then go out after starting off. If it does not go out after starting off or if it lights up while
riding, this indicates a fault in the ABS system. In this case, the ABS is no longer enabled
and the wheels may lock during braking. The brake system itself stays functional; only ABS
control is not available.
The ABS warning lamp may also light up if the rotating speeds of the front and rear wheels
differ greatly under extreme riding conditions, for example when making wheelies or if the
rear wheel spins. This causes the ABS to switch off.
To reenable the ABS, the vehicle must be stopped and the ignition switched off. The ABS
is reenabled when the vehicle is switched on again. The ABS warning lamp goes out when
you start off.
Button can be used to switch ABS off manually (see Starting).
