The traction control system may activate on dry or rough roads or under conditions such as heavy acceleration while turning or abrupt upshifts/downshifts of the transmission. When this happens you may notice a reduction in acceleration, or may hear a noise or vibration. This is normal. If your vehicle is in cruise control when the system activates, the STABILITY SYS ACTIVE message will appear on the Driver Information Center and the cruise control will automatically disengage. When road conditions allow you to use cruise again, you may re-engage the cruise control. See "Cruise Control" under Turn SignaVMultifunction Lever on page 3-7 Stabilitrak@ may also turn off automatically if it determines that a problem exists with the system. If the problem does not clear itself after restarting the vehicle, you should see your dealer for service. Steering Tips Driving on Curves It's important to take curves at a reasonable speed. A lot of the "driver lost control" accidents mentioned on the news happen on curves. Here's why: Experienced driver or beginner, each of us is subject to the same laws of physics when driving on curves. The traction of the tires against the road surface makes it possible for the vehicle to change its path when you turn the front wheels. If there's no traction, inertia will keep the vehicle going in the same direction. If you've ever tried to steer a vehicle on wet ice, you'll understand this. The traction you can get in a curve depends on the condition of your tires and the road surface, the angle at which the curve is banked, and your speed. While you're in a curve, speed is the one factor you can control. Suppose you're steering through a sharp curve. Then you suddenly accelerate. Both control systems steering and acceleration - have to do their work where the tires meet the road. Adding the sudden acceleration can demand too much of those places. You can lose control. See Traction Assist System (TAS) on page 4-9. What should you do if this ever happens? Ease up on the accelerator pedal, steer the vehicle the way you want it to go, and slow down. Steering Power Steering If you lose power steering assist because the engine stops or the system is not functioning, you can steer but it will take much more effort. 4-14
