06 Starting and driving
Brake system
Anti-lock braking system (ABS)
The anti-lock braking system
(ABS) prevents the wheels from
locking up during braking.
This means the ability to steer is
maintained and it is easier to swerve to avoid a
hazard for example.
After the engine has been started, the ABS will
perform a brief self-test at a speed of
about 20 km/h. This can be felt and heard as
pulses in the brake pedal.
To get the most out of the ABS:
1. Depress the brake pedal with full force.
Pulses will be felt.
2. Steer the car in the direction of travel. Do
not release the pressure on the pedal.
Practice braking with the ABS system in a traf-
06
fic-free area and in different weather condi-
tions.
The ABS symbol illuminates for two seconds if
there was a fault in the ABS system when the
engine was last running.

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 workshop and
have the brake system checked - an author-
ised Volvo workshop is recommended.
If the brake fluid is under the MIN level in the
brake fluid reservoir, do not drive further
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.
