Fuel and Refueling If this action corrects the problem, the message may not reset immediately. It may take several driving cycles for the message to turn off. A driving cycle consists of an engine start-up (after four or more hours with the engine off) followed by city or highway driving. Continuing to drive with the message on may cause the service engine soon lamp to turn on as well. Empty reserve is the amount of fuel remaining in the tank after the fuel gauge indicates empty. Do not rely on this fuel for driving. The usable capacity of the fuel tank is the amount of fuel that can be put into the tank after the gauge indicates empty. The advertised capacity is the total fuel tank size - it is the combined usable capacity plus the empty reserve. Calculating Fuel Economy Do not measure fuel economy during the first 1000 miles (1600 kilometers) of driving (this is your engine's break-in period); a more accurate measurement is obtained after 2000 miles - 3000 miles (3200 kilometers 4800 kilometers). Also, fuel expense, frequency of fill ups or fuel gauge readings are not accurate ways to measure fuel economy. 1. Fill the fuel tank completely and record the initial odometer reading. 2. Each time you fill the tank, record the amount of fuel added. 3. After at least three to five tank fill ups, fill the fuel tank and record the current odometer reading. 4. Subtract your initial odometer reading from the current odometer reading. 5. Calculate fuel economy by dividing miles traveled by gallons used (For Metric: Multiply liters used by 100, then divide by kilometers traveled). FUEL CONSUMPTION Note: 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. Filling the Tank For consistent results when filling the fuel tank: • Turn the ignition off before fueling; an inaccurate reading results if the engine is left running. Use the same fill rate (low-medium-high) each time the tank is filled. Allow no more than two automatic click-offs when filling. • • Results are most accurate when the filling method is consistent. 167 MKZ (), enUSA
