Mode AUTO
The air conditioning system operates
automatically: the system manages the
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.

windows.
Recirculation of the interior air isolates the
passenger compartment from exterior odours
and fumes.When so required, this function also
allows faster heating or cooling of the air
in the passenger compartment.

Towing device
Load distribution
F D istribute the load in the trailer so that the
heaviest items are as close as possible to
the axle and the nose weight approaches
the maximum permitted without exceeding
it.
Air density decreases with altitude, thus
reducing engine performance. The maximum
towed load must be reduced by 10
% for every
1,000 metres of altitude.
Use towing devices and their genuine
harnesses approved by CITROËN. It is
recommended that the installation be
per formed by a CITROËN dealer or a
qualified workshop.
If the towing device is not fitted by
a CITROËN dealer, it must still be
fitted in accordance with the vehicle
manufacturer's instructions.
Certain driving or manoeuvring aid
functions are automatically disabled if an
approved towing device is used. Obser ve the maximum authorised towable
weight, indicated on your vehicle's
registration certificate, the manufacturer's
label as well as in the Technical data

section of this guide.
Complying with the maximum
authorised nose weight (ball joint)
also includes the use of accessories
(bicycle carriers, tow boxes, etc.).
Obser ve the legislation in force in the
country in which you are driving.
Remove the quickly detachable towball
when not towing a trailer.
Load reduction mode
System which manages the use of certain
functions according to the level of charge
remaining in the battery.
When the vehicle is being driven, the load
reduction function temporarily deactivates
certain functions, such as air conditioning,
heated rear screen, etc.
The deactivated functions are reactivated
automatically as soon as conditions permit.
Energy economy mode
System which manages the duration of use of
certain functions to conser ve a sufficient level
of charge in the battery.
After the engine has stopped, you can still use
functions such as the audio and telematics
system,
windscreen wipers, dipped beam
headlamps,
courtesy lamps, etc. for a
maximum combined duration of about forty
minutes.
Entering the mode
A message appears on the touch screen
indicating that the vehicle has switched to
economy mode and the active functions are put
o n st a n d by.
If a telephone call is being made at this
time, it will be maintained for around 10
minutes with the Bluetooth hands-free
system of your audio system.
Exiting the mode
These functions will be automatically restored
the next time the vehicle is used.
In order to restore the use of these functions
immediately, start the engine and let it run:

the corresponding section.
Checks
Unless otherwise indicated, check these
components in accordance with the
manufacturer's service schedule and according
to your engine.
Other wise, have them checked by a CITROËN
dealer or a qualified workshop.
12 V battery
The battery does not require any
maintenance.
However, check regularly that the
terminals are correctly tightened
(versions without quick release
terminals) and that the connections
are clean.
For more information on the precautions
to take before starting work on the
12 V batter y , refer to the corresponding
section. Versions equipped with Stop & Start are
fitted with a 12 V lead-acid battery of
specific technology and specification.
Its replacement should be carried out
only by a CITROËN dealer or a qualified
workshop.
Air filter
Depending on the environment
(e.g. dusty atmosphere) and the
use of the vehicle (e.g. city driving),
replace it twice as often, if
necessary
.
Passenger compartment
filter
Depending on the environment
(e.g. dusty atmosphere) and the
use of the vehicle (e.g. city driving),
replace it twice as often, if
necessary.
A clogged passenger compartment
filter may have an adverse effect on
the per formance of the air conditioning
system and generate undesirable odours.
Oil filter
Change the oil filter each time the
engine oil is changed.
Particle filter (Diesel)
The start of saturation of the particle
filter is indicated by the constant
