Maintenance and Specifications The advertised capacity is the amount of the indicated capacity and the empty reserve combined. Indicated capacity is the difference in the amount of fuel in a full tank and a tank when the fuel gauge indicates empty. Empty reserve is the small amount of fuel remaining in the fuel tank after the fuel gauge indicates empty. The amount of usable fuel in the empty reserve varies and should not be relied upon to increase driving range. When refueling your vehicle after the fuel gauge indicates empty, you might not be able to refuel the full amount of the advertised capacity of the fuel tank due to the empty reserve still present in the tank. For consistent results when filling the fuel tank: • Turn the engine/ignition switch to the off position prior to refueling, an error in the reading will result if the engine is left running. • Use the same filling rate setting (low - medium - high) each time the tank is filled. • Allow no more than 2 automatic click-offs when filling. • Always use fuel with the recommended octane rating. • Use a known quality gasoline, preferably a national brand. • Use the same side of the same pump and have the vehicle facing the same direction each time you fill up. • Have the vehicle loading and distribution the same every time. Your results will be most accurate if your filling method is consistent. Calculating fuel economy 1. Fill the tank and record the odometer reading. 2. Each time you fill up the tank, record the amount of fuel added. 3. After at least 3 fill-ups, fill the fuel tank and record the current odometer reading. 4. Subtract your initial odometer reading from the current reading. Use one of the following simple calculations to determine fuel economy: • Liters x 100 Ϭ total kilometers • Miles traveled Ϭ gallons used Keep a record for at least one month and record the type of driving (city or highway). You can also keep records in summer and winter to determine how temperature impacts fuel economy. Note that ethanol decrease fuel economy. 189
