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.

carbon)

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.
F o r o p t i m u m o p e r a t i n g e f fi c i e n c y ,
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 o w a n d d i r e c t i o n ( u p - d o w n , r i g h t -
left).
The automatic regulation of the air
conditioning, inside the cabin, uses
the sunlight sensor located on the
dashboard behind the instrument
panel.
Be careful not to obstruct it.

sions coming from outside
the cabin. With a press on

To set and display the de-
sired temperature, rotate
control 2 or 3 :
The display HI (high) corre-
sponds to a demand for max-
imum heating (above 27).

When you enter the vehicle, the
temperature inside the vehicle
may be much colder (or warmer)
than a comfortable temperature.
There is no point in modifying
the displayed temperature to
try to attain the desired level of
comfort. The system operates
automatically to compensate this
temperature discrepancy as rap-
idly as possible.
When starting the engine from
cold, in order to avoid distributing
too much cold air, the blower will
attain its optimum level gradually.
