The temperature-related comfort is
no longer controlled (temperature,
humidity, odour, condensation).
Avoid driving for too long with the air
conditioning off.
In order to be effective, the air condi-
tioning must be used with the windows
closed.
Deactivating the air conditioning may
result in discomfort (temperature,
humidity, odour, condensation).
The indicator lamps corresponding
to the distribution chosen come on:
- Windscreen and front side win- dows.
- Front ventilation (central and side vents and air diffusion grille
if open) and rear ventilation.
- Front and rear footwells.
Simultaneous display of the distribu-
tion of air to the windscreen and side
windows and of front and rear venti-
lation is not possible. The air fl ow level is indicated by the
progressive lighting of the blocks of
the bar graph on the control panel

Recirculation of interior air
This function enables you to isolate
the passenger compartment from
exterior fumes and odours. - When starting with the engine
cold, the fl ow will reach its op-
timum level gradually to pre-
vent an excessive distribution
of cold air.
- When entering the vehicle af- ter it has been parked for a
fairly long period, if the inte-
rior temperature is very differ-
ent from your comfort setting
there is no need to change
the temperature displayed
in order to quickly reach the
level of comfort required. The
system automatically uses its
maximum performance to cor-
rect the difference in tempera-
ture as quickly as possible.
- The water resulting from the air conditioning condensation
is discharged via an open-
ing provided for this purpose;
therefore, a puddle of water
may form underneath the ve-
hicle when stationary.
- In all seasons, if the weather is cool, the air conditioning
is useful as it removes the
humidity from the air and the
condensation. Avoid driving
for prolonged periods with the
air conditioning switched off.
However, demisting resumes when
the engine is switched on again.
Switch off the rear screen and door
mirrors demisting when you consider
this necessary as low current con-
sumption reduces fuel consumption.

When starting with the engine
cold, air fl ow will reach its opti-
mum level gradually to prevent an
excessive distribution of cold air.
When entering the vehicle after it
has been parked for a fairly long
period, if the interior temperature
is very different from your comfort
setting there is no need to change
the temperature displayed in or-
der to quickly reach the level of
comfort required. The system
automatically uses its maximum
performance to correct the differ-
ence in temperature as quickly as
possible.
The water resulting from the air
conditioning condensation is dis-
charged via an opening provided
for this purpose; therefore, a pud-
dle of water may form underneath
the vehicle when stationary.
In all seasons, if the weather is
cool, the air conditioning is use-
ful as it removes the humidity
from the air and the condensa-
tion. Avoid driving for prolonged
periods with the air conditioning
switched off.

In certain cases, the

"AUTO" mode may not
be suffi cient to demist or
defrost the windows (hu-
midity, several passen-
gers, ice).

 Press control 9 to clear the win-
dows quickly. The indicator lamp
comes on.
This system controls the tempera-
ture, air fl ow and intake and distrib-
utes the ventilation to the windscreen
and front side windows.
Resuming manual control exits from
the "Demisting" mode. It must be
cancelled as soon as possible to
permit renewal of the air in the pas-
senger compartment and demisting.
Pressing one of the controls 1a and

1b returns the system to the "AUTO"
mode.
8. Rear demisting - defrosting

Changing the battery
The remote control is supplied by a
6 V-28L battery, which is supplied.
Information on the display indicates
when it is time to replace this battery.
Unclip the casing then replace the
battery.
The remote control must then be re-
initialised, see below. Always switch off the program-
mable heating while fi lling with
fuel to avoid any risk of fi re or ex-
plosion.
To avoid any risk of poisoning and
asphyxiation, the programmable
heating must not be used, even
for short periods, in an enclosed
space such as a garage or work-
shop which is not equipped with an
exhaust gas extraction system.
Do not park the vehicle on an
infl ammable surface (dry grass,
dead leaves, paper…), there is a
risk of fi re.
The programmable heating sys-
tem is supplied by the vehicle's fuel
tank. Before use, ensure that the
quantity of fuel remaining is suf-
fi cient. If the fuel tank is at the re-
serve, we strongly advise that you
do not programme the heating.
Do not discard the used bat-
teries, take them to an ap-
proved collection point.
Reinitialising the remote control
If the vehicle's battery is disconnect-
ed or the remote control's battery is
replaced, the remote control must
be reinitialised.
After switching on the power, press
button 4 (OFF) for 1 second within
the next 5 seconds. If the operation
has taken place correctly the mes-
sage "OK" is displayed on the re-
mote control screen.
If a problem occurs, the message

"FAIL" appears. Repeat the operation.
In addition, your programmable
heating can be used to pre-heat
your vehicle's passenger com-
partment. The interior volumetric protection
alarm movement sensor may be
disturbed by the fl ow of air from
the programmable heating when
it is in operation.
To avoid any unexpected trigger-
ing of the alarm during use of the
programmable heating, it is ad-
visable to deactivate the interior
volumetric protection.
