Brake system
Electronic brake force distribution
system – EBD
The Electronic Brakeforce Distribution system
(EBD) 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 will be heard
and felt through the brake pedal when the sys-
tem regulates brake force.
WARNING
If the BRAKE and ABS warning symbols illu-
minate at the same time, there may be a
fault in the brake system. If the level in the
brake fluid reservoir is normal at this stage,
drive carefully to the nearest authorised
Volvo workshop and have the brake system
checked.
If the brake fluid is under the MIN level in the
brake fluid reservoir, do not drive further
06
before topping up the brake fluid.
The reason for the loss of brake fluid must
be investigated.

Emergency Brake Assistance – EBA
(Emergency Brake Assistance) For sudden
braking, full-strength braking is provided
instantaneously. The EBA function senses
when heavy braking is underway by registering
how quickly the brake pedal is depressed.
Continue braking without easing off on the
brake pedal. The function is suspended when
the pressure on the brake pedal eases. This
function is always active. It cannot be disen-
gaged.
NOTE
When EBA is activated the brake pedal low-
ers slightly more than usual, depress (hold)
the brake pedal as long as necessary. If the
brake pedal is released then all braking
ceases.
