Dynamic cruise control with Stop function
The dynamic cruise control is a driving
aid that cannot in any circumstances
replace the observation of speed limits
and safe distances, nor the need for
vigilance on the part of the driver.
It is recommended that you always keep
your feet close to the pedals.
The driver must be ready to take back
control of their vehicle at any time,
using the brake or accelerator pedal as
appropriate.
This system provides two functions:
-

a

utomatic regulation of the speed of the
vehicle to a value programmed by the
driver,
-

a

utomatic adjustment of the distance
between your vehicle and the vehicle
ahead, even to the point of stopping your
vehicle completely.
It manages the acceleration and deceleration
of the vehicle by automatically acting on the
engine and the braking system.
To do this, the system has a radar, located in
the front bumper.
Principles
This system detects a vehicle running in front of
your vehicle, travelling in the same direction.
It automatically adapts the speed of your
vehicle to that of the vehicle in front, to maintain
a constant distance.
If the vehicle in front is running more slowly, the
system slows, or even stops your vehicle, using
engine braking and the braking system.
If the braking system is used to decelerate the
vehicle, the brake lamps come on.
If the vehicle in front accelerates or changes
lane, the cruise control progressively
accelerates your vehicle to return to the
programmed speed.
If the driver operates a direction indicator to
overtake a slower vehicle, the dynamic cruise
control allows your vehicle to temporarily
approach the vehicle in front to assist the
overtaking manoeuvre, though never exceeding
the programmed speed.

Switching on
The cruise control is switched on manually,
it requires a vehicle speed of between 18 and
112
mph (30 and 180 km/h).
An automatic gearbox must be in position D
or M . Other wise, the last setting made will be used
when switching on the system.
Switching off the ignition cancels any
programmed speed setting.
When the cruise control is operating,
Stop & Start is automatically
deactivated.
Pause
The dynamic cruise control can be paused
manually by:
-

a
ction by the driver:
●

o
n button 4 ,
●

o
n the brake pedal,
●

o
n the electric parking brake control,
●

w
hen changing from D to N with an
automatic gearbox.
-

o
r automatically, if operation of the ESC
system is triggered for reasons of safety.
Following braking of the vehicle
bringing it to a complete stop, the
system holds the vehicle stationary;
the cruise control is paused. The driver
should press the accelerator pedal to
move off, then reactivate the system
by exceeding 18
mph (30 km/h) and
pressing button
2, 3 or 4 .
If the driver takes no action following
this immobilisation, the electric parking
brake is applied automatically after a
few minutes.

Modification of the inter-vehicle distance setting
Three predefined inter-vehicle distance settings
are offered:
-
"
Distant" (3 dashes),
-

"
Normal" (2 dashes),
-

"
Close" (1 dash). Engine running and cruise control selected
(grey), you can modify the inter-vehicle
distance setting:
F

p
ress button 6 to display the selection
screen for inter-vehicle distance,
F
p
ress button 6 repeatedly to cycle through
the predefined settings.
The selection screen closes after a
few seconds.
The modification is then taken into account.
This setting remains in memory, whatever the
state of the system and when the ignition is
switched off.
It is possible to exceed the speed setting
temporarily by depressing the accelerator
pedal.
The cruise control no longer manages the
braking system during this period.
Simply release the accelerator pedal to return
to the programmed speed.
If the programmed speed setting is exceeded,
the display of the speed setting disappears
and a message "Cruise control suspended"
is displayed until the accelerator pedal is
released.

Operating fault
In the event of a fault with the cruise
control, you are alerted by the
illumination of this warning lamp
and the display of a message in the
instrument panel, accompanied by an
audible signal.
The cruise control operates by day and at night, in fog or moderate rainfall.
However, it is strongly recommended that you always keep a safe distance from vehicles
ahead, depending on the driving conditions, the weather and the road sur face.
Use the cruise control only where the driving conditions allow running at a constant speed
and at an adequate safe distance.
Do not use the cruise control in urban areas, heavy traffic, on winding or steep roads, on
slippery or flooded sur faces, in snow, if the front bumper is damaged or if the brake lamps
are faulty.
In certain circumstances, it may not be possible for the speed setting to be maintained or
even attained: loaded vehicle, ascending a steep hill, etc.
The system is not intended for the following situations:
-

t

he front end of the vehicle has been modified (addition of driving lamps, paint on the
bumper),
-

d

riving on a racing circuit,
-

r

unning on a rolling road,
-

u

se of snow chains, non-slip covers or studded tyres. Have the system checked by a CITROËN
dealer or a qualified workshop.
The operation of the radar, located in the front bumper, may be disturbed by accumulations
of grime (dust, mud...) or in certain weather conditions (snow, ice...).
The message "SYSTEM INACTIVE: Visibility reduced" is displayed to signal that the system
has been put into standby.
Clean the front bumper regularly.
When painting or touching up the paint on the front bumper, consult a CITROËN dealer or a
qualified workshop. Certain types of paint could hinder the operation of the radar. The use of mats not approved by CITROËN may inter fere with the operation of the cruise
control.
To avoid any risk of jamming the pedals:
-

e

nsure that mats are secured correctly,
-

n

ever fit one mat on top of another.

Collision Risk Alert and Active Safety Brake
This system includes three functions:
- C ollision Risk Alert (alert if there is a risk of
collision),
-

I
ntelligent emergency braking assistance,
-

A
ctive Safety Brake (automatic emergency
b r ak ing).
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.
Intelligent emergency braking assistance:
it completes the braking action taken by the
driver if this is inadequate.
Active Safety Brake: it intervenes following
the alert if the driver does not react quickly
enough and does not operate the vehicle's
brakes.
If the driver fails to act, the system
contributes towards avoiding a collision or
limiting its severity by reducing the speed
of your vehicle. 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.
This system does not avoid the need for
vigilance on the part of the driver.
The vehicle is fitted with a radar located in the front bumper and a camera at the top of the
windscreen.
Conditions for activation and operation
The system is active from about 4 mph (7 km/h)
and is deactivated below about 3 mph (5 km/h).
It takes account of:
-

v
ehicles running in the same direction or
stationary,
-

p
edestrians present in the traffic lane
(bicycles, motorcycles, animals and objects
on the road are not necessarily detected).
