General notes

WARNING
If the vehicle becomes trapped in snow, ensure that snow is kept away from the exhaust pipe and from around the vehicle as long as the engine is running. Otherwise, poisonous carbon monoxide (CO) may enter the vehicle, resulting in loss of consciousness and even death.
To assure sufficient fresh air ventilation, open a window slightly on the side of the vehicle not facing the wind.

At the onset of winter, have your vehicle winterproofed at a qualified specialist workshop, e.g. at an authorized Mercedes-Benz Center.
Observe the notes in the "Winter operation" section.
