Using Anti-Lock Do not pump the brakes. Just hold the brake pedal down firmly and let anti-lock work for you. You may hear the anti-lock pump or motor operate, and feel the brake pedal pulsate, but this is normal. Traction control helps you to keep control of the vehicle and reminds you to match your speed to the road conditions. You may feel or hear the system working, but this is normal. The TCS is automatically turned on whenever the ignition is turned from off to on. A Low Traction message is displayed on the trip computer, indicating traction control is limiting wheel spin, until the MODE button on the trip computer is pressed. The message then goes back to the original trip computer display with a small low traction symbol on the left. The symbol will remain as long as the low traction situation exists. To limit wheel spin, especially in slippery road conditions, you should always leave the TCS on. But you can turn the system off if you prefer. Braking in Emergencies With anti-lock brakes, 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 one or both of the rear wheels are spinning or beginning to lose traction. When this happens, the system reduces engine power and applies the brakes, as necessary. 4-8
