Switching The System Off - CITROËN DS4 Owner's Handbook Manual

On switching on the engine
- The control screens come on: the function
is available.
- Pressing the REST button activates the
ventilation for a few minutes. Activation of
the function is confirmed by the display of
two dashes in the control screens and four
air flow level indicator lamps.
- The function can be deactivated and
reactivated if the control screens are on.
- The screens go off at the end of this period.
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.
On stopping the engine
- While the control screens remain on: the
function is available.
- Pressing the REST button activates the
ventilation for a few minutes. Activation of
the function is confirmed by the display of
two dashes in the control screens and four
air flow level indicator lamps.
Locking the vehicle has no effect on this
function.
- The control screens go off at the end of
this period.
Pressing again before the end of the period
interrupts off the ventilation definitively: the
control screens go off and the function is
no longer available.

Switching the system off

Turn the air flow control to
the left until all of the indicator
lamps go off.
This action switches off the air conditioning and
the ventilation.
Temperature related comfort is no longer
assured but a slight flow of air, due to the
movement of the vehicle, can still be felt.
Modify 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).
