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.

2.41
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.

2.42
Detection of pedestrians
Operation
When driving (speed between about
4.2 mph (7 km/h) and 36 mph (60 km/h),
when there is a risk of impact with a pe-
destrian:
– the warning light
\b is displayed
in red on the instrument panel, ac-
companied by a beep;
or
– the indicator 3 is displayed in red on
the instrument panel and, depending
on the vehicle, on the head up dis-
play, accompanied by a beep.

ACTIVE EMERGENCY BRAKING (3/7)
When the impact is imminent, the
system activates the braking.
The system can apply maximum brak-
ing to the vehicle until it is completely
stationary if necessary.

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.
