–
 
Driving on a rolling road.
Malfunction
In the event of a malfunction, the 
Service warning lamp comes on 
and this (orange) symbol appears on the 
instrument panel, accompanied by the display of 
a message and an audible signal.
Have it checked by a CITROËN dealer or a 
qualified workshop.
Speed adjustment during 
cornering
(with Highway Driver Assist 2.0)
For more information, refer to the 
General recommendations on the use 
of driving and manoeuvring aids  and the 
Cruise control - particular 
recommendations.
In addition to Adaptive Cruise Control with 
Stop&Go and Lane positioning assist systems, 
this system regulates the speed of the vehicle in 
bends.
It adapts the speed, with or without target 
vehicle, in certain bends on motorways or main 
roads.
The speed is only adjusted if the vehicle speed is 
not compatible with the angle of the bend.
The reduction in speed on a bend is adapted 
to the situation in order to ensure the bend is 
navigated comfortably.
In the presence of a target vehicle, it also 
maintains the inter-vehicle distance.
This system does not manage bends that  are too tight ("hairpin bend" for example).

carriageways with prohibited access for 
pedestrians and cyclists.
–
 
Highway Driver 
 Assist 2.0 activated.
–
 
V
 ehicle speed between 43 and 112 mph (70 
and 180 km/h).
Operation
The vehicle is moving at the 
speed setting and is monitoring 
bends.
The system gradually decreases 
the speed in the bend to 
negotiate it comfortably.
Temporary driver intervention
If the driver believes that the speed is too slow or 
too fast, they can act on the pedals.
Pressing the brake pedal deactivates Highway 
Driver Assist 2.0, while pressing the accelerator 
pedal temporarily suspends it.
Semi-automatic lane 
changing
(with Highway Driver Assist 2.0)
For more information, refer to the 
General recommendations on the use 
of driving and manoeuvring aids .
This system assists the driver in changing lanes.
To do this, it uses the camera located at the top 
of the windscreen, the radar located at the front 
and the four angle radars fitted in the bumpers.
The steering wheel is equipped with a  hands-on detection system to avoid 
distraction on the part of the driver.
For more information on the  Hands-on 
detection, refer to the corresponding section.
The system cannot in any circumstances  replace the need for vigilance on the part 
of the driver. The driver remains responsible 
for their driving by monitoring their 
surroundings and keeping their hands on the 
steering wheel.
The driver must act promptly if they believe 
that the traffic conditions or the state of the 
road surface require their intervention, by 
moving the steering wheel to temporarily 
suspend system operation.
Any intervention on the brake pedal or the 
accelerator pedal that causes the adaptive 
cruise control to be paused or suspended will 
also cause the system to deactivate.
System selection
Two possibilities:
–  Either , when the vehicle is already driving on 
an eligible road, the driver selects the system via 
the Highway Driver Assist 2.0 system activation.
–
 
Or
 , when the driver is already using Highway 
Driver Assist, the vehicle suggests selecting 
the system upon arriving at an eligible road by 
pressing the  OK button.
Activation/Deactivation 
 
► Activate the direction indicator on the side 
corresponding to the lane change, whether or 
not passing the resistance point of the lighting 
control stalk.
The driver can regain control of the vehicle at 
any time:
–
 
by deactivating the direction indicator if the 
vehicle has not yet crossed the line.
–
 
by firmly holding the steering wheel.

Operating conditions
– Eligible roads: roads with separate 
carriageways with prohibited access for 
pedestrians and cyclists.
–
 
The line separating the lanes must be clear 
enough to be identified by the system.

V
 ehicle speed between 43 and 112 mph (70 
and 180 km/h).
Authorised lane change  request
When operating the direction indicator, if the 
necessary conditions are met, the message 
"OK?" is displayed on the instrument panel, 
accompanied by an audible signal.
 
 
 
 
► After checking the surroundings, press 
2-OK  to confirm the start of the lane change 
manoeuvre.
The message "Stay alert"
  is displayed as a 
reminder that the driver is responsible for the 
manoeuvre.
 
