Cruise control - "CRUISE"
System which automatically maintains the speed of the vehicle at the value programmed by the driver, without any action on the accelerator pedal.
The cruise control system cannot, in any circumstances, replace the need to observe speed limits, nor can it replace the need for vigilance on the part of the driver.
You are advised to keep your feet near the pedals at all times.
S
witching on the cruise control requires a
minimum vehicle speed of 25 mph (40 km/h).
As well as engagement of:
-

f

ourth gear or higher on a manual gearbox,
-

s

econd gear or higher in manual mode on
an automatic gearbox,
-

position
D on an automatic gearbox.
The system remains active after changing gear
on vehicles with a manual gearbox and Stop &
Start.
The cruise control is paused by pressing
button 4 or the brake pedal or on triggering of
the ESC system for safety reasons.
It is possible to exceed the programmed speed
temporarily by pressing the accelerator pedal.
To return to the programmed speed, simply
release the accelerator pedal until the
programmed cruise speed is reached again. 1.

In the event of the presence of a
vehicle detected by the radar, if the
speed selected is much higher than
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.

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 and then hold it at the speed of
the vehicle in front so as to maintain the programmed inter-vehicle time.
The regulation range is limited to a maximum difference of 20 mph (30 km/h)
between the speed setting and the speed of the vehicle ahead.
"SPEED ADJUSTED" When the adjusted speed reaches the control limit (speed setting - 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 situations and associated alerts
The table below describes the alerts and the messages displayed for the different driving situations.
The display of these alerts is not sequential.

164
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 system be
reactivated by pressing button 2 or 3,
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 system
using the old cruise speed setting,
which may be very different from the
current speed of your vehicle. 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 view is quite narrow, it is
possible that the system may not detect:
The cruise control does not take account of:
-
s

tationary vehicles,
-

v
ehicles driving in the opposite direction.
-

v
ehicles of reduced width, such as
motorcycles,
-

v
ehicles not running in the middle of the
lane,
-

v
ehicles entering a corner,
-

v
ehicles changing lane at the last moment.
The 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
a safe distance is not maintained.
Severe weather conditions (very heavy
rain, accumulations of snow in front
of the radar) can inter fere with the
operation of the system, resulting in
the display of the message "SYSTEM
INACTIVE: Visibility reduced". The
function remains unavailable until the
message disappears.
Driving

165
In the event of a fault with the dynamic cruise
control, you are alerted by an audible signal
and the display of the message "Driving aid
functions fault".
Have the system checked by a CITROËN
dealer or a qualified workshop.
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 attain
or maintain the programmed speed.
Operating fault
The operation of the radar, located in
the front bumper, may be disturbed by
accumulations of dirt (dust, mud, etc.)
or in certain weather conditions (snow,
ice, etc.).
The message "SYSTEM INACTIVE:
Visibility reduced" is displayed to signal
that the system has been put into
st a n dby.
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
c o r r e c t l y,
-

n

ever fit one mat on top of another.

When the cruise control is paused,
it can only be reactivated when all of
the safety conditions are met. The
message "Activation not possible,
conditions unsuitable" is displayed while
reactivation is not possible.
Wait until the speed of the vehicle
is close to the speed setting before
reactivating the system - by pressing
button 2 or 3 - in order to set your
current speed as the new speed setting.

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.
