Driving
► 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 system is reinitialised.
Reinitialisation
The system must be reinitialised after any
adjustment to the pressure of one or more tyres,
and after changing one or more wheels.
Before reinitialising the system, make
sure that the pressures of the four tyres
are correct for the conditions of use of the
vehicle and conform to the values written on
the tyre pressure label.
Check the pressures of the four tyres before
performing the reinitialisation.
The system does not advise if a pressure is
incorrect at the time of reinitialisation.
The reinitialisation of the system is done with the
ignition on and the vehicle stationary:
– Via the vehicle configuration menu for vehicles fitted with a touch screen.– Via the button on the dashboard for vehicles without a touch screen.
With / Without audio system



► Hold this button down.Reinitialisation is confirmed by a high-pitched
audible signal.
A low-pitched audible signal indicates that the
reset operation has not been successful.
With touch screen
► In the menu Driving / Vehicle, select
the tab "Driving functions ", then "Reset
under-inflation detection ".
► Select "Ye s" to confirm.
The reinitialisation is confirmed by the display of
a message and an audible signal.
Malfunction
The illumination of these warning lamps
indicates a fault with the system.
A message appears, accompanied by an audible
signal.
In this case, under-inflation monitoring of the
tyres is no longer assured.
Have the system checked by a CITROËN dealer
or a qualified workshop.
Driving and manoeuvring
aids - General
recommendations
Driving and manoeuvring aids cannot, in
any circumstances, replace the need for
vigilance on the part of the driver.
The driver must comply with the Highway
Code, must remain in control of the vehicle in
all circumstances and must be able to retake
control of it at all times. The driver must adapt
the speed to climactic conditions, traffic and
the state of the road.
It is the driver's responsibility to constantly
check the traffic, to assess the relative
distances and speeds of other vehicles and to
anticipate their movements before indicating
and changing lane.
The systems cannot exceed the limits of the
laws of physics.
Driving aids
You should hold the steering wheel
with both hands, always use the interior and
exterior rear view mirrors, always keep the
feet close to the pedals and take a break
every two hours.
Manoeuvring aids
The driver must always check the
surroundings of the vehicle before and during
the whole manoeuvre, in particular using the mirrors.


Driving aids camera
This camera and its associated functions
may be impaired or not work if the windscreen
area in front of the camera is dirty, misty,
frosty, covered with snow, damaged or
masked by a sticker.
In humid and cold weather, demist the
windscreen regularly.
Poor visibility (inadequate street lighting,
heavy rain, thick fog, snowfall), dazzle
(headlamps of an oncoming vehicle, low sun,
reflections on a damp road, leaving a tunnel,
alternating shade and light) can also impair
detection performance.
In the event of a windscreen replacement,
contact a CITROËN dealer or a qualified
workshop to recalibrate the camera;
otherwise, the operation of the associated
driving aids may be disrupted.
Other cameras

according to the information given by the system.
Activation / Deactivation
The system is activated or deactivated via the
vehicle configuration menu.
Without audio system
► In the "DRIVE ASSIST" menu on the
instrument panel display, activate/deactivate
"ADVISED SPEED" (Speed limit recognition).
With audio system
► In the "Personalisation-
configuration " menu, activate/deactivate
"Speed recommendation".
With touch screen
► In the Driving / Vehicle menu, select
the "Vehicle settings" tab, then
"Security" and activate/deactivate " Displaying
of the recommended speed.".
Information display
With an LCD text instrument panel, the speed
limit recognition information is displayed after the
trip computer information.
To display it:


► Press the button located on the end of the wiper control stalk .

► Or, depending on equipment, press the knob located on the steering wheel.
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,– when towing,– driving with a space-saver type spare wheel or snow chains fitted,– Tyre repaired using the temporary puncture repair kit,– young drivers.It is possible for the system to 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, do not comply with the standard, are damaged or distorted,– obsolete or incorrect maps.
Memorising the speed
setting

In addition to Speed Limit Recognition and
Recommendation, the driver can select the
speed displayed as a speed setting for the speed
limiter or cruise control using the speed limiter or
cruise control memorisation button.
For more information on the Speed
limiter or Cruise control, refer to the
corresponding sections.

