Integrated Active Steering Special Function: Notes
Quite obviously, Active Steering systems must not be capable of being switched on or off by the driver.
In the case of Integrated Active Steering, there is a special feature in that regard because if snow chains are fitted to the rear wheels, Active Steering of the rear wheels must be disabled.
When snow chains are fitted, the rear-wheel steering is deactivated in order to ensure that the wheels are always free to rotate.
Automatic snow-chain detection assists the driver and indicates the detected status on the Control Display. This does not remove the responsibility for manually changing the setting.
When show chains are used, the setting on the iDrive Settings menu must be changed to "Show chains fitted".
If the maximum speed of 50 kph (31mph) for driving with snow chains is exceeded, the rear-wheel steering is reactivated regardless of the "Snow chains fitted" setting.
