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. TCS may operate on dry roads under some conditions. When this happens, you may notice a reduction in acceleration or a pumping sound. This is normal and does not mean there's a problem with your vehicle. Examples of these conditions include hard acceleration in a turn, an abrupt upshift or downshift of the transmission or driving on rough roads. If your vehicle is in cruise control when the TCS begins to limit wheel spin, the cruise control will automatically disengage. When road conditions allow you to safely use it again, you may re-engage the cruise control. See Cruise Control on page 3-12. If your vehicle has a Driver information Center (DIC), a SERVICE TRACTION CONTROL message will appear when a Traction Control System or Antilock Brake System problem has been detected and the vehicle needs service. See DIC Warnings and Messages on page 3-56. When this message is on, the system will not limit wheel spin. Adjust your driving accordingly. The traction control system automatically comes on whenever you start your vehicle. To limit wheel spin, especially in slippery road conditions, you should always leave the system on. But you can turn the traction control system off if you ever need to. 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. Traction Control System (TCS) Your vehicle has 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 any of the wheels are spinning or beginning to lose traction. When this happens, the system applies the brakes to limit wheel spin and also reduces engine power. You may feel or hear the system working, but this is normal. 4-5
