Cruise control - Specific 
recommendations
The cruise control function does not  guarantee compliance with the maximum 
authorised speed and the safety distance 
between vehicles, the driver remains 
responsible for their driving.
In the interest of public safety, only use cruise 
control if the traffic conditions enable vehicles 
to drive at a steady speed and maintain an 
adequate safety distance.
Remain vigilant while cruise control is 
activated. If you press and hold one of the 
speed setting modification buttons, your 
vehicle may change speed very abruptly.
When descending a steep hill , the cruise 
control system cannot prevent the vehicle 
from exceeding the set speed. Brake if 
necessary to control the vehicle speed.
On steep climbs or when towing, the set 
speed may not be reached or maintained.
Exceeding the programmed speed 
setting
You can temporarily exceed the speed 
setting by pressing the accelerator pedal (the 
programmed speed flashes).
To return to the speed setting, release the 
accelerator pedal (when the set speed is 
reached again, the displayed speed stops 
flashing).
Operating limits
Never use the system in the following 
situations:
–
 
In an urban area with the risk of 
pedestrians crossing the road.
–
 
In heavy traffic (except versions with the 
Stop & Go function).
–
 
On winding or steep roads.
–
 
On slippery or flooded roads.
–
 
In poor weather conditions.
–
 
In the event of restricted visibility for the 
driver
.
–
 
Driving on a speed circuit.
–
 
Driving on a rolling road.
–
 
When using a ‘space-saver
 ’ type spare 
wheel.
–
 
When using snow chains, non-slip covers 
or studded tyres.
Cruise control
For more information, refer to the 
General recommendations on the use 
of driving and manoeuvring aids  and 
to
 
Cruise control - particular 
recommendations.
This system automatically maintains the  vehicle’s speed at the value programmed 
by the driver (speed setting), without the use of 
the accelerator pedal.
Cruise control is switched on manually.
It requires a minimum vehicle speed of 25 mph 
(40
 
km/h).
With an automatic gearbox, mode
 
D
  or second 
gear or higher in mode
 
M
  must be engaged.
Cruise control remains active after 
changing gear on engines fitted with Stop 
& Start.
Switching off the ignition cancels any 
speed setting.

Highway  Driver Assist
Only available on versions with automatic 
gearbox.
This system automatically adjusts the speed 
and corrects the trajectory of the vehicle, using 
the Adaptive Cruise Control with Stop&Go in 
conjunction with the Lane Positioning Assist.
These two functions must be activated and in 
operation.
This system is especially suitable for driving on 
motorways and main roads.
For more information on  Adaptive cruise 
control and Lane Positioning Assist, refer to 
the corresponding sections.
The system assists the driver by acting  on the steering, acceleration and braking 
within the physical limits
  and capacities of the 
vehicle. Certain road infrastructure elements 
or vehicles in the surroundings may not be 
properly seen or may be poorly interpreted by 
the camera and radar, resulting in an 
unexpected change in direction, a lack of 
steering correction and/or inappropriate 
management of acceleration or braking.

Adaptive cruise control
For more information, refer to the 
General recommendations on the use 
of driving and manoeuvring aids  and 
to
 
Cruise control - particular 
recommendations.
This system automatically maintains the vehicle 
speed at a value set by the driver (speed 
setting), while respecting a safety distance from 
the vehicle in front (target vehicle) previously set 
by the driver. The system automatically manages 
the acceleration and deceleration of the vehicle.
With the Stop
  &   Go function, the system 
manages braking until the vehicle comes to a 
complete stop and the restarting of the vehicle.
The brake lamps come on if the vehicle  is slowed down by the system.
The system is not operational in the event of 
a brake lamp failure.
 
 
To do this, the system uses a camera fitted at the 
top of the windscreen and a radar fitted in the 
front bumper.
Primarily designed for driving on main 
roads and motorways, this system only 
works with moving vehicles driving in the 
same direction as your vehicle.
If the driver activates the direction 
indicator to overtake a slower vehicle, 
cruise control may temporarily reduce the 
distance to the target vehicle to facilitate 
overtaking, without exceeding the speed 
setting.

following recommendations apply:
–
 
The driver should not leave the vehicle.
–
 
Do not open the boot.
–
 
Do not drop off or pick up passengers.
–
 
Do not engage reverse gear
 .
When restarting the vehicle, beware of 
cyclists, pedestrians or animals who are 
not taken into account by the system.
The driver must monitor their surroundings.
Operating limits
Cruise control operates by day and night, in dry 
weather or moderate rainfall.
Certain situations cannot be managed by the 
system and require driver intervention.
Cases not taken into account by the system:
–
 
Pedestrians, cyclists, animals.
–
 
Stationary vehicles (e.g.
   traffic jams, 
breakdown).
 
