108Instruments and controlsCaution
If the needle is in the red warning
zone, the maximum permitted
engine speed is exceeded. Engine at risk.
Fuel gauge
Displays the fuel level or gas level in
the tank depending on the operation
mode.
Control indicator i illuminates if the
level in the tank is low. Refuel
immediately if it flashes.
During liquid gas operation, the
system automatically switches over to
petrol operation when gas tanks are
empty 3 108.
Never run the tank dry.
Because of the fuel remaining in the
tank, the top-up quantity may be less
than the specified tank capacity.
Fuel selector
Press LPG to switch between petrol
and liquid gas operation. The LED
1 status shows the current operating
mode.

212Driving and operating
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
around 60 seconds (depending on
exterior temperature) and the first firm press on the accelerator. The LED
status shows the current operating
mode.1 off=petrol operation1 illumi‐
nates=liquid gas operation1 flashes=no switching is
possible, one type of
fuel is empty
As soon as the liquid gas tanks are empty, petrol operation is
automatically engaged until the
ignition is switched off.
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.
Seek the assistance of a workshop in the event of all other faults.Caution
Repairs and adjustments may onlybe made by trained specialists in
order to maintain the safety and
warranty on the LPG system.
Liquid gas is given a particular odour
(odorised) so that any leaks can be
detected easily.
9 Warning
If you smell gas in the vehicle or in
the immediate vicinity, switch to petrol mode immediately. No
smoking. No naked flames or
ignition sources.
If possible, close the manual shut-off
valve on the multivalve. The
multivalve is located on the liquid gas
tank in the load compartment,
underneath the rear floor cover.
