Apply brakes sooner and press brake treadle (4) lightly to give early
warning that vehicle will slow or stop.
Downshift, if necessary, when slowing or stopping vehicle on slick
surfaces.
Keep windshield, windows, mirrors, headlights, stoplights, and body
lights clean and free of snow and ice. Use defroster and windshield
wipers to keep windshield free of snow and ice.
