Warning Lights and Gauges Your distance to empty may change faster or slower than actual distance traveled because your fuel economy varies with changing driving conditions. The fuel computer will automatically warn you when your distance to empty is low. When your distance to empty reaches 50 miles (80 km), 25 miles (40 km) and 10 miles (20 km), the fuel computer will automatically select DISTANCE TO EMPTY, flash the number for five seconds, and sound a one second chime. If the Distance to Empty function displays CO or CS, you must have the fuel indication system serviced. Turn your ignition to OFF while fueling to obtain an accurate distance to empty reading. If you do not turn your ignition off, the fuel computer will not display the new distance to empty immediately, but will slowly increase to the correct value. AVERAGE SPEED Your average speed is the average speed your vehicle has traveled while the ignition was ON since the last reset. To display your average speed, press SELECT until the pointer is at AVERAGE SPEED. Press the RESET button when AVERAGE SPEED is selected to reset the average speed. You may want to use this feature to see what your average speed is during daily driving or on a long trip. 101
