Starting and driving
Brake system
After the engine has started and reached a
speed of about 20 km/h, a short self-test can
be both heard and felt. When the ABS
system functions, you can hear and feel
pulses in the brake pedal. This is completely
normal.
NOTE! You must depress the brake pedal
fully to take maximum advantage of the ABS
system. Do not release the pedal when you
hear and feel the ABS pulses. Practice brak-
ing with the ABS system at a suitable spot
such as a track to practice skidding.
The ABS symbol lights up:
• For approximately two seconds during the
system test when the car is started.
• If the ABS system has shut down due to a
fault.
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 availa-
ble. Pulses will be heard and felt through the
brake pedal when the system regulates brake
force.
Emergency Brake Assistance – EBA
The Emergency Brake Assistance function
(EBA) is integrated in the DSTC system and
is designed to provide immediate maximum
brake force whenever rapid braking is neces-
sary. 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. Continue braking without
releasing the brake pedal. The EBA function
disengages when the pressure on the brake
pedal is released.
WARNING!
If the BRAKE and ABS warning symbols
are lit at the same time, a fault may have
occurred in the brake system. 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.
