A few definitions…

This value may vary following a
change in the style of driving or
the relief, resulting in a signifi -
cant change in the current fuel
consumption.
If dashes are displayed continu-
ously while driving in place of the
digits, contact a CITROËN dealer
or a qualifi ed workshop. This function is only displayed
from 20 mph (30 km/h).
Range
(miles or km)
This indicates the distance
which can still be travelled
with the fuel remaining in the tank in
relation to the average fuel consump-
tion over the last few miles (kilometres)
travelled.
When the range falls below 20 miles
(30 km), dashes are displayed. After
fi lling with at least 5 litres of fuel, the
range is recalculated and is displayed
when it exceeds 60 miles (100 km).
Current fuel consumption
(mpg or l/100 km or km/l)
This is the average fuel con-
sumption during the last few
seconds.

Average fuel consumption
(mpg or l/100 km or km/l)

This is the average fuel con-
sumption since the last trip
computer zero reset.
Average speed
(mph or km/h)
This is the average speed calcu-
lated since the last trip computer
zero reset (ignition on).

Distance travelled
(miles or km)
This indicates the distance
travelled since the last trip
computer zero reset.








Stop & Start time counter
(minutes/seconds or hours/
minutes)
If your vehicle is fi tted with Stop & Start,
a time counter calculates the time spent
in STOP mode during a journey.
It resets to zero every time the ignition
is switched on with the key.

The fuel consumption of your
vehicle will be higher than
the offi cial fi gures obtained
by CITROËN during the fi rst
3 000 miles (5 000 km) of the
vehicle's life.

VENTILATION

Air intake

The air circulating in the passenger
compartment is fi ltered and originates
either from the outside via the grille
located at the base of the windscreen
or from the inside in air recirculation
mode.


Air treatment

The incoming air follows various routes
depending on the controls selected by
the driver:


- direct arrival in the passenger com-
partment (air intake),

- passage through a heating circuit
(heating),

- passage through a cooling circuit
(air conditioning).

Control panel

The controls of this system are grouped
together on control panel A
on the centre
console.

RECOMMENDATIONS FOR VENTILATION AND AIR CONDITIONING
In order for these systems to be fully effective, follow the operation and
maintenance guidelines below:


)
To 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
boot.

)
Do not cover the sunshine sensor, located on the dashboard; this is
used for regulation of the digital air conditioning system.

)
Operate the air conditioning system for at least 5 to 10 minutes, once or
twice a month to keep it in perfect working order.

)
Ensure that the passenger compartment fi lter is in good condition and have
the fi lter elements replaced regularly (refer to the "Checks" section).
We recommend the use of a combined passenger compartment fi lter.
Thanks to its special active additive, it contributes to the purifi cation of
the air breathed by the occupants and the cleanliness of the passenger
compartment (reduction of allergic symptoms, bad odours and greasy
deposits).

)
To ensure correct operation of the air conditioning system, you are
also advised to have it checked regularly as recommended in the
Maintenance and Warranty Guide.

)
If the system does not produce cold air, switch it off and contact a
CITROËN dealer or a qualifi ed workshop.
When towing the maximum load on a steep gradient in high temperatures,
switching off the air conditioning increases the available engine power and
so improves the towing ability.
If after an extended stop in sun-
shine, the interior temperature is
very high, fi rst ventilate the pas-
senger compartment for a few
moments.
Put the air fl ow control at a set-
ting high enough to quickly
change the air in the passenger
compartment.
The air conditioning system
does not contain chlorine and
does not present any danger to
the ozone layer.

The condensation created by
the air conditioning results in a
discharge of water under the ve-
hicle which is perfectly normal.

the the air quality and the formation of
mist. The air conditioning does not
operate when the air fl ow adjust-
ment control 2
is in position " 0 ".

DUAL-ZONE DIGITAL AIR CONDITIONING

Automatic o
peration

We recommend the use of one
of the three AUTO modes avail-
able: they provide optimised
regulation of the temperature
in the passenger compartment
according to the comfort value that you
have chosen.
These three modes automatically adjust
the air fl ow, according to the desired set-
ting, while also maintaining the desired
comfort value.

)
Press the "AUTO"
button repeat-
edly:


- a fi rst indicator lamp comes on; the
"light" setting mode is selected,

- a second indicator lamp comes
on; the "medium" setting mode is
selected,

- a third indicator lamp comes on; the
"intense" mode setting is selected.
The air conditioning system operates when the engine is running. When the engine is cold, the air
fl ow will reach its optimum level
progressively, taking account
of the weather and the desired
comfort level so as to avoid too
great a distribution of cold air.
On entering the vehicle, if the in-
terior temperature is much colder
or warmer than the comfort val-
ue, 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.

1. Automatic comfort programme
This system is designed to operate ef-
fectively in all seasons, with the windows
closed.

away from the vehicle, the pas-
sengers can still enjoy some air circula-
tion without having the engine running.
This function is available after switching
on the ignition, as well as after stopping
the engine.
The period that the function is available
depends on the state of charge of the
battery.
You can activate the "REST" func-
tion while the air conditioning control
