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. Traction Control System (TCS) Your vehicle may have a Traction Control System (TCS) that limits wheel spin. This is especially useful in slippery road conditions. The system operates only if it senses that one or both of the rear wheels are spinning or beginning to lose traction. When this happens, the system reduces engine power and may also upshift the transmission to limit wheel spin. You may feel or hear the system working, but this is normal. The TCS warning light will also flash to indicate that the traction control system is active. This warning light will come on to let you know if there is a problem with your traction control system. Using ABS Do not pump the brakes. Just hold the brake pedal down firmly and let antilock work for you. You might feel the brakes vibrate or notice some noise, but this is normal. 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. The light will also illuminate when the traction control system is turned off, and a TRAC OFF message will also appear on the Driver Information Center (DIC). See DIC Warnings and Messages on page 3-42 for more information. 4-5
