Mitsubishi Lancer Owners Manual
For cold and snowy weatherMaintenance / For cold and snowy weather
The ventilation slots in front of the windscreen should be kept clear of leaves or brushed clear after heavy snowfall, so that the operation of the heating and ventilation systems will not be impaired.
To prevent freezing of the weatherstripping on the doors, bonnet, etc., they should be treated with silicone grease or spray.
It is a good idea to carry a shovel or a short-handled spade in the vehicle during the winter so that you can clear away snow if you get stranded. A small hand-brush for sweeping snow off the vehicle and a plastic scraper for the windscreen and rear window are also useful.
