Driver Controls Note: The running boards may operate slower in cooler temperatures. In adverse conditions, debris such as mud, dirt, and salt may become trapped in the running board mechanism, possibly leading to unwanted noise. If this occurs, manually set the running boards to the deployed position and flush the system (in particular the front and rear hinge arms) with a high-pressure car wash wand. Note: Do not use the running boards, front and rear hinge assemblies, running board motors, or the running board under body mounts to lift the vehicle when jacking. Please utilize proper jacking points. Refer to Changing the tires in the Roadside Emergencies chapter. WARNING: In extreme climates, excessive ice buildup may occur, causing the running boards not to deploy. Be sure that the running boards have deployed, and have finished moving before attempting to step on them. Note: The running boards will resume normal function once the blockage is cleared. WARNING: Turn off the running boards before jacking or placing any object under the vehicle. Never place your hand between the extended running board and the vehicle. A moving running board may cause injury. SPEED CONTROL (IF EQUIPPED) With speed control set, you can maintain a set speed without keeping your foot on the accelerator pedal. WARNING: Do not use the speed control in heavy traffic or on roads that are winding, slippery or unpaved. 137 2010 Expedition (exd) Owners Guide, 3rd Printing USA (fus)
