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.

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.

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.

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.

2.44
ACTIVE EMERGENCY BRAKING (5/7)
Conditions for non-activation
of the system
The system cannot be activated:
– when the gear lever is in neutral;
– when the parking brake is activated;
– while cornering.
As a general rule, if the driver shows
signs of attention (action on the steering
wheel, pedals etc.), the system delays
its operation or does not activate.
Operating faults
When the system detects an operating
fault, the
\b warning light lights up
on the instrument panel, with the mes-
sage “Active braking disconnected”.
Consult an approved dealer
Temporarily not available
When the system detects a tempo-
rary unavailability, the
\b warning
light lights up on the instrument panel
accompanied by the message “Active
braking: sensor blind” or, depending on
the vehicle, “Radar-camera: no visibil-
ity”.
The possible causes are:
– the system is temporarily blinded (glare from the sun, dipped beam
headlights, bad weather conditions
etc.). The system will be operational
again when visibility conditions are
better;
– the system is temporarily disrupted (for example: windscreen obscured
by dirt, ice, snow etc.). In this case,
park the vehicle and switch off the
engine. Clean the windscreen. When
you next start the engine, the warn-
ing light and the message go out;
– if this is not the case, this may arise from another cause; contact an
Approved Dealer.

2.46
ACTIVE EMERGENCY BRAKING (7/7)
Limitation of the system operation
– A vehicle travelling in the opposite direction will not trigger any alert\
or any action on the system operation.
– The radar-camera area on the windscreen should be kept clean and free of\
any modifications in order 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.
– The system may not operate properly when the road surface is slippery (\
rain, snow, black ice etc.).
– To ensure correct operation, the system needs to distinguish the complete\
outline of the pedestrian. So the system cannot detect:
– pedestrians in the darkness or in poor lighting conditions;
– partially visible pedestrians:
– pedestrians less than approximately 80 cm tall;
– pedestrians carrying large objects;
– ...
Deactivating the function
You must disable the function if:
– the brake lights are not functioning;
– the area of the radar-camera has been damaged (on the windscreen side o\
r the interior rear-view mirror side);
– the vehicle is being towed (breakdowns);
– the windscreen is cracked or distorted (do not carry out repairs on thi\
s area of the windscreen; have it changed by an Authorised Dealer).
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.
In the event of the system behaving abnormally, deactivate it and consult an authorised dealer.
