MDM Mode
This is the MDM Mode Indicator (M Dynamic Mode) text symbol. Quite simply, it refers to a drive mode available in one model, the M, from one Manufacturer, BMW. M Dynamic Mode makes it possible to “drive on a dry roadway with high longitudinal and transverse acceleration but with limited driving stability”. This is automotive tech speak for transferring near full control to the driver.

M Dynamic Mode is activated by pressing the stability control off button. This results in the illumination of both the MDM and the stability control OFF symbols. The use of MDM actually shuts off the stability control system. According to BMW, stability control will only be activated when the absolute limit of stability is reached. This is pretty much impossible to define.

BMW Symbols
This is a Vehicle Climate Preconditioner Indicator symbol. If a vehicle is so equipped, it can be heated or cooled in advance of driving. In warm weather, the ventilation system cools the passenger compartment by blowing air in from outside. The function cannot heat the passenger compartment, since this requires the vehicle to be running. The image is that of wavy lines or arrows rising from a line.
