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. See Traction Control System (TCS) Warning Light on page 3-65. When this warning light is on, the system will not limit wheel spin. Adjust your driving accordingly. The Traction Control System (TCS) 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 TCS 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 hardware on your vehicle. You should turn the system off if your vehicle ever gets stuck in sand, mud or snow and rocking the vehicle is required. See Rocking Your Vehicle to Get It Out on page 4-26 and If Your Vehicle is Stuck in Sand, Mud, Ice, or Snow on page 4-25 for more information. See also Winter Driving on page 4-22 for information on using TCS when driving in snowy or icy conditions. 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. This warning light will come on to let you know if there is a problem with your traction control system. 4-6
