Instruments and controls 83
Fuel gauge
Displays the fuel level in the fuel tank.
Control indicator
Y
illuminates if the
level in the tank is low. Refuel
immediately if it flashes.
Fuel selector
Pressing button
Y
switches between
petrol and natural gas operation.
Switching is not possible at high loads
(e.g. strong acceleration, running at
full throttle). The LED status shows
the current operating mode.
Natural gas
operation
= LED off.
Petrol operation = LED illuminates.
As soon as the natural gas tanks are
empty, petrol operation is
automatically engaged until the
ignition is switched off.
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.
