Trip mileage resetting
With “trip mileage recorder” selected on
the display, press button 2 or 3 until the
mileage recorder resets to zero.
Resetting the journey
parameters (reset button)
With one of the journey parameters se-
lected on the display, press button 2
or 3 until the display resets.
Interpreting some of the
values displayed after
resetting
The values showing average fuel con -
sumption, range and average speed
will become more stable and reliable
the further you travel after pressing the
reset button.
For the first few miles after pressing
the reset key you will notice that the
range increases as you travel. This
range takes into account the average
fuel consumption since the last time the
reset button was pressed. Therefore,
the average fuel consumption may de-
crease when:
– the vehicle stops accelerating;
– the engine reaches its operat -
ing temperature (if the engine
was cold when the reset key was
pressed);
– when driving from an urban area
onto the open road.
Automatic resetting of the
journey parameters
Resetting occurs automatically when
the maximum value of any of the pa -
rameters is exceeded.2

fUEL TANK (2/3)
filling with fuel
With the ignition off, insert the nozzle to
open valve B and insert it fully before
turning it on to fill the fuel tank (risk of
splashing).
Keep the nozzle in this position
throughout the entire filling operation.
When the pump cuts out automatically
at the end of the filling procedure, a
maximum of two further filling attempts
may be made, as there must be suffi -
cient space in the fuel tank to allow for
expansion.
Make sure that no water enters the fuel
tank during filling. Valve B and its sur -
round must remain clean.
petrol versions
Using leaded petrol will damage the
antipollution system and may lead to a
loss of warranty.
To ensure that the fuel tank is not filled
with leaded petrol, the fuel tank filler
neck contains a restrictor fitted with a
foolproof system which only allows
the nozzle for unleaded petrol to be
used (at the pump).
v
ehicles running on ethanol -based
fuel
It is essential to use unleaded petrol or
fuel containing a maximum of 85% eth-
anol (E85).
In very cold conditions, it may be very
difficult or even impossible to start the
engine. To avoid this problem, use un-
leaded petrol or, for equipped vehi -
cles, use the heater integrated into the
engine: connect the specified end of
the extension piece supplied into the
socket integrated into the radiator grille
and the other end into a 220v socket
for at least 6 hours before starting.
Note: you may notice an increase in
fuel consumption with this type of fuel.
v ehicle fitted with the Stop and
Start function
To fill up with fuel, the engine must
be stopped (and not on standby):
stop the engine by pressing the
engine stop button 1 (please refer
to the information on “Starting and
Stopping the engine” in Section 2).

stop and start function
StoP aND StaRt function (1/3)
The message “Auto Stop” on the instru-
ment panel indicates that the engine is
on standby.
The vehicle equipment remain opera -
tional while the engine is stopped.
The engine will restart as soon as you
press the clutch pedal and move into
gear.This system enables a reduced fuel
consumption and lower greenhouse
gas emissions.
The system is activated automatically
when the vehicle is started.
While driving, the system stops the
engine (standby) when the vehicle is
at a standstill (traffic jam, traffic lights,
etc).
System operating conditionsEngine standby is activated if:
– the vehicle has been driven since its
last stop;
– the gearbox is in neutral;
– the clutch pedal is released;
and
– the vehicle is travelling at less than 3
km/h. Special feature of the automatic
engine re-start
Under certain conditions, the engine
can restart on its own in order to guar-
antee your safety and comfort.
This can occur especially when:
–
the outdoor temperature is too low or
too high (less than around 0 °C or
higher than around 30 °C);
– the “Clear View” function is activated
(please see “Automatic Climate
Control” in Section 3);
– the battery is not sufficiently charged;
– the vehicle speed is above 7 km/h
(downhill slope, etc.);
– repeated pressing on the brake
pedal or braking system require -
ment;
– ...
Special feature of vehi -
cles equipped with an
electronic parking brake
If the engine is put on
standby (the message “ Auto Stop”
is displayed on the instrument
panel), the electronic parking brake
is not applied automatically.
Engine on standby - braking
assistance is no longer op-
erational.
Before getting out of the
vehicle, you must switch
off the ignition by pressing
the engine stop (please see
“Starting, stopping the engine”).
Do not drive off when the
engine is on standby (the
message “Auto Stop” is dis-
played on the instrument
panel).

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.

advice on use
– Electricity is fuel; switch off all the
electrical components which are
not really needed. however (safety
first), keep your lights on when the
visibility is bad (“see and be seen”).
– Use the air vents. Driving with the
windows open at 60 mph (100 km/h)
will increase fuel consumption by
4%.
– Avoid using the car for door-to-door
calls (short journeys with long waits
in between) because the engine
never reaches its normal operating
temperature.
tyres
– An underinflated tyre increases fuel
consumption.
– The use of non-recommended tyres
can increase fuel consumption.
–
In vehicles fitted with air condi -
tioning, it is normal to observe an
increase in fuel consumption (es -
pecially in urban conditions) when
it is used. For vehicles fitted with
manual air conditioning, switch off
the system when it is not required.
advice for reducing consumption
and therefore helping to preserve
the environment:
If the vehicle has been parked in the
sun, open the doors for a few mo -
ments to let the hot air escape before
starting the engine.
– Never fill the fuel tank right to the
brim to avoid overflow.
– Do not leave an empty roof rack
fitted to the vehicle.
– It is better to fit a trailer for bulky ob-
jects.
– When towing a caravan, fit a wind
deflector and adjust it carefully.
