Switching The System Off - CITROËN C4 Handbook

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.
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.
Ease of use and comfort

Switching the system off

F 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.
F 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
misting and deterioration of air quality).
