Starting and operating
Electronic Brake Force Dis-
tribution (EBD) system
The EBD system maximizes the effective-
ness of the brakes by allowing the rear
brakes to supply a greater proportion of
the braking force. It functions by adjusting
the distribution of braking force to the rear
wheels in accordance with the vehicle’s
loading condition and speed.
The EBD system is an integral part of the
ABS system and uses some of the ABS
system’s components to perform its func-
tion of optimizing the distribution of brak-
ing force. If any of the ABS components
used by the EBD function fails, the EBD
system also stops working.
When the EBD system is operating, you
may hear a chattering noise or feel a slight
vibration in the brake pedal. This is normal
and does not indicate a malfunction.
¢ Steps to take if EBD system
fails
If a malfunction occurs in the EBD system,
the system stops working and the brake
system warning light and ABS warning
light come on simultaneously.
The EBD system may be faulty if the brake
system warning light and ABS warning
light illuminate simultaneously during driv-
ing.
Even if the EBD system fails, the conven-
tional braking system will still function.
However, the rear wheels will be more
prone to locking when the brakes are ap-
plied harder than usual and the vehicle’s
motion may therefore become somewhat
harder to control.
If the brake system warning light and ABS
warning light illuminate simultaneously,
take the following steps:
1. Stop the vehicle in the nearest safe, flat
place.
2. Shut down the engine, then restart it.
3. Release the parking brake. If both
warning lights go out, the EBD system
may be faulty. Drive carefully to the near-
est Saab dealer and have the system in-
spected.
4. If both warning lights come on again
and stay illuminated after the engine has
been restarted, shut down the engine
again, apply the parking brake, and check
the brake fluid level.
5. If the brake fluid level is not below the
“MIN” mark, the EBD system may be
faulty. Drive carefully to the nearest Saab
dealer and have the system inspected.
6. If the brake fluid level is below the
“MIN” mark, DO NOT drive the vehicle. In-
stead, have the vehicle towed to the near-
est Saab dealer for repair.
