StabiliTrak® comes on automatically whenever you start your vehicle. However, when the transfer case is placed in Four-Wheel-Low Lock mode, StabiliTrak® is automatically disabled. See Full-Time Four-Wheel Drive on page 2-27 for more information. To help assist you with directional control of the vehicle, you should always leave the system on. You can turn StabiliTrak® off if you ever need to using the TC (traction control) on/off button. If you press and hold the TC button for five seconds, the StabiliTrak® system and the traction control system will turn off. When this is done, the STAB SYS OFF message will be displayed on the DIC. Press the TC button again to turn StabiliTrak® back on. See Traction Control System (TCS) on page 4-5. If your vehicle is in cruise control when the StabiliTrak® activates, the cruise control will automatically disengage. When road conditions allow you to safely use it again, you may reengage the cruise control. See Cruise Control on page 3-11 for more information. Steering Tips It is important to take curves at a reasonable speed. A lot of the "driver lost control" accidents mentioned on the news happen on curves. Here is 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 is no traction, inertia will keep the vehicle going in the same direction. If you have ever tried to steer a vehicle on wet ice, you will understand this. The traction you can get in a curve depends on the condition of the tires and the road surface, the angle at which the curve is banked, and your speed. While you are in a curve, speed is the one factor you can control. Suppose you are 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 Control System (TCS) on page 4-5 and StabiliTrak® System on page 4-7. 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. 4-8
