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.

T h i s fi l t e r h a s t o b e c h a n g e d i n a c -
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
a n d t h u m b w h e e l s t o a d j u s t t h e a i r fl o w
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.

be altered to suit your requirments
by placing the distribution control 1
in an intermediate position. 2 - Air recirculation
3 - H e a t e r b l o w e r c o n t r o l
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.

peratures on the right and on the left
cannot be greater than 3 degrees.
A setting around 21 will provide a
temperature that is comfortable.
Depending on your requirements,
an adjustment between 18 and 24 is
normal.
A press on this control, con-
fi r m e d b y t h e d i s p l a y o f

and "AUTO" , automatically
manages all the 5 following
functions according to the tempera-
ture chosen:

- Recycling of air.
To enable the system to operate, all
the air vents should be kept open. This is the normal operating
mode.
