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.

2.8
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.

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.

2.12
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.
Refer to the information on
«Additive tank» in Section 1.

2.13
ENVIRONMENT
Emissions
Your vehicle has been designed to
emit fewer greenhouse gases (CO2)
while in use, and therefore to consume
less fuel (eg. 140 g/km, equivalent to
5.3 l/100 km for a diesel vehicle).
Our vehicles are also equipped with a
particle filter system including a cata-
lytic converter, an oxygen sensor and
an active carbon filter (the latter pre-
vents vapour from the fuel tank being
released into the open air).
For certain diesel vehicles, this system
also has a particle filter to reduce the
volume of soot particles emitted.
Please make your own
contribution towards
protecting the environment
too
– Worn parts replaced in the course of routine vehicle maintenance (vehi-
cle battery, oil filter, air filter, batter-
ies, etc.) and oil containers (empty or
filled with used oil) must be disposed
of through specialist organisations. – At the end of the vehicle’s service
life, it should be sent to approved
centres to ensure that it is recycled.
– In all cases, comply with local legis- lation.
Recycling
Your vehicle is 85% recyclable and
95% recoverable.
To achieve these objectives, many of
the vehicle components have been de-
signed to enable them to be recycled.
The materials and structures have
been carefully designed to allow these
components to be easily removed and
reprocessed by specialist companies.
In order to preserve raw material re-
sources, this vehicle incorporates nu-
merous parts made from recycled plas-
tics or renewable materials (vegetable
or animal-derived materials such as
cotton or wool).
Your vehicle has been designed with
respect for the environment in mind for
its entire service life: during production,
use and at the end of its life.
This commitment is illustrated by the of
the manufacturer eco² signature.Manufacture
Your vehicle has been manufactured at
a factory which complies with a policy
to reduce the environmental impact
on the surrounding areas (reduction of
water and energy consumption, visual
and noise pollution, atmospheric emis-
sions and waste water; sorting and re-
using waste).

Only the temperature and the AUTO
symbol are displayed
Functions managed in automatic mode
are not displayed.
– press button 9 to increase the tem-
perature;
– press button 10 to decrease the tem-
perature.
Note: The maximum and minimum
settings of 15°C and 27°C allow the
system to produce a minimum or maxi-
mum temperature, whatever the ambi-
ent conditions.
In automatic mode (AUTO lit on the
display), all heating and air condi-
tioning functions are controlled by
the system.
When you modify certain functions,
AUTO goes out. Only the modified
function stops being controlled by
the system.
To reach and keep the chosen comfort
level and to maintain good visibility, the
system controls:
– ventilation speed;
– air distribution;
– air recirculation management;
– air conditioning start/stop;
– the air temperature.Automatic mode
Press button 3. AUTO lights up on dis-
play 4.
In most cases, the automatic climate
control system ensures a comfortable
temperature in the passenger compart-
ment, while maintaining good visibility
and optimising fuel consumption.
This is the recommended mode of
use.

Adjusting automatic mode
The system normally operates in auto-
matic mode but you can alter the stand-
ard settings used by the system (air
distribution, etc.). These options are
explained on the following pages.
Automatic mode is the recom-
mended mode of use
In most cases, the automatic cli-
mate control system ensures a com-
fortable temperature in the passen-
ger compartment, while maintaining
good visibility and optimising fuel
consumption.
The types of adjustments that can
be made are described in the follow-
ing pages.
Return to automatic mode as soon
as possible.
The displayed temperature values
show a comfort level.
When starting the engine, increas-
ing or decreasing the value dis-
played will not allow the com-
fort level to be reached any more
quickly. The system will always op-
timise the temperature increase or
decrease (the ventilation system
does not start instantly at maximum
speed: it gradually increases). This
may take several minutes.
Generally speaking, unless there is
a particular reason not to, the dash-
board air vents should remain open.

Operating faults
As a general rule, contact your ap-
proved dealer in the event of an oper-
ating fault.
– Reduction in de-icing, demisting or air conditioning performance.
This may be caused by the passen-
ger compartment filter cartridge be-
coming clogged.
– No cold air is being produced .
Check that the controls are set cor-
rectly and that the fuses are sound.
Otherwise, switch off the system.
Presence of water under the
vehicle
After prolonged use of the air condi-
tioning system, it is normal for water
to be present under the vehicle. This is
caused by condensation.
AIR CONDITIONING: information and operating instructions (1/2)
Do not open the refriger-
ant fluid circuit. The fluid
may damage eyes or skin.
Fuel consumption
You will normally notice an increase in
fuel consumption (especially in town)
when the air conditioning is operating.
For vehicles fitted with air conditioning
with no automatic mode, switch off the
system when it is not required.
Advice for reducing consumption
and helping to preserve the environ-
ment
Drive with the air vents open and the
windows closed.
If the vehicle has been parked in the
sun, open the doors for a few moments
to let the hot air escape before starting
the engine.
Maintenance
Refer to the Maintenance Document
for your vehicle for the inspection fre-
quency.
Advice on use
In some situations (air conditioning off,
air recirculation activated, ventilation
speed at zero or low etc.), you may
notice that condensation starts to form
on the windows and windscreen.
If there is condensation, use the “Clear
View” function to remove it, then use
the air conditioning in automatic mode
to stop it forming again.
Do not add anything to the
vehicle’s ventilation circuit
(for example, to remove
bad odours).
There is a risk of damage or of
fire.
Use the air conditioning system reg-
ularly, even in cold weather, running
it at least once a month for approxi-
mately 5 minutes.
Vehicles equipped with
modeECO
Once activated, ECO mode may
reduce air conditioning perform-
ance. Please refer to the informa-
tion on “Driving advice, Eco-driving”
in Section 2.
