ADDITIVE TANK (2/6)Precautions for use
Always read the information on the ad-
ditive can.
Handle additives with care. They can
damage clothes, shoes, bodywork
components etc.
If the additive overflows, or contami-
nates any paintwork, clean the affected
area quickly with a damp cloth.
In extreme cold weather conditions
The vehicle is fitted with a system for
reheating the additive fluid that enables
you to drive in extreme cold weather
conditions.
Precautions when filling the tank
The additive fluid freezes below about
-10°C.
In this case, do not attempt filling when
the fluid is frozen.
It is therefore advisable to top up the
additive fluid or have it topped up by a
qualified professional as soon as the
 warning light on the instrument
panel first comes on.
The additive must not come
into contact with eyes or
skin. If it does, wash the af-
fected area with plenty of
cold water. If necessary, consult a
doctor.
Additive quality
Use only additives which conform
to standard ISO 22241 and in accor-
dance with the label on the fuel filler
flap.
Average fuel consumption
Approximately 810 mpg
(3.5 L/1,000 km) depending on the ve-
hicle and the driving style.

2.4
For manual gearboxes:
– the gearbox is in neutral;
and
– the clutch pedal is released.
If warning light
 flashes, this
means that the clutch pedal is not suf-
ficiently released.
and
– the vehicle speed is less than ap- proximately 2 mph (3 km/h).
The engine will restart when you press
the clutch pedal and move into gear.
For all vehicles:
Warning light
 on the instru-
ment panel is lit when the engine is on
standby.
The vehicle equipment remain opera-
tional while the engine is stopped.
STOP AND START FUNCTION (1/3)
Do not drive off when the
engine is on standby (warn-
ing light
 is displayed
on the instrument panel).
If you get out of the vehicle, a beep
notifies you that the engine is on
standby and has not been switched
off.
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).
Conditions for engine
standby
The vehicle has set off from where it
was parked;
For sequential gearbox:
– the gearbox is in position A, Mor N;
and
– the brake pedal is depressed (suffi- ciently hard);
and
– the accelerator pedal is not de- pressed;
and
– the speed is zero for around 1 second.
The engine remains on standby if posi-
tion P is selected, or if position N is se-
lected with the handbrake engaged and
the brake pedal released.
If the engine stalls while the system
is in operation, pressing the clutch
pedal right down will start it again.
Before leaving the vehicle,
the engine must be stopped
and not put on standby
(please see the information
on “Starting, stopping the engine” in
Section 2).

2.5
Preventing the engine from
standing by
In certain situations, such as negotiat-
ing a crossroads for instance, it is pos-
sible (with the system activated) to keep
the engine running so as to be ready to
move off quickly.
SEQUENTIAL gearbox
Keep the vehicle stationary without
pressing too hard on the brake pedal.
Manual gearbox
Keep the clutch pedal pressed right
down.
STOP AND START FUNCTION (2/3)Conditions for coming out of
engine standby
For sequential gearbox:
– the brake pedal is released, position A or M engaged, or;
– the brake pedal is released, position N engaged and the handbrake off,
or;
– or the brake pedal is pressed again, with position P engaged or position
N engaged with the parking brake
applied or;
– position R is engaged or;
– the accelerator pedal is pressed.
For manual gearboxes:
– the gearbox is in neutral and the clutch pedal is slightly depressed, or
– the engine is in gear and the clutch pedal is pressed right down.
Conditions preventing the
standby of the engine
Certain conditions prevent the system
from using the engine standby function,
including when:
– reverse gear is engaged;
– the bonnet is not locked; – the outdoor temperature is too low or
too high (less than around 0 °C or
higher than around 35 °C);
– the battery is not sufficiently charged;
– the difference between the vehicle interior temperature and the auto-
matic climate control instruction is
too high;
– the “Clear View” function is activated (please see “Automatic Climate
Control” in Section 3);
– the engine coolant temperature is too low;
– automatic particle filter cleaning is underway;
– the “Fast Idle Speed” function is acti- vated (please refer to the information
on “Fast Idle Speed” in section 2);
– ...
Warning light
 is displayed on the
instrument panel. This notifies you that
the engine is on standby.
To fill up with fuel, the engine must
be stopped (and not on standby):
stop the engine (Please See
“Starting, stopping the engine” in
Section 2).

