Diesel engine speed
Diesel engines are fitted with injection
equipment which prevents the engine
speed being exceeded irrespective of
the gear selected.
If the message “Check antipollu -
tion” is displayed on the instrument
panel accompanied by the
Ä and
©warning light; consult an ap -
proved dealer straight away.
When driving, depending on the fuel
grade used, it is possible that white
smoke may be emitted.
This is due to the exhaust particle filter
being cleaned automatically, and does
not affect the way the vehicle runs.
Running out of fuel
If the tank has been completely
drained, the system must be reprimed
after the tank is refilled: see information
on the “fuel tank” in section 1 before re-
starting the engine.
Do not park the vehicle or
run the engine in locations
where combustible sub -
stances or materials such
as grass or leaves can come into
contact with the hot exhaust system.
Precautions to be taken in
winter
To avoid any faults in icy weather:
– ensure that the battery is always fully
charged,
– always keep the diesel tank rela -
tively full to avoid water vapour con-
densing in it and accumulating at the
bottom of the tank.
