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.
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 consump-
tion since the last trip computer zero
reset.
Average speed
(mph or km/h)
This is the average speed calculat-
ed 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.

RECOMMENDED SETTINGS FOR VENTILATION, HEATING AND AIR CONDITIONING Air inlet
Check that the exterior grille for the
air inlet, at the bottom of the wind-
screen, is clean and free of dead
leaves, snow, etc.
Air distribution
- Windscreen demisting/defrosting vents.
- Front side windows demisting/ defrosting vents.
- Adjustable and closing side air vents.
- Adjustable and closing central air vents.
- Front occupant footwell air outlets.

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 sun-
light the interior temperature is ex-
cessive, ventilate the passenger
compartment by opening the win-
dows for a few moments, 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 servicing
schedule (see "Maintenance and
Warranty Guide").
Air circulation
Maximum comfort is obtained when
there is a good distribution of air in
the passenger compartment, both in
the front and in the rear.
For optimum operating effi ciency,
take care not to obstruct the air out-
lets under the front seats.
Air vents
The face-level air vents 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
the sunshine sensor located on the
dashboard behind the instrument
panel.
Be careful not to obstruct it.

HEATING/VENTILATION

Air fl ow to the face level
vents.
1 - Adjustment of the air
distribution

Demisting - Defrosting.

Flow to the windscreen
and front side windows.

Distribution to the wind-
screen, side windows and
footwells.

Flow to front and rear pas-
senger footwells.
Distribution from the air blower can
be altered to suit your requirments
by placing the distribution control 1
in an intermediate position. 2 - Air recirculation
3 - Heater blower control
The air blower operates only when
the engine is running. For optimum
comfort in the passenger compart-
ment, the control should not remain
in position
"0" .
This position is for exclud-
ing disagreeable odours
or emissions coming from
outside the cabin. With a
press on control 2 , the entry of air
from outside is closed off, the lamp
comes on.
This should be cancelled as soon
as possible to prevent condensation
from forming and to allow fresh air
into the cabin.
To deactivate air recirculation, press
again on control 2 , the warning lamp
goes out.
