SPECIAL FEATURES OF DIESEL VERSIONS
Diesel engine speed
Diesel engines are fitted with injection
equipment which prevents the engine
speed being exceeded irrespective of
the gear selected.
If the message “CHECK ANTI-
POLLUTION SYSTEM” is displayed
along with warning 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 drai-
ned, the system must be reprimed after
the tank is refilled: see information on
the “fuel tank” in section 1 before res-
tarting the engine.
Do not park the vehicle or
run the engine in locations
where combustible subs-
tances 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 re- latively full to avoid water vapour
condensing in it and accumulating at
the bottom of the tank.

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. 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.

ECO mode
ECO mode is a function which opti-
mises fuel consumption. It acts on all
elements which consume fuel (engine
power, heating and/or air conditioning,
etc).Disabling the function
Press switch 4.
The 5
 light goes out on the instru-
ment panel to confirm deactivation.
Activating the function
Press switch 4.
The
5  warning light comes on on
the instrument panel to confirm activa-
tion.
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.

2.16
Driving advice, Eco-driving
Behaviour
– Drive carefully for the first few miles until the engine reaches its normal
operating temperature, rather than
let it warm up while the vehicle is sta-
tionary.
– Speed is expensive.
– Sporty driving uses a lot of fuel: drive with a light right foot.
– Do not overrev the engine in the in- termediate gears.
You should always use the highest gear possible.
Obstructions to the driver
On the driver’s side, only
use mats adapted to the ve-
hicle that attach to the pre-
installed parts, and regularly check
their mounting. Do not place several
mats on top of each other.
There is a risk of wedging the
pedals
DRIVING ADVICE, ECO-DRIVING (4/5)
– Avoid sudden acceleration.
– Brake as little as possible. If you an- ticipate an obstacle or bend in ad-
vance, you may then simply release
the accelerator pedal.
– Do not try to maintain the same speed up a hill, accelerate no more
than you would on the level. Keep
your foot in the same position on the
accelerator pedal.
– Double declutching and accelerating before switching off are unnecessary
in modern vehicles.
– Bad weather, flooded roads:
Do not drive through
floods if the water is
above the lower edge of
the wheel rims.

2.17
DRIVING ADVICE, ECO-DRIVING (5/5)
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 (espe-
cially 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.
– It is better to fit a trailer for bulky ob- jects.
– When towing a caravan, fit a wind deflector and adjust it carefully.
– 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.

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 repro-
cessed by recycling companies.
By virtue of its design, moderate fuel
consumption and initial settings, your
vehicle also conforms to current anti-
pollution regulations. The manufactu-
rer is actively striving to reduce pollu-
tant 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 maintai-
ned and used correctly.
Maintenance
It is important to remember that fai-
lure 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 manufactu-
rer may alter your vehicle so that it no
longer complies with antipollution regu-
lations.
Have your vehicle adjusted and chec-
ked by an approved Dealer, in accor-
dance 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
approved dealer for this.
– Air filter, diesel 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 subs-
tances may be released into the atmos-
phere or damage may occur.
ÄThis warning light on the ins-
trument 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 pos-
sible;
– if it flashes, reduce the engine speed until the light stops flashing. Contact
your approved dealer as soon as
possible.

2.24
Electronic stability program
(ESC) with understeer control
and traction control
Electronic stability control ESC
This system helps you to keep control
of the vehicle in critical driving condi-
tions (avoiding an obstacle, loss of grip
on a bend, etc.).
Operating principle
A sensor in the steering wheel detects
the direction selected by the driver.
Other sensors throughout the vehicle
measure the actual direction.
The system compares driver input to
the actual trajectory of the vehicle and
corrects the trajectory if necessary by
controlling the braking of certain wheels
and/or engine power. In the event that
the system is engaged, indicator light
 flashes on the instrument panel.
DRIVER CORRECTION DEVICES AND AIDS (2/4)
Understeer control
This system optimises the action of the
ESC in the case of pronounced under-
steer (loss of front axle road holding).
Traction control
This system helps to limit wheelspin of
the drive wheels and to control the ve-
hicle when pulling away accelerating or
decelerating.
Operating principle
Using the wheel sensors, the system
measures and compares the speed of
the drive wheels at all times and slows
down their over-rotation. If a wheel is
starting to slip, the system brakes au-
tomatically until the drive supplied be-
comes compatible with the level of grip
under the wheel again.
The system also adjusts the engine
speed to the grip available under the
wheels, independently of the pressure
exerted on the accelerator pedal.Operating faults
When the system detects an operating
fault the message “CHECK ESC” and
warning light
© and  appear
on the instrument panel. In this case,
the ESC and traction control system
are deactivated.
Consult an approved dealer.
Disabling the traction control
system
In some situations (driving on very wet
ground: snow, mud, etc. or driving with
snow chains fitted), the system may
reduce the engine output to limit whee-
lspin.

