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.