With touch screen
► In the Driving / Vehicle menu, select
the "Vehicle settings" tab, then
"Security" and activate/deactivate " Fatigue
Detection System ".
Coffee Break Alert
The system triggers an alert as soon as it detects that the driver has not taken a
break after two hours of driving at a speed above
40 mph (65 km/h).This alert is issued via the display of a message
encouraging the driver to take a break,
accompanied by an audible signal.
If the driver does not follow this advice, the alert
is repeated hourly until the vehicle is stopped.
The system resets itself if one of the following
conditions is met:
– With the engine running, the vehicle has been stationary for more than 15 minutes.– The ignition has been switched off for a few minutes.– The driver's seat belt is unfastened and their
door is opened.
As soon as the speed of the vehicle drops below 40 mph (65 km/h), the system goes into standby.
The driving time is counted again once the
speed is above 40 mph (65 km/h).
Driver Attention Warning
Depending on version, the "Coffee Break Alert"
system is combined with the "Driver Attention
Warning" system.


Using a camera placed at the top of the windscreen, the system assesses the
driver's level of vigilance, fatigue or distraction by
identifying variations in trajectory compared to
the lane markings.
This system is particularly suited to fast roads
(speed higher than 40 mph (65 km/h)).At a first-level alert, the driver is warned by the
“Take care! ” message, accompanied by an
audible signal.
After three first-level alerts, the system triggers
a further alert with the message " Dangerous
driving: take a break", accompanied by a more
pronounced audible signal.
In certain driving conditions (poor road
surface or strong winds), the system may
give alerts independent of the driver's level of
vigilance.
The following situations may interfere with the operation of the system or
prevent it from working:
– lane markings absent, worn, hidden (snow , mud) or multiple (roadworks);– close to the vehicle ahead (lane markings not detected);– roads that are narrow, winding, etc.
Lane Departure Warning
System
Refer to the General recommendations on the
use of driving and manoeuvring aids .
This system, using a camera which recognises
solid or broken lines, detects the involuntary
crossing of longitudinal traffic lane markings on
the ground.
If the driver's attention drops and the speed
is higher than 37 mph (60 km/h), the system triggers a warning if there is an unexpected
change of direction.
This system is particularly useful on motorways
and main roads.


Deactivation / Activation
The system is activated every time the ignition
is switched on.


OFF

► To deactivate the system, press this button.Deactivation is signalled by the lighting
of the indicator lamp on the button and
this warning lamp on the instrument panel.
Reactivation is carried out via another press; the
indicator lamp on the button and the warning
lamp go out.
Detection
If an unexpected change of direction is detected, this warning lamp flashes in the
instrument panel accompanied by an audible
signal.
No warning is transmitted while the direction
indicator is activated and for approximately 20

the (+) terminal.
Quick-release terminal clamp
Disconnecting the (+) terminal

► Raise the lever A fully to release the clamp
B.
► Remove the clamp B by lifting it off.
Reconnecting the (+) terminal


► Raise the lever A fully.► Refit the open clamp B on the (+) terminal.► Push the clamp B fully down.► Lower the lever A to lock the clamp B.
Do not force the lever as locking will not
be possible if the clamp is not positioned
correctly; start the procedure again.
Following reconnection of the battery
After reconnecting the battery, turn on the
ignition and wait 1 minute before starting the
engine, in order to enable the electronic systems
to initialise.
For right-hand drive vehicles, when the
total distance recorder has reached 37
miles (60 km), it is necessary to wait approx.
15 minutes before starting the engine.
However, if minor problems persist following
this operation, contact a CITROËN dealer or a
qualified workshop.
Referring to the corresponding section, you must
yourself reinitialise or reset certain systems,
such as:
– the key with remote control or electronic key (depending on version),– the sunroof and its electric blind,– the electric windows,– the date and time,– the preset radio stations.
The Stop & Start system may not be
operational during the trip following the
first engine start.
In this case, the system will only be
available again after a continuous period of
immobilisation of the vehicle, a period which
depends on the exterior temperature and the
state of charge of the battery (up to about 8
hours).
