Headlamp High-Low Beam To change the headlamps from low beam to high or high to low, pull the multifunction lever all the way toward you. Then release it. When the high beams are on, this blue indicator light on the instrument panel also will be on. Windshield Wipers You control the windshield wipers by turning the band with the wiper symbol on it. For a single wiping cycle, turn the band to MIST. Hold it there until the wipers start, then let go. The wipers will stop after one wipe. If you want more wipes, hold the band on MIST longer. 2-36
