Brake system/ABS/EBD
Electronic Brakeforce
Distribution (EBD)
The EBD system (Electronic Brakeforce
Distribution) is an integrated part of the ABS
system. The EBD system controls the brake
force to the rear wheels so that the best possible
braking force is always available. Pulses in the
brake pedal can be felt and heard as the system
controls the brake force.
WARNING!
If both the BRAKE and ABS
warning symbols are lit up there is a risk
that the rear end will have a tendency to
slide during heavy braking. If the level in
the brake fluid reservoir is normal, drive
carefully to the nearest authorised Volvo
workshop to have the brake system
checked.
If the level of brake fluid in the reservoir is
below the MIN mark, the car should not be
driven until the brake fluid has been topped
up. The reason for the loss of brake fluid
must be investigated.

Emergency Brake Assistance (EBA)
The Emergency Brake Assistance (EBA)
function is integrated in the DSTC system and
is designed to provide immediate maximum
brake force whenever rapid braking is necessa-
ry. The system detects the need for heavier
braking by registering how quickly the brake
pedal is depressed.
The EBA function is active at all speeds. For
safety reasons, it cannot be switched off.
When the EBA function is activated, the brake
pedal sinks while maximum braking force is
applied. Continue braking without releasing the
brake pedal. The EBA function disengages
when the pressure on the brake pedal is
released.
