Winter driving 421
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 selection in“” and the temperature set for maximum warmth. After the windshield gets warmed enough to melt the frozen snow on it, wash it away using the windshield washer. Refer to“ Windshield washer” FP243.
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 vehicle at road side, use the hazard warning flasher to alert other drivers. Refer to“ Hazard warning flasher” FP166.
We recommend use of non-freezing type wiper blades( winter blades) during the seasons you could have snow and freezing temperatures. Blades of this type give superior wiping performance in snowy conditions. Be sure to use blades that are suitable for your vehicle.
CAUTION
During high-speed driving, nonfreezing type wiper blades may not perform as well as standard wiper blades. If this happens, reduce the vehicle speed.
NOTE
When the season requiring non-freezing type wiper blades is over, replace them with standard wiper blades.
& Corrosion protection
Refer to“ Corrosion protection” FP470.
