Vehicles with misfuel inhibitor
9 Warning
Do not try to open the flap of the
fuel filler neck manually on
vehicles with misfuel inhibitor.
Disregard 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.
The funnel is located in the load
compartment.
Place the funnel in a straight line to
the filler neck and press with slight
force to insert.
Use the funnel to fill the diesel fuel into the filler neck.
After topping-up, put the funnel into
the plastic bag and stow it in the
storage compartment.
