The RANGE display shows how far the computerthinks you can travel with the fuel that is in your tank. The computer does know what not driving conditions will be like for the rest of your trip, so the range is estimated based on your recent fuel economy. Therefore, your range reading may change as your driving habits change. (Going from city to highway driving mayincrease 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, however, so it will read LO when your vehicleis brand new (under 25 miles). It may also show LO if your battery has been disconnected.
