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.

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.

useful in poor light.
M a n u a l d a y / n i g h t m o d e l
Adjustment
Adjust the mirror so that the
glass is directed correctly in the
"day" position.
D a y / n i g h t p o s i t i o n
Pull the lever to change to the
"night" anti-dazzle position.
Push the lever to change to the
normal "day" position. By means of a sensor, which mea-
sures the light from the rear of the
vehicle, this system automatically
and progressively changes between
the day and night uses.
It has an anti-dazzle system which
darkens the mirror glass: this reduc-
es any driver discomfort caused by
the light beam of following vehicles,
the sun...
In order to guarantee optimum vis-
ibility during your manoeuvres, the
mirror lightens automatically when
reverse gear is engaged.
STEERING WHEEL ADJUSTMENT
The height and reach of the steer-
ing wheel can be adjusted to adapt
the driving position to the size of the
driver.
Adjustment
First, adjust the driver's seat to
the most suitable position.
W h e n s t a t i o n a r y , pull the con-
trol lever to unlock the steering
wheel adjustment.
Adjust for height and reach.
Push the control lever to lock the
steering wheel adjustment.
A f t e r l o c k i n g , i f y o u p r e s s fi r m l y o n
the steering wheel, a slight click may
be heard.
As a safety precaution, the mirrors
must be adjusted to reduce the
"blind spot".
A u t o m a t i c d a y / n i g h t m o d e l
As a safety precaution, these op-
erations must only be carried out
while the vehicle is stationary.

C. Foglamps selection ring.
The foglamps operate with the side-
lamps and the dipped and main
beam headlamps.

Model with rear foglamp only Model with front and rear
foglamps
In good or rainy weather, both day and night, the front foglamps and the rear
foglamp are prohibited. In these situations, the power of their beams may
dazzle other drivers. They should only be used in fog or snow.
In these weather conditions, it is your responsibility to swit ch on the foglamps
and dipped beam headlamps manually as the brightness sensor may d etect
s u f fi c i e n t l i g h t .
Do not forget to switch off the front foglamps and the re ar foglamp when they
are no longer necessary. Switching off of the lamps when
the ignition is switched off
On switching off the ignition, all of the
lamps turn off immediately, except
for dipped beam if guide-me-home
lighting is activated.
Switching on the lamps after
the ignition is switched off
To reactivate the lighting control, ro-
tate ring
A to the "0" position - lamps
off, then to the desired position.
On opening the driver’s door a
temporary audible signal warns the
driver that the lighting is on.
The lamps, with the exception of
the sidelamps, switch off automati-
cally after a maximum duration of
thirty minutes to prevent dischar-
ging of the battery.
In some weather conditions (e.g.
l o w t e m p e r a t u r e o r h u m i d i t y ) , t h e
presence of misting on the internal
surface of the glass of the head-
lamps and rear lamps is normal;
it disappears after the lamps have
been on for a few minutes.
