Trip computer, a few definitions
When the range falls below 20 miles (30 km),
dashes are displayed. After filling with at least
5 litres of fuel, the range is recalculated and is
displayed when it exceeds 60 miles (100 km).
Range
(miles or km)
The distance which can still be
travelled with the fuel remaining
in the tank (related to the
average fuel consumption over
the last few miles (kilometres)
travelled).
Current fuel
consumption
(mpg or l/100 km or km/l)
Calculated over the last few seconds.
Average fuel
consumption
(mpg or l/100 km or km/l)
Calculated since the last trip
computer reset.
Distance travelled
(miles or km)
Calculated since the last trip
computer reset.
Average speed
(mph or km/h)
Calculated since the last trip
computer reset.
Distance remaining to
destination
(miles or km)
This is the distance remaining to be
travelled to the final destination. It
is either calculated instantly by the
navigation system, if guidance is
activated, or entered by the user.
If the distance is not entered, dashes
are displayed in place of the digits.
If dashes are displayed continuously
while driving in place of the digits,
contact a CITROËN dealer or a
qualified workshop. This value may vary following a change
in the style of driving or the relief,
resulting in a significant change in the
current fuel consumption. This function is only displayed from
20

mph (30 km/h).

Ventilation
Air flow paths
The incoming air follows various routes
depending on the controls selected by the
driver:
-
d
irect arrival in the passenger
compartment (air intake),
-
p

assage through a heating circuit (heating),
-

p
assage through a cooling circuit (air
conditioning).
The temperature control enables you to obtain
the level of comfort required by mixing the air of
the various circuits.
The air distribution control enables you to
diffuse the air in the passenger compartment
combining several air vents.
The air flow control enables you to increase or
reduce the speed of the ventilation fan.
Air intake
The air circulating in the passenger compartment
is filtered and originates either from the outside
via the grille located at the base of the windscreen
or from the inside in air recirculation mode.
Control panel
The controls of this system are grouped
together on control panel A on the centre
console. Depending on the model, the
functions offered are:
-

t

-

a
ir flow,
-
a

ir distribution,
-
d

emisting and defrosting,
-

In order for these systems to be fully effective, follow the guidelines on operation and
maintenance below:
F
I
f the interior temperature remains very high after the vehicle has been parked in the
sun for a considerable time, first ventilate the passenger compartment for a
few minutes.
P

lace the air flow control at a sufficient level to provide an adequate renewal of air in
the passenger compartment.
F

T
o obtain an even air distribution, take care not to obstruct the exterior air intake grilles
located at the base of the windscreen, the nozzles, the vents and the air outlets, as well
as the air extractor located in the passenger compartment on both sides of the rear shelf.
F

D
o not cover the sunshine sensor, located on the dashboard (behind the instrument
panel); this is used for regulation of the air conditioning system.
F

O
perate the air conditioning system for 5 to 10 minutes, once or twice a month to keep it
in good working order.
F

E
nsure that the passenger compartment filter is in good condition and have the filter
elements replaced regularly (see the "Checks" section).


W
e recommend the use of a combined passenger compartment filter. Thanks to its
second special active filter, it contributes to the purification of the air breathed by the
occupants and the cleanliness of the passenger compartment (reduction of allergic
symptoms, bad odours and greasy deposits).
F

T
o ensure correct operation of the air conditioning system, you are also advised to have
it checked regularly.
F

I
f the system does not produce cold air, do not use it and contact a CITROËN dealer or
a qualified workshop. The air conditioning system does not
contain chlorine and does not present
any danger to the ozone layer.
When towing the maximum load on a steep gradient in high temperatures, switching off the
air conditioning saves engine power and so improves towing capacity.
Recommendations for ventilation and air conditioning
The condensation created by the air
conditioning results in a discharge
of water under the vehicle which is
perfectly normal.

The control button is
located on the heating
or air conditioning
system control panel.
Rear screen demist/defrost
Switching on
The rear screen demist /defrost can only
operate when the engine is running.
F
P
ress this button to demist /defrost the rear

operation before it is switched off
automatically by pressing the button again.
The indicator lamp associated with the
button switches off.
F

S
witch off the demist /defrost
of the rear screen and door
mirrors as soon as you consider

4. Air intake / Air recirculation
The intake of exterior air prevents the formation
of mist on the windscreen and side windows.
The recirculation of interior air isolates the
passenger compartment from exterior odours
and smoke.
Return to exterior air intake as soon as possible
to prevent deterioration of the the air quality
and the formation of mist.F

ncrease the effectiveness of the demisting
in winter, above 3 °C.
Switching off
F Press the "A /C " button again, the button's
indicator lamp goes off.
Switching off may affect comfort levels
(humidity, condensation). The air conditioning is designed to
operate effectively in all seasons,
with the windows closed.
Switching on
F Press the "A /C "
button, the button's
indicator lamp comes on.

The air conditioning only operates when the engine is running.The driver and front passenger can
each adjust the temperature to their
requirements.
F

Turn control 2 or 3 to the left or to the right
respectively to decrease or increase this value.
A setting around the value 21 provides
optimum comfort. However, depending on your
requirements, a setting between 18 and 24 is
normal.
You are advised to avoid a left / right setting
difference of more than 3.
Automatic operation
F Press the "AUTO" button. The
indicator lamp in the button
comes on.
2. Driver's side adjustment
Dual-zone digital air conditioning
We recommend the use of this mode: it permits
automatic and optimised adjustment of all
of the functions, passenger compartment
temperature, air flow, air distribution and air
recirculation, in accordance with the comfort
value that you have chosen.
This system is designed to operate effectively
in all seasons, with the windows closed. The value indicated on the display corresponds
to a level of comfort and not to a temperature in
degrees Celsius or Fahrenheit.
1. Automatic comfort
programme 3. Passenger's side adjustment
On entering the vehicle, if the interior
temperature is much colder or warmer
than the comfort value, there is no
need to change the value displayed in
order to obtain the comfort required.
The system corrects the difference
in temperature automatically and as
quickly as possible.
When the engine is cold, to prevent
too great a distribution of cold air, the
air flow will reach its optimum level
gradually.
In cold weather, it favours the
distribution of warm air to the
windscreen, side windows and footwells
o n l y.
