I now wanted to mount the original winter wheels and found that there is no jack in the vehicle. I asked the customer service department in Cologne why the new vehicles are generally delivered without jacks and received the following answer: So it is in Germany that we deliver a tire repair kit instead of a full replacement wheel or an emergency bike to the vehicle. To use the tire repair kit no jacks are needed. Against this background it is perhaps understandable that we no longer supply a jack anymore. Basically, the jacks supplied with vehicles are a breakdown tool, which should not be used regularly to change their own wheels. Because of the fact that it is a mechanical jack, it must be taken into account when actually changing the wheels, that neither escape nor slip the ground worry for a one-sided load. The risk that the load is too high when a day is used regularly is due to the fact that it is a mechanical jack to be used for the regular change of the wheels to be a hydraulic jack to be used by the car lifter.
