Recommendations for ventilation and air conditioning
In order for these systems to be fully
effective, follow the operation and
maintenance guidelines below:
F
T
o ensure that the air is distributed
evenly, keep the external air intake
grilles at the base of the windscreen, the
nozzles, the vents, the air outlets and
the air extractor in the boot free from
obstructions.
F

D
o not cover the sunshine sensor,
located on the dashboard; this is used
for regulation of the automatic air
conditioning system.
F

O
perate the air conditioning system for
at least 5 to 10 minutes once or twice a
month to keep it in per fect working order.
F

R
eplace the filter elements regularly.
We recommend the use of a combined
passenger compartment filter. Thanks to
its special active additive, it contributes
to the purification of the air breathed by
the occupants and the cleanliness of
the passenger compartment (reduction
of allergic symptoms, bad odours and
greasy deposits).
F

T
o ensure correct operation of the air
conditioning system, have it checked
according to the recommendations in the
Maintenance and Warranty Guide. F
I f the system does not produce cold air,
switch it off and contact a CITROËN
dealer or a qualified workshop.
When towing the maximum load on a steep
gradient in high temperatures, switching off
the air conditioning increases the available
engine power and so improves the towing
ability.
To avoid the windows misting up and
deterioration in the quality of the air:
-

d
o not drive for too long with the
ventilation switched off.
-

d
o not keep air recirculation set for an
extended period. If the interior temperature is very high
after the vehicle has stood for a long
time in the sunshine, air the passenger
compartment for a few moments.
Put the air flow control at a setting high
enough to quickly change the air in the
passenger compartment.
The condensation created by the air
conditioning results in a discharge of water
under the vehicle which is per fectly normal.
Stop & Star t
The heating and air conditioning systems
only work when the engine is running.
Temporarily deactivate the Stop &
Start system to maintain a comfortable
temperature in the passenger
compartment.
For more information on Stop & Star t ,
refer to the corresponding section.

when the air flow adjustment is inhibited.
Switching the system off
F Press this button; the indicator lamp in the button comes on.
This action switches off all of the functions of
the system.
The temperature is no longer controlled.
However, a slight flow of air, due to the
movement of the vehicle, can still be felt.
Pressing any button reactivates the system with
the settings that were previously in use. Avoid driving for long periods with
the system off – Risk of misting and
deterioration of air quality!
Automatic air conditioning

temperature, air flow and air distribution in
the passenger compartment in an optimum
way according to the comfort level you have
selected.

button 6 " OPTIONS " to adjust the automatic
comfort programme by choosing one of the
available settings.
F

T
o change the current setting,
press the button several times in
succession to access the desired
mode:
" Soft ": provides soft and quiet operation by
limiting air flow.
" Normal ": offers the best compromise between
a comfortable temperature and quiet operation
(default setting).
" Fast ": provides strong and effective air flow.
This setting is associated with AUTO mode
only. However, on deactivation of AUTO mode,
the last setting used remains set.
Changing the setting does not reactivate AUTO
mode if deactivated. In cold weather with the engine cold, the
air flow is increased gradually until the
comfort setting has been reached, in order
to limit the delivery of cold air into the
passenger compartment.
On entering the vehicle, if the interior
temperature is much colder or warmer
than the comfort setting requested, there
is no need to alter the value displayed
in order to reach more quickly the
required level of comfort. The system
compensates automatically and corrects
the temperature difference as quickly as
possible.
You can manually adjust the air flow and
distribution.
As soon as you modify a setting, the automatic
comfort programme is deactivated.

Panoramic glazed sunroof
This glazed roof provides increased visibility
and light in the passenger compartment, while
maintaining normal temperatures thanks to its
"high thermal protection" coating.
Advice on care
In order to preser ve the properties of the
glazed roof, we recommend wiping or cleaning
the inner glass using a clean, soft and dry
cloth.
For stubborn stains, the glass should be
cleaned using screenwash fluid, rinsed with
clean water, then dried with a clean, soft cloth.
Do not use soapy water, abrasive
products, detergents (particularly those
with an ammonia base), solvents,
solutions with a high concentration of
alcohol, petrol, etc.

Definitions
Anti-lock braking system (ABS)
and electronic brake force
distribution (EBFD)
This system improves the stability and
manoeuvrability of your vehicle when braking and
contributes towards improved control on corners, in
particular on poor or slippery road sur faces.
The ABS prevents wheel lock in the event of
emergency braking.
The electronic brake force distribution system (EBFD)
manages the braking pressure wheel by wheel.
Emergency braking assistance
(EBA)
In an emergency, this system permits the
optimum braking pressure to be reached
more quickly, therefore reducing the stopping
distance.
It is triggered in relation to the speed at which
the brake pedal is pressed. The effect of this is
a reduction in the resistance of the pedal and
an increase in braking efficiency.
Anti-slip regulation (ASR)
The ASR system (also known as Traction
Control) optimises traction in order to limit
wheel slip by acting on the brakes of the driving
wheels and on the engine. It also improves
the directional stability of the vehicle on
acceleration.
Dynamic stability control (DSC)
If there is a difference between the path
followed by the vehicle and that required by
the driver, the DSC monitors each wheel and
automatically acts on the brake of one or more
wheels and on the engine to return the vehicle
to the required path, within the limits of the laws
of physics.
If you benefit from the Citroën Connect
Box offer with the SOS and assistance
pack included, there are additional
ser vices available to you in your personal
space, via the website for your country.
Anti-lock braking system
(ABS) and electronic brake
force distribution (EBFD)
The fixed illumination of this warning
lamp indicates that there is a fault
with the ABS.
If this warning lamp comes on, in
conjunction with the STOP
and
ABS warning lamps, an audible
signal and a message, this indicates
that the electronic brake force
distribution (EBFD) is faulty.
You must stop as soon as it is
safe to do so.
In both cases, have the system
checked by a CITROËN dealer or
a qualified workshop as soon as
possible.
When changing wheels (tyres and rims),
ensure that these are approved for your
vehicle.
Normal operation of the ABS may make
itself felt by slight vibration of the brake
pedal.
If you need to brake in an emergency,
press the brake pedal ver y firmly and
keep the pressure applied.
