Ventilation / Heating

Air intake

The air circulating in the passenger
compartment is filtered and originates either
from the outside via the grille located at the
base of the windscreen or from the inside in air
recirculation mode.
Air treatment
The incoming air follows various routes
depending on the controls selected by the
driver:
- direct arrival in the passenger
compartment (air intake),
- passage through a heating circuit (heating),
- passage through a cooling circuit (air
conditioning).

Control panel

The controls of this system are grouped
together on control panel A on the centre
console.
