MULTIFUNCTION SCREENS





A few definitions…


Range
(miles or km)
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 con-
sumption.
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 dis-
played when it exceeds 60 miles
(100 km).
If dashes are displayed continu-
ously while driving in place of the
digits, contact a CITROËN dealer
or a qualifi ed workshop. This indicates the distance which
can still be travelled with the fuel re-
maining in the tank in relation to the
average fuel consumption over the
last few miles (kilometres) travelled.
Current fuel consumption
(mpg or l/100 km or km/l)

Average fuel
consumption
(mpg or l/100 km or km/l)
This is the average fuel
consumption since the last trip com-
puter zero reset.

Average speed
(mph or km/h)
This is the average speed calculated
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.



Distance remaining to
destination
(miles or km)
This is the distance remaining to be
travelled to the fi nal destination. It
is either calculated instantly by the
navigation system, if guidance is ac-
tivated, or entered by the user.
If the distance is not entered, dashes
are displayed in place of the digits.
This function is only displayed from
20 mph (30 km/h). This is the average fuel consump-
tion during the last few seconds.
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 igni-
tion is switched on with the key.

Air conditioning

To ensure that your system operates
correctly, it is recommended that you
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 preserve the sealing of the air
conditioning compressor, operate
the air conditioning at least once a
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 servicing
schedule (see the servicing booklet).


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 thumb wheels to adjust the air
fl ow and direction (up-down, right-
left).
The automatic regulation of the air
conditioning in the passenger com-
partment uses a number of sensors
(sunshine sensor, ambient tempera-
ture sensor...) that relieve you of the
need to make frequent adjustments to
the displayed temperature.
Take care not to obstruct the sun-
shine sensor, located on the dash-
board behind the instrument panel.

perature selected, of all the following
5 functions:

- passenger compartment tem-
perature, left and right,

- air distribution,

- air conditioning,

- automatic air recirculation.

For this facility to operate, it is recom-
mended that all air vents are kept
open.
Using the AUTO
mode will prevent
the formation of mist inside the ve-
hicle in cold or humid weather.
When starting from cold, in order to
avoid a rush of cold air, the air fan
attains its optimum level progres-
sively.

2. Adjustment of temperature

To display the desired temperature,
press button:


- -
to decrease the temperature,

- +
to increase the temperature.
A setting around 21 will provide
an agreeable temperature level.
However, depending on your prefer-
ence, anything between 18 and 24
is quite normal.
For optimum comfort, it is recom-
mended to avoid a difference of set-
tings of more than than 3 between
right and left.
Actual temperatures experienced in
the passenger compartment are de-
pendent on external factors and for
this reason might not be identical to
those displayed.
On entering the vehicle, the inside
temperature may be much colder (or
hotter) than would be comfortable. It
serves no purpose to alter the tem-
perature displayed in an attempt to
attain your preference more rapidly.
The system operates automatically
to correct the difference in tempera-
ture as soon as possible.
