RANGE Display This display shows how far the computer thinks you can go with the fuel thatis inyour tank. The computer does not know what driving conditions will be like for therest of your trip, so the range is estimated based on your recent fuel economy. Therefore, your range reading may change as your driving habitschange (going from city to highway driving may increase the range reading). If the range display shows"Lo",you should stop forfuel as soon as possible. Your computer needs enough data for the "RANGE" reading to work. It will read "Lo" for a while when your vehicle is brand new (under 25 miles). Also, it may show "Lo" for a whileif your battery has been disconnected. 139
