BMW 7 Series: Safety Information For Working On Vehicles With Automatic Engine
Start-Stop Function (MSA)
WARNING: If the engine hood/bonnet contact is pulled upwards (workshop
mode),
the information "switch closed" is output. The automatic engine start-stop
function is active.
An automatic engine start is possible.
Observe safety precautions when working on MSA vehicles.
Before carrying out practical work on the engine, always ensure that the MSA
functionality is deactivated so as
to prevent automatic engine starting while work is being carried out in the
engine compartment.
MSA function is deactivated by
- Deactivate MSA by means of button (1) in passenger compartment
- Open seat belt buckle and driver's door
