Your vehicle might have the Antilock Brake System (ABS), an advanced electronic braking system that will help prevent a braking skid.

If your vehicle has ABS, this warning light on the instrument panel will come on briefly when you start your vehicle.

When you start the engine, or when you begin to drive away, ABS will check itself. You might hear a momentary motor or clicking noise while this test is going on, and you might even notice that the brake pedal moves or pulses a little. This is normal.

If there is a problem with ABS, the antilock brake system warning light will stay on. See Antilock Brake System (ABS) Warning Light .

Let us say the road is wet and you are driving safely. Suddenly, an animal jumps out in front of you. You slam on the brakes and continue braking. Here is what happens with ABS:

A computer senses that wheels are slowing down. If one of the wheels is about to stop rolling, the computer will separately work the brakes at each front wheel and at both rear wheels.

ABS can change the brake pressure faster than any driver could. The computer is programmed to make the most of available tire and road conditions. This can help you steer around the obstacle while braking hard.

As you brake, the computer keeps receiving updates on wheel speed and controls braking pressure accordingly.

If your vehicle has the vehicle stability control system, it includes a brake assist system which provides more powerful braking during a sudden, hard brake application. See "Vehicle Stability Control System" under Traction Control System (TCS) .

Remember: ABS does not change the time you need to get your foot up to the brake pedal or always decrease stopping distance. If you get too close to the vehicle in front of you, you will not have time to apply the brakes if that vehicle suddenly slows or stops. Always leave enough room up ahead to stop, even though you have ABS.

Do not pump the brakes. Just hold the brake pedal down firmly and let antilock work for you. You might feel a slight brake pedal pulsation or notice some noise, but this is normal.
