Instruments and controls / Warning and indicator
Even if the EBD system fails, the conventional 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 vehicle’ s motion may therefore become somewhat harder to control.
If the brake system warning light /, Vehicle Dynamics Control warning light and ABS warning light / illuminate simultaneously, take the following steps.
1. Stop the vehicle in the nearest safe, flat location.
2. Shut down the engine, apply the parking brake and then restart it.
3. Fully release the parking brake.
4. Even if all the warning lights do not come back on, the EBD system may have a possible malfunction. Drive carefully to the nearest SUBARU dealer and have the system inspected.
5. If all the warning lights stay illuminated or come back on after approximately 2 seconds, shut down the engine, apply the parking brake and check the brake fluid level.
. If the brake fluid level is not below the“ MIN” mark, the EBD system may be malfunctioning. Drive carefully to the nearest SUBARU dealer and have the system inspected.
