SPECIAL FEATURES OF PETROL VERSIONS
The following operating conditions:
– 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,
as they may cause the catalytic con-
verter to overheat and thus reduce its
efficiency, or damage it irreparably
and cause heat damage to the vehi-
cle. 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
starting fault.
If the fault cannot be identified, do not
keep trying to start the engine, but con-
tact an approved Dealer.
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 con-
tact with the hot exhaust system.

2.15
SPECIAL FEATURES OF DIESEL VERSIONS
Diesel engine speed
Diesel engines are fitted with an injec-
tion pump which prevents the engine
speed being exceeded irrespective of
the gear selected.
If the message “Check antipollution
system” is displayed along with warn-
ing lights
Ä and ©, consult an
authorised dealer immediately.
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.

MAINTENANCE AND ANTIPOLLUTION ADVICE
Your vehicle complies with criteria for
recycling and recovering vehicles at the
end of their service life which will come
into force in 2015.
Some parts of your vehicle have there-
fore been designed to facilitate future
recycling.
These parts are easy to remove so
that they can be recovered and reproc-
essed by recycling companies.
By virtue of its design, moderate fuel
consumption and initial settings, your
vehicle also conforms to current anti-
pollution regulations. The manufac-
turer is actively striving to reduce pol-
lutant exhaust gas emissions and to
save energy. But the fuel consumption
of your vehicle and the level of pollutant
exhaust gas emissions are also your
responsibility. Ensure that it is main-
tained and used correctly.
Maintenance
It is important to remember that fail-
ure to respect antipollution regulations
could lead to legal action being taken
against the vehicle owner.In addition, replacing engine, fuel
supply system and exhaust compo-
nents with parts other than those origi-
nally recommended by the manufac-
turer may alter your vehicle so that it
no longer complies with anti-pollution
regulations.
Have your vehicle adjusted and
checked by an authorised dealer, in ac-
cordance with the instructions given in
your maintenance schedule: they will
have all the equipment necessary for
ensuring that your vehicle is maintained
to its original standard.
Engine adjustments
– Spark plugs:
for optimum condi-
tions of use, output and performance
the specifications laid down by our
Design Department must be strictly
applied.
If the spark plugs have to be changed, use the make, type and gap specified
for your vehicle’s engine. Contact an
authorised dealer for this.
– Air filter, fuel filter: a choked ele-
ment will reduce efficiency. It must
be replaced.
– Ignition and idle speed: no adjust-
ment is needed.
Exhaust gas monitoring
system
The exhaust gas monitoring system will
detect any operating faults in the vehi-
cle’s antipollution system.
If this system malfunctions, toxic sub-
stances may be released into the at-
mosphere or damage may occur.
ÄThis warning light on the in-
strument panel will indicate if
there are any faults in the system:
This lights up when the ignition is
switched on and goes out when the
engine is started.
– If it lights up continuously, consult an approved Dealer as soon as possi-
ble;
– if it flashes, reduce the engine speed until the light stops flashing. Contact
an authorised dealer as soon as pos-
sible.

4.7
Engine oil grade
Refer to the Maintenance Service
Booklet for your vehicle.
Never run the engine in an
enclosed space as exhaust
gases are poisonous.
Engine oil change: if you
are changing the oil when
the engine is hot, be careful
not to scald yourself if the
oil overflows.
Filling: take care when
topping up the oil that
no oil drips onto engine
components - risk of fire.
Remember to refit the cap securely
as there is a risk of fire if oil splashes
onto hot engine components.
Consult your approved Dealer at
once if you notice an abnormal or
repeated drop in any of the fluid
levels.
ENGINE OIL LEVEL: topping up, filling (3/3)/OIL CHANGE
Exceeding the maximum
engine oil level
Under no circumstances
must the maximum fill level
be exceeded: risk of damage to the
engine and catalytic converter.
If the oil level exceeds the maximum
level, do not start your vehicle and
contact an approved Dealer.
Oil change
Service interval: refer to the
Maintenance Service Booklet for your
vehicle.
Oil change capacity
Please refer to the maintenance docu-
ment for your vehicle, or contact an au-
thorised dealer.
Always check the engine oil level using
the dipstick, as explained previously (it
should never fall below the minimum
level, or be over the maximum level on
the dipstick).
When working in the engine
compartment, ensure that
the windscreen wiper stalk
is in the park position.
Risk of injury.
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.
Risk of injury.

OPERATING FAULTS (4/7)
On the roadPOSSIBLE CAUSESWHAT TO DO
Vibrations. Tyres not inflated to correct pres-
sures, incorrectly balanced or dam-
aged. Check the tyre pressures: if this is not the
problem, have them checked by an ap-
proved Dealer.
White smoke from the exhaust. In the diesel version, this is necessar-
ily a fault. Smoke may be caused by
particle filter regeneration. Refer to the information on “Special fea-
tures of diesel versions” in Section 2.
Smoke under the bonnet. Short-circuit or cooling system leak. Stop, switch off the ignition, stand away
from the vehicle and contact an approved
dealer.
The oil pressure warning light comes
on: while cornering or braking The level is too low. Top up the engine oil level (refer to the in-
formation on “Engine oil level: topping up,
filling” in Section 4).
