As a safety measure, the mirrors should 
b e adjusted to reduce the blind spots.
The objects that you see in the mirrors are 
in fact closer than they appear.
Take this into account in order to 
correctly judge the distance of vehicles 
approaching from behind.
Folding
F From outside: lock the vehicle using the  remote control or the key.

F
 rom inside: with the 
ignition on, pull the control 
A from the central position 
rearwards.
If the mirrors are folded using control 
A , they will not unfold when the vehicle 
is unlocked. It will be necessary to pull 
control A again.
Unfolding

If necessary, the mirrors can be folded 
manually.
Automatic tilting in reverse gear
System which automatically tilts the mirrors 
downwards to assist with parking manoeuvres 
in reverse gear.
With the engine running, on engaging reverse 
gear, the mirror glasses tilt downwards.
They return to their initial position:
-

-
 
o
 nce the speed of the vehicle exceeds 
6

deactivated via the " Vehicle 
settings " tab in the Driving/Vehicle  
menu of the touch screen.

Rear seats
The 3 seats of the 2nd row are independent 
and of the same width. Their backrests are 
adjustable to adapt the boot load space.
Rear head restraints
The rear head restraints can be removed.
To remove a   head restraint:
F

go,
F
 
p
 ress the lugs A to release the head 
restraint and push it fully down. Never drive with passengers seated at 
the rear when the head restraints are 
removed; they must be in place and in the 
high position.
Longitudinal adjustment
Seat operations must only be done with 
the vehicle stationary.
Each seat can be adjusted individually.
F
 
Ra
 ise the control and slide the seat 
forwards or backwards.
They have two positions:
-
 
a  high position , for when the seat is in use:

restraint and push it fully down.
Once the backrest is folded, it is no longer 
possible to slide the seat.
Automatic "electrochrome " model
This system automatically and progressively 
changes between day and night use by means 
of a
 
s
 ensor measuring the light coming from the 
rear of the vehicle.
In order to ensure optimum visibility during 
your manoeuvres, the mirror lightens 
automatically when reverse gear is 
engaged.

Heating and Ventilation
Air entry
The air circulating in the passenger 
compartment is filtered and originates either 
from the outside via the grille located at the 
base of the windscreen, or from the inside in air 
recirculation mode.
Controls
The controls are accessible in the " Air 
conditioning " menu of the touch screen and 
are also grouped together on the control panel 
of the centre console.

conditioning system
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 
o r d e r.
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. Avoid driving for too long with the 
ventilation off and prolonged operation 
with recirculation of interior air – 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.
The condensation created by the air 
conditioning results in a   discharge of water 
under the vehicle which is per fectly normal.

Servicing the ventilation and air 
conditioning system
F 
E
 nsure that the cabin filter is in good 
condition and have the filter elements 
replaced regularly.
We recommend the use of a
  combined 
cabin 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.
Stop & Star t
The heating and air conditioning systems 
only work when the engine is running.

compartment in an optimum way according to 
the comfort level you have selected.
It is possible to adjust the intensity of the 
automatic comfort programme by choosing one 
of the settings offered in the secondary page, 
accessible from button 11  "OPTIONS ".
To change the current setting, shown by 
illumination of the corresponding indicator

repeatedly until the 
desired mode is displayed:
" 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.
Use the " Normal" or "Fast" modes to ensure 
the comfort of passengers in the rear seats.
This setting is associated with automatic mode 
only. However, on deactivation of AUTO  mode, 
the indicator lamp for the last setting remains 
on.
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 more quickly reach the required level 
of comfort. The system automatically 
corrects the temperature difference as 
quickly as possible.Automatic visibility

This function is not designed to detect 
unpleasant odours.
Recirculation is automatically activated when 
the front screenwash is used or when reverse 
gear is engaged.
The function does not operate if the exterior 
temperature is below 5°C, to avoid the risk of 
misting of the windscreen and side windows.
