Driving
When the driver must suspend the cruise
control system:
Malfunction
Pay particular attention:
-
When motorcycles are present and
when there are vehicles staggered
onto the traffic lane.
If the cruise control
malfunctions, dashes are
displayed instead of the
cruise control speed setting.
-
When entering a tunnel or crossing
a bridge.
If this warning lamp comes
on, accompanied by an
alert message and an
audible signal, this confirms
a malfunction.
If one of these malfunctions occurs, do not
use the system:
-
-
Vehicles in a tight bend.
When approaching a roundabout.
-
Following an impact on the windscreen
close to the camera or on the front
bumper (versions with radar).
Brake lamps not working.
Have the system checked by a CITROËN
dealer or a qualified workshop.
-
Active Lane Keeping

Cases where the driver is urged to take
back control immediately:
-
Use of the "space-saver" type spare
wheel (depending on version).
Front end of the vehicle modified
(addition of long-range headlamps,
painting of the front bumper).
Excessively sharp deceleration of the
vehicle in front of you.
-
Refer to the General recommendations on

to keep it in the lateral position chosen by the
driver.

When a vehicle cuts in sharply between
your vehicle and the one in front.

Driving
This function is primarily suitable for driving on
motorways and main roads.
(orange colour)
The system has a fault.
Activation/Deactivation
The state of the system stays in the
memory when the ignition is switched off.
Conditions for operation
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.
-
-
The adaptive cruise control must be active.
The vehicle must be travelling in a traffic
lane clearly delimited by lines on both sides.
The ESC system must be operating.
The ASR/DSC systems must not be
deactivated.
-
-
-
-
No trailer detected.
A spare wheel of the "space-saver" type
must not be in use.
The vehicle must not be subject to strong
lateral accelerations.
The direction indicators must not be
activated.
Cruise control
The driver must hold the steering wheel
properly.
-
-
F
With the adaptive cruise control activated, press this
button.
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 action is confirmed by:
-
-
Illumination of the indicator lamp in the button in green.
Display of the following symbol in the instrument panel.
The colour of the symbol depends on the
operating state of the system:
The driver can feel movements in the steering
wheel.
This position is not necessarily the centre of
the lane.
(grey colour)
At least one of the operating
conditions is not met, the system is
paused.
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.
(green colour)
All operating conditions are met, the
system is active.

Driving
Automatic pausing:
Pausing/Suspension of the
system
Driving situations and
associated alerts
-
-
Triggering of the ESC.
Prolonged 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.
The tables below describe the displays
associated with the main driving situations. The
display of these alerts is not sequential.
The driver must intervene as soon as
they believe that the traffic conditions or
the state of the road surface 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.
On action by the driver: suspension
-
-
-
Activation of the direction indicators.
Travelling outside the lane limits.
Too tight a grip on the steering wheel or
dynamic action on the steering wheel.
Action on the brake pedal (pausing until the
cruise control is reactivated) or accelerator
pedal (suspension for as long as the pedal
is pressed).
-
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.
-
-
Pausing the cruise control.
Deactivation of the DSC/ASR systems.

After suspension due to the prolonged
release of the force holding the steering
wheel, you must reactivate the function by
pressing the button again.
