Headlight Washing (if equipped):When the headlights are on, the headlight washer
pump is activated with the first activation of the windshield washer pump. It is only activat-
ed again after five succesive windshield washer cycles during the same ignition key on cycle
(rest function). The GM recognises headlights on via K-Bus signalling. The GM provides a
ground on the headlight washer relay control circuit providing pump operation. The head-
light washer pump is located on the side of the washer fluid reservoir.
