2023 CITROEN DS4 air conditioning

77
This function does not operate the air
conditioning, only the air blower.
When the "REST" function is activated,
you cannot modify the temperature, air
flow and distribution settings: these are
controlled automatically according to the
exterior temperature.
This function is not available when the
Stop & Start is in STOP mode.
Deactivating the system
F Turn the air flow control to the left until all indicator lamps are
of f.
This action switches off the air conditioning and
the ventilation.
Thermal comfort is no longer controlled.
A

slight flow of air can still be felt, resulting from
the for ward movement of the vehicle. F

M
odify one of the settings
(temperature, air flow or air
distribution) or press the
AUTO button to reactivate the
system with the values set
before it was switched off.
Avoid prolonged operation in interior
air recirculation mode or driving for
long periods with the system off (risk of
condensation and deterioration of air
quality).

Recommendations for ventilation and air conditioning
In order for these systems to be fully
effective, follow the operation and
maintenance guidelines below:
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

E
nsure that the passenger
compartment filter is in good condition
and replace the filter elements
periodically. We recommend the use of
a combined passenger compartment
filter. Thanks to its special active
additive, it helps both to purify the air
breathed by the occupants and to keep
the passenger compartment clean
(reduction of allergic symptoms, bad
odours and greasy deposits). F
T o ensure correct operation of the
air conditioning system, you are also
advised to have it checked regularly as
recommended in the Maintenance and
Warranty Guide.
F

I
f the system does not produce cold air,
switch it off and contact the dealer network
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.
To avoid the windows misting up and
deterioration in the quality of the air:
do not drive for too long with the ventilation
switched off.
Do not keep air recirculation set for an
extended period. If after an extended stop in sunshine, the
interior temperature is very high, first 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.
Stop & Star t
The heating and air conditioning systems
only work when the engine is running.
To maintain a comfortable temperature
in the passenger compartment, you can
temporarily deactivate the Stop & Start
system.
For more information on Stop & Star t ,
refer to the corresponding section.

conditioning, air flow and air intake, and provides
optimum distribution towards the windscreen and
side windows.
F
T
o stop the programme, press either the

before it is switched off
automatically by pressing the
button again. The indicator lamp
in the button goes out.
Rear screen demist –
defrost
Switching on
Demisting – defrosting of the rear screen can
only function when the engine is running.
Switching off
Demisting/defrosting switches off automatically
to prevent an excessive consumption of current.
F Press this button to demist /defrost the rear screen and
(depending on version) the door
mirrors. The indicator lamp in
the button comes on.
These markings on the control panel
indicate the control positions for
rapid demisting or defrosting of the
windscreen and side windows.
With Stop & Start, when the demisting/
defrosting, air conditioning and air flow
functions are activated, STOP mode is not
available. The control button is located on
the air conditioning system control

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...
The deactivated functions are reactivated
automatically as soon as conditions permit.
Energy saving mode
System that 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
equipment, windscreen wipers, dipped
beam headlamps,
courtesy lamps, etc. for a
maximum combined period of thirty minutes.
This period may be greatly reduced if the
battery is not fully charged.
Switching to this mode
Once this period has elapsed, a message
appears in the screen indicating that the
vehicle has switched to the energy saving
mode and the active functions are put on
st a n d by.If the telephone was operated via
the touch screen at that moment, the
connection would be interrupted after
10


minutes.
Exiting the mode
These functions will be automatically restored
the next time the vehicle is used.
F
I
n order to restore the use of these functions
immediately, start the engine and let it run
for a few minutes.
The time available to you will then be double
the period for which the engine is left running.
However, this period will always be between
five and thirty minutes.
The engine will not start if the battery is
discharged.

Practical information

Air filter and passenger compartment filter
Refer to the manufacturer’s
ser vice schedule for details of the
replacement intervals for these
components.
Depending on the environment (e.g. dusty
atmosphere) and the use of the vehicle (e.g.
city driving), replace them 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.
Refer to the manufacturer’s
ser vice schedule for details of
the replacement inter val for this
component.
Particle filter (Diesel)
Depending on the version of the instrument
panel you have, the start of saturation of the
particle filter is indicated by:
Manual gearbox
The gearbox does not require any
maintenance (no oil change).
Automatic gearbox
The gearbox does not require any
maintenance (no oil change).
- fixed illumination of the particle filter warning lamp, accompanied
by an audible signal and a
message that there is a risk of
blockage of the particle filter,
or
-
t
emporary illumination of
the Ser vice warning lamp,
accompanied by an audible
signal and a message that
there is a risk of blockage of the
particle filter. On a new vehicle, the first particle
filter regeneration operations may be
accompanied by a "burning" smell, which
is per fectly normal.
Following prolonged operation of the
vehicle at very low speed or at idle,
you may, in exceptional circumstances,
notice the emission of water vapour at the
exhaust on acceleration. This does not
affect the behaviour of the vehicle or the
environment.
Traffic conditions permitting, regenerate
the filter by driving at a speed of at least
37 mph (60 km/h) until the warning lamp
goes off.
If the warning lamp stays on, this indicates
a low Diesel additive level.
For more information on Checking levels ,
refer to the corresponding section.
