Front windshield (B) defrosting
To ensure quick defrosting of the front windshield direct
the central heating outlets (1) under the angle of approx.
45° towards the windshield. Direct the side outlets (2)
under the angle of approx. 45° to the cab corners. After
defrosting of the front windshield direct the side outlets to
the side glasses of the doors as necessary and gradually
defrost them. After defrosting direct the outlets in such
a way that the air should not be blown directly to the
driver, but down to the driver's legs.
