the à and ¿ buttons light up.

into the vehicle in air-recirculation mode.

perature settings on the driver's side for
the front-passenger side and the rear com-
partment as well. The indicator lamp above

heat function can only be activated or deac-
tivated with the ignition switched off.

control system, the climate status display
