Switching is not possible at high loads
(e.g. powerful acceleration, driving at
full throttle).
If the selector switch is operated
several times within a short time, a
switchover inhibitor is activated. The
engine remains in the current
operating mode. The inhibitor
remains active until the ignition is
switched off.
A slight loss of power and torque can
be expected during petrol operation.
You must therefore adapt your driving style, e.g. during overtaking
manoeuvres and high vehicle loads
(e.g. towing loads) accordingly.
The vehicle consumes petrol when
starting the engine and even when in certain natural gas operating modes.The petrol consumption in natural gas
operating mode can vary depending
on driving behaviour (e.g. high load or towing). In case of a low fuel level, a
corresponding message is displayed as a reminder to refuel.
Notice
Always ensure that there is enough
petrol in the tank.
