In an older (2020) Owner’s Manual, pages 28/29:
“Overseer Switch (Automatic Vehicles Only)
WARNING Do not disable the overseer for driving on public roads.
WARNING The Overseer system is not a driver aid, stability, or traction
control system.
The overseer is a safety feature that detects locking of the rear wheels. In such
an event the overseer will place the gearbox into neutral. This feature can be
deactivated at the driver’s risk if potential rear wheel lock-up is considered
acceptable. This is not advisable on public roads under any circumstance.
With the ignition on, or engine running, pressing the overseer button for 3
seconds will disable the rear wheel lockup detection. When the overseer is
disabled, the amber overseer icon (OS) will display in the Driver Information
Panel. The overseer automatically re-engages after the ignition is switched off.“
