Winter program

The winter program is activated/deactivated automatically. A defensive shift characteristics and shift stabilization are provided on the basis of the respective basic map (avoiding pendulum shifts). This enables the highest possible stability and driving safety on wet or icy roadways. Stable gear positions support running gear interventions of automatic stability control (ASC) or dynamic stability control (DSC) in an optimum way. Downshift requests that result in tensile force and could lead to spinning wheels are suppressed. This exempts downshift requests explicitly requested by the driver. As long as the winter program is active, functions that influence the stability of the vehicle are only effective to an extent where instability is avoided or they are completely switched off.
