First, open the door slightly to let the moist air escape. Turn on the fan and direct it towards the windscreen. Don’t start the engine yet. In the meantime, scrape the windows of your shared car. Every Greenwheels car has a parking card inside. This card also works as an ice scraper!
You can only drive safely with good visibility. So make sure to clear the entire car of snow and ice: not just the windows, but also the bonnet, mirrors, roof and sides.
Keep the engine off while removing snow and ice. The engine hardly warms up when the car is stationary. Warm up yourself and the car once you start driving.
