No vehicle detected:
the system operates as a
standard cruise control.
Detection of a
vehicle, at the limit of the range of the radar:
the system operates as a
standard cruise control.
"SPEED
ADJUSTED" Detection of a
vehicle that is too close or running at a speed lower than your vehicle's
cruise speed setting.
The system uses engine braking to slow your vehicle and then hold it at the speed of the
vehicle in front so as to obser ve the programmed inter-vehicle time.
The regulation range is limited to a
maximum difference of 19 mph (30 km/h) between the
cruise speed setting and the speed of the vehicle in front.
"SPEED
ADJUSTED" When the adjusted speed reaches the limit of regulation (speed setting – 19
mph
(30
km/h)), the adjusted speed flashes together with the speed setting to signal that
automatic deactivation of the system is imminent.
"Cruise control
paused". If the system exceeds the limit of speed adjustment that it can make and in the absence of
any reaction by the driver (operation of the direction indicator, change of lane, reduction in
the speed of the vehicle), the system is automatically paused.
The display of the deactivation message is accompanied by an audible signal.

Driving

158
Primarily designed for driving on main
roads and motor ways, this system only
works on moving vehicles, driving in the
same direction as your vehicle.
Principle of operation
The system 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 driving more slowly, the
system slows or even stops your vehicle, using
engine braking and the braking system (for
versions fitted with an automatic gearbox).
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 cruise control
allows your vehicle to temporarily approach
the vehicle in front to assist the overtaking
manoeuvre, though never exceeding the
programmed speed.
The brake lamps illuminate as soon as
the braking system is activated with
deceleration of the vehicle. This system is a
driving aid that cannot,
in any circumstances, replace the need to
obser ve speed limits and safety distances,
nor the need for vigilance on the part of
the driver.
Some vehicles present on the road may
not be properly seen or may be poorly
interpreted by the camera and/or radar
(e.g. a lorry), which may lead to a poor
assessment of the distances and lead to
the vehicle inappropriately accelerating or
braking.
The driver must be ready at all times
to retake control of their vehicle by
permanently holding both hands on the
steering wheel and keeping their feet near
the brake and accelerator pedals.

or 4
.
If the driver takes no action following this
immobilisation, the electric parking brake is
applied automatically after a

while (approx. five
minutes).
As a precaution, it is recommended
that you select a
cruise speed close to
the current speed of your vehicle, so
as to avoid any sudden acceleration or
deceleration of the vehicle.
Modification of the programmed

y pressing button 6 repeatedly, cycle
through the predefined settings.
The selection screen closes after a
few
seconds.
The modification is then accepted.
This setting remains in memory, whatever the
state of the system and when the ignition is
switched off.
The selection also applies to the stopping
distance (versions with EAT6
and
EAT8
automatic gearbox).
Three threshold settings are suggested for the
inter-vehicle distance:
-
"
Distant " (3 dashes),
- "
Normal " (2 dashes),
- "
Close " (1 dash).

Exceeding the programmed
setting
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.

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,

in a
workshop,
-

t

-

d
amaged front bumper (version with radar),
-

f
ollowing impact to the windscreen close to
the detection camera. The system is automatically deactivated
after the use of the "space-saver" type
spare wheel is detected, or if a
fault with
the lateral brake lamps is detected.
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.
After an impact, the function automatically
stops operating. Contact a
CITROËN
dealer or a
qualified workshop to have the
system checked.
If the front bumper is to be repainted or
retouched, contact a
CITROËN dealer
or a
qualified workshop. Certain types of
paint could inter fere with the operation of
the radar.
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 present in your traffic lane.
The current threshold can only be
modified via the touch screen's
Driving menu.
You can select one of three predefined
thresholds:
-
"Distant ",
-
"Normal ",
-
"Close ".
The last threshold selected is kept in memory
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, different levels of
alert can be triggered and displayed in the
instrument panel.
Clean the windscreen regularly,
particularly the area in front of the camera.
The internal sur face of the windscreen can
also become misted around the camera.
In humid and cold weather, demist the
windscreen regularly.
Do not allow snow to accumulate on the
bonnet or roof of the vehicle as this could
conceal the detection camera.
Clean the front bumper, especially around
the radar, removing mud, snow, etc.

If the driver wishes to maintain the
trajectory of the vehicle, they can prevent
the correction by keeping a firm grip on
the wheel (during an avoiding manoeuvre,
for example).
The correction is interrupted if the
direction indicators are operated.
While the direction indicators are on and for
a

few seconds after switching them off, the
system considers that any change of trajectory
is voluntary and no correction is triggered
during this period.
However, with the Blind Spot Detection system
activated, if the driver starts changing lanes
and another vehicle is detected in the vehicle's
blind spot, the system will correct the trajectory
of the vehicle even though the direction
indicators are on.
For more information on the Blind Spot
Detection , refer to the corresponding section. If the system detects that the driver is not
holding the wheel firmly enough during
an automatic correction of trajectory,
it interrupts the correction. An alert is
triggered to encourage the driver to take
back control of the vehicle.

associated alerts

the operation of the system or prevent it
working:
-

c
onditions of poor visibility (inadequate
street lighting, snowfall, rain, fog),
-

d
azzle (headlamps of an oncoming
vehicle, low sun, reflections on a
damp
road, leaving a
tunnel, alternating
shade and light),

mud) or multiple (roadworks, etc.),
-

r
unning close to the vehicle in front
(the lane markings may not be
detected),
-

r
oads that are narrow, winding, etc.
Risk of undesirable operation
The system is not intended for driving in the
following situations:
-
d
riving on a speed circuit,
-

d
riving with a trailer,
-

d
riving on a rolling stand,
-

d
riving on unstable sur faces.
In the event of a
fault with the system, you are
alerted by the illumination of these warning
lamps in the instrument panel, accompanied by
the display of a
message and an audible signal.
Have the system checked by a
CITROËN
dealer or a
qualified workshop.
