the occurrence of a fault in
one of the airbag or seat belt
pretensioner systems.
Maximum coolant temperature
If this comes on, it indicates
that the temperature in the
cooling system is too high.
Stop the vehicle as soon as
it is safe to do so.
Low fuel level When the tank is full, all the
bars are lit up.
If the fuel low warning lamp comes on
accompanied by an audible signal and
a message on the multifunction screen,
there are approximately 7 litres of fuel
remaining in the tank and 2 or 3 bars
fl ash in the instrument panel.
When the last bar goes out, there
are approximately 2 litres of fuel
remaining in the tank.
A control located on the panel to the
left of the steering wheel allows you
to open the fuel fl ap from inside the
vehicle.
Battery charge If this comes on, it indi-
cates the occurrence of a
fault in the battery charging
circuit (dirty or loose termi-
nals, slack or cut alternator
belt, ...). Door open
A door, the boot or the rear
screen is open:
- if the speed is below 6 mph (10 km/h), this warning lamp comes on continuously.

passengers’ seat belts are
unfastened. The lit up positions rep-
resent those whose seat belts are
not fastened/unfastened. Seat belts unfastened during the
journey:
- the point corresponding to the seat
position with seat belt unfastened
lights up between 0 and 20 km/h.
Above 20 km/h (approx. 12 mph),
it fl ashes accompanied by an audi-
ble signal for around 120 seconds.
The audible signal stops when the
ignition is switched off or if a door
is opened.
Depending on model, the front pas-
senger seat may be fi tted with a
presence sensor; the correspond-
ing warning lamp will only come on
if the seat is occupied and the seat
belt not fastened.

fl ashes accompanied by a mes-
sage on the multifunction screen
and an audible signal for around
120 seconds.

Air conditioning
To ensure that your system operates
correctly, it is recommended to have
it checked regularly.
Water arising from condensation
in the air conditioning drains away
through a hole provided for this pur-
pose. A pool of water may thus form
under the vehicle when stationary.
To keep the air conditioning com-
pressor well sealed, it is essential to
operate the air conditioning at least
once in every month.
Regardless of the season, the air
conditioning is useful, since it re-
moves humidity and condensation.
To be effective, the air conditioning
should only be used with the win-
dows closed.
If after a lengthy stop in bright sunlight
the interior temperature is excessive,
air the passenger compartment by
opening the windows for a few mo-
ments, then close them again.
The air conditioning operates by using
power from the engine. This results in
a slight increase in fuel consumption.
Dust filter/Odour filter
(active carbon)
There is a fi lter for excluding odours
and dust.
This fi lter has to be changed in ac-
cordance with the vehicle's servic-
ing schedule (see "Maintenance and
Warranty Guide").
Air circulation
Air vents on the fl oor underneath the
front seats provide enhanced heat-
ing for the rear seat positions; take
care not to obstruct them.
Air vents
The air vents to the face have grilles
and thumbwheels to adjust the air
fl ow and direction (up-down, right-
left).
The automatic regulation of the air
conditioning, inside the cabin, uses
a number of sensors (sunlight sen-
sor, outside temperature sensor...)
that relieve you of the need to make
frequent adjustments outside the
displayed temperature.
Be careful not to obstruct the sun-
light sensor, located on the dash-
board behind the instrument panel.

3. Adjustment of the air blower speed
The air blower operates only when
the engine is running (except when
the REST function is activated).
To adjust the fl ow of air, press on the
button:
to increase the air fl ow,
to decrease the air fl ow (this
button also has the REST
function).
The level of air fl ow is indicated on
the display by the progressive fi lling
of the ventilator blades.
If you place the air blower on posi-
tion 0 , the system is deactivated.
The air blower display will be empty,
with the indication OFF.

