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. This warning light will come on to let you know if there's a problem with your traction control system. 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. See Traction Control System (TCS) Warning Light on page 3-66. When this warning light 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. Notice: Do not repeatedly brake or accelerate heavily when the TCS is off. You could damage your vehicle's driveline. When the TCS is switched off on AWD and STS-V vehicles, you may still feel the system working. This is normal and necessary with the AWD hardware on your vehicle. Traction Control System (TCS) Your vehicle has a traction control system that limits wheel spin. This is especially useful in slippery road conditions. On a rear-wheel-drive vehicle, the system operates if it senses that one or both of the rear wheels are spinning or beginning to lose traction. On an All-Wheel-Drive (AWD) vehicle, the system will operate if it senses that any of the wheels are spinning or beginning to lose traction. When this happens, the system brakes the spinning wheel(s) and/or reduces engine power to limit wheel spin. You may feel or hear the system working, but this is normal. 4-9