2.39
AUTOMATIC TRANSMISSION (2/3)
Driving in manual modeWith the selector lever in position D,
move the lever to the left into the M po-
sition. Shifting the lever or the paddles
repeatedly allows you to change gears
manually:
– to move down through the gears, push the lever forwards or press the
left-hand paddle;
– to move up through the gears, push the lever backwards or press the
right-hand paddle.
The gear selected is displayed on the
instrument panel.
Special casesIn certain driving conditions (for exam-
ple, engine protection, operation of the
Electronic Stability Programme: the au-
tomatic system may change gear auto-
matically. Likewise, to prevent incorrect
manoeuvres, a gear change may be re-
fused by the automatic system: in this
case the gear display flashes for a few
seconds as a warning.
Special circumstances
– If the bends and road surface do
not allow you to stay in automatic
mode (e.g. in the mountains), we
recommend that you change to
manual mode. This will prevent the
automatic gearbox from changing
gear repeatedly when climbing, and
permit engine braking on long de-
scents.
Driving in automatic mode
Put lever 1 into position D.
In most road conditions you will en-
counter, you will not need to touch your
lever again: the gears will change au-
tomatically at the right time and at the
most suitable engine speed because
the automatic system takes into ac-
count the vehicle load and road contour
and adjusts itself to the particular driv-
ing style you have chosen.
Economical driving
When driving, always leave the lever
in position D, keeping the accelerator
pedal lightly depressed to ensure auto-
matic gear changes at a lower engine
speed.
Accelerating and overtaking
Depress the accelerator pedal firmly
and fully (so that it goes beyond the
kickdown point).
This will enable you to change down
to the optimum gear within the
engine range.
When facing uphill, to remain
stopped, do not keep your foot on
the accelerator.
Risk of overheating the automatic
gearbox.

3.6
Adjusting the ventilation
speed
Move control 2. The further the control is positioned to the right, the greater the
amount of air blown into the passenger
compartment. If you want to shut off the
flow of air, set control 2 to OFF.

MANUAL AIR CONDITIONING (3/3)
The system is deactivated: the ventila-
tion speed is zero (vehicle stationary).
You can, however, still feel a slight flow
of air when the vehicle is moving.
Rapid demisting
Turn controls 1, 2 and 4 to positions
W:
– air from the outside;
– maximum temperature;
– demisting.
1234
65
Positions W and i prevent air recirculation mode to avoid any risk of
condensation forming on the windscreen and triggers the air conditioning\
func-
tion. The integrated light in button 3 does not come on.
Adjusting the air temperature
Turn control 1 to obtain the desired
temperature. The further towards the
red the slide is, the higher the tempera-
ture will be.
When the air conditioning system is
used for long periods, it may begin to
feel cold. To increase the temperature,
turn control 1 to the right.
Rear screen de-icing/
demisting
With the engine running, press
button 5. The operating tell-tale comes
on.
This function permits rapid demisting/
de-icing of the rear screen and de-icing
of the door mirrors (on equipped vehi-
cles).
To exit this function, press button 5
again.
Demisting automatically stops.

3.11
AIR CONDITIONING: information and advice on use
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.
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.
Advice on use
In some situations, (air conditioning
off, air recirculation activated, ventila-
tion 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.
