7-22 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 illuminate simultaneously.

The EBD system may be malfuntioning if

the brake system warning light and ABS

warning light illuminate simultaneously

during driving.

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

applied harder than usual and the vehi-

cle’s motion may therefore become some-

what harder to control.

If the brake system warning light and ABS

warning light illuminate si multaneously,

take the following steps:

1. Stop the vehicle in the nearest safe,

flat place.

2. Shut down the engine, apply the

parking brake, and then restart it.

3. Release the parking brake. If both

warning lights turn off, the EBD system

may be malfuntioning.

Drive carefully to the nearest SUBARU

dealer and have the system inspected.

4. If both warning lights illuminate again

and remain 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

malfuntioning. Drive carefully to the near-

est SUBARU dealer and have the system

inspected.

6. If the brake fluid level is below the

“MIN” mark, DO NOT drive the vehicle.

Instead, have the vehicle towed to the

nearest SUBARU dealer for repair.

WARNING

. Driving with the br ake system

warning light illuminated is dan-

gerous. This indicates your brake