 
The system then proceeds with the vehicle’s 
lane change.
Once the manoeuvre has been carried out, the 
system is automatically deactivated and the lane 
positioning assist takes over.
If the direction indicator has been set beyond the 
point of resistance, the driver must pull it back.
The driver must hold the steering wheel  correctly.
As soon as the semi-automatic lane change 
begins, the system directs the vehicle to the 
target lane by small actions on the steering to 
position it in the destination lane.
You can feel the steering wheel moving.
Interruption of lane change
It is possible that during a lane change, the 
necessary conditions for the functioning of the 
system may no longer be met.
 
 
If this occurs before either wheel has crossed 
the line between the two lanes, the system will 
automatically return the vehicle to its original 
lane (confirmed by displaying a manoeuvre 
cancellation message on the digital instrument 
panel and an audible signal). Then the system 
automatically deactivates itself.
 
 
If this occurs while the lane change has begun, 
the system asks the driver to immediately 
regain control of the vehicle (confirmed by the 
display of a message on the digital instrument

panel and an audible signal). Then the system 
automatically deactivates itself.Refused lane change 
request
When pressing 2-OK, if the necessary conditions 
are not met, the lines appear in orange on the 
instrument panel, accompanied by an audible 
signal.
 
 
The system keeps the vehicle in the original 
lane. The system is deactivated and the semi-
automatic lane change is not carried out.

Active Safety Brake with  Collision Risk Alert and 
Intelligent emergency 
braking assistance
For more information, 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 preceding vehicle, a pedestrian 
or a cyclist.
–
 
reduces the vehicle's speed to avoid a 
collision or to limit its severity
.
The speed will be reduced by a maximum of 16 mph (25 km/h) (versions 
with camera only) or by a maximum of 31 
mph (50 km/h) (versions with camera and 
radar).
The system also takes motorcyclists into  account. It may also react on animals. 
Animals (especially animals smaller than 
0.5
 
m) and objects on the road are not 
necessarily detected.
This system includes three functions:
–  Collision  Risk Alert.
–
 
Intelligent emergency braking assistance 
(iEBA).
–
 
Active Safety Brake (automatic emergency 
braking).
 
 
The vehicle has a multifunction camera located 
at the top of the windscreen and, depending on 
version, a radar located in the front bumper.
This system does not replace the need  for driver vigilance.
This system is designed to assist the driver 
and improve road safety.
It is the driver's responsibility to continuously 
monitor traffic conditions in accordance with 
applicable driving regulations.
As soon as the system detects a  potential collision, it prepares the braking 
circuit. This may cause a slight noise and a 
slight sensation of deceleration.

Driving
6Deactivation/Activation
By default, the system is automatically activated 
at every engine start.
It is configured in the ADAS touch screen 
application.
Deactivation of the system is signalled by 
the illumination of this warning lamp, 
accompanied by the display of a message.
Operating conditions and 
limits
Vehicle moving forward without trailer.
Brake system operational.
ASR / ESP system activated.
Seat belts fastened for all passengers.
Stabilised speed on roads with no or low 
curvature.
This warning lamp lights up on the  instrument panel without any additional 
message, to indicate that the “automatic braking 
system” is not available. This is a normal 
behavior indicating that a condition is not fulfilled 
and which does not request the support of a 
workshop. 
In any situations with ignition on where automatic 
braking presents a risk, deactivating the 
system via ADAS touch screen application is 
recommended, for instance:
–
 
T
owing a trailer (particularly a trailer without its 
own braking system).
–
 
Carrying long objects on roof bars.
–
 
Driving with snow chains.
– Using an automatic car wash.
–  Performing any maintenance (e.g. changing a 
wheel, working underhood).
–
 
Placing the vehicle on a rolling bench in a 
workshop.
–
 
T
 owing the vehicle.
–
 
Following a front bumper deformation (version 
with radar).
–
 
Following 
 an impact to the windscreen close to 
the detection camera.
The system is automatically deactivated  if:
–
 
A
 spare wheel with a too small diameter is 
detected.
–
 
A
 fault with the brake pedal switch or with 
the right or left brake lamp is detected.
–
 
A
 fault in the sensors, in the electronic or in 
the brake system is detected.
–
 
