Driving
The inflation pressures defined for the vehicle can be found on the tyre pressure
label.
Tyre pressures should be checked when the
tyres are "cold" (vehicle stopped for 1 hour or
after a journey of less than 6 miles (10 km) at
moderate speeds). Otherwise, add 0.3 bar to
the pressures shown on the label.
For more information on Identification
markings, including the tyre pressure label,
refer to the corresponding section.
The tyre pressure measurement unit can be configured with the MODE button: in
the "Tyre pressure measurement” menu, select
"psi/bar/kPa".
For more information on Vehicle configuration
(MODE), refer to the corresponding section.
Under-inflation alert
This is signalled by the fixed illumination of this warning lamp, accompanied by an
audible signal and, depending on equipment, the
display of a message.
In the event of an anomaly noted on just one of
the tyres, depending on equipment, the symbol
or the message displayed identifies it.
► Reduce speed immediately, avoid excessive
steering movements and avoid sudden braking.
► Stop 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 rely on just a visual check.
► Using a compressor, such as the one in
the temporary puncture repair kit, check the
pressures of the four tyres when cold.
► If it is not possible to make this check
immediately, drive carefully at reduced speed.
► In the event of a puncture, use the
temporary puncture repair kit or the spare wheel
(depending on equipment).
The alert is kept active until the tyre/tyres concerned is/are reinflated, repaired or
replaced.
Malfunction
The flashing and then fixed illumination of this warning lamp, accompanied by the
illumination of the service warning lamp, and
depending on equipment, the display of a
message, indicates a fault with the system.
In this case, the tyre pressures are no longer
monitored.
This alert is also displayed if at least one wheel is not equipped with a sensor.
Contact a CITROËN dealer or a qualified
workshop to have the system checked or,
following a puncture, to have the original wheel,
equipped with a sensor, refitted.
Pneumatic suspension

If the vehicle is equipped with pneumatic
suspension, it is possible to change the height
of the rear sill, in order to facilitate loading or
unloading.




There is a normal sill level, as well as 3 higher
levels (from +1 to +3) and 3 lower levels (from
-1 to -3). Each level reached is displayed on the
instrument panel display screen.
Loading sill height manual
correction
Adjusting the platform sill up or down
► A quick press on one of the controls selects
the upper or lower level. Each press (diode lit)
increases or decreases by one level.
A long press on one of the controls selects the
maximum corresponding level (-3 or +3).
Returning to the normal sill height
► Press the same number of times in the
opposite direction of the displayed position.
Deactivation/Reactivation
► Press and hold both controls simultaneously
to deactivate/reactivate the system.
Deactivation is confirmed by the lighting of the
control LEDs.
Beyond a speed of 3 mph (5 km/h), the
system reactivates automatically.
Loading sill height
automatic correction
Beyond a speed of 12 mph (20 km/h), the
system automatically restores the rear sill height
to its normal level.

Driving
simultaneously in the two dedicated areas of the
instrument panel.
If an additional road sign is detected, such
as a reduced speed limit for wet road sign, it
is displayed in an empty window below the
corresponding sign.
Additional signs are filtered as follows:
– Signs for snow or ice only appear if the
outside temperature is below 3°C.
– Signs for snow, rain or fog are only displayed
if the wipers are activated while the outside
temperature is below 3°C.
– Signs concerning heavy goods vehicles are
not displayed if they concern a vehicle weighing
less than 4 tonnes.
– Signs concerning farm equipment are not
displayed.
Signs such as no overtaking go out after about
40 seconds on the instrument panel.
Activation/Deactivation
This function can be set using the MODE button: in the “Traffic Sign” menu, select
“ON” or “OFF”.
For more information on Vehicle
configuration (MODE) , refer to the
corresponding section.
Operating limits
The system does not take account of reduced
speed limits, especially those imposed in the
following cases:
– Poor weather (rain, snow).
– Atmospheric pollution.
– Towing.
– Driving with a space-saver type spare wheel
or snow chains fitted.
– Driving with a non-standard suspension kit.
– Tyre repaired using the temporary puncture
repair kit.
– Young drivers.
The system may not display the speed limit if it
does not detect a speed limit sign within a preset
period and in the following situations:
– Road signs that are obstructed, non-standard,
damaged or bent.
– Obsolete or incorrect maps.
– Road incline causing the sign to be out of the
camera field of vision (on a slope, for example).
– Change in the vehicle load that causes the
camera to tilt significantly (system operation may
temporarily be suspended to enable camera
self-calibration).
Speed limiter
Refer to the General recommendations on the
use of driving and manoeuvring aids .
System which prevents the vehicle
from exceeding the speed
programmed by the driver. The speed is selected when the vehicle is
stationary with the engine running or while
driving with at least 2
nd gear engaged.
The minimum speed to be programmed is 19
mph (30 km/h).
The vehicle responds to the driver's foot
pressure on the accelerator until resistance is felt
in the pedal, which signifies that the vehicle has
reached the programmed speed.
However, depressing the pedal beyond this point
of resistance to the floor allows you to exceed
the programmed speed. To resume use of the
speed limiter, gradually release the pressure
on the accelerator pedal and return below the
programmed speed.


1. Selection of the speed limiter function
2. Activation / deactivation of the function
3. Programming a speed
The selection status of the function and the
programmed speed are visible in the instrument
panel display screen.
Selecting the function
► Turn ring 1 all the way down. The speed
limiter is selected, but is not yet active.


The display indicates OFF and the last
programmed speed.
Programming a speed
A speed can be programmed without activating
the speed limiter but with the engine running.
To memorise a speed higher than the previous
one:
► Move the control upwards (+).
A short press increases the setting by 1 mph
(km/h).
Pressing and holding increases the setting in
steps of 5 mph (km/h).
To memorise a speed lower than the previous
one:
► Move the control downwards (-).
A short press decreases the setting by 1 mph
(km/h).
Pressing and holding decreases the setting in
steps of 5 mph (km/h).
Activation/Deactivation
► Press button 2 to activate the speed limiter.

In the event of a breakdown
8► Disconnect hose I and directly connect it
to the tyre valve; the cartridge will thereby be
connected to the compressor and the sealant will
not be injected.
If the tyre needs to be deflated, connect hose
I to the tyre valve and press the yellow button
located in the centre of the compressor switch.
Replacing the cartridge

To replace the sealant cartridge, proceed as
follows:
► Disconnect the hose I.
► Turn the cartridge to be replaced anti-
clockwise and lift it.
► Insert the new cartridge and turn it clockwise,
► Reconnect the hose I and connect pipe B to
its location.
The cartridge contains ethylene glycol, which is harmful if swallowed and irritates
the eyes.
It must be kept out of the reach of children.
After use, do not discard the cartridge in standard waste, take it to a
CITROËN dealer or an authorised waste
disposal site.
Spare wheel
Parking
► Park the vehicle where it does not block
traffic: the ground must be level, stable and
non-slippery.
► If the road is sloping or damaged, place an
object under the wheels to act as a chock.
► With a manual gearbox, engage first gear
then switch off the ignition to block the wheels.
► Apply the parking brake and check that the
warning lamp is on in the instrument panel.
► The passengers must get out of the vehicle
and wait where they are safe.
► Put on the high visibility vest and signal that
the vehicle is immobile by using the devices
envisaged by the legislation in force in the
country where you are driving (warning triangle,
hazard warning lamps, etc.).
► Equip yourself with the tools.
Special feature with pneumatic
suspension
