The ESC is switched on automatically when the engine is started.
The ESC operates in several levels. Depending on which level is selected, the stabilising function of the ESC is restricted or switched off, and the Audi A4 is stabilised to a greater or lesser degree.
In the following special situations, it may be advisable to switch on the sport mode (Saloon/Avant) or off-road mode (allroad) to allow a certain amount of wheelspin:
  • Rocking the car backwards and forwards to free it
  • Driving in deep snow or on loose surfaces
  • Driving with snow chains
  • allroad: Driving on rough terrain when much of the car's weight is lifted off the wheels (axle articulation)
  • allroad: Braking on unsurfaced tracks when driving downhill
