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 warn-
ing 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
drained, the system must be reprimed
after the tank is refilled: see information
on the “fuel tank” in section 1 before re-
starting the engine.
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.
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 rela- tively full to avoid water vapour con-
densing in it and accumulating at the
bottom of the tank.

2.12
Before leaving the vehicle,
check that the electronic
parking brake is fully ap-
plied. Indicator light 2 on
switch 3 and indicator light
}
on the instrument panel light up to
show that the parking brake is ap-
plied but go out when the doors are
locked.
Note:
To indicate that the electronic parking
brake is released, a beep sounds and
the message “Apply parking brake” ap-
pears on the instrument panel:
– with the engine running: when the driver’s door is opened;
– with the engine switched off (eg. when the engine stalls): when a front
door is opened.
In this case, pull and release switch 3 to
apply the electronic parking brake.
Automatic releasing of the
electronic parking brake
The brake will be released as soon as
the vehicle moves, by accelerating with
a gear selected and the engine running.
Automatic operation
The electronic parking brake en-
sures vehicle immobilisation when the
engine is stopped and engine Start/
Stop button 1 is pressed.
In all other instances, e.g. engine stal-
ling, the electronic parking brake is not
applied automatically. Manual mode
must be used.
For certain country-specific model ver-
sions, the automatic brake application
function is not activated. Refer to the in-
formation on “Manual operation”.
ELECTRONIC PARKING BRAKE (1/3)
To confirm that the electronic parking
brake is applied, the message “Parking
brake on” and warning light
}
on the instrument panel and warning
light 2 on the switch 3 light up.
After the engine is switched off, indi-
cator light 2 goes out several minutes
after the electronic parking brake has
been applied and indicator light
}
goes out when the vehicle is locked.

2.14
– If there is an electronic parking brake fault, warning lights
® light up
accompanied by the “Parking brake
fault” message, a beep and, in cer-
tain cases, warning light
}.
This means that you must stop as
soon as traffic conditions allow.
Operating faults
– If there is a fault, the © warning
light illuminates on the instrument
panel accompanied by the “Check
parking brake” message and, in
some cases, the
} warning
light.
Contact an approved Dealer as soon
as possible.
ELECTRONIC PARKING BRAKE (3/3)
It is therefore essential to
immobilise the vehicle by
engaging first gear (manual
gearbox) or position P (au-
tomatic gearbox). If the slope re-
quires it, chock the vehicle.
Versions with an automatic
gearbox
For safety reasons, automatic release
is deactivated when the driver’s door
is open or not shut properly and the
engine is running (in order to prevent
the vehicle from moving without the
driver). The “Release parking brake
manually” message appears on the
instrument panel when the driver de-
presses the accelerator.
Never leave your vehicle
without moving the selec-
tor lever to position P or N.
This is because when the
vehicle is stationary with the engine
running and a gear engaged, the
vehicle may begin to move if you
accelerate.
There is a risk of accidents.If no lights or sounds are
apparent, this indicates
a fault in the instrument
panel. This indicates that
it is essential to stop immediately
(as soon as traffic conditions allow).
Ensure that the vehicle is correctly
immobilised and contact an appro-
ved Dealer.

DRIVING ADVICE, ECO-DRIVING (2/3)
An overall rating from 0 to 100 is dis-
played to let you assess your eco driv-
ing performance. The higher the score,
the better your eco-driving perform-
ance.
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.
Obstructions to the driver
On the driver’s side, only
use mats suitable for the
vehicle, attached with the
pre-fitted components, and check
the fitting regularly. Do not lay one
mat on top of another.
There is a risk of wedging the
pedals
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. – 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.

2.18
MAINTENANCE AND ANTI-POLLUTION 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 of the parts on your vehicle have
been designed to be recycled later.
These parts are easily removable in
order to be collected and reprocessed
in recycling networks.
Furthermore, by virtue of its design,
moderate fuel consumption and initial
settings, your vehicle also conforms
to current anti-pollution regulations.
The manufacturer is actively striving
to reduce pollutant exhaust gas emis-
sions and to save energy. However,
the fuel consumption of your vehicle
and the level of pollutant exhaust gas
emissions are also your responsibility.
Ensure that it is maintained and used
correctly.Maintenance
It is important to remember that fail-
ure to respect anti-pollution 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 manufac-
turer may alter your vehicle so that it
no longer complies with anti-pollution
regulations.
Have your vehicle adjusted and
checked by an authorised 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, fuel filter: a choked ele-
ment will reduce efficiency. It must
be replaced.
– Idle speed: no adjustment 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 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
an authorised dealer as soon as pos-
sible.

DRIVER CORRECTION DEVICES AND AIDS (2/4)
Electronic stability control
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.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 operat-
ing fault the message “Check ESC” and
warning light
© appear on the in-
strument panel.
In this case, the ESC and traction
control system are deactivated. Consult
an authorised dealer.

2.26
The traction control system offers ad-
ditional safety. It is recommended that
you do not drive with the function di-
sabled. Correct this as soon as pos-
sible by pressing the switch 1 again.
Note: the function is reactivated auto-
matically when the ignition is switched
on or when a speed of approximately
24 mph (40 km/h) is exceeded.
Emergency brake assist
This system supplements the ABS
and helps reduce vehicle stopping dis-
tances.
Operating principle
The system is for detecting an emer-
gency braking situation. In this case,
the braking assistance immediately de-
velops maximum power and may trig-
ger ABS regulation.
ABS braking is maintained as long as
the brake pedal is applied.
Hazard warning lights switching on
Depending on the vehicle, these may
light up in the event of sudden decel-
eration.
Operating faults
When the system detects an operat-
ing fault the message “Check brak-
ing system” appears on the instrument
panel along with the
© warning
light.
Consult an approved dealer.
Braking anticipation
Depending on the vehicle, when you
rapidly release the accelerator, the
system anticipates the braking ma-
noeuvre in order to reduce stopping
distances.
Special cases
When using the cruise control:
– if you use the accelerator, when you release it, the system may be trig-
gered;
– if you do not use the accelerator, the system will not be triggered.
DRIVER CORRECTION DEVICES AND AIDS (3/4)
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 wheel-
spin. If this is not required, it is possible
to deactivate the function by pressing
switch 1.
The message “Traction control off” is
displayed on the instrument panel to
inform you.
