EBD (Electronic Brake-force Distribution)
EBD is an integrated part of the ABS system. EBD regulates the hydraulic pressure to the rear brakes to
help provide optimal braking capacity.
If the BRAKE and ABS warning lights come on at the same time, this could indicate a fault in the brake
system. If the brake fluid level is above the MIN mark, drive carefully to an authorized Volvo retailer
and have the brake system inspected.
If the fluid level is below the MIN mark in the reservoir, DO NOT DRIVE. Have the car towed to an
authorized Volvo retailer and have the brake system inspected.
Stability and Traction Control (STC) - option on certain models
The STC-system is designed to help reduce wheel spin by limiting power to the drive wheels if they
begin to loose traction at speeds over 25 mph. At speeds over 25 mph, the STC system monitors and
compares all four wheels. If one of the drive (front) wheels shows any tendency to slip, such as when
driving on slippery roads, the difference in speed is immediately detected. This triggers a signal to the
engine management system, which will reduce engine torque (by reducing fuel) until the differential is
corrected. This torque reduction is handled in stages, and reaction time is extremely fast.
The symbol will flash when STC is actively regulating power to the drive wheels. Normal power may
be reduced at this time. This is normal as power is momentarily reduced to help keep the drive wheels
from losing traction and spinning.
The STC indicator light () will come on:
· When the car is started, for approximately 2 seconds, as the system performs a self-diagnostic test.
