In the front part of the roof panel there is a steplessly adjusta-
ble air recirculation grille.When opening the grille, the outdoor

When the grille is open (fully open when the knob is in the
extreme position on the LH side) it is achieved:
--- Faster cab heating.

--- Greater coo l ing effect if the air conditioner is fitted.
When the grille is closed (the knob on the RH side) it is achie-
ved:
--- Better removal of moisture and prevention of icing
--- Greater pressurisation of the cab (reduced dust ingress)
