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. Braking in Emergencies At some time, nearly every driver gets into a situation that requires hard braking. If you have ABS, you can steer and brake at the same time. However, if you do not have ABS, your first reaction - to hit the brake pedal hard and hold it down - might be the wrong thing to do. Your wheels can stop rolling. Once they do, the vehicle cannot respond to your steering. Momentum will carry it in whatever direction it was headed when the wheels stopped rolling. That could be off the road, into the very thing you were trying to avoid, or into traffic. If you do not have ABS, use a "squeeze" braking technique. This will give you maximum braking while maintaining steering control. You can do this by pushing on the brake pedal with steadily increasing pressure. In an emergency, you will probably want to squeeze the brakes hard without locking the wheels. If you hear or feel the wheels sliding, ease off the brake pedal. This will help you retain steering control. If you do have ABS, it is different. See Antilock Brake System (ABS) on page 4-4. In many emergencies, steering can help you more than even the very best braking. Using 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. 4-5
