Notice: If the StabiliTrak® light comes on due to heavy braking and/or because the traction control system has been continuously active, do not allow the wheel(s) of one axle to spin excessively. If you do, you may be causing damage to the transfer case. This could lead to costly repairs not covered by your warranty. Notice: If you allow the wheel(s) of one axle to spin excessively while the StabiliTrak®, ABS and brake warning lights and the SERVICE STABILITRAK message are displayed, you could damage the transfer case. The repairs would not be covered by your warranty. Reduce engine power and do not spin the wheel(s) excessively while these lights and this message are displayed. StabiliTrak® 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 StabiliTrak® light will blink, and the cruise control will automatically disengage. When road conditions allow, you may re-engage the cruise control. See Cruise Control on page 159. StabiliTrak® will turn off automatically if a problem is detected in the system. The StabiliTrak® light will come on and SERVICE STABILITRAK will be displayed on the DIC. For vehicles without a DIC, the StabiliTrak® light and the StabiliTrak® service light will both come on. If the SERVICE STABILITRAK message (or StabiliTrak® service light) does not clear itself after restarting the vehicle, you should see your dealer for service. Adding non-GM accessories can affect your vehicle's performance. See Accessories and Modifications on page 356 for more information. All-Wheel Drive (AWD) System Your vehicle may have this feature. There is no lever or switch to engage or disengage the front axle. It is fully automatic and adjusts as needed for road conditions. Your vehicle has an active transfer case allowing two-wheel-drive operation on dry roads. The transfer case will shift automatically into all-wheel drive on slippery surfaces. You may feel an extra shift when the all-wheel drive engages. 293
