Checking tyre pressures
This check should be done when the tyres
are "cold" (vehicle stopped for 1 hour or
after a
journey of less than 6 miles (10 km)
at moderate speeds).
Other wise, add 0.3
bar (30 kPa) to the
values indicated on the label.
Under-inflation alert
This is indicated by continuous
illumination of this warning lamp,
an audible signal and, depending
on equipment, the display of
a


message.
F

R

educe speed immediately, avoid excessive
steering movements and sudden braking.
F

S

top the vehicle as soon as it is safe to do
so.
The loss of pressure detected does not
always cause visible bulging of the tyre.
Do not satisfy yourself with just a
visual
check. F

I
f it is not possible to make this check
immediately, drive carefully at reduced
speed.
or
F
I
n case of a puncture, use the temporary
puncture repair kit or the spare wheel
(depending on equipment).
The alert is kept active until the system is
reinitialised.Reinitialisation
The system must be reinitialised after any
adjustment to the pressures of one or more
tyres, and after changing one or more wheels.
Before reinitialising the system, ensure
that the pressures of the four tyres
are correct for the conditions of use
of the vehicle and conform to the
recommendations on the tyre pressure
label.
The under-inflation alert can only be relied
on if the reinitialisation of the system has
been done with the pressures in the four
tyres correctly adjusted.
The under-inflation detection system
does not give a
warning if a pressure is
incorrect at the time of reinitialisation. Snow chains
The system does not have to be
reinitialised after fitting or removing snow
chains.
Reinitialisation of the system is done on the
touch screen, with the ignition on and the
vehicle stationary.
F

C
onfirm the instruction by pressing "
Ye s",
an audible signal and a message confirm
the reinitialisation.
The new pressure parameters saved are
treated as reference values by the system.
Malfunction
F If you have a compressor, such as the one
in the temporary puncture repair kit, check
the pressures of the four tyres when cold. In this case, under-inflation monitoring of the
tyres is no longer provided.
Have the system checked by a
CITROËN
dealer or a
qualified workshop.
The flashing and then fixed illumination of the
under-inflation warning lamp accompanied
by illumination of the Ser vice warning lamp
indicates a
fault with the system.
A message appears, accompanied by an

Memorising speeds
This function allows speeds to be saved, which
can then be offered to set the two systems: the
speed limiter (to limit the speed of the vehicle)
or the cruise control (for a vehicle cruising
speed).
You can memorise up to six speed settings
for each of the two systems. By default, some
speed settings are already memorised.
Memorisation
This function can be accessed in the Driving
menu of the touch screen.

As a safety measure, the driver must carry
out these operations when stationary.
After carrying out any work on the system,
the pressure of the four tyres must be
checked and the system reinitialised.
F
S

memorise new speed settings.
Speed Limit recognition
and recommendation
This system allows the speed limit detected by
the camera to be displayed in the instrument
panel.
The system also processes speed limit
information from the navigation system
mapping.
You should update your navigation
mapping regularly in order to receive
accurate speed limit information from the
system.
Specific speed limits, such as those for heavy
goods vehicles, are not displayed.
The display of the speed limit in the instrument
panel is updated as you pass a
speed limit sign
intended for cars (light vehicles).
Driving

145
The speed limit units (mph or km/h)
depend on the country you are driving in.
This should be taken into account in order
to obser ve the speed limit.
For the system to operate correctly when
you change country, the units for speed in
the instrument panel must be those for the
country you are driving in.
The automatic reading of road signs is
a driving assistance system and does not
always display speed limits correctly.
The speed limit signs present on the road
always take priority over the display by the
system.
The system cannot in any circumstances
replace the need for vigilance on the part
of the driver.
The driver must observe the driving
regulations and must adapt the speed of
the vehicle to suit the weather and traffic.
The system may not display the speed
limit if it does not detect a
speed limit sign
within a
preset period.
The system is designed to detect signs
that conform to the Vienna Convention on
road signs. To maintain correct operation of the
system: regularly clean 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.
Activation/Deactivation
Activation and deactivation of the system is
done in the touch screen's Driving
menu.
Select the " Vehicle settings " tab, then
" Security "/ "Safety " and "Recommended
speed display ".
Displays in the instrument panel
1.Detected speed limit indication.
or
2. Indication of the end of the speed limit. The system is active but is not detecting speed
limit information.
On detection of speed limit information, the
system displays the value.
Operating limits
The legislation on speed limits is specific to
each country.
The system does not take account of reduced
speed limits in the following cases:
-

p
oor weather (rain, snow),
-
a

tmospheric pollution,
-

Speed limiter "LIMIT"
System which prevents the
vehicle from exceeding the speed
programmed by the driver.
Once the programmed speed limit is reached,
additional pressure on the accelerator pedal
has no effect.
Operation of the speed limiter requires
a

programmed speed of at least 19 mph
(30


km/h).
The speed limiter is paused using the control.
The programmed speed can be exceeded
temporarily by pressing the accelerator firmly
beyond the point of resistance.
To return to the programmed speed, simply
release the accelerator pedal until the set
speed limit has been reached again.
The programmed speed remains in the system
memory when the ignition is switched off.
The speed limiter 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.

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
