check the drain plug for tightness
Bleed the fuel system as required (see page 4-6)