Function for retaining
ventilation with the engine
switched off

The REST function is availa-
ble when you switch on the ignition
and when you stop the engine.
This function allows you to retain
ventilation in the passenger com-
partment for a few minutes, even
with the engine stopped.
When you leave the vehicle, any
passengers present can still have
the benefi t of air circulation, even
though the engine is not running.
Engine stopped, ignition switched
on:
- The displays will light up, with the air blower shown empty as
long as the function is available.
- A press on the REST button acti- vates the function for a timing of
just a few minutes. Two blades of
the blower will fi ll to signify that
the function is active.
- It can be deactivated and reacti- vated during the timing.
- At the end of the timing, the dis- play will go off. This button does not activate the air
conditioning, only the air blowers. In
the REST function, the air fl ow and
distribution are controlled automati-
cally and you cannot modify them.

On stopping the engine:
- The displays remain lit up, the blower is shown empty and the
function can be activated for
30 seconds.
- A press on the REST button during the next 30 seconds ac-
tivates the function for a timing
of several minutes. The dura-
tion and availability of the func-
tion are variable according to the
state of charge of the battery (a
protection to guarantee engine
starting). Two blower blades fi ll
up to signify that the function is
active. It remains active, even af-
ter the doors have been locked,
until the end of the timing.
- A further press before the end of the timing defi nitively stops the
function. 4. Adjustment of the air
distribution

 Press on button 4 so that
the air fl ows scroll suc-
cessively on the display.
The air distribution you have chosen
is confi rmed by the lighting of the
corresponding warning lamps in the
display.
There are 7 possible adjustments.
5. Air recirculation
This button activates the recircula-
tion of air within the passenger com-
partment and also has an automatic
function.
Entry of air in automatic
mode (activated by default, in
automatic comfort regulation)
According to version, the automatic
mode makes use of an air quality
sensor. This analyses the air and
isolates the passenger compart-
ment from the exterior as soon as it
detects the presence of pollutants.
Then it automatically activates recir-
culation of cabin air.

C. fog lamps selection ring.
The fog lamps operate with the
sidelamps and the dipped and main
beam headlamps.
- 1 st turn forwards: rear foglamp on.
- 1 st turn rearwards: rear foglamp off. - 1 st turn forwards: front foglamps
on.
- 2 nd turn forwards: rear foglamps on.
- 1 st turn rearwards: rear foglamps off.
- 2 nd turn rearwards: front foglamps off.
Model with rear foglamp only
Model with front and rear
foglamps In good or rainy weather, both day
and night, the front foglamps and
the rear foglamp are prohibited. In
these situations, the power of their
beams may dazzle other drivers.
They should only be used in fog or
snow.
In these weather conditions, it is
your responsibility to switch on the
foglamps and dipped headlamps
manually as the brightness sensor
may detect suffi cient light.
Do not forget to switch off the front
foglamps and the rear foglamp when
they are no longer necessary.
Lighting on buzzer
The triggering of an audible signal
when a front door is opened warns
the driver that he has forgotten to
switch off his vehicle's lamps, with
the ignition off and in manual light-
ing mode.
In this case, switching off the lamps
stops the audible signal.
With the ignition off, if the dipped
headlamps remain on, they will
switch off automatically after thirty
minutes to prevent discharging of
the battery.

Linking with the automatic
"Guide-me-home" lighting
Association with the automatic light-
ing provides the "guide-me-home"
lighting with the following additional
options:
- selection of the lighting duration for 15, 30 or 60 seconds in the
vehicle parameters on the mul-
tifunction screen confi guration
menu (in the case of the mono-
chrome screen A, the duration is
fi xed),
- automatic activation of "guide- me-home" lighting when auto-
matic lighting is in operation.
Operating fault
In the event of a malfunction of
the brightness sensor, the lighting
comes on, a message appears on
the multifunction screen, accompa-
nied by an audible signal.
Consult a CITROËN dealer. In fog or snow, the brightness
sensor may detect suffi cient light.
Therefore, the lights will not come
on automatically.
Do not cover the brightness sen-
sor, linked with the rain sensor and
located in the centre of the wind-
screen behind the interior mirror;
the associated functions would no
longer be controlled.
