Good to know(4_37):

If the „Sailing function“ is activated, the drive train is decoupled from the engine while
driving. After switching off the „Sailing function“, the transmission automatically shifts
into the optimal gear.
The „Sailing function“ is only possible in driving mode „E+“ when actively releasing the
accelerator pedal without braking or when pressing the shift button „+“ for at least 0,3
sec. All pre conditions have to be fulfilled.
The most important premises for activation of KID+ are:
Drive program „E+“ selected,
A vehicle speed between 60 and 160 km/h,
No short-time-manual mode (KZM) enabled and
No SPEEDTRONIC/DISTRONIC active.
KID+ is deactivated when:
Pressing the accelerator pedal,
Pressing the brake pedal (braking torque >1.500Nm, heavy braking or light braking over a certain time period),
Pressing the shift buttons „+“ or „-“,
The vehicle speed is below 50 km/h or above 160 km/h or
When changing the driving mode.
