Configuring the prewarning

After the warning function is switched on, the following can be set via the iDrive:

  • The prewarning can be switched on/off.
  • The time of the prewarning can be set.

These settings have no effect on the time of the warning from the Active Cruise Control* that prompts the driver to intervene or brake.
