Adjusting the Speed Limit
recognition and recommendation
setting
You do not have to switch the speed limiter on
in order to set the speed.
To modify the limit speed setting from the
current speed of the vehicle:
F
i
n steps of +/- 1 mph (km/h), make
successive short presses on button 2
or 3,
F

c
ontinuously, in steps of +/- 5 mph (km/h),
press and hold button 2
or 3.
To modify the limit speed setting using
memorised speeds and from the touch screen:
F

p
ress button 5 to display the memorised
speed settings,
F

p
ress the button for the desired speed
setting.
The selection screen closes after a
few
moments.
This setting becomes the new limit speed.
To modify the limit speed setting from the
speed suggested by the vehicle Speed Limit
recognition and recommendation:
F

t
he speed suggested is displayed in the
instrument panel,
F

m
ake a first press on button 5 ; a message
is displayed to confirm the memorisation
request,
F

p
ress button 5 again to save the suggested
speed.
The speed displays immediately in the
instrument panel as the new speed setting.
Temporarily exceeding the
programmed speed
F Press firmly on the accelerator pedal,
going beyond the point of resistance, to
exceed the programmed speed limit.
The speed limiter is deactivated temporarily
and the displayed programmed speed flashes.
An audible signal accompanies the flashing
of the programmed speed when exceeding
the speed is not due to an action by the driver
(steep hill, etc.).
As soon as the vehicle's speed returns to the
programmed value, the limiter operates again:
the display of the programmed speed becomes
steady again.
Switching off
F Turn wheel 1 to the 0 position. The display
of information related to the speed limiter
disappears.
Malfunction
Flashing of the dashes indicates a fault with the
sp eed limiter.
Have it checked by a
CITROËN dealer or
a


qualified workshop. On sharp acceleration, as when
descending a
steep hill, the speed limiter
will not be able to prevent the vehicle from
exceeding the programmed speed.
An audible signal accompanies the
flashing of the programmed speed when
exceeding the speed is not due to an
action by the driver.
The use of mats not approved by
CITROËN may inter fere with the operation
of the speed limiter.
To avoid any risk of jamming of the pedals:
-
e
nsure that the mat is positioned
c o r r e c t l y,
-
n
ever fit one mat on top of another.
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.
Driving

149
Operation of the cruise control requires
a vehicle speed of at least 25 mph (40 km/h).
As well as engagement:
-

o
f third gear or higher with a manual
gearbox,
-

o
f second gear or higher in manual mode
with an automatic gearbox,
-

o
f position D with an automatic gearbox.
The cruise control is paused manually by
pressing button 4
or pressing the brake pedal
or if the ESC system is invoked for safety
reasons.
It is possible to exceed the programmed speed
temporarily by depressing the accelerator
pedal.
To return to the programmed speed, simply
release the accelerator pedal until the
programmed cruise speed is reached again.
Switching off the ignition cancels any
programmed speed setting.
The cruise control system cannot, in any circumstances,
replace the need to obser ve speed limits, nor can it
replace the need for vigilance on the part of the driver.
It is recommended that you always keep your feet close
to the pedals.

The adaptive cruise control uses only
engine braking to slow the vehicle.
Consequently the vehicle loses speed
slowly, as when releasing the accelerator
pedal.
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 (19 mph (30 km/h)).
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.
General information
The adaptive cruise control is switched on
manually, it requires the speed of the vehicle
to be between 25
mph (40 km/h) and 93 mph
(150


km/h) and the engagement of:
-

t
hird gear or higher with a manual gearbox,
-

s
econd gear in manual mode with an
automatic gearbox,
-
position D with an automatic gearbox. If the cruise speed setting is above
93
mph (150 km/h), the adaptive cruise
control switches to standard cruise control
mode, without automatic regulation of the
inter-vehicle safety distance (a message
appears in the instrument panel).
The adaptive cruise control cannot in any
circumstances replace the obser vation of
speed limits, nor the need for the vigilance
on the part of the driver.
It is recommended that you always keep
your feet close to the pedals.
The adaptive cruise control can be paused
manually or automatically:
-
b
y pressing button 4
,
-
b
y pressing the brake pedal,
- i f the ESC system is activated, for safety
reasons,

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 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.

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.
