With Sport mode selected, interventions from the system are reduced and the car is allowed to skid more and greater control than normal is thus transferred to the driver.
When Sport mode is selected, the function can be considered as deactivated, despite the function continuing to help the driver in many cases.
Note
With Sport mode selected, trailer stability assist (TSA) (TSA2) is deactivated.
Sport mode also provides more traction even if the car has become bogged down or is driving on a loose surface, such as in sand or deep snow.
