Ease of use and comfort
To return to the normal position, guide the
backrest backwards until it locks into place.
This position, together with that of the rear seats,
allows you to transport long objects inside the
vehicle.
Before moving the seat backwards,
ensure that there is nothing that might
prevent the full travel of the seat.
When the front passenger seat is fully folded,
only the outer rear seat behind the driver can
be occupied by a passenger.
Do not place hard, heavy or sharp
objects in the centre of the backrest to
ensure that you don't damage rear lining
behind the backrest.
When sharp deceleration occurs, objects
placed on the folded backrest can turn into
dangerous projectiles.
Heated seats

► With the engine running, use the adjustment knob to switch on and select the level of heating
required:
0
: Off.
1 : Low.
2 : Medium.
3 : High.
The front seats can be heated individually.
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 (illness, taking
medication, etc.).
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.
Rear seats
Bench seat with a fixed cushion or on rails
(depending on version) and split folding
backrests (2/3-1/3) to adapt the boot loading
space.
Rear head restraints

They have two positions:– a high position , for when the seat is in use:► pull the head restraint fully up.– a low position, for stowing, when the seat is
not in use:
► press the lug A to release the head
restraint and push it fully down.

Advice
Using the ventilation and air
conditioning system
► To 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 perfect working order.
► If 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, 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.
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. Thanks to its special active
additive, this type of filter helps to purify the
air breathed by the occupants and keep the
passenger compartment clean (by reducing
allergic symptoms, unpleasant odours and
greasy deposits).
► To ensure correct operation of the air conditioning system, have it checked
according to the recommendations in the
Maintenance and Warranty Guide.
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,
refer to the corresponding section.

Temperature adjustment
► Press one of the buttons 1 to increase (red)
or decrease (blue) the value.
The value displayed corresponds to a level of
comfort and not to a precise temperature.
For maximum cooling or heating of the
passenger compartment, press the
temperature setting button up or down until
LO or HI is displayed.
Automatic comfort programme
Activation/Deactivation
► Press button 5 to activate or deactivate the
air conditioning system’s automatic mode.
The air conditioning system operates
automatically: the system optimises the
temperature, air flow and air distribution in the
passenger compartment based on the comfort
level selected.
► Go to the secondary page by pressing button 7 to adjust the automatic comfort programme by
choosing one of the available settings.
“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.
Mode AUTO► To change the settings, press the button several times.
The setting is associated with AUTO mode only. However, when AUTO mode is deactivated, the
previous selection is retained.
Changing the setting does not reactivate AUTO
mode if this 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 reach
the required level of comfort more quickly.
The system automatically corrects the
temperature difference as quickly as possible.
Air flow adjustment
► Press one of the buttons 2 (- or +) to increase
or decrease air flow.
The air flow symbol (a fan) is filled in according
to the request.
When the air flow is reduced to a minimum,
ventilation stops.
"OFF " is displayed alongside the fan.
Adjusting the air distribution
► Press the buttons 3 to adjust the air flow
distribution inside the passenger compartment.