A
 trailer is detected by the equipped vehicle 
hitch (with an electrical connection plug).
The system diagnoses permanently its  capability and may inhibit itself without 
specific driver indication, if the system is 
outside of the regular operating conditions. 
Examples: sensor initialization, board voltage 
out of regular range, activation of stability 
system… 
Therefore the system may not be available 
just after starting the vehicle. 
It can be dangerous to drive if the brake 
lamps are not in perfect working order.
The driver must not load his vehicle  excessively (respect of MTAC values, 
MTRA values and loading height on roof 
bars).
Following an impact (e.g. a collision), the 
system is automatically deactivated.
Have it checked by a CITROËN dealer or a 
qualified workshop.
Collision Risk Alert
This function warns the driver if there is a risk 
of collision with the preceding vehicle, or with a 
pedestrian or cyclist.
Modifying the alert trigger threshold
The trigger threshold determines the sensitivity 
with which the function warns of the risk of 
collision.
It is configured in the ADAS touch screen 
application.
►
 
Select one of the 3 preset thresholds: “ Far
”, 
“Medium” or “Near”.
The selected threshold is memorised when the 
ignition is switched off.
Operation
Depending on the collision risk detected by the 
system and the alert trigger threshold chosen    
Page 128 of 228

126
Driving
by the driver, different levels of alert may be 
triggered and displayed on the instrument panel.
The system takes into account the vehicle 
dynamics, the difference speed of the own 
vehicle and the object identified for the collision 
risk, and the operation of the vehicle (actions on 
the pedals, steering wheel, etc.) to trigger the 
alert at the most relevant moment.
(orange)
Level 1: visual alert only, warning that the 
preceding vehicle is very close.
The message
  "Vehicle close" is displayed.
(red)
Level 2: visual and audible alert, warning 
that a collision is imminent.
The message "Brake! " is displayed.
Level 3: a micro-braking may be given, 
confirming the risk of collision (optional).
While approaching a vehicle too quickly, 
the level 2 alert may be displayed 
directly.
Important: the level 1 alert depends on the 
trigger threshold selected. It reacts only on 
moving vehicles. It is disabled automatically 
at lower speed.
It is possible that collision warnings are 
not given, are given too late or seem 
unjustified.
The driver must always stay in control of the 
vehicle and be prepared to react at any time 
to avoid an accident.
If you select “Far” in the ADAS touch 
screen application, then the system 
warns sooner. This increases the safety but 
increases also the amount of alerts, if the 
legal safety distance is not kept. To reduce 
the alert occurrence, you can change the 
setting to “Medium” or “Near”.
Intelligent emergency 
braking assistance (iEBA)
This function increases vehicle deceleration 
if the driver doesn't brake enough to avoid a 
collision.
This assistance is only provided if the driver 
presses the brake pedal.
Active Safety Brake 
 
This function, also called "automatic emergency 
braking", intervenes after the acoustic alert if the 
driver does not operate the brake pedal quickly 
enough.
The system aims at reducing the speed of 
impact or avoiding a collision if the driver fails to 
react.
The speed will be reduced by a  maximum of 16 mph (25 km/h) (versions 
with camera only) or by a maximum of 31 
mph (50 km/h) (versions with camera and 
radar).

Driving
6Operation
The system operates subject to the following 
conditions:
– 
The vehicle's speed does not exceed 50 
mph (80 km/h) when a pedestrian or a cyclist is 
detected.
–
 
The vehicle's speed does not exceed 50 mph 
(80 km/h) when a stationary vehicle is detected.
–
 
The vehicle's speed is between 6 mph and 
53 mph (10
  km/h and 85 km/h) (versions with 
camera only) or 87 mph (140 km/h) (versions 
with camera and radar) when a moving vehicle 
is detected.
This warning lamp flashes (for  approximately 10 seconds) as soon as 
the function applies the vehicle’s brakes. During 
the flashing time, the function is not available.
In the event of automatic emergency braking, 
keep the brake pedal depressed, also after a 
complete stop is reached, to prevent the vehicle 
from rolling away.
The driver can override the "automatic  emergency braking" at any time by firmly 
turning the steering wheel and/or firmly 
depressing the accelerator pedal.
The brake pedal may feel hard and  vibrate slightly while the function is 
operating.
If the vehicle comes to a complete stop, 
automatic braking is maintained for 1 to 2 
seconds.
Turning scenarios
Crossing road with another vehicle 
 
