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.

2.44
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.

2.55
BLIND SPOT WARNING (1/4)
This system alerts the driver to other
vehicles in the detection zone A.
The system is activated when the vehi-
cle’s speed is between approximately
30 km/h (19 mph) and 140 km/h (87
mph).
This function uses sensors 1 installed in
the front and rear bumper of both sides.
1
A
Special featureMake sure that the sensors are not ob-
scured (by dirt, mud, snow, etc.).
If a sensor is obscured, the message
“Blind spot clean sensor” will appear on
the instrument panel. Clean the sen-
sors.
AThis function is an addi-
tional aid which indicates
other vehicles in the blind
spot area.
It can never in any case be a sub-
stitute for care nor for the driver’s
responsibility while in charge of his
vehicle.
The driver should always be ready
for sudden incidents while driv-
ing: always ensure that there are
no small, narrow moving obstacles
(such as a child, animal, pushchair,
bicycle, stone, post etc.) in the blind
spot when manoeuvring.

2.58
Operating faults
If the system detects a fault, the mes-
sage “Check blind spot alert” is dis-
played on the instrument panel. Consult
an approved dealer.
Note: when the engine is started, the
indicator light 6, display B , flashes
three times. It is normal.
– The system’s detection
range operates according
to a standard lane width. If
you are driving in wide traf-
fic lanes, the system might not
be able to detect a vehicle in the
blind spot.
– The system might be disrupted momentarily if it is exposed to
strong electromagnetic waves
(as beneath high-tension power
lines) or to very poor weather
conditions (heavy rain, snow
etc.). Remain aware of driving
conditions.
There is a risk of accidents.
BLIND SPOT WARNING (4/4)
Because sensors have
been installed in the bump-
ers, any work (repairs, re-
placements, touching up of
paintwork) must be carried out by a
qualified professional.

Conditions for non-function
– If the object is not moving;
– if traffic is heavy;
– the road is winding;
– if front and rear sensors both detect an object at the same time (e.g.
when passing an articulated lorry).

2.60
SAFE DISTANCE ALERT (2/3)
The measurement is dis-
played for information only:
the system performs no
action on the vehicle.
This function is not designed for use
in urban conditions or for a dynamic
driving style (sudden cornering, ac-
celeration, braking, etc.), but rather
for stable driving conditions.
The function does not interact with
the braking system.
The windscreen must remain clean
to ensure the correct operation of
the system.
– C (orange): the time interval falls
between around 1 and 2 seconds (in-
sufficient distance between the two
vehicles);
– D (red): the time interval is less than
or equal to around one second (very
insufficient distance between the two
vehicles).
If the interval between the two vehicles
is less than around 0.5 seconds, noti-
fication 4, display D , will flash on the
instrument panel. Under certain condi-
tions, the time interval may not be dis-
played:
– while cornering;
– when changing lane;
– if the vehicle in front is sufficiently far or outside the range of the sensor.
This function is essential if adaptive
cruise control is activated.
On equipped vehicles, some infor-
mation is given on the head-up dis-
play.

Operation
Upon activating the function, indicator 4
notifies the driver of the distance sepa-
rating them from the vehicle in front.
– A (grey): function not operational;
– A (green): no vehicle detected;
– B (green): the time interval is greater
than or equal to around two seconds
(distance between the two vehicles
adapted to your speed);

2.82
PARKING DISTANCE CONTROL (1/5)
Operating principle
Ultrasonic sensors in the rear bumper
measure the distance between the ve-
hicle and an obstacle.
This measurement is indicated by
beeps which become more frequent the
closer you come to the obstacle, until
they become a continuous beep when
the vehicle is approximately 20 to
30 centimetres from the obstacle.
The system detects obstacles to the
front, the rear and the sides of the ve-
hicle.
The parking distance control system
is only activated when the vehicle is
driven at a speed below approximately
6 mph (10 km/h).
The parking distance control system
does not take into account towing and
load carrying systems etc.
This function is an addi-
tional aid that indicates the
distance between the vehi-
cle and an obstacle whilst
reversing, using sound signals.
Under no circumstances should it
replace the driver’s care or respon-
sibility whilst reversing.
The driver should always be ready
for sudden incidents while driv-
ing: always ensure that there are
no small, narrow moving obstacles
(such as a child, animal, pushchair,
bicycle, stone, post etc.) in the blind
spot when manoeuvring.
Special features
Ensure that the ultrasonic sensors indi-
cated by arrows 1 are not obscured (by
dirt, mud, snow, etc.).

2.86
Automatic deactivation of the
parking distance control
The system deactivates:
– when the vehicle speed is above ap-proximately 6 mph (10 km/h);
– depending on the model, when the vehicle is stationary for more than
approximately 5 seconds and an ob-
stacle is detected (such as when in a
traffic jam, etc.);
– when the vehicle is in neutral for manual gearboxes, or in position N
or P for automatic gearboxes.
PARKING DISTANCE CONTROL (5/5)
Operating faults
When the system detects an operating
fault, a beep sounds for approximately
3 seconds each time reverse gear is
selected and is accompanied by the
message “Check parking sensor” on
the instrument panel. Consult an ap-
proved dealer

ASSISTED PARKING (4/4)
This function is an additional driving aid. This function is not under any circumstances intended to replace the due\
care
and attention of the driver, who should at all times be in control of the vehicle.
Make sure that the manoeuvre complies with the applicable traffic regulations at your location.
– The driver should always be ready for sudden incidents while driving: al\
ways ensure that there are no small, narrow moving obstacles (such as a child, animal, pushchair, bicycle, stone, post etc.) in the blind spot when manoeuvring.
– The system cannot detect objects located in the sensor blind spots.
– When manoeuvring, the steering wheel may turn quickly: do not put your h\
ands inside, and make sure that nothing is caught inside.
– Always visually check that the parking space proposed by the system is s\
till available and contains no obstacles.
– The system should only be used when towing a trailer or when there is a \
towing or load carrying system on the vehicle.
