How do I know whether my vehicle has ABS?
  1) Read your owner's manual.
  2) Check your instrument panel for an amber ABS indicator light after you turn on the ignition.
  3) When you buy, lease or rent, ask your dealer or rental car company or your service technician.

How do I know if the ABS system is working?
    In many vehicles, you may experience a rapid pulsation of the brake pedal. It may feel like the brakes pedal is pushing back at you. Sometimes the pedal could suddenly drop. Also, the valves in the ABS controller may make a noise that sounds like grinding or buzzing. In some cars you may feel a slight vibration.

Do I need to change the way I use my brakes?
    You should not pump your brakes if you have ABS. Just hold your foot firmly on the brake pedal and remember to steer the car normally. Try some stops in an empty parking lot, but keep in mind that ABS systems are speed sensitive, and will not activate at very slow speeds.

Do ABS-equipped cars stop shorter?
    ABS is designed to help the driver maintain control of the vehicle during emergency braking, not make the cars stop shorter. ABS may shorten stopping distances on wet or slippery roads, and many systems will shorten stopping distances on dry roads. On very soft surfaces, like loose gravel or unpacked snow, an ABS system may actually lengthen stopping distances, but can provide a safer, controlled stop.

Are all antilock systems the same?
    They are all very similar in the way they control brake pressure, but some systems are designed to keep only the rear wheels from locking. These rear wheel anti-lock (RWAL) systems are found on pickups and sport-utility vehicles. Rear-wheel ABS keeps your vehicle from spinning out of control. All other ABS systems are designed to keep all four wheels from locking.
