9-34 Driving and Operating Adding non-dealer accessories can affect the vehicle's performance. See Accessories and Modifications on page 10‑3 for more information. Cruise Control { WARNING Cruise control can be dangerous where you cannot drive safely at a steady speed. So, do not use the cruise control on winding roads or in heavy traffic. Cruise control can be dangerous on slippery roads. On such roads, fast changes in tire traction can cause excessive wheel slip, and you could lose control. Do not use cruise control on slippery roads. For vehicles with cruise control, a speed of about 40 km/h (25 mph) or more can be maintained without keeping your foot on the accelerator. Cruise control does not work at speeds below about 40 km/h (25 mph). When the brakes are applied, cruise control is turned off. Locking Rear Axle Vehicles with a locking rear axle can give more traction on snow, mud, ice, sand, or gravel. It works like a standard axle most of the time, but when traction is low, this feature will allow the rear wheel with the most traction to move the vehicle. If the vehicle has StabiliTrak and the system begins to limit wheel spin, cruise control will automatically disengage. See StabiliTrak® System on page 9‑32. When road conditions allow the cruise control to be safely used again, it can be turned back on. I (On/Off): Press to turn the system on or off. The indicator light is on when cruise control is on and turns off when cruise control is off.
