In some versions, the needles of the
instruments briefly rotate to the end
position when the ignition is switched
on.
Speedometer
Indicates vehicle speed.
Odometer
The bottom line displays the recordeddistance in miles.
Trip odometer The top line displays the recordeddistance since the last reset.
To reset, press SET/CLR on the turn
signal lever for a few seconds

Some versions are equipped with a
reset knob between speedometer
and Driver Information Centre: to
reset press and hold the knob for a
few seconds with the ignition on.
Trip odometer counts up to a distance
of 2000 miles and then restarts at 0.
Tachometer
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.

Instruments and controls79Fuel 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 79.
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
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.

message is displayed
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 tanks are
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.

80Instruments and controlsEvery 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 might be possible to manually switch back to
liquid gas operation.Seek 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 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.
Turn the thumb wheel clockwise.
If no further gas odour is perceptible
when the manual shut-off valve is
closed, the vehicle can be used in
petrol mode. 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 and lights. Close the
manual shut-off valve on multivalve.

Service display
The engine oil life system lets you
know when to change the engine oil
and filter. Based on driving
conditions, the interval at which an
engine oil and filter change will be
indicated can vary considerably.
To display the remaining engine oil
life duration use turn signal lever

Turn the adjuster wheel to select
Remaining Oil Life .

82Instruments and controlsThe remaining engine oil life duration
is displayed in percent in the Driver

Reset Press SET/CLR on turn signal lever
for several seconds to reset. The
remaining engine oil life duration
page must be active. Switch on
ignition, but not the engine.
The system must be reset every time
the engine oil is changed, to ensure
proper functionality. Seek the
assistance of a workshop.
Next service When the system has calculated that
