The driver’s side defroster grille is adjustable. The normal position as
shown in the diagram directs warm air to the side glass. When more
rapid defrosting of the windshield is desired, the air flow can be
directed temporarily toward the windshield to assist the windshield
defroster. If this is done, the driver’s side grille should always be
returned to its normal position so that the warm air flow can then be
used to defrost the driver’s side window.
