Pressing Y switches between petrol
and natural gas operation. Switching
is not possible at high loads (e.g.
powerful acceleration, driving at full
throttle). The LED status shows the
current operating mode.

nates:petrol operation1 flashes:no switching is
possible, one type of
fuel is emptyAs soon as the natural gas tank is
empty, petrol operation is
automatically engaged until the
ignition is switched off.
If the natural gas tank is not refuelled, the system must be manually
switched to petrol operation before
the engine is restarted. 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 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.
Every six months run the petrol tank
down until control indicator Y
illuminates, then refuel. This isnecessary 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.
Notice
Natural gas tanks (Type IV) consist
of lightweight fibre reinforced plastic.
After a collision behind the front
seats or overrunning of objects
which impact the underbody of the vehicle the natural gas tanks must
be checked. We recommend an
Opel Repairer authorised for
servicing natural gas vehicles.
