Conditions for operation
- The adaptive cruise control must be active.
- T he vehicle must be travelling in a   traffic 
lane clearly delimited by lines on both sides.
-
 
T
 he ESC system must be operating.
-
 
T
 he ASR /DSC systems must not be 
deactivated.
-
 
N

-
 
A s
 pare wheel of the "space-saver" type 
must not be in use.
-
 
T
 he vehicle must not be subject to strong 
lateral accelerations.
-
 
T
 he direction indicators must not be 
activated.
Activation/Deactivation
The state of the system stays in the 
memory when the ignition is switched off.
The colour of the symbol depends on the 
operating state of the system: (grey colour)
At least one of the operating 
conditions is not met, the system is 
paused.
(green colour)
All operating conditions are met, the 
system is active. If the driver no longer wishes to benefit from 
the system for a
  while, they can deactivate it by 
pressing the button again.
The indicator lamp in the button goes off and 
the symbol disappears from the instrument 
panel.
Cruise control
The driver must hold the steering wheel 
properly.
When cruise control is activated, the symbol is 
displayed in green: by small steering actions, 
the system directs the vehicle and keeps it in 
the position chosen by the driver, in the traffic 
lane.
The driver can feel movements in the steering 
wheel.
This position is not necessarily the centre of 
the lane.
The driver can change the position of the 
vehicle at any time, by turning the steering 
wheel. When the driver feels that the vehicle's 
position is appropriate, whilst keeping hands 
on the steering wheel, they must release the 
pressure to let the system resume control of the 
steering, but the vehicle is not centred within 
the lane automatically.
This function is primarily suitable for driving on 
motor ways and main roads.
F With the adaptive cruise control activated, press this 
button.
The action is confirmed by:
-
 
I
 llumination of the indicator lamp in the button in green.
-
 
D
 isplay of the following symbol in the instrument panel.
(orange colour)
The system has a   fault.

153
Pausing/Suspension of the 
system
The driver must inter vene as soon as 
they believe that the traffic conditions or 
the state of the road sur face make this 
necessary, by moving the steering wheel 
to suspend the system temporarily. Any 
action at the brake pedal which results in 
the cruise control being paused will also 
cause the system to be paused.
If the system detects that the driver is 
not holding the wheel firmly enough, it 
triggers a  series of gradual alerts and then 
deactivates itself if there is no reaction 
from the driver.
After suspension due to the prolonged 
release of the force holding the steering 
wheel, you must reactivate the function by 
pressing the button again. Automatic pausing:
-
 
T
 riggering of the ESC.
-  
P
 rolonged failure to detect one of the lane 
limit markings. In this case, the active lane 
departure warning function can take over, 
and the system will reactivate itself once the 
operating conditions are again met.
On action by the driver: suspension
-
 A
ctivation of the direction indicators.
-
 T
ravelling outside the lane limits.
-
 
T
 oo tight a   grip on the steering wheel or 
dynamic action on the steering wheel.
-
 
A
 ction on the brake pedal (pausing until the 
cruise control is reactivated) or accelerator 
pedal (suspension for as long as the pedal 
is pressed).
-
 
P
 ausing the cruise control.
-
 
D

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 allows:
-
 
t
 he driver to be warned that their vehicle is 
at risk of collision with the vehicle in front, 
a pedestrian or, depending on version, a 
cyclist,
-
 
a c
 ollision to be prevented, or its severity to 
be limited, by reducing the vehicle's speed. 
Driving  
Page 159 of 292

157
The system also takes motorcyclists and 
animals into account; however, animals 
below 0.5  m tall and objects on the road 
are not necessarily detected.
This system is comprised of three functions:
-
 
C
 ollision Risk Alert,
-
 I
ntelligent emergency braking assistance,
-
 
A
 ctive Safety Brake (automatic emergency 
b r ak ing).
The vehicle has a
  multifunctional camera 
located at the top of the windscreen, and, 
depending on version, a radar located in the 
front bumper. 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 system can be deactivated or 
activated via the Driving /Vehicle  
menu of the touch screen.
Deactivation of the system is 
signalled by the illumination of this 
indicator 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:
-
 
t
 owing a   trailer,
-  
c
 arrying long objects on roof bars or roof 
rack,
-
 w
 ith snow chains fitted,
-  
b
 efore using an automatic car wash, with 
the engine running,
-  
b
 efore placing the vehicle on a   rolling road 
in a   workshop,
-  
t
 owed vehicle, engine running,
-  
d
 amaged front bumper (version with radar),
-  
f
 ollowing an impact to the windscreen close 
to the detection camera.
The system is automatically deactivated 
after the use of certain "space-saver" 
type spare wheels is detected (smaller 
diameter).
The system is automatically deactivated 
after detection of a   fault with the brake 
pedal switch or with at least two brake 
lamps.
It is possible that warnings are not given, 
are given too late or seem unjustified.
Consequently, always stay in control of 
your vehicle and be prepared to react at 
any time to avoid an accident.

Collision Risk Alert
It warns the driver if their vehicle is at risk of 
collision with the vehicle in front or a  pedestrian 
present in their traffic lane.
Modifying the alert trigger 
threshold
This threshold determines how you wish 
to be alerted of the presence of a   moving 
or stationary vehicle in front of you, or 
a
  pedestrian or cyclist present in your traffic 
lane.
The current threshold can be 
modified via the Driving /Vehicle  
menu of the touch screen.
You can select one of three predefined 
thresholds:
-
  "Distant ",
-
  "Normal ",
-
  "Close ".
The last threshold selected is memorised when 
the ignition is switched off.
Operation
Depending on the degree of risk of collision 
detected by the system and the alert threshold 
chosen by the driver, several different levels 
of alert may be triggered and displayed in the 
instrument panel.
They take account of the vehicle dynamics, the 
speed of your vehicle and the one in front, the 
environmental conditions and the operation of 
the vehicle (cornering, actions on the pedals, 
etc.) to trigger the alert at the best moment.
Level 1 (orange) : visual alert only, 
signalling to you that the vehicle in 
front is very close.
The " Vehicle close " message is 
displayed.
Level 2 (red) : visual and audible 
alert, warning you that a
  collision is 
imminent.
The message " Brake!" is displayed.
Level 3 : finally, in some cases, a 
haptic alert in the form of micro-
braking can be given, confirming the 
risk of collision. Where the speed of your vehicle is too 
high when approaching another vehicle, 
the level 2
  alert may be displayed 
immediately.
Important:  the level 1
  alert is never 
displayed for a
  stationary obstacle or 
when the " Close" trigger threshold has 
been selected.
Intelligent emergency 
braking assistance
If the driver brakes, but not sufficiently to avoid 
a   collision, this system will supplement the 
braking, within the limits of the laws of physics.
This assistance will only be provided if you 
press the brake pedal.
After an impact, the function automatically 
stops operating. Contact a
 
CITROËN 
dealer or a
 
qualified workshop to have the 
system checked.
