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 status LED shows
the current operating mode.
1 off : petrol operation
1 flashes : checking conditions
for fuel transition to
liquid gas operation.
Illuminates if
conditions are fulfilled.
1 illumi‐ : liquid gas operation
nates
1 flashes 5 : liquid gas tank is
empty or failure in

extin‐
message is displayed
guishes
in the Driver
Information Centre.
If the fuel tank is empty, the engine
will not start.
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, petrol operation is
automatically engaged until the
ignition is switched off.
When switching automatically
between petrol or gas operation, a
brief delay of engine tractive power
may be noticeable.
Every six months, run the petrol tank
down until control indicator I
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.
In extreme situations, the system may
also switch back to petrol mode if the
minimum requirements are not
fulfilled. If conditions allow, it may be
possible to manually switch back to
liquid gas operation.
