Notes for the Diesel Engine Starting
(Diesel only)
With cold engine and external
temperature below 0°C ignition may
be delayed a few seconds in order to
allow the spark plugs to pre-heat. In
this case the amber light
related message will illuminate on the
TFT display and will stay on for a few
seconds after the engine has started.
Cold Weather Precautions (Diesel
only)
If the outside temperature is very low,
the diesel fuel thickens due to the
formation of paraffin clots and could
clog the diesel filter. In order to avoid
these problems, different types of
diesel fuel are distributed according to
the season: summer type, winter type
