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.
If both the BRAKE and ABS
ning symbols are lit, 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 nor-
mal, 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 function is
integrated in the DSTC system.
The system is designed to provide maximum
brake force immediately whenever rapid
braking is necessary. The system detects the
need for heavier braking by registering how
quickly the brake pedal is applied.
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.
war- Continue braking without releasing the brake
pedal.
The EBA function disengages when the
pressure on the brake pedal is relieved.
