distribution)
i Observe the "Important safety notes"
section ( Y page 69).
EBD monitors and controls the brake
pressure on the rear wheels to improve
driving stability while braking.
G 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

accident. You should therefore adapt your
driving style to the different handling
characteristics.
