This automatic mode ensures optimum
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

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.
–
"Normal": offers the best compromise
between a comfortable temperature and quiet
operation (default setting).
–
"Fast": provides strong and effective air flow.
To change the current setting (shown by the
corresponding indicator lamp), press button

14

repeatedly until the desired setting is displayed.
To ensure passenger comfort in the rear seats,
favour "Normal" and "Fast" settings.
This setting is associated with automatic mode
only. However, on deactivation of
AUTO mode,
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.

Likewise, plus exchange of multimedia
data with the audio system.


USB sockets allow the connection of a portable
device.
The USB socket located at the front on the left-hand side also
allows a smartphone to be connected by Android
Auto® or CarPlay®, enabling certain smartphone
applications to be used on the touch screen.
For best results, use a cable made or approved
by the device manufacturer.
These applications can be managed using the
steering-mounted controls or the audio system
controls.
When the USB socket is used, the
portable device charges automatically.
While charging, a message is displayed if the
power drawn by the portable device exceeds
the current supplied by the vehicle.
For more information about how to use this
equipment, refer to the sections describing
the audio and telematics systems.
12 V accessory socket



► Plug in a 12 V accessory (with a maximum
rated power of 120 W) using a suitable adapter.
Observe the maximum power rating to
avoid damaging the accessory.
The connection of an electrical device not approved by CITROËN, such as a
USB charger, may adversely affect the
operation of vehicle electrical systems,
causing faults such as poor radio reception or
interference with displays in the screens.
Wireless smartphone
charger




This system allows wireless charging of a
portable device such as a smartphone, using the
magnetic induction principle, in accordance with
the Qi 1.1 standard.
The portable device to be charged must be
compatible with the Qi standard, either by design
or by using a compatible holder or shell.
A mat can also be used provided that it is
approved by the Manufacturer.
The charging area is identified by the Qi symbol.
The charger works with the engine running and
with the Stop & Start system in STOP mode.
Charging is managed by the smartphone.

temperature or humidity), misting on the
internal surface of the glass of the headlamps
and rear lamps is normal, and will disappear
after the lamps have been on for a few
minutes.
Never look too closely at the light beam
of LED technology lamps - risk of serious
eye injury!
