instruments briefly rotate to the end
position when the ignition is switched
on.
Speedometer

Instruments and controls103Tachometer
Displays the engine speed.
Drive in a low engine speed range for each gear as much as possible.
Caution
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 content
(LPG or CNG) in the tank depending
on the operation mode.
Number of LEDs displayed shows the level in the respective fuel tank. 8
LEDs means fuel tank is full.
During gas operation, the level in the gas tank is displayed.
Low fuel indication
One remaining LED illuminating white indicates that the fuel level is low.
If the LED changes to red and Y
illuminates yellow, refuel the tank soon.
If the LED illuminates red and Y
flashes yellow, refuel immediately.
Never run the fuel tank dry.
The arrow indicates the vehicle side
where the fuel filler flap is located.
Because of the fuel remaining in the
tank, the top-up quantity may be less
than the specified tank capacity.
During gas operation, the system automatically switches over to petrol
operation when gas tanks are empty
3 104.
Instruments and controls105Liquid 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.

guishes:liquid gas tank is
empty or failure in
liquid gas system. A
message is displayed
in the Driver
Information Centre.
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.
When petrol fuel tank is empty, the
engine will not start.
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.
106Instruments and controlsSeek the assistance of a workshop in
the event of all other faults.Caution
Repairs and adjustments may only be 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 the gas odour persists, do not start
the engine. Have the cause of the
fault remedied by a workshop.
When using underground car parks,
follow the instructions of the operator
and local laws.
Notice
In the event of an accident, switch off
the ignition.
