ELECTRONIC PARKING BRAKE (2/3)Special cases
To park on a slope or while towing a
trailer, for example, pull switch 2 for
a few seconds to gain the maximum
braking.
To park the vehicle without applying the
electronic parking brake (if there is a
risk of freezing, for example):
– with the engine running, while simul- taneously keeping the brake pedal
and switch 2 depressed, switch off
the engine by pressing the engine
Start/Stop button 1;
– in gear, release the brake pedal and switch 2.
For vehicles fitted with the Stop and
Start function, with the engine on
standby, the electronic parking brake is
automatically activated if the driver un-
fastens their seat belt or opens the driv-
er's door or gets out of their seat.
Brief stop
To manually activate the electronic
parking brake, (when stopping at a red
light, or stopping when the engine is
running, etc.): pull and release switch 2.
The brake is released as soon as the
vehicle is started up again.
Manual operationYou can control the electronic parking
brake manually.
Applying the electronic parking
brake
Pull switch 2. Warning light 3 and warn-
ing light
} on the instrument panel
light up.
Releasing the electronic parking
brake
With the ignition on, depress the brake
pedal then press switch 2: warning
light 3 and warning light
} go out.

Special feature related to the Stop and Start function: if the driver's \
seat
is unfastened before the engine goes into standby due to the Stop and
Start function, make sure that the parking brake is applied: the
} in-
dicator light on the instrument panel confirms this. Risk of loss of immobilisa-
tion.

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.
If the message “Electric fail-
ure DANGER” or “Check
battery” appears, manually
activate the electronic park-
ing brake by pulling switch 2 (or po-
sition the gear lever in P for auto-
matic gearboxes) before stopping
the engine.
Risk of loss of immobilisation of the
vehicle.
Contact an authorised dealer.

Driving advice and 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.
– Dynamic driving with a lot of frequent acceleration and braking is expen-
sive on fuel in comparison to the time
saved.
– 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 flat ground. Keep
your foot in the same position on the
accelerator pedal.
– Double declutching and accelerating before switching off are unnecessary
in modern vehicles.
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 (4/5)
– Bad weather, flooded roads:
Do not drive through
floods if the water is
above the lower edge of
the wheel rims.

2.30
DRIVER CORRECTION DEVICES AND AIDS (1/10)ABS (anti-lock braking
system)
Under heavy braking, the ABS prevents
the wheels from locking, allowing the
stopping distance to be managed and
keeping control of the vehicle.
Under these circumstances, the vehi-
cle can be steered to avoid an obstacle
whilst braking. In addition, this system
can increase stopping distances, par-
ticularly on roads with low surface grip
(wet ground etc.).
You will feel a pulsation through the
brake pedal each time the system is
activated. The ABS does not in any way
improve the vehicle's physical perform-
ance relating to the road surface and
roadholding. It is still essential to follow
the rules of good driving practice (such
as driving at a safe distance from the
vehicle in front etc.).
– ABS (anti-lock braking system);
– ESC
(electronic stability control)
with understeer control and trac-
tion control;
– emergency brake assist;
– active emergency braking;
– hill start assistance;
– rear wheel steering.
Other driving assistance systems are
detailed on the following pages.
In an emergency, apply firm and
continuous pressure to the brake
pedal. There is no need to pump
it repeatedly. The ABS will modu-
late the force applied in the braking
system.
These functions are an ad-
ditional aid in the event of
critical driving conditions,
enabling the vehicle behav-
iour to be adapted to suit the driving
conditions.
The functions do not take the place
of the driver. They do not increase
the vehicle’s limits and should
not encourage you to drive more
quickly. Therefore, they can under
no circumstances replace the vigi-
lance or responsibility of the driver
when manoeuvring the vehicle (the
driver must always be ready for
sudden incidents which may occur
when driving).

Operating faults:
–
© and x lit up on the in-
strument panel accompanied by the
messages “Check ABS”, “Check
braking system” and “Check ESC”:
this indicates that the ABS, the ESC
and the emergency brake assist are
disabled. Braking is always ena-
bled;
–
x, D, © and ®
lit on the instrument panel accom-
panied by the message “Braking
system fault”: this indicates a fault
with 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 19 and
87 mph (30 and 140 km/h) or depend-
ing on the vehicle, 93 mph (150 km/h)),
if there is a risk of collision with the ve-
hicle in front, depending on the vehicle:
– the warning light
\b 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.

Active emergency braking
Limitation of the system operation
– The system will only respond to vehicles which are moving or which have \
been sensed as moving.
– A vehicle travelling in the opposite direction will not trigger any alert\
or any action on the system operation.
– The sensor area should be kept clean and free of any modifications in or\
der to ensure the proper operation of the system.
– The system cannot respond to small vehicles such as motorbikes or bicycl\
es as effectively as to other vehicles.
Deactivating the function
You must disable the function if:
– the brake lights are not functioning;
– the front of the vehicle has undergone an impact or been damaged;
– the vehicle is being towed (breakdowns).
Halting the function
You can halt the active braking function at any time by tapping the accel\
erator pedal or by turning the steering wheel in a avo id-
ance manoeuvre.
If the driver notices any unusual behaviour in the system, please consul\
t an authorised dealer.
