engine Citroen DS4 RHD 2015.5 1.G Owner's Guide

Dual-zone digital air conditioningThe air conditioning system operates when the engine is running.
Automatic operation
1. Automatic comfort programme
We recommend the use of one of
the three AUTO modes available:
they provide optimised regulation of
the temperature in the passenger
compartment according to the comfort value
that you have chosen.
These three modes automatically adjust the
air flow, according to the desired setting, while
also maintaining the desired comfort value. F
P ress the "AUTO" button repeatedly:
-

a f
irst indicator lamp comes on; the
"light" setting mode is selected,
-

a s
econd indicator lamp comes on; the
"medium" setting mode is selected,
-

a t
hird indicator lamp comes on; the
"intense" mode setting is selected. When the engine is cold, the air
flow will reach its optimum level
progressively, taking account of the
weather and the desired comfort level
so as to avoid too great a distribution
of cold air.
On entering the vehicle, if the interior
temperature is much colder or warmer
than the comfort value, there is no
need to change the value displayed in
order to obtain the comfort required.
The system corrects the difference
in temperature automatically and as
quickly as possible.
This system is designed to operate effectively
in all seasons, with the windows closed.

5. Air conditioning On / Off
F Press this button to switch off the air conditioning.
Switching the system off could result in
discomfort (humidity, condensation).

P

ress this button again to return to
automatic operation of the air conditioning.
The indicator lamp on the "A /C " button
comes on.
6. Air distribution adjustment
F Press one or more buttons to direct the air flow towards:
-

t
he windscreen and side
windows (demisting or
def r o st ing),
-

t
he outer and centre air
vents,
-

t
he footwells.
You can combine the three orientations to
obtain the desired air distribution.
7. Air flow adjustment
F Turn this control to the left to decrease the air flow or to the
right to increase the air flow.
8. Air intake / Air recirculation
F Press this button for recirculation of the interior air. The indicator
lamp in the button comes on.
The air flow indicator lamps, between the two
fans, come on progressively in relation to the
value requested.
9. "REST" function: ventilation
with the engine off
Even with the engine is off, you
can operate the ventilation for a
few
m

inutes.
Air recirculation enables the passenger
compartment to be isolated from exterior
odours and smoke.
F

A

s soon as possible, press this button
again to permit the intake of outside air and
prevent the formation of condensation. The
indicator lamp in the button goes off. For example, while you are away from the
vehicle, the passengers can still enjoy some air
circulation without having the engine running.
This function is available after switching on the
ignition, as well as after stopping the engine.
The period that the function is available
depends on the state of charge of the battery.
You can activate the "REST" function while the
air conditioning control screens are on.
Avoid prolonged operation in interior air
recirculation mode (risk of misting and
deterioration of air quality).

Switching the system off
F Turn the air flow control to the left until all of the indicator
lamps go off.
This switch does not operate the air conditioning, only the air fan.
When the "REST" function is activated, you cannot modify the temperature, air flow
and distribution settings: these are controlled automatically according to the ambient
temperature.
This function is not available in the STOP mode of Stop & Start. Avoid prolonged operation in interior
air recirculation mode or driving for
long periods with the system off (risk of
misting and deterioration of air quality).

Low screenwash / headlamp
wash fluid level
On vehicle fitted with headlamp washers, the
low level of this fluid is indicated by gauge in
the reservoir filler neck under the bonnet.
Checking and topping up this fluid can should
be done with the engine off.
The level of this fluid should be
checked regularly, particularly during
w i n t e r.
Refer to the "Checks - Screenwash / headlamp
wash level" section for the procedure on
checking the level.
Headlamp wash
Associated with the windscreen wash, the
headlamp washers operate with the vehicle
moving, when the dipped or main beam
headlamps are on .
To reduce the consumption of the fluid
by the headlamp washers, they operate
only with every seventh use of the
screenwash or every 25 miles (40 km)
during a given journey.

Emergency braking assistance
System which, in an emergency, enables you
to obtain the optimum braking pressure more
quickly, thus reducing the stopping distance.
Activation
It is triggered by the speed at which the brake
pedal is pressed.
The effect of this is a reduction in the
resistance of the pedal and an increase in
braking efficiency.When braking in an emergency, press
firmly without releasing the pressure.
Trajectory control systems
Anti-slip regulation (ASR)
and dynamic stability
control (
d
SC)
The anti-slip regulation (also known as traction
control) optimises traction to prevent skidding
of the wheels, by acting on the brakes of the
driving wheels and on the engine.
The electronic stability control acts on the brake
of one or more wheels and on the engine to
keep the vehicle on the trajectory required by
the driver, within the limits of the laws of physics.
Activation
These systems are activated automatically
each time the vehicle is started.
They come into operation in the event of a grip
or trajectory problem.
This is indicated by flashing of this
warning lamp in the instrument panel.
Intelligent traction control
system ("Snow motion")
Depending on version, your vehicle has a
system to help driving on snow: intelligent
traction control .
This system detects situations of difficult
sur face adhesion that could make it difficult to
move off or make progress on deep fresh snow
or compacted snow.
In these situations, the intelligent traction
control limits the amount of wheel slip to
provide the best traction and trajectory control
for your vehicle.
The use of snow tyres is strongly
recommended on sur faces offering low
levels of adhesion.
