1996 Ford Ranger Owner's Manual - Page 95

Steering Column Controls RWARNING Do not use the speed control in heavy traffic or on roads that are winding, slippery, or unpaved. In mountainous areas, at higher elevations, or when pulling a trailer, the speed control may not be able to maintain the preset speed with the transmission in j (Overdrive). If your vehicle comes with a 5-speed manual transmission, you may prefer to drive in 4 (Fourth) gear, in mountainous areas or at high altitudes, to improve speed control performance. In order to downshift (with a manual transmission) with the speed control operating, you must press either the brake or clutch pedal long enough to disengage the speed control. Wait a second before depressing the clutch again and making the shift so that the speed control can fully return to the idle position. RWARNING Do not shift the transmission into N (Neutral) with the speed control on. To maintain a preset speed under the above conditions, with electronically controlled transmissions - press the Transmission Control Switch (TCS). The indicator light will turn on and illuminate the words "O/D OFF." This will cancel "Overdrive." You can press the Transmission Control Switch (TCS) on or off at any speed. For the best fuel economy during normal driving conditions, press the Transmission Control Switch (TCS) to turn off the light. This allows overdrive operation. 95
