tank, the top-up quantity may be less
than the specified tank capacity.
Fuel selector Liquid gas operation, LPG
Pressing LPG switches between
petrol and liquid gas operation as
soon as the required parameters (coolant temperature, gas
temperature and minimum engine
speed) have been reached. The
requirements are usually fulfilled after
approximately 60 seconds
(depending on exterior temperature)
and the first firm press on the
accelerator. The LED status shows

or failure in liquid gas
system. A message is
displayed in the Driver
Information Centre. The
vehicle is in petrol
operation.
The selected fuel mode is stored and reactivated at the next ignition cycle if
conditions allow.
As soon as the liquid gas tank is
empty, a warning message is
displayed in the Driver Information
Centre and the LED in the button
flashes rapidly. Petrol operation is
automatically engaged.
When switching automatically
between petrol or gas operation, a
brief delay of engine tractive power
may be noticeable.
When petrol fuel tank is empty, the
engine will not start.
Every six months, run the petrol tank
down until control indicator Y
illuminates, then refuel. This helps
maintain fuel quality and system
function for petrol operation.
Fill the tank completely at regular
intervals to prevent corrosion in the
tank.
Faults and remedies
If gas mode is not possible, check the following:
● Is there enough liquid gas present?
● Is there enough petrol present for
starting?
Due to extreme temperatures in
combination with the gas
composition, it may take slightly
longer before the system switches
from petrol to gas mode.

(maximum fill level).
Release button on filling system and
the filling process stops. 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

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.
The multivalve on the liquid gas tank
automatically limits the fill quantity. If
a larger quantity is added, we
recommend not exposing the vehicle
to the sun until the excess amount
has been used up.
Fuel filler cap
Only use genuine fuel filler caps. Diesel-engined vehicles have special fuel filler caps.