2.7
SPECIAL FEATURES OF DIESEL VERSIONS
Precautions to be taken in
winter
To avoid any faults in icy weather:
– make sure that the battery is always fully charged;
– always keep the diesel tank rela- tively full to prevent water vapour
condensing in it and accumulating at
the bottom of the tank.
Diesel engine speed
Diesel engines are fitted with an injec-
tion pump with an electronic regulator
which prevents overrevving of the
engine irrespective of the gear en-
gaged.
If the
Ä and © warning lights
come on, consult an approved dealer
as soon as possible.
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
You may start the engine normally after
refilling the fuel tank even if you have
completely run out of fuel, provided
that the battery is fully charged.
However, if the engine does not start
after a few seconds and several at-
tempts, refer to the information on the
“Fuel tank” in Section 1.
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.

DRIVING ADVICE, ECO-DRIVING (1/4)
Fuel consumption is accredited in ac-
cordance with a standard regulatory
method. Identical for all manufactu-
rers, this enables vehicles to be com-
pared with one another. Consumption
in real time depends on vehicle usage
conditions, the equipment fitted and the
user’s driving style. To optimise fuel
consumption, please refer to the fol-
lowing advice.
Depending on the vehicle, you will have
various functions which enable you to
lower your fuel consumption:
– the rev counter;
– gear change indicator;
– the journey record and eco-driving advice via the multimedia display;
– ECO mode – activated by the ECO button.
If fitted on the vehicle, the navigation
system provides additional information.
Gear change indicator 1
and 2
(depending on vehicle)
To obtain optimum consumption levels,
a warning light on the instrument panel
lets you know the best time to move
up a gear, or down a gear for vehicles
where this is fitted:
Š move up a gear;
‰ move down a gear.

DRIVING ADVICE, ECO-DRIVING (2/4)ECO mode
ECO mode is a function which op-
timises fuel consumption. It acts on
certain power consuming systems in
the vehicle (heating, air conditioning,
power-assisted steering, etc.) and on
certain driving actions (acceleration,
gear changing, cruise control, deceler-
ation, etc.).
Activating the function
Press switch 4.
The warning light in the 4 switch lights
up.
While driving, it is possible to leave the
ECO mode temporarily in order to im-
prove engine performance.
Depress the accelerator pedal firmly
and fully.
ECO mode is reactivated when you
take pressure off the accelerator pedal.
Disabling the function
Press switch 4.
The indicator light in the switch 4 goes
out.

An overall rating from 0 to 100 is dis-
played to let you assess your eco driv-
ing performance. The higher the rating,
the lower the fuel consumption.
Eco advice is given to help improve
your performance.
With your favourite journeys saved, you
can evaluate your performance.
For more information, please see the
multimedia system instructions.Journey record
Once the engine is switched off, you
will see “Journey record” displayed on
the screen 3, enabling you to view in-
formation relating to your last journey.
This indicates:
– average fuel consumption;
– number of miles/kilometres travelled;
– number of miles/kilometres saved.

2.11
DRIVING ADVICE, ECO-DRIVING (4/4)
Advice on use
– Favour ECO mode.
– 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%.
– Never fill the fuel tank right to the brim to avoid overflow.
– 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.
– Do not leave an empty roof rack fitted to the vehicle.
– When towing a caravan, fit a wind deflector and adjust it carefully.
Tyres
– An underinflated tyre increases fuel consumption.
– The use of non-recommended tyres can increase fuel consumption.

MAINTENANCE AND ANTIPOLLUTION ADVICE
Your vehicle complies with criteria for
recycling and recovering vehicles at the
end of their service life, which entered
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 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
– Air filter, diesel filter: a choked el-
ement will reduce efficiency. It must
be replaced.
– Idle speed: this does not require ad- justment.
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
your approved dealer as soon as
possible.
