3Heated seats



The function is active only with the engine
running and when the outside temperature is
below 20°C.
►
Press the button corresponding to the seat.
►


Each press changes the heating level; the
corresponding number of indicator lamps come
on.
►


T
o switch off the heating, press the button
until all of the indicator lamps are off.
The system status is memorised when the
ignition is switched off.
Do not use the function when the seat
is not occupied.
Reduce the heating intensity as soon as
possible.
When the seat and passenger compartment
have reached a satisfactory temperature,
switch the function off; reducing electrical
consumption in turn decreases energy
consumption.
Prolonged use of heated seats is not
recommended for people with sensitive
skin.
There is a risk of burns for people whose
perception of heat is impaired (e.g.
illness,
taking medication).
To keep the heated pad intact and to prevent
a short circuit:
–

Do not place heavy or sharp objects on the
seat.
–


Do not kneel or stand on the seat.
–


Do not spill liquids onto the seat.
–


Never use the heating function if the seat
is damp.
Steering wheel
adjustment


► When stationary , pull the control to release
the steering wheel.
► Adjust the height and reach to suit your
driving position.
►

Push the control to lock the steering wheel.
For safety reasons, these adjustments
must only be carried out with the vehicle
stationary.
Heated steering wheel
(Depending on country of sale)
In cold weather, this function heats the circular
part of the steering wheel.
It can be activated when the outside temperature
is below 20°C.




► With the engine running, press this button to
activate/deactivate the function (confirmed by the
indicator lamp coming on/going out).
The system is automatically deactivated every
time the engine is switched off.

Heating and Ventilation
Air intake
The air circulating in the passenger compartment
is filtered and originates either from the
exterior, via the grille located at the base of the
windscreen, or from the inside in air recirculation
mode.
Controls
Depending on version, the controls are
accessible in the touch screen or are
grouped together on the centre console panel.
Air distribution

1. Windscreen demisting/de-icing vents
2. Front side window demisting/de-icing vents
3. Adjustable and closable side air vents
4. Adjustable and closable central air vents
5. Air outlets to the front footwells
6. Air outlets to the rear footwells
7. Adjustable and closable air vents
Advice
Using the ventilation and air
conditioning system
►

T

o ensure that 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.
► Do not cover the sunshine sensor located
on the dashboard; this sensor is used to
regulate the automatic air conditioning
system.
►

Operate the air conditioning system for at
least 5 to 10 minutes once or twice a month to
keep it in good working order

.
►

If the system does not produce cold air
,
switch it off and contact a CITROËN dealer or
a qualified workshop.
When towing a large load on a steep gradient
in high temperatures, switching off the air
conditioning increases the available engine
power, enhancing the towing capacity.
Avoid driving for too long with the ventilation off or with prolonged operation
of interior air recirculation. Risk of misting and
deterioration of the air quality!
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.
Condensation created by the air
conditioning results in a discharge of
water underneath the vehicle. This is perfectly
normal.

52
Ease of use and comfort
Servicing the ventilation and air
conditioning system
►

Ensure that the passenger compartment
filter is in good condition and have the filter
elements replaced regularly

.
We recommend using a composite passenger
compartment filter. Its specific active additive
helps protect against polluting gases and bad
smells.
►

T

o ensure correct operation of the
air conditioning system, have it checked
according to the recommendations in the
Manufacturer’s service schedule.
Stop & Start
The heating and air conditioning systems
only operate when the engine is running.
Temporarily deactivate the Stop & Start
system to maintain a comfortable temperature
in the passenger compartment.
For more information on the Stop &
Start
system, refer to the corresponding
section.
ECO driving mode
Selecting this mode reduces electrical
energy consumption, but restricts the
performance of the heating and air
conditioning systems, although it does not
deactivate them.

management of the passenger compartment
temperature, air flow and air distribution, based
on the selected comfort level.
►

Press knob
3 on the central controls or button
10 on the touch screen to activate/deactivate the
air conditioning system's automatic mode.
The indicator lamp in the button lights up
when the air conditioning system is operating
automatically.
You can adjust the intensity of the
automatic Comfort programme by using the
"OPTIONS "
button to select one of the available
settings:
–
"Soft": provides soft and quiet operation by
limiting air flow.

the indicator lamp for the most recently selected
setting remains on.
Changing the setting does not reactivate AUTO
mode if it was 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 to more
quickly reach the required level of comfort.
The system automatically corrects the
temperature difference as quickly as possible.
