12. Adjust the heater to remove ice and dew from the windows.
Set the temperature as you like it when you drive. Remember not to drive until you have removed all the dew and frost on the routes. Mirrors and rear windows are often defrosted using heat. There should be a button for that.
13. Check that the sound- and light horn works.
To test the sound horn, press in the middle of the steering wheel. To check the light horn, pull the left lever towards you and release (same lever as the turn signals). Remember that reckless use of sound or lighting is prohibited.
14. Check that the airbag warning light works.
Turn on the ignition, the lamp should then switch on and automatically switch off after a few seconds.
15. Who should not be seated in front of an airbag?
Children and short people can be injured if the airbag deploys. Especially if the child sits back-to-front in their own chair. They will be squeezed into the passenger seat.
16. Show engine oil fill location and check engine oil level
Open the hood and check. The oil should be between min and max. Check the level with the dipstick. Newer cars do not have a dipstick and the car checks the oil level itself. If the oil is low, a warning light will appear in the dashboard. If the lamp lights up red, the car must be stopped immediately. You can't drive to the nearest workshop either, as you risk damaging the engine.
Electric cars do not use oil.
