DUAL-ZONE DIGITAL AIR CONDITIONING
Automatic operation
We recommend the use of
one of the three AUTO modes
available: they provide opti-
mised regulation of the tem-
perature in the passenger
compartment according to the comfort
value that you have chosen.
These three modes automatically adjust
the air fl ow, according to the desired set-
ting, while also maintaining the desired
comfort value.
)
Press the "AU TO "
button repeatedly:
- a fi rst indicator lamp comes on; the
"light" setting mode is selected,
- a second indicator lamp comes
on; the "medium" setting mode is
selected,
- a third indicator lamp comes on;
the "intense" mode setting is se-
lected.
The air conditioning system operates when the engine is running. When the engine is cold, the air
fl ow will reach its optimum level
progressively, taking account
of the weather and the desired
comfort level so as to avoid too
great a distribution of cold air.
On entering the vehicle, if the in-
terior temperature is much colder
or warmer than the comfort val-
ue, there is no need to change
the value displayed in order to
obtain the comfort required. The
system corrects the difference in
temperature automatically and
as quickly as possible.
1. Automatic comfort programme
This system is designed to operate
effectively in all seasons, with the win-
dows closed.

Electric blind
Opening
Turn the dial to the left (four possible
settings).
Closing
Return the dial to the initial position.
Safety anti-pinch
If the blind encounters an obstacle dur-
ing closing, it stops and partially opens
again.
If the blind fails to close at a second at-
tempt, it may be necessary to force the
closing of the blind using the reinitiali-
sation procedure.
The blind is controlled electrically by a
rotary dial.
In the event of contact during op-
eration of the blind, you must re-
verse its movement. To do this,

tion,
)
then immediately press the dial, clos-
ing starts after about 10 seconds,

- front fog lamps with cornering lighting,
- directional headlamps for improved
visibility when cornering,
- daytime running lamps to be more
visible during the day,
- guide-me-home and welcome light-
ing to facilitate access to the vehicle,
