FIAT PUNTO NATURAL POWER
Do not switch between the
two operating modes whilst
starting the engine
WARNING
In addition, in the case of starting at out-
side temperatures of below around -10°C,
the switching times from Petrol to
Methane increase to allow the pressure
regulator/reduction unit to become warm
enough.
IMPORTANT If the switching takes place
during acceleration or pick-up, there may
be a brief flat spot (fall in power).With the reconfigurable multifunction dis-
play, any system failure is signalled by the
dedicated message and, at the same time,
by the
Rsymbol coming on and the four
methane levels going out. In this case, go
to a Fiat Dealership as quickly as possi-
ble.
