tion (Y page 61). G
WARNING
If EBD has malfunctioned, the rear wheels can
still lock, e.g. under full braking. This increa-
ses the risk of skidding and an accident.
You should therefor eadapt your driving style
to the different handling characteristics. Have
the brak esystem checked at aqualified spe-
cialist workshop. Observe information regarding indicator and
warning lamps (Y
page 327) as well as dis-
play messages (Y page 293).
EBD monitors and controls the brake pres-
sure on the rear wheels to improve driving
stability while braking. ADAPTIVE BRAKE
ADAPTIVE BRAKE enhances braking safety
and offers increased braking comfort. In addi-
tion to the braking function, ADAPTIVE BRAKE
also has the HOLD function (Y page 211) and
