• Before driving, clear all snow and ice from the windshield, rear window, outside rear view mirrors, and all side windows.
• Clear all snow and ice from the hood and air inlet in the cowl grill to improve heater and defroster efficiency and to reduce the probability of fogging up the inside of the windshield.
