Avoid shifting down abruptly. Such behavior can cause the wheel to lock, possibly leading to loss of vehicle control. Avoid locking the front wheels because that can lead to a loss of steering control. When braking with a vehicle not equipped with an Anti-Lock Brake System (ABS), press the brake pedal repeatedly at short intervals to prevent the wheels from locking. Then apply the brakes softly to bring the vehicle to a stop. An ABS enhances your vehicle's braking performance on snowy and icy roads. Refer to the "ABS (Anti-Lock Brake System)" in this chapter for information on braking on slippery surfaces in ABS equipped vehicle. n Wiper operation when snowing Before driving in cold weather, make sure the wiper blades are not frozen to the windshield or rear window. If the wiper blades are frozen to the windshield or rear window, use the defroster with the airflow control dial in the " " position and the temperature control dial turned fully to the right until the wiper blades are completely thawed out. To thaw out the rear wiper blade, use the rear window defogger. When driving in snow, if frozen snow starts to stick on the surface of the windshield despite wiper operation, use the defroster with the airflow control dial in " " and the temperature control dial turned fully to the right. After the windshield gets warmed enough to melt the frozen snow on it, wash it away using the windshield washer. Snow stuck on the wiper arm prevents the wiper from working effectively. If snow is stuck on the wiper arm, pull off the road to a safe place, then remove it. If you stop the car at the side of the road, use the hazard warning flasher to alert other drivers. We recommend use of non-freezing type wiper blades during the seasons you could have snow and sub-zero temperature. 7-44
