Subaru Legacy Owners Manual: ABS (Anti-lock Brake System)

Subaru Legacy Owners Manual / Starting and operating / ABS (Anti-lock Brake System)

WARNING Always use the utmost care in driving - overconfidence because you are driving with an ABS equipped vehicle could easily lead to a serious accident.


  •  The ABS does not always decrease stopping distance. You should always maintain a safe following distance from other vehicles.
  •  When driving on badly surfaced roads, gravel roads, icy road, or over deep newly fallen snow, stopping distances may be longer for a vehicle with the ABS than one without. When driving under these conditions, therefore, reduce your speed and leave ample distance from other vehicles.
  •  When you feel the ABS operating, you should maintain constant brake pedal pressure. Do not pump the brake pedal since doing so may defeat the operation of the ABS.

The ABS prevents the lock-up of wheels which may occur during sudden braking or braking on slippery road surfaces. This helps prevent the loss of steering control and directional stability caused by wheel lock-up.

When the ABS is operating, you may hear a chattering noise or feel a slight vibration in the brake pedal. This is normal when the ABS operates.

The ABS will not operate when the vehicle speed is below approximately 6 mph (10 km/h).

ABS self-check

You may feel a slight shock in the brake pedal and hear the operating noise of the ABS from the engine compartment just after the vehicle is started. This is caused by an automatic functional test of the ABS being carried out and does not indicate any abnormal condition.
