7-36 Starting and operating the system stops working and the brake system warning light and ABS warning light illuminate simultaneously. The EBD system may be malfunctioning if the brake system warning light and ABS warning light illuminate simultaneously during driving. 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 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, apply the parking brake and then restart it. 3. Release the parking brake. If both warning lights turn off, the EBD system may be malfunctioning. 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 malfunctioning. Drive carefully to the nearest 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. Vehicle Dynamics Control system (if equipped) WARNING Always use the utmost care in driving - overconfidence because you are driving with a Vehicle Dynamics Control system equipped vehicle could easily lead to a serious accident. WARNING . Driving with the brake system warning light illuminated is dangerous. This indicates your brake system may not be working properly. If the light remains illuminated, have the brakes inspected by a SUBARU dealer immediately. . If at all in doubt about whether the brakes are operating properly, do not drive the vehicle. Have your vehicle towed to the nearest SUBARU dealer for repair. CAUTION . Even if your vehicle is equipped with Vehicle Dynamics Control, winter tires or snow chains should be used when driving on snow-covered or icy roads; in addition, vehicle speed should be reduced considerably. Simply having a Vehicle Dynamics Control system does not guarantee that the vehicle will be able to avoid accidents in any situation. . Activation of the Vehicle Dynamics Control system is an indication that the road being travelled on has a slippery surface; since having Vehicle Dynamics Control is no guarantee
