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.

Temporary manual operation
when in automatic mode
By pulling either of the " + " or " - " pad-
dles, you can exercise temporary
control over gear changing.
The request to change gear will be
taken into account. You will still be in
automatic mode. The warning lamp A
remains lit up in the instrument panel.
This function enables you to antici-
pate certain situations such as the
approach of a bend or the need to
overtake another vehicle.

 Move the selector to position A .
The warning lamp A lights up in
the instrument panel to confi rm
the selection.
The gearbox then functions in auto-
matic mode, without any action on
your part.
It constantly selects the gear that is
best suited to the following condi-
tions:
- driving style,
- road profi le,
- optimum fuel consumption.
Operation in automatic mode
Cancellation of automatic
mode
The change from position A (driving in
automatic mode) to position M (driv-
ing in manual mode) or vice versa can
be made at any time. The warning
lamp A disappears in the instrument
panel.
