For more information on Vehicle configuration
(MODE), refer to the corresponding section.
Warning and indicator
lamps
Displayed as symbols, the warning and indicator
lamps inform the driver of the occurrence of a
malfunction (warning lamps) or of the operating
status of a system (operation or deactivation
indicator lamps). Certain lamps light up in two
ways (fixed or flashing) and/or in several colours.
Associated warnings
The illumination of a lamp may be accompanied
by an audible signal and/or a message displayed
in a screen.
Relating the type of alert to the operating status
of the vehicle allows you to determine whether
the situation is normal or whether a fault has
occurred: refer to the description of each lamp
for further information.
When the ignition is switched on
Certain red or orange warning lamps come on
for a few seconds when the ignition is switched
on. These warning lamps should go off as soon
as the engine is started.

Indicators
Service information
For a few seconds after the ignition is switched
on, the spanner symbolising service information
comes on: the screen informs you when the next
service is due, in accordance with the servicing
schedule indicated in the manufacturer's service
schedule.


This information is determined in relation to the
distance travelled since the previous service.
Engine oil level
Depending on the engine, the engine oil level is
then displayed, on a scale of 1 (Min) to 5 (Max).
If no scale is displayed, the oil level is
insufficient; it is essential to top it up to prevent
engine damage.
For the measurement of this level to be valid, the
vehicle must be parked on horizontal ground,
with the engine having been off for more than 30
minutes.
If in doubt, check the oil level using the
dipstick.
For more information on Checking levels,
refer to the corresponding section.


After a few seconds, the display returns to its
standard functions.
Engine oil quality
This warning lamp flashes and, if your vehicle is equipped with this function, a
message is displayed at each start: the system

The doors can still be opened from the inside.
If one of the doors is open or not properly
closed, central locking does not work.
The control indicator lamp:
– comes on when the doors are locked and from
when the ignition is switched on,
– then flashes when the doors are locked when
stationary with the engine off.
This button is inoperative if the vehicle has been locked or deadlocked using an
exterior control (depending on equipment,
with the key or the remote control).
Driving with locked doors can make it
more difficult for emergency services to
access the vehicle in case of an emergency.
Loading area



► Press this button to lock / unlock the side
door and the rear doors from the cab.
The indicator lamp remains illuminated when
locking.

Ease of use and comfort
3If the air flow control is in
position 0 (system deactivated), thermal
comfort is no longer managed. A slight flow of
air can still be felt, due to the forward
movement of the vehicle.
Air distribution
The distribution of incoming air is directed by
turning the control towards:
the side vents and central vents,
the side vents, central vents and
footwells,
the footwells,
the windscreen, footwells and side
windows,
the windscreen and side windows.
Air intake/Air recirculation
The intake of exterior air prevents the formation
of mist on the windscreen and side windows.
Recirculating the interior air isolates the
passenger compartment from exterior odours
and fumes.
Used simultaneously with the air conditioning
switched on and the setting for the blown air
strength (from 1 to 4), recirculation makes it
possible to achieve the desired ambient air
comfort for both hot and cold settings. Return to exterior air intake as soon as possible
to avoid deterioration of the air quality and the
formation of mist.
► Put the control in this position to
activate interior air recirculation.
► Put the control in this position to
restore exterior air intake.

Switching on FULL AUTO:
► Press control 1. This turns on the system
functions, confirmed by the FULL AUTO display. This is the normal operating mode for the
automatic air conditioning system.
– Using the moving ring surrounding the AUTO
control, adjust the comfort temperature to be
reached according to a scale between: • HI (High up to ≈32) and
• LO (Low until ≈16).
The system manages the air distribution, flow
and intake to ensure the comfort equivalent
to the graduation displayed and sufficient air
recirculation in the passenger compartment.
Customisable AUTO mode
In AUTO mode, some settings can be changed:
distribution, air flow, air conditioning and air
intake/recirculation.
The display changes from FULL AUTO to
AUTO.
► To return to fully automatic operation, press
button 1 again. The control panel display
changes from AUTO to FULL AUTO.
If after manual adjustments, the system cannot
maintain the selected graduation, this will flash
and AUTO will then go out. Press control 1 to
return to the automatic settings.
Air conditioning off
► Press button 2 to switch off the air
conditioning functions. The snowflake goes out

Delayed starting of the
heating system
The start time can be programmed between 1
minute and 24 hours in advance.
You can memorise up to three different start
times, but only programme a single delayed
start.
To perform a daily start at a fixed time, reprogramme the memorised time each
day.
► Press button 3; the screen comes on.
The - -:- - symbol or the previous memorised
time and the corresponding preset number (1, 2
or 3) are displayed for 10 seconds.
To recall the other preset times, press button 3 several times before the end of
the 10 seconds.
Within 10 seconds, press one of the buttons 1 to
select the desired start time.
The memorisation is confirmed by the
disappearance of the start time, the display of
the preset number (1, 2 or 3) and the lighting of
the screen.
By default, preset times are already
memorised in the system (1 = 06:00, 2 =
16:00, 3 = 22:00). Any change cancels and
replaces the previous preset time.
If the battery is disconnected, the default
preset times will be restored.
Setting the comfort
temperature
► Turn control 1 to select a position between
blue (cold) and red (hot) so as to adjust the
temperature to your requirements.
The OFF control on the "Mono-zone" central control panel switches the
function off.
However, a back-up system will automatically
ventilate the rear circuit, even if the control is
in position 0, to avoid the formation of mist.
Air flow
► Set control 2 to the desired position to
increase or decrease the air flow.
Additional programmable heating
The additional programmable heating gradually
brings the engine to a good temperature to
facilitate its starting.
An built-in clock allows the time of its triggering
to be programmed. The passenger compartment
will warm up faster.
The warming-up of the passenger compartment, de-icing and demisting are
facilitated. The control panel for the programmable
additional heating is located next to the steering
wheel, below the MODE control panel.

Lighting and visibility
Lighting control stalk
In some weather conditions (e.g. low
temperature or humidity), the presence
of misting on the internal surface of the glass
of the headlamps and rear lamps is normal; it
disappears after the lamps have been on for a
few minutes.
Travelling abroad
If using your vehicle in a country that
drives on the other side of the road, the
headlamps must be adjusted to avoid
dazzling on-coming drivers.
Contact a CITROËN dealer or a qualified
workshop.

lamps switch off.
Programming
For countries where exterior lighting by day is
not a legal requirement, you can activate or
deactivate the function via the configuration
menu.
Automatic illumination of headlamps
If your vehicle is fitted with this function, the
dipped beam headlamps are switched on
automatically if the light is poor.
In fog or snow, the sunshine sensor may
detect sufficient light. In this case, the
lighting will not come on automatically. If
necessary, you must switch on the dipped
beam headlamps manually.
They are switched off when the light returns
to a sufficient level.
Do not cover the sunshine sensor at the top
centre of the windscreen.
You can adjust the sensitivity of the sunshine sensor.
