Driving
– Auto: for an automatic detection of the trailer
length (3 m, 6 m or 9 m).
In Auto mode, an icon appears in the instrument
panel indicating the length detected by the
system.
It may be necessary to make a 90° turn
to allow the system to detect the length
of the trailer.
When a trailer is detected, vehicle detection
when reversing is deactivated.
Operating conditions
– All vehicles are moving in the same direction
and in adjacent lanes.
– The speed of your vehicle is 6 mph (10 km/h)
minimum.
– When you overtake a vehicle, the speed
difference is less than 16 mph (25 km/h).
– When another vehicle overtakes you, the
speed difference is less than 31 mph (50 km/h).
Active Safety Brake with Collision Risk Alert and
Intelligent emergency
braking assistance
Refer to the General recommendations on the
use of driving and manoeuvring aids .


This system:
– warns the driver that their vehicle is at risk of
collision with the vehicle in front.
– reduces the vehicle's speed to avoid a
collision or limit its severity.
This system is comprised of three functions:
– Collision Risk Alert.
– Intelligent emergency braking assistance.
– Active Safety Brake (automatic emergency
braking).


The vehicle has a camera located at the top of
the windscreen.
This system does not avoid the need for vigilance on the part of the driver.
This system is designed to assist the driver
and improve road safety.
It is the driver's responsibility to continuously
monitor the state of the traffic, observing the
driving regulations.
As soon as the system detects a potential obstacle, it prepares the braking
circuit in case automatic braking is needed.
This may cause a slight noise and a slight
sensation of deceleration.
Deactivation / Activation
By default, the system is automatically activated
at every engine start.
This function can be set using the MODE button; select “ON” or “OFF” in the “Active
Safety Brake” menu.
For more information on Vehicle
configuration (MODE) , please refer to
the corresponding section.
Deactivation of the system is signalled by
the illumination of this warning lamp,
accompanied by the display of a message.
Operating conditions and
limits
The ESC system must not be faulty.
The DSC/ASR systems must not be deactivated.
All passenger seat belts must be fastened.
Driving at a steady speed on roads with few
bends is required.
In the following cases, deactivating the system
via the vehicle's configuration menu is advised:
– towing a trailer,
– carrying long objects on roof bars or roof rack,
– with snow chains fitted,
– before using an automatic car wash, with the
engine running,
– before placing the vehicle on a rolling road in
a workshop,
– towed vehicle, engine running,
– following an impact to the windscreen close to
the detection camera.
It is automatically deactivated after
detection of a fault with the brake pedal
switch or with at least two brake lamps.
After an impact, the function automatically stops operating. Contact a
CITROËN dealer or a qualified workshop to
have the system checked.
It is possible that warnings are not given,
are given too late or seem unjustified.
The driver must always stay in control of their
vehicle and be prepared to react at any time
to avoid an accident.
Cases of non-detection by the system:
– Pedestrians, cyclists, animals, objects on the
road.
– Vehicles crossing your lane.
– Vehicles driving in the opposite direction.
