204Driving and operating
The fuel filler cap can be retained in
the bracket on the fuel filler flap.
To refuel, fully insert the pump nozzle
and switch it on.
After the automatic cut-off, the tank can be topped up by operating the
pump nozzle a maximum of two more
times.
Caution
Wipe off any overflowing fuel
immediately.
To close, turn the fuel filler cap
clockwise until it clicks.
Close the flap and allow it to engage.
Vehicles with misfuel inhibitor9 Warning
Do not try to open the flap of the
fuel filler neck manually on
vehicles with misfuel inhibitor.
Disregarding this could lead to
trapping of the fingers.
Vehicles with a selective catalytic
reduction system are equipped with a
misfuel inhibitor.
The misfuel inhibitor ensures that the flap of the fuel filler neck can only be
opened by using a nozzle for diesel
fuel or a funnel for emergency
refilling.
Turn the fuel filler cap slowly
anticlockwise.
The cap can be retained in the
bracket on the fuel filler flap.
Place the nozzle in a straight line to the filler neck and press with slight
force to insert.
In case of an emergency, refill with a
canister. A funnel must be used to
open the cap of the filler neck.

206Driving and operating
Unscrew protective cap from the filler
neck.
Screw the required adapter hand-
tight onto the filler neck.
ACME Adapter: Screw the nut of the
filling nozzle onto the adapter. Press
locking lever on filler nozzle down.
DISH filler neck: Place the filler nozzle
into the adapter. Press locking lever
on filler nozzle down.
Bayonet filler neck: Place filler nozzle
on the adapter and turn clockwise or
anticlockwise through one quarter
turn. Pull locking lever of filler nozzle
fully.
EURO filler neck: Press the filler
nozzle onto the adapter until it
engages.
Press the button at the liquid gas
supply point. The filling system stops
or begins to run slowly when 80% of
the tank volume is reached
(maximum fill level).
Release button on filling system to
stop the filling process. Release the
locking lever and remove the filler
nozzle. A small quantity of liquid gas
may escape.
Remove adapter and stow in vehicle. Fit protective cap to prevent the
penetration of foreign bodies into the
filler opening and the system.9 Warning
Due to the system design, an
escape of liquid gas after
releasing the locking lever is
unavoidable. Avoid inhaling.
9 Warning
The liquid gas tank should only be
filled to 80% capacity, for safety
reasons.

Driving and operating211Fitting the coupling ball bar
Disengage and fold down the socket.Remove the sealing plug from the
opening for the coupling ball bar and
stow it.
Checking the tensioning of the
coupling ball bar
● Red marking on rotary knob must
point towards green marking on
coupling ball bar.
● The gap between the rotary knob
and the coupling ball bar must be approx. 6 mm.
● The key must be in position c.
Otherwise, the coupling ball bar must be tensioned before being inserted:
● Unlock coupling ball bar by turning key to position c.
● Pull out rotary knob and turn
clockwise as far as it will go.
Inserting the coupling ball bar
Page 214 of 293

212Driving and operatingInsert the tensioned coupling ball bar
in the opening and push firmly
upwards until it audibly engages.
The rotary handle snaps back into its
original position, resting against the
coupling ball bar without a gap.9 Warning
Do not touch rotary handle during
insertion.
Lock the coupling ball bar by turning
the key to position e. Remove the key
and close the protective flap.
Eye for break-away stopping cable
Attach breakaway stopping cable to
eye.
Check that the coupling ball bar is correctly installed
● Green marking on rotary knob must point towards green
marking on coupling ball bar.
● There must be no gap between the rotary handle and the
coupling ball bar.
● The coupling ball bar must be firmly engaged in the opening.
● The coupling ball bar must be locked and the key removed.9Warning
Towing a trailer is permitted only
when a coupling ball bar is fitted correctly. If the coupling ball bardoes not engage correctly, seekthe assistance of a workshop.
Dismounting the coupling ball bar
Open the protective flap and turn the
key to position c to unlock the
coupling ball bar.
Pull out rotary handle and turn
clockwise as far as it will go. Pull out coupling ball bar downwards.
Insert sealing plug in opening. Fold away socket.
