then when the service nears, several scenarios are possible:
– distance/time remaining less than 900 miles (1,500 km) or one month: the mes-
sage “Service in” is displayed accompanied by the nearest term (distance or time);
– distance equal to 0 miles or service date reached : the message “Service re-
quired ” is displayed accompanied by the

The vehicle requires a service as soon as possible.

1936 km/2 months
NB: depending on the vehicle, the mileage before service changes according to the driving style (frequent driving at low speed,
door-to-door journeys, extensive use at idle speed, towing a trailer etc). The distance remaining until the next service can there-
fore decrease more quickly in some cases than the actual distance travel\
led.
Resetting the display after the service in accordance with the maintenan\
ce schedule.
The mileage before service must only be reset after a service which complies with the recommendations in the maintenance
schedule.
If you decide to change the oil more frequently, do not reset this data each time the oil is changed to avoid exceeding the re-
placement intervals for other parts in the maintenance schedule.
special note: To reset the distance before service, press and hold one of the display reset buttons for approximately 10 sec-
onds until the display shows the mileage permanently.

Check the condition of the wiper blades. You are responsible for their service life:
– they must remain clean: clean the blades and the windscreen regularly with
soapy water;
– do not use them when the windscreen is dry;
– free them from the windscreen when they have not been used for a long time.
In all cases, replace them as soon as they begin to lose efficiency: approximately
once a year.

In freezing or snowy weather, ensure
they are not stuck to the windscreen
(including the central area located
behind the interior rear-view mirror)
before starting the wipers (risk of
motor overheating).

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 Service Booklet.
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
contact with the hot exhaust system.

Advice: antipollution and fuel economy
aDVICe: antipollution, fuel economy and driving (1/3)
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.aiding fuel economy
Depending on the vehicle, in order to
optimise consumption, an indicator light
on the instrument panel will inform you
of the best moment to upshift or down -
shift gears:
\ shift up a gear;
[ shift down a gear.
Maintenance
It is important to remember that failure to
respect antipollution regulations could
lead to legal action being taken against
the vehicle owner. In addition, replacing
engine, fuel supply system and exhaust
components with parts other than those
originally recommended by the manu -
facturer may alter your vehicle so that
it no longer complies with antipollution
regulations. Have your vehicle adjusted and
checked by an approved 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–
ignition: this does not require ad -
justment.
– spark plugs: for optimum fuel econ-
omy, efficiency 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 approved dealer
for this.
– idle: this does not require adjust -
ment.
– air filter, diesel filter: a clogged ele-
ment reduces performance. It must
be replaced.
