Safety
5Dynamic stability control
(DSC)
Switching on
The DSC system is activated automatically every
time the vehicle is started.
It comes into operation in the event of a grip or
trajectory problem.
This is indicated by the flashing of this warning lamp on the instrument panel.
Deactivation
This system cannot be deactivated by the driver.
Malfunction
The lighting of this warning lamp, accompanied by an audible signal and
confirmed by a message on the instrument panel
display, indicates a malfunction of the DSC
system.
Have the system checked by a CITROËN dealer
or a qualified workshop.
Anti-slip regulation (ASR)
Deactivation / Reactivation
The ASR system is activated automatically every
time the vehicle is started.
In exceptional conditions (starting a vehicle
which is bogged down, stuck in snow, on soft
ground, etc.), it may be advisable to deactivate
the ASR system, so that the wheels can turn
freely and regain grip.
Reactivate the system as soon as the level of
grip permits.



ASR

► Press this button to deactivate / reactivate the
function.
The illumination of the button indicator lamp,
accompanied by a message on the instrument
panel display screen, indicates that the ASR
system is deactivated.
The ASR system is automatically reactivated
every time the ignition is switched off
Malfunction
The lighting of this warning lamp, accompanied by an audible signal and
confirmed by a message on the instrument panel
display, indicates a malfunction of the ASR
system.
Have the system checked by a CITROËN dealer
or a qualified workshop.
ASR / DSC
These systems offer increased safety in
normal driving, but they should not encourage
the driver to take extra risks or drive at high
speed.
It is in conditions of reduced grip (rain, snow,
ice) that the risk of loss of grip increases. It
is therefore important for your safety to keep
these systems activated in all conditions, and
particularly in difficult conditions.
The correct operation of these systems
depends on observation of the manufacturer's
recommendations regarding as much
the wheels (tyres and rims), braking and
electronic components as the assembly and
repair procedures used by CITROËN dealers.
To benefit in full from the effectiveness
of these systems in wintry conditions,
the vehicle must be fitted with four snow
tyres, allowing the vehicle to retain neutral
behaviour on the road.
Intelligent Traction Control
Traction assistance system on roads with low
grip (snow, ice, mud, etc.).
This system makes it possible to detect the
situations of precarious grip which can make the
starting and the progress of the vehicle difficult.
In these situations, the Intelligent Traction
Control system overrides the ASR system by
transferring the driving force to the wheel with
the greatest contact with the ground to optimise
traction and trajectory tracking.

71
Driving
6This system (also called HHC - Hill Hold
Control), integrated with the dynamic stability
control system, is activated in the following
conditions:
– the vehicle must be stationary, engine running,
foot on the brake,
– the gradient of the road must be steeper than
5%,
– uphill, the gearbox must be in neutral or in a
gear other than reverse,
– downhill, reverse gear must be engaged.
The hill start assist system is a driving
aid. It is not an automatic vehicle parking
function or an automatic parking brake.
Operation

With the brake pedal and clutch pedal pressed,
from the time you release the brake pedal,
without using the parking brake, you have
approximately 2 seconds to move off before the
vehicle starts to roll back.
During the moving off phase, the function is
deactivated automatically, gradually releasing
the braking pressure. During this phase, you
may hear the typical mechanical brake release
noise, signalling the imminent movement of the
vehicle.
Do not leave the vehicle while it is being
held temporarily by hill start assist.
If you need to get out of the vehicle with
the engine running, apply the parking brake
manually then ensure that the parking brake
indicator lamp is on.
Hill start assist is deactivated in the following
situations:
– when the clutch pedal is released,
– when the parking brake is applied,
– when the engine is switched off,
– if the engine stalls.
Malfunction
If a malfunction of the system occurs, this
warning lamp lights up, accompanied by
an audible signal and confirmed by a message
on the display. Have the system checked by a
CITROËN dealer or a qualified workshop.
Tyre under-inflation detection
System which automatically checks the
pressures of the tyres while driving.
The system continuously monitors the pressures
of the four tyres, as soon as the vehicle is
moving.
A pressure sensor is located in the valve of each
tyre (except the spare wheel).
The system triggers an alert as soon as it
detects a drop in the inflation pressure of one or
more tyres.
The under-inflation detection system does not replace the need for vigilance
on the part of the driver.
This system does not avoid the need to
regularly check the tyre pressures (including
the spare wheel) as well as before a long
journey.
Driving with under-inflated tyres, particularly
in adverse conditions (heavy load, high
speed, long journey):
– worsens road-holding,
– lengthens braking distances,
– causes premature wear of the tyres,
– increases fuel consumption.

72
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.

In the event of a breakdown
► Connect the red cable to metallic terminal A,
then to the (+) terminal of backup battery B.
► Connect one end of the green or black cable
to the negative (-) terminal of backup battery B.
► Connect the other end of the green or black
cable to earth point C of your vehicle.
► Operate the starter, let the engine run.
► Wait for the engine to return to idle and
disconnect the cables.
Charging the battery using a
battery charger
► Access the battery, located in the left-hand
front floor.
► Disconnect the battery.
► Follow the instructions for use provided by
the manufacturer of the charger.
► Reconnect starting with the (-) terminal.
► Check the cleanliness of the terminals. If they
are covered with sulphate (whitish or greenish
deposit), remove and clean them.
The charging operation must be carried out in a well-ventilated area and away
from naked flames and any sources of sparks
so as to avoid the risk of explosion or fire.
Do not try to recharge a frozen battery: it
must first be thawed to avoid the risk of
explosion. If it has frozen, before charging it,
have the battery checked by a specialist who
will check that the interior components have
not been damaged and that the container is
not cracked, which would involve a risk of
leakage of toxic and corrosive acid.
Perform a slow charge at low amperage for
about 24 hours maximum to avoid damaging
the battery.
The presence of this label, in particular with the Stop & Start system, indicates
the use of a 12 V lead-acid battery with
special technology and specification; the
involvement of a CITROËN dealer or a
qualified workshop is essential when
replacing or disconnecting the battery.
After refitting the battery at a CITROËN dealer or a qualified workshop, the Stop
& Start system will only be active after a
continuous period of immobilisation of the
vehicle, a period which depends on the
climatic conditions and the state of charge of
the battery (up to about 8 hours).
