Inter-vehicle distance
Using a radar with a range of about 100 metres,
located at the front of the vehicle, this system
detects a vehicle running in front of your
vehicle.
It automatically adapts the speed of your
vehicle to that of the vehicle in front.
If the vehicle in front is running more slowly,
the system progressively reduces the speed of
your vehicle using just engine braking (as if the
driver had pressed the " -" button).
If your vehicle is too close to, or approaching
too quickly the vehicle in front, the dynamic
cruise control is automatically deactivated.
The driver is then alerted by an audible signal,
accompanied by a message.
If the vehicle in front accelerates or changes
lane, the dynamic 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.

detected by the inter-vehicle distance
radar, if the speed selected is too far
above the speed of that vehicle, the
system is not activated and the alert
message "Activation not possible,
conditions unsuitable" is displayed until
driving conditions are safe to allow
activation of the system.
The inter-vehicle distance setting
is memorised when the ignition is
switched off.
Exceeding the programmed
speed
Simply release the accelerator pedal
to return to the programmed speed. It is possible to exceed the
programmed speed temporarily by
depressing the accelerator pedal. The dynamic cruise control can be paused
manually with the control, or automatically:
-
b

The following table describes the alerts and the messages displayed for the different driving situations.
The display of these alerts is not sequential.
Driving situations and associated alerts
SymbolAssociated message Comments
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 (within a limit of 20 mph (30 km/h))
and then hold it at the speed of the vehicle in front so as to observe the programmed inter-
vehicle time.
When automatically slowing down behind a vehicle, your true speed may be higher than
the "adjusted speed" displayed.
"SPEED ADJUSTED" When the adjusted speed reaches the limit of regulation (speed setting less than 20
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 possible by the system and in the
absence of any reaction by the driver (operation of the direction indicator, change of lane,
reduction of the speed of the vehicle), the system is automatically paused.
The display of the deactivation message is accompanied by an audible signal.
Driving
237
When the dynamic cruise control is
automatically paused, it can only be
reactivated when safe conditions are
restored. The message "Activation
not possible, conditions unsuitable"
is displayed while reactivation is not
possible.
When the conditions allow, it is
recommended that the function be
reactivated by pressing button 2 (SET+)
or 3 (SET-), which will make the current
speed of your vehicle the new cruise
speed setting, rather than by pressing
button 4 (on/pause) which reactivates
the cruise control using the old cruise
speed setting, which may be very
different from the current speed of your
vehicle.The speed regulation range is limited to a
maximum difference of 20 mph (30 km/h)
between the speed setting and the speed of
the vehicle in front.
Above this, the system goes into pause if the
safe distance becomes too small.
The dynamic cruise control uses only engine
braking to slow the vehicle. Consequently the
vehicle loses speed slowly, as when releasing
the accelerator pedal.
The system is paused automatically:
-
i
f the vehicle in front slows down too much
or too suddenly, and the driver does not
brake,
-
i
f a vehicle comes between your vehicle
and the vehicle in front,
-
i
f the system does not slow the vehicle
enough to continue to maintain a safe
distance, for example when descending a
steep hill.Limits of operation
As the radar's field of detection is quite narrow,
it is possible that the system may not detect:
-
v
ehicles of reduced width, such as
motorcycles, for example, -
v
ehicles not running in the middle of
the
lane,
-
v
ehicles entering a corner,
-
v
ehicles changing lane at the last moment.
The cruise control does not take
account of:
- s tationary vehicles,
-
v
ehicles driving in the opposite
direction.

In the event of a fault with the dynamic cruise
control, you are alerted by an audible signal
and display of the message message "Driving
aid functions fault".
Have the system checked by a CITROËN
dealer or a qualified workshop.
Operating faultThe dynamic cruise control operates
by day and at night, in fog or moderate
rainfall.When the cruise control is working, take
care if making a maintained press on
one of the cruise control programmed
speed modification buttons: this can
lead to a very quick change in the
speed of your vehicle.
Do not use the dynamic cruise control
on slippery sur faces or in heavy traffic.
When descending a steep hill, the
cruise control may not be able to
prevent the vehicle from exceeding the
programmed speed.
When ascending a steep hill or when
towing, it might not be possible to
achieve or maintain the programmed
speed.
The use of mats not approved by
CITROËN may inter fere with the
operation of the dynamic cruise control.
To avoid any risk of jamming the pedals:
-
e
nsure that mats are secured
c o r r e c t l y,
-
n
ever fit one mat on top of another.
It is recommended that you always keep
your feet close to the pedals.
If the difference between the
programmed speed setting and the
speed of the vehicle in front is too
great, the speed cannot be adjusted:
the cruise control is automatically
deactivated. The system does not act on the braking
system, but works only with engine
braking.
The regulation range is limited: there
will no longer be any adjustment of
speed if the difference between the
programmed speed setting and the
speed of the vehicle in front becomes
too high.
The dynamic cruise control cannot in any
circumstances replace the observation
of speed limits, nor the need for the
vigilance on the part of the driver.

Collision Risk Alert
Depending on the degree of risk of collision
detected by the system and the alert threshold
chosen, different levels of alert can be
triggered and displayed in the instrument panel
or the head-up display.
This level of alert is based on the inter-vehicle
time between your vehicle and the vehicle
ahead. Level 1
: visual alert only, warning you
that the vehicle ahead is very close.
A message on your vigilance is
displayed as you close on the vehicle
ahead.
This information also appears in the
head-up display.
For more information on the Head-up
display
, refer to the corresponding
section.
Driving
241
This level of alert is based on the time before
collision. It takes account of the vehicle
dynamics, the speed of your vehicle and the
one in front, the environmental conditions, the
operation of the vehicle (cornering, pedals
pressed, etc.) to trigger the alert at the best
moment.Level 2
: visual and audible alert,
warning you that a collision is
imminent.
A message indicating that you should
brake is displayed.
Where the speed of your vehicle is too
high approaching another vehicle, the
first level of alert may not be displayed:
the level 2 alert may be displayed
di r e c t l y.
Furthermore, the level 1 alert is never
displayed with the " Close" threshold.
Poor weather conditions (very heavy
rain, accumulation of snow in front of
the radar and the camera) may hinder
the operation of the system, with the
display of an operating fault message.
The system remains out of service until
the message disappears.
Programming the alert
thresholds
The thresholds for triggering an alert determine
how you wish to be warned of the presence of a
vehicle moving or stationary ahead of you, or a
pedestrian in your traffic lane.
You can select one of three thresholds:
-
" D
istant", to be warned early (cautious
driving).
-
" No
rmal".
-
" Cl
ose", to be warned later.
In the vehicle settings menu, activate/
deactivate "Collision risk alert and automatic
braking ".
With the touch screen With the audio system
In the "Personalisation-configuration "
menu, activate/deactivate " Auto. emergency
braking ".
Then modify the alert threshold.
Then modify the alert threshold.
Press on " Confirm" to save the change.
