When the vehicle automatically locks itself
again (as happens if a door or boot is not
opened within 30 seconds of unlocking),
the monitoring system is automatically
reactivated.
Triggering of the alarm
This is indicated by sounding of the siren
and flashing of the direction indicators for
30 seconds.
The monitoring functions remain active until
the alarm has been triggered eleven times
consecutively.
When the vehicle is unlocked using the remote
control or the
K
eyless Entry and Starting
system, rapid flashing of the locking button
indicator lamp informs you that the alarm
was triggered during your absence. When
the ignition is switched on, this flashing stops
immediately.

Electronic stability control
(ESC)
Electronic stability control integrating the
following systems:
-
a
nti-lock braking system (ABS) and
electronic brake force distribution (EBFD),
-
em

ergency braking assistance (EBA),
-

w
heel anti-slip regulation (ASR) or traction
control,
-
d

ynamic stability control (DSC).
Definitions
Anti-lock braking system (ABS)
and electronic brake force
distribution (EBFD)
This system improves the stability and
manoeuvrability of your vehicle when braking and
contributes towards improved control on corners, in
particular on poor or slippery road sur faces.
The ABS prevents wheel lock in the event of
emergency braking.
The electronic brake force distribution system (EBFD)
manages the braking pressure wheel by wheel.
Emergency braking assistance
(EBA)
In an emergency, this system permits the
optimum braking pressure to be reached
more quickly, therefore reducing the stopping
distance.
It is triggered in relation to the speed at which
the brake pedal is pressed. The effect of this is
a reduction in the resistance of the pedal and
an increase in braking efficiency.
Anti-slip regulation (ASR)
The ASR system (also known as Traction
Control) optimises traction in order to limit
wheel slip by acting on the brakes of the driving
wheels and on the engine. It also improves
the directional stability of the vehicle on
acceleration.
Dynamic stability control (DSC)
If there is a difference between the path
followed by the vehicle and that required by
the driver, the DSC monitors each wheel and
automatically acts on the brake of one or more
wheels and on the engine to return the vehicle
to the required path, within the limits of the laws
of physics.
If you benefit from the Citroën Connect
Box offer with the SOS and assistance
pack included, there are additional
ser vices available to you in your personal
space, via the website for your country.
Anti-lock braking system
(ABS) and electronic brake
force distribution (EBFD)
The fixed illumination of this warning
lamp indicates that there is a fault
with the ABS.
If this warning lamp comes on, in
conjunction with the STOP
and
ABS warning lamps, an audible
signal and a message, this indicates
that the electronic brake force
distribution (EBFD) is faulty.
You must stop as soon as it is
safe to do so.
In both cases, have the system
checked by a CITROËN dealer or
a qualified workshop as soon as
possible.
When changing wheels (tyres and rims),
ensure that these are approved for your
vehicle.
Normal operation of the ABS may make
itself felt by slight vibration of the brake
pedal.
If you need to brake in an emergency,
press the brake pedal ver y firmly and
keep the pressure applied.
Safety

121
Driver inattention alert
Using a camera placed at the top
of the windscreen, the system
assesses the driver's level of
vigilance by identifying variations
in trajectory compared to the lane
markings.
This system is particularly suited to fast roads
(speed higher than 40 mph (65 km/h)).
When the system interprets the behaviour of
the vehicle as indicating a certain fatigue or
inattention threshold on the part of the driver, it
triggers the first level of alert. After three first level alerts, the system triggers
a new alert with the message "
Take a break!",
accompanied by a more pronounced audible
signal.
In certain driving conditions (poor road
sur face or strong winds), the system may
give alerts independent of the driver's
level of vigilance. The following situations may interfere with
the operation of the system or prevent it
working:
-

p
oor visibility (inadequate lighting of
the roadway, falling snow, heavy rain,
dense fog, etc.),
-
d
azzle (headlamps of an oncoming
vehicle, low sun, reflections on a damp
road, leaving a tunnel, alternating
shade and light, etc.),
-
w
indscreen area located in front of the
camera: dirty, misted up, frost-covered,
snow-covered, damaged or covered by
a s t i c ke r,
- l ane markings absent, worn, hidden
(snow, mud) or multiple (roadworks,
e t c .),
-

c
lose to the vehicle ahead (lane
markings not detected),
-

r
oads that are narrow, winding, etc.
The driver is then alerted by the message
"
Ta k e c a r e ! ", accompanied by an audible
signal.

It supplements the audible assistance,
regardless of the vehicle's path, by displaying
on the screen those whose location represents
the distance between the obstacle and the
vehicle (white: more distant obstacles, orange:
close obstacles, red: very close obstacles).
When the obstacle is very close, the "Danger"
symbol is displayed on the screen.
Front parking sensors
In addition to the rear parking sensors, the
front parking sensors are triggered when an
obstacle is detected in front and the speed of
the vehicle is still below 6 mph (10 km/h).
The front parking sensors are interrupted if
the vehicle stops for more than three seconds
in for ward gear, if no further obstacles are
detected or when the speed of the vehicle
exceeds 6 mph (10 km/h).The sound emitted by the speaker (front or
rear) locates the obstacle in relation to the
vehicle – in the vehicle trajectory, in front
or behind.
Activation/Deactivation
The system is activated or deactivated via the
vehicle configuration menu. F

I
n the Driving/Vehicle
menu
of the touch screen, select the
" Driving functions " tab, then
deactivate/activate " Parking
sensors ".
The system will be deactivated
automatically if a trailer is attached or a
bicycle carrier is fitted on a towbar (vehicle
fitted with a towbar installed in line with
the manufacturer's recommendations).
The parking sensors are deactivated while
the Park Assist system is measuring a
space.
For more information on Park Assist ,
refer to the corresponding section.
Operating limits
- Certain obstacles located in the sensors' blind spots may not be detected or no
longer be detected during the manoeuvre.
-

S
ounds such as those emitted by noisy
vehicles and machinery (e.g. lorries,
pneumatic drills, etc.) may inter fere with the
vehicle's sensors. -

C
ertain materials (fabrics) absorb sound
waves: pedestrians may not be detected.
-
A
ccumulated snow or dead leaves on the
road sur face can inter fere with the vehicle's
sensors.
-
A f
ront or rear impact to the vehicle can
distort the settings of the sensors, which is
not always detected by the system: distance
measurements may be incorrect.
-
T
he tilting of the vehicle if the boot is
very loaded can affect the distance
measurements.
-
T
he sensors may be affected by poor
weather conditions (heavy rain, thick fog,
snowfall, etc.).
Recommendations on care
In bad or wintry weather, ensure that the
sensors are not covered with mud, ice or
snow. When reverse gear is engaged, an
audible signal (long beep) indicates that
the sensors may be dirty.
