9-32 Driving and Operating If the compressor runs often for longer than one minute within the same trip and the vehicle remains low in the rear, see your dealer for service. If the vehicle is not used for several weeks, the rear of the vehicle may look low. When the engine is started, the vehicle will return to the proper height. If a weight-distributing hitch is being used, it is recommended to allow the air springs to inflate, thereby leveling the vehicle prior to adjusting the hitch. Cruise Control { Warning Cruise control can be dangerous where you cannot drive safely at a steady speed. 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. 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). If the brakes are applied, the cruise control disengages. If the Traction Control/Electronic Stability Control system begins to limit wheel spin while using cruise control, the cruise control automatically disengages. See Traction Control/Electronic Stability Control on page 9-29. If a collision alert occurs when cruise control is activated, cruise control is disengaged. See Forward Collision Alert (FCA) System on page 9-49. When road conditions allow the cruise control to be safely used, you can apply the cruise control again.
