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.
The following operating conditions
should be avoided:
– driving for long periods when the low
fuel level warning light is lit;
– using leaded petrol;
– using fuel or lubrication additives
which are not approved.
Or operating faults such as:
– faulty ignition system, running out of
fuel or disconnected spark plugs re-
sulting in the engine misfiring or cut-
ting out when driving;
– loss of power;
may cause the catalytic converter to
overheat, reducing its efficiency which
may irreparably damage it and cause
heat damage to the vehicle. If you notice any of the above operating
faults, have the necessary repairs car-
ried out as soon as possible by an ap-
proved dealer.
These faults may be avoided by regu
-
larly taking your vehicle to an approved
Dealer at the intervals specified in the
Maintenance Document.
Starting problems
To avoid damaging the catalytic con -
verter, do not keep trying to start the
engine (using the start button, or by
pushing or towing the vehicle) without
having identified and corrected the
cause of the fault.
If the fault cannot be identified, do not
continue to try and start the engine, but
contact an approved dealer.

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.

Once the operation has been com -
pleted, ensure that the dipstick is
pushed in as far as it will go or that the
cap-type dipstick is completely screwed
in.
enGIne OIL LeVeL: general information (2/2)
Reading the level using the
dipstick
– remove the dipstick (refer to the fol-
lowing pages for its location) and
wipe it with a clean lint-free cloth;
– push the dipstick in as far as it will go
(for vehicles equipped with a “cap -
type dipstick” C , screw the cap in
completely);
– take out the dipstick again;
– read the level: it should never fall
below minimum mark A or exceed
maximum mark B.
Consult your approved Dealer at
once if you notice an abnormal or
repeated drop in any of the fluid
levels.
The engine may be hot
when carrying out opera -
tions in close proximity. In
addition, the engine cooling
fan can come on at any moment.

exceeding the maximum
engine oil level
The oil level should only be read with
the dipstick as explained above.
If the oil level exceeds the maximum
level, do not start your vehicle and
contact an approved Dealer.
Under no circumstances
should maximum filling
level B be exceeded: this
could damage the engine
and the catalytic converter.
Deactivate the Stop and
Start function for any opera -
tion performed in the engine
compartment.
