DIGITAL AIR CONDITIONING (DUAL-ZONE)
Dual-zone: this is the differentiated regulation of the temperature and air distri-
bution on the driver's side and the front passenger's side.
The driver and front passenger can each adjust the temperature and the distri-
bution of the air to suit their requirements.
The symbols and messages associated with the digital air condit ioning controls
appear on the multifunction screen. This is the normal sys-
tem operating mode.
In accordance with the
level of comfort chosen,
pressing this control,
c o n fi r m e d b y t h e d i s p l a y
of indicator lamp A , permits auto-
matic and simultaneous control of
all of the following functions:
- A i r fl o w .
- Temperature in the passenger compartment.
- Air distribution.
- Air conditioning.
- Automatic air recirculation.
It is advisable to leave all of the
vents open. Simply pressing one
of the controls, with the exception
of temperature regulation 1a and
1b , switches the system to manual
mode. Indicator lamp A switches off.

2a-2b. Temperature adjustment Control via the manual controls
Press one of the controls, with
the exception of temperature
regulation 2a and 2b . The indi-
cator lamps A on the "AUTO"
controls switch off.
It is possible to adjust one or more
functions manually while leaving the
other functions in automatic mode.
Switching to manual mode may re-
sult in discomfort (temperature, hu-
midity, odour, condensation) and
may not provide optimum comfort.
To return to "AUTO" mode, press
controls 1a and 1b . The indicator
lamps A come on. 3a-3b. Air distribution adjustment
Press control
3a to change
the distribu-
tion of the air
fl o w o n t h e
driver's side.
Press control 3b to change the
d i s t r i b u t i o n o f t h e a i r fl o w o n t h e
passenger's side.
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.
Turn control 2a to change the
temperature on the driver's side
and control 2b to change the
temperature on the passenger's
side: to the right to increase the
temperature or to the left to re-
duce it.
The setting required is displayed.
The value indicated on the display
corresponds to a level of comfort
and not to a temperature in degrees
Celsius or Fahrenheit, depending on
t h e s c r e e n c o n fi g u r a t i o n .
A setting around the value 21 usually
makes it possible to obtain optimum
comfort. However, depending on
your requirements, a setting between
18 and 24 is usual.
On entering the vehicle, the interior
temperature may be much colder
(or warmer) than is comfortable.
There is no need to change the tem-
perature displayed in order to quickly obtain the level of comfort required.
The automatic regulation of the air
conditioning will use its maximum
performance settings to correct the
temperature difference as quickly as
possible.

Press the control:
- to increase the air fl o w ,
-
t o r e d u c e t h e a i r fl o w .
T h e a i r fl o w l e v e l i s i n d i -
cated by the progressive
lighting of the fan blade in-
dicator lamps.
R e d u c i n g t h e fl o w t o m i n i m u m
switches the air conditioning OFF.
To prevent condensation and dete-
rioration of the quality of the air in
the passenger compartment, ensure
t h a t a n a d e q u a t e fl o w o f a i r i s m a i n -
tained.
6. Air conditioning
The air conditioning will only
operate when the engine
is running. The air blower
c o n t r o l ( a i r fl o w a d j u s t m e n t )
must be active in order to
obtain air conditioning.
Press control 6 . The indicator
lamp comes on.
In order to be effective, the air con-
ditioning must be used with the win-
dows closed. 7. Air recirculation - intake of
exterior air
Automatic air intake
mode
It is activated by default in
automatic comfort regu-
lation.
Automatic mode is acti-
vated with reverse gear or
operation of the screen-
wash.
This function permits re-
circulation of the air and isolation
the passenger compartment from
exterior fumes and odours. It is inac-
tive when the ambient temperature
is below +5 °C to avoid the risk of
misting inside the vehicle.
Closing the air intake
Press control 7 to
close the exterior air
intake.
It must be cancelled as soon as pos-
sible to permit renewal of the air in
the passenger compartment and
demisting.
Intake of exterior air
Press control 7 once
to open the exterior air
intake.
While retaining the other settings,
this position allows the driver to iso-
late the passenger compartment at
any time from unpleasant exterior
odours and fumes.

When starting with the engine
c o l d , a i r fl o w w i l l r e a c h i t s o p t i -
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.
9. Front demisting - defrosting
In certain cases, the
"AUTO" mode may not
b e s u f fi c i e n t t o d e m i s t o r
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 temperature,
a i r fl o w a n d i n t a k e a n d d i s t r i b u t e s t h e
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
Switch off the rear screen and exterior
mirrors demisting when you consider
this necessary as low current con-
sumption reduces fuel consumption.
The heated rear screen
operates independently
of the air conditioning
system.
Press control 8 , with the en-
gine running, to demist the rear
screen and the mirrors. The indi-
cator lamp comes on.
Demisting is switched off automati-
cally to avoid excessive consump-
tion of current and depending on the
exterior temperature.
It may be stopped by pressing con-
trol 8 again or when the engine is
switched off.
In this latter case, the demisting re-
sumes if the engine is switched on
again within one minute.

call the corresponding position.
An audible signal is heard indicating
the end of the adjustment.
When the ignition is on, after a few
consecutive position recalls, the
function will be deactivated until the
engine is started, to prevent dis-
charging of the battery. For your safety, avoid storing a
driving position while driving.

CHECKS
Unless otherwise indicated, check
these components in accordance
with the Maintenance and Warranty
Guide and according to your engine.
Otherwise, have them checked by a
CITROËN dealer.
Battery The battery does not re-
quire any maintenance.
However, check that the
terminals are clean and
correctly tightened, particu-
larly in summer and winter.
When carrying out work on the bat-
tery, refer to the "Practical infor-
mation" section for details of the
precautions to be taken before dis-
connecting the battery and following
its reconnection.
Air filter and passenger compartment filter
Refer to the Maintenance
and Warranty Guide for
details of the replacement
intervals for these compo-
nents.
Depending on the environment (e.g.
dusty atmosphere) and the use of
the vehicle (e.g. city driving), replace
them twice as often if necessary
(refer to the “Engines” section).

of air quality by the retaining of the
unburnt pollutant particles. Black
exhaust fumes are thus no longer
emitted.
After prolonged idling or driving at very
low speeds, you may occasionally no-
tice water vapour being emitted from
the exhaust when accelerating. This is
of no consequence to the running of
the vehicle or to the environment.
If there is risk of clogging, a mes-
sage appears on the instrument
panel display, accompanied by an
audible signal and lighting of the
service warning lamp.