 
– Vehicles crossing your lane.
–  V ehicles driving in the opposite direction.
Situations where the driver must suspend the 
system:
 
 
– Vehicles in a tight bend.
–  When approaching a roundabout. 
 
– When following a narrow vehicle.
Reactivate the system when conditions allow .
Situations in which the driver is prompted to 
immediately resume control:
–
 
Excessively sharp deceleration by the vehicle 
in front of you.
 
 
– When a vehicle cuts in sharply between your 
vehicle and the one in front.
Some vehicles on the road may be 
poorly perceived or interpreted by the 
camera and/or the radar (e.g.
  truck), which 
can lead to an incorrect evaluation of 
distances and result in inappropriate 
acceleration or braking of the vehicle.
Pay particular attention:
–  When motorcycles are present and 
when there are vehicles staggered across the 
traffic lane.   
Page 118 of 228

Malfunction
In the event of a malfunction, dashes are 
displayed (orange) instead of the speed setting.
This warning lamp comes on, accompanied by a message and an 
audible signal, to confirm the malfunction.
Have it checked by a CITROËN dealer or a 
qualified workshop.
Lane positioning assist
For more information, refer to the 
General recommendations on the use 
of driving and manoeuvring aids .
 
 
The system identifies the limits of the traffic 
lane and steers the vehicle inside this lane to 
maintain it in the lateral position chosen by the 
driver.
To do this, the system uses a camera placed on 
the upper part of the windscreen.
This function is primarily suitable for driving on 
motorways and main roads.
Activation/Deactivation
Lane positioning assist is automatically activated, 
after selecting
  Highway Driver Assist   mode.
For more information on Highway Driver Assist, 
refer to the corresponding section.
The selection is confirmed by the display of the 
symbols on the instrument panel, representing 
the steering wheel and the side lines.
The colour of the symbols depends on the 
operating state of the system:
(grey)
One or more operating conditions is not met; the 
system is paused.
(green)
All operating conditions are met; the 
system is active.
(orange)
System malfunction.
If the driver no longer wishes to use the system 
for some time, they can deactivate it by pressing 
the ASSIST button again (confirmed by the 
disappearance of the Driving aids mini-view on 
the instrument panel).
The system status is saved when the  ignition is switched off.
Operating conditions
– Adaptive  cruise control active.
–  ESC system operational.
–
 
ASR system activated.
–
 
No trailer detected.
–
 
No 'space-saver' spare wheel in use.
–
 
V
 ehicle not subject to strong lateral g-forces.
–
 
Direction indicators off upon activation of the 
system.
Cruise control
The driver must hold the steering wheel properly.
When cruise control is activated, the symbols are 
displayed in green: with small steering inputs, 
the system steers the vehicle and keeps it in the 
position chosen by the driver in the traffic lane.    
Page 119 of 228
11 7
Driving
6This position is not necessarily the centre of the 
lane.
You can feel the steering wheel moving.
At any time, the driver can change the position of 
the vehicle by intervening on the steering wheel 
and maintaining the position until the system has 
taken it into account. If the chosen position is too 
off-centre, an automatic re-centering manoeuvre 
can occur. The system adjusts to the newly 
defined position.
Pausing/Suspending the 
system
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 that causes 
the Adaptive cruise control to pause will also 
cause the system to pause.
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 response from 
the driver.
If the function is suspended due to the 
prolonged release of the force holding 
the steering wheel, the system must be 
reactivated by pressing the  ASSIST button 
again.
Automatic pause
Pausing the system is accompanied by a specific 
audible signal. –
 
T
 riggering of the ESC.
–  
Insufficient lane detection. In this case, the 
Active lane departure warning system function 
can take over
 , and the system will reactivate 
itself once the operating conditions are met 
again.
Suspension by the driver
– Travelling outside the lane limits.
–  T oo tight a grip on the steering wheel or 
dynamic action on the steering wheel.
–
 
Action on the brake pedal (resulting in a pause 
until cruise control is reactivated) or accelerator 
pedal (suspension for as long as the pedal is 
depressed).
–
 
Pausing of 
 Adaptive cruise control.
–
 
Deactivation of the 
 ASR.
