Antilock Brake System (ABS) Your vehicle has the Antilock Brake System (ABS), an advanced electronic braking system that will help prevent a braking skid. When you start the engine and 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 a little. This is normal. If there is a problem with ABS, this warning light will stay on. See Antilock Brake System (ABS) Warning Light on page 3-38. 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. 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. Using ABS Do not pump the brakes. Just hold the brake pedal down firmly and let antilock work for you. You might hear the antilock pump or motor operate, and feel the brake pedal pulsate, but this is normal. 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 wheel. Braking in Emergencies With ABS, you can steer and brake at the same time. In many emergencies, steering can help you more than even the very best braking. 4-5
