Driver Controls Note: • Vehicle speed may vary momentarily when driving up and down a steep hill. • If the vehicle speed increases above the set speed on a downhill, you may want to apply the brakes to reduce the speed. • If the vehicle speed decreases more than 10 mph (16 km/h) below your set speed on an uphill, your speed control will disengage. Resuming a set speed Press the RES (resume) control and release it. This will automatically return the vehicle to the previously set speed. Increasing speed while using speed control There are two ways to set a higher speed: • Press and hold the SET + control until you get to the desired speed, then release the control. You can also use the SET + control to operate the Tap-Up function. Press and release this control to increase the vehicle set speed in small amounts by 1 mph (1.6 km/h). • Use the accelerator pedal to get to the desired speed. When the vehicle reaches that speed press and release the SET + control. 110 2008 F-250/350/450/550 (f23) Owners Guide (post-2002-fmt) USA (fus)
