Bonnet contact switch
The 2 bonnet contact switches (Hall sensors) notify the SMG control unit of whether the bonnet is open or
closed.
The gear is cancelled when the bonnet is open to prevent the vehicle from pulling away unintentionally in the
workshop. (e.g. The engine is running at idle-speed. A drive position is selected. The accelerator pedal is in the
idle position. The clutch is disengaged.
The accelerator pedal could be unintentionally pressed whilst work is being carried out in the engine
compartment.)
The bonnet contact switches are permanently monitored whilst the vehicle is being driven. If a bonnet contact
switch should fail, an "open bonnet" will detected when the vehicle is stationary. The gear indicator on the LCD
display flashes.
The bonnet contact switches are fitted in the two bonnet locks.