The system may operate when the vehicle is 
turning and detects another vehicle, on the 
adjacent lane, approaching from the opposite 
direction if:
–
 
The corresponding direction indicator is 
activated.
–
 
Then the vehicle is about to cross the path of 
another vehicle.
–
 
The vehicle speed is between 3 and 12
   mph 
(5 and 20
  km/h).
–
 
A
  collision on the side of the other vehicle is 
probable.
Crossing road with a pedestrian 
 
The system may operate when the vehicle 
is turning left or right and detects a crossing 
pedestrian if: 
–
 
The pedestrian is crossing in front of the 
vehicle.
–
 
The pedestrian can clearly be detected by the 
sensors.
–
 
The scenery is detectable by the sensors (e.g. 
brightness, contrast vs background).
–
 
The vehicle speed is between 3 and 15
   mph 
(5 and 25
  km/h).
Malfunction
This warning lamp lights up on the instrument panel with the message 
"Sensor blind" in certain cases. With the variant 
"camera only", the system is deactivated. With 
the variant "camera and radar", the system may 
continue to operate in a degraded mode. This 
may be caused by a reduced visibility (rain, fog, 
snow, blending by low sun…) or by a real sensor 
blockage. In this case, stop the vehicle and verify    
Page 130 of 228

128
Driving
if the front camera or the front radar is covered 
by dirt, snow, ice or anything preventing the 
sensing.
In the event of a malfunction, this warning 
lamp lights up on the instrument panel, 
accompanied by the display of a message and 
an audible signal.
Have it checked by a CITROËN dealer or a 
qualified workshop.
If these warning lamps come on 
after the engine has been switched 
off and then restarted, contact a CITROËN 
dealer or a qualified workshop to have the 
system checked.
These warning lamps light up on  the instrument panel and/or in the 
warning lamp display for seat belts and front 
passenger airbag to indicate that the driver's 
and/or front passenger's seat belt is not fastened 
(depending on version). The automatic braking 
system is deactivated until the seat belts are 
fastened.
Distraction detection
For more information, refer to the 
General recommendations on the use 
of driving and manoeuvring aids .
The function comprises the "Coffee Break Alert" 
system combined with the "Driver Attention 
Warning" system.
These systems are in no way designed  to keep the driver awake or to prevent 
the driver from falling asleep at the wheel. 
It is the driver’s responsibility to stop if feeling 
tired.
Take a break if you are feeling tired or at least 
every 2 hours.
Activation/Deactivation
By default, the function is automatically activated 
at every engine start.
It is configured in the ADAS touch screen 
application.
Coffee Break Alert
The system triggers an alert when it  detects that the driver has not taken a 
break after two hours of driving at a speed above 
43 mph (70
  km/h).
This alert is issued via the display of a message 
encouraging the driver to take a break, 
accompanied by an audible signal.
If the driver does not follow this advice, the alert 
is repeated hourly until the vehicle is stopped.
The system resets itself if one of the following 
conditions is met:
–
 
With the engine running, the vehicle has been 
stationary for more than 15 minutes.
–
 
The ignition has been switched off for a few 
minutes.
–
 
The driver's seat belt is unfastened and their 
door is opened.
As soon as the speed of the vehicle  drops below 43   mph (70   km/h), the 
system goes into standby.
Driving time starts being counted again once 
the speed reaches above 43
  mph (70   km/h).
Driver Attention Warning 
 
The system assesses the driver's level of alertness, fatigue and distraction by 
identifying trajectory changes in relation to the 
lane markings.
To do this, the system uses a camera, placed on 
the upper part of the windscreen.
This system is particularly suited to fast roads 
(speed higher than 43 mph (70
  km/h)).
At a first alert level, the driver is warned by 
the message "Caution!“, accompanied by an 
audible signal.
After three first-level alerts, the system triggers 
a further alert with the message " Driving
