EBD (electronic brake forcedistribution)
Observe the "Important safety notes"
section.
EBD monitors and controls the brake pressure on the rear wheels to improve driving stability while braking.
WARNING 
If EBD has malfunctioned, the braking system
remains available with full brake boosting
effect. However, the rear wheels can still lock,
e.g. under full braking. This could cause you
to lose control of your vehicle and cause an
accident. You should therefore adapt your
driving style to the different handling
characteristics.
► Observe the notes on warning and indicator lamps as well as display messages.
