ELECTRONIC PARKING BRAKE (2/3)
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 apply the electronic parking brake
manually (when stopping at a red light,
or stopping when the engine is running,
etc.): pull and release the switch 3. The
brake is released as soon as the vehi-
cle is started up again.
Special cases
To park on a slope or while towing a
trailer, for example, pull switch 3 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 si- multaneously depressing the brake
pedal and the switch 3, stop the
engine (do not put it on standby for
vehicles fitted with Stop and Start);
– in gear, release the brake pedal and switch 3.
Manual operationYou can control the electronic parking
brake manually.
Applying the electronic parking
brake
Pull switch 3. Warning light 4 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 3: indicator
lights 4 and
} go out.
Special feature related to
the Stop and Start function:
if the driver's seat is unfas-
tened before the engine
goes into standby due to the Stop
and Start function, make sure that
the parking brake is applied: the
} indicator light on the instru-
ment panel confirms this. Risk of
loss of immobilisation.

ELECTRONIC PARKING BRAKE (3/3)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.
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 3 (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 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 (5/6)
– Bad weather, flooded roads:
Do not drive through
floods if the water is
above the lower edge of
the wheel rims.

2.35
DRIVER CORRECTION DEVICES AND AIDS (1/5)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;
– hill start assistance.
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).

DRIVER CORRECTION DEVICES AND AIDS (2/5)
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
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.

DRIVER CORRECTION DEVICES AND AIDS (3/5)
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 the direction se-
lected by the driver and the actual di-
rection of the vehicle and corrects this
as necessary by applying the brakes
selectively and/or acting on the engine
power. If the system is triggered, the
 indicator light flashes on the in-
strument 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.

2.38
DRIVER CORRECTION DEVICES AND AIDS (4/5)
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.

2.39
DRIVER CORRECTION DEVICES AND AIDS (5/5)
Hill start assistance
Depending on the gradient of the in-
cline, this system assists the driver
when starting on a hill. It prevents the
vehicle from rolling backwards by au-
tomatically applying the brakes when
the driver lifts his/her foot off the brake
pedal to depress the accelerator pedal.
System operation
It only operates when the gear lever is
in a position other than neutral (other
than N or P for automatic transmis-
sions) and the vehicle is completely
stationary (brake pedal depressed)
The system holds the vehicle for ap-
proximately 2 seconds. The brakes are
then released (the vehicle will move ac-
cording to the slope).
The hill start assistance
system cannot completely
prevent the vehicle from
rolling backwards in all sit-
uations (extremely steep gradients,
etc.).
In all cases, the driver may depress
the brake pedal to prevent the vehi-
cle from rolling backwards.
The hill start assistance function
should not be used for prolonged
stops: use the brake pedal.
This function is not designed to im-
mobilise the vehicle permanently.
If necessary, use the brake pedal to
stop the vehicle.
The driver must remain particularly
vigilant when driving on slippery or
low-grip surfaces.
Risk of serious injury.

2.40
ACTIVE EMERGENCY BRAKING (1/7)
Using information from the radar-cam-
era 1, the system calculates the dis-
tance which separates it from the
vehicle in front and the surrounding pe-
destrians.
It notifies the driver if there is a risk of
head-on collision. The driver can then
brake the vehicle to limit the damage
arising from a collision.
Note: make sure the windscreen is not
obscured (dirt, mud, snow, condensa-
tion etc.).
1
This function is an addi-
tional driving aid. This func-
tion is not under any circum-
stances intended to replace
the due care and attention of the
driver, who should at all times be
in control of the vehicle.
This system can apply maximum
braking to the vehicle until it is
completely stationary if necessary.
For safety reasons, always wear
your seat belt when travelling in
your vehicle and make sure that it
is loaded so that no items can be
thrown forward and hit the occu-
pants.

2.41
Special features
When the vehicle speed:
– is less than 27.9 mph (45 km/h) ap-
proximately, the warning and brak-
ing are activated at the same time;
– is between about 27.9 mph
(45 km/h) and 48 mph (80 km/h)
approximately, the warning is acti-
vated. Braking will only be triggered if
the vehicle preceding you is moving.
Braking is not activated for stationary
vehicles;
– is between about 48 mph (80 km/h)
and 99.2 mph (160 km/h) , the warn-
ing and braking are only triggered if
the vehicle preceding you is moving.
The warning and braking are not ac-
tivated for stationary vehicles;
– is above 99.2 mph (160 km/h), the
system is not active.
ACTIVE EMERGENCY BRAKING (2/7)
Detection of vehicles
Operation
When driving (speed between about
4.34 and 99.2 mph (7 and 160 km/h)), if
there is a risk of collision with the vehi-
cle in front, the system:
– warns you of a collision risk:
– the warning light
\b is dis-
played in red on the instrument
panel, accompanied by a beep;
or
– the indicator 2 is displayed in red
on the instrument panel and, de-
pending on the vehicle, on the head
up display, accompanied by a beep.
If the driver depresses the brake
pedal and the system still detects a
risk of collision, the brake force is in-
creased.
– triggers braking:
if the driver fails to react following the alert and collision becomes im-
minent.
2
You can interrupt braking at any
point by:
– tapping the accelerator pedal;
or
– turning the steering wheel in an avoidance manoeuvre.
