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.
Please contact an authorised dealer
as soon as possible.
– If there is an assisted parking brake fault, the warning light
® comes
on, along with the message “Braking
system fault”, a beep and, in some
cases, the warning light
}.
This means that you must stop as
soon as traffic conditions allow.
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.
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.
Never leave your vehicle
without moving the selec-
tor lever to position P and
switching off the engine.
This is because when the vehicle is
stationary with the engine running
and a gear engaged, the vehicle
may begin to move.
There is a risk of accidents.If no lights or sounds are ap-
parent, this indicates a fault
in the instrument panel. This
indicates that it is essential
to stop immediately (as soon as traf-
fic conditions allow). Ensure that the
vehicle is correctly immobilised and
contact an approved Dealer.
In the event of message
“Electric failure DANGER”
or “Check battery”, manu-
ally activate the electronic
parking brake by pulling switch 2 (or
position the gear lever in P for au-
tomatic gearboxes) before stopping
the engine.
Risk of loss of immobilisation of the
vehicle.
Contact an authorised dealer.

DRIVING ADVICE, ECO-DRIVING (1/5)
Gear change indicator 2
Depending on the vehicle, to obtain op-
timum consumption levels, a warning
light on the instrument panel lets you
know the best time to move up or down
a gear:
Š move up a gear;
‰ move down a gear.
If you regularly follow this indicator, you
will reduce your vehicle’s fuel consump-
tion.
Fuel consumption is accredited in ac-
cordance with a standard regulatory
method. Identical for all manufactur-
ers, 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 follow-
ing advice.
Depending on the vehicle, you will have
various functions which enable you to
lower your fuel consumption:
– the rev counter with ECO zone;
– gear change indicator;
– the driving style indicator;
– the journey record and eco-driving
advice via the multimedia screen;
– ECO mode.
If fitted on the vehicle, the navigation
system provides additional information.
On the instrument panel A
or B
Depending on the vehicle, the informa-
tion display can be organised and cus-
tomised based on the instrument panel
customisation style selected from the
multimedia screen.
The rev counter with ECO zone 1
Driving in the ECO zone helps you op-
timise fuel consumption under most cir-
cumstances.

DRIVING ADVICE, ECO-DRIVING (3/5)
ECO mode
ECO mode is a function which opti-
mises fuel consumption. It acts upon
certain power consuming systems in
the vehicle (heating, air conditioning,
power-assisted steering, etc.) and on
certain driving actions (acceleration,
gear changing, cruise control, decele-
ration, etc.).
Limiting acceleration enables low fuel
consumption in urban and surrounding
areas. Reduced usage of the air condi-
tioning reduces fuel consumption with-
out affecting heating comfort.
Free wheel in ECO mode
Depending on the vehicle, for vehi-
cles fitted with an automatic gearbox,
switching to “free wheel” is favoured to
slow down the vehicle without using the
engine brake. By releasing the acceler-
ator pedal completely to anticipate de-
celeration, you will save fuel.Activating the function
The function can be activated:
– by pressing switch
6.
– by pressing the switch 7 (please refer
to the information on “Multi-Sense” in
Section 3);
– from the navigation menu on the multimedia screen (please refer to
the multimedia instructions).
The 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.
For this, depress the accelerator pedal
firmly and fully.
ECO mode is reactivated when you
take pressure off the accelerator pedal.
Disabling the function
Press switch 6.
The warning light
 goes out on
the instrument panel to confirm deac-
tivation.
The distance covered in “free wheel”
mode is displayed, depending on the
vehicle, on the multifunction screen 4
or the instrument panel 5.
To activate/deactivate the “free wheel”
mode, see “Vehicle settings customisa-
tion menu” in Section 1.

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 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 fail-
ure 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 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
– 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
authorised dealer for this.
– Air filter, fuel 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 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.

TYRE PRESSURE MONITORING SYSTEM (2/3)
Display
The display 1 and the warning light 4
 on the instrument panel warn
you of any tyre pressure faults (flat tyre,
punctured tyre, system fault, etc.).
“Puncture”
A wheel B is shown, depending on the
vehicle, in red or white accompanied
by the warning light 4
 fixed, the
message “Puncture” and a beep.
This message appears along with the
® warning light. They indicate that
the affected wheel is punctured or se-
verely underinflated. Replace it or con-
tact an approved dealer if it is punc-
tured. Top up the tyre pressure if the
wheel is deflated.
“Check tyre pressure sensors”
A wheel A disappears, the warning
light 4
 flashes for several sec-
onds then comes on continuously and
the message “Check tyre pressure sen-
sors” appears.
This message appears along with the
© warning light. They indicate that
at least one wheel is not fitted with sen-
sors (e.g. emergency spare wheel).
Otherwise, consult an authorised
dealer.
“Adjust tyre pressure”
A wheel B is shown, depending on the
vehicle, in orange or white accompa-
nied by the warning light
4
 fixed
and the message “Adjust tyre pres-
sure”. They indicate that a wheel is de-
flated.
Check and, if necessary, readjust the
pressures of the four wheels when cold.
The warning light 4
 goes off after
a few minutes’ driving.

Operating faults:
–
© and x lit up on the in-
strument panel alongside mes-
sages “Check ABS”, “Check braking
system” and “Check ESC”: indicates
the ABS, ESC and emergency brake
assist are deactivated. Braking is
always enabled;
–
x, D, © and ® lit
up on the instrument panel alongside
the message “Braking system fault”:
this indicates a fault in the braking
system.
In both cases, consult an approved
dealer.
Your braking systems
are partially operational.
However, it is dangerous
to brake suddenly and
it is essential to stop immediately,
as soon as traffic conditions allow.
Contact an approved dealer.Warning light ® re-
quires you to stop immedi-
ately, for your own safety,
as soon as traffic conditions
allow. Switch off the engine and do
not restart it. Contact an approved
Dealer.

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
© and  appear
on the instrument panel.
In this case, the ESC and traction con-
trol system are deactivated. Consult an
authorised dealer.

DRIVER CORRECTION DEVICES AND AIDS (4/10)
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. 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.
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.

2.34
DRIVER CORRECTION DEVICES AND AIDS (5/10)
If the driver depresses the brake pedal
and the system still detects a risk of col-
lision, the brake force is increased.
If the driver fails to react following
an alert of an imminent collision, the
system activates the brakes.
Active emergency braking
Using the sensor 1, the system calcu-
lates the distance separating the vehi-
cle from the one in front and alerts the
driver if there is a risk of a front-end col-
lision. The driver can then brake the ve-
hicle to limit the damage arising from a
collision.
Note: Make sure that the sensor 1 is
not obscured (by dirt, mud, snow, etc.).
Operation
When driving (speed between 18.6 and
93 mph (30 and 150 km/h), if there is a
risk of collision with the vehicle in front,
depending on the vehicle:
– the warning light
 is displayed
in red on the instrument panel, ac-
companied by a beep;
or
– the indicator 2 is displayed in red on
the instrument panel and, depending
on the vehicle, on the head up dis- play, accompanied by a beep.
The system only detects vehicles
driving in the same direction of traf-
fic. The system cannot detect mo-
torcycles because of the difficulty in
forecasting their trajectory.
