Instruments and controls

If the natural gas tanks are not
refuelled, the system must be
manually switched to petrol operation
before the engine is started up again.
This will prevent damage to the
catalytic converter (overheating
caused by irregular fuel supply).
If the selector switch is operated
several times within a short time
a switchover block is activated. The
engine remains in the current
operating mode. The block remains
active until the ignition is switched off.
A slight loss of power and torque can
be expected in petrol operation. You
must therefore adapt your driving
style (e.g. during overtaking
manoeuvres) and vehicle loads (e.g.
towing loads) accordingly.
Every six months run the petrol tank
down until control indicator Y
illuminates and refuel. This is
necessary to maintain fuel quality as
well as system function necessary for
petrol operation.
Fill the tank completely at regular
intervals to prevent corrosion in the
tank. Service display
The message InSP appears when it
is time for servicing. Further

Control indicators
The control indicators described are
not present in all vehicles. The
description applies to all instrument
versions. When the ignition is
switched on, most control indicators
will
illuminate briefly as a functionality
test. The control indicator colours mean:
Red = Danger, important
reminder,
Yellow = Warning, information, fault,
Green = Confirmation of activation,
Blue = Confirmation of activation.
