Maintenance and care 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 fuel tank completely and record the initial odometer reading (in kilometers or miles). 2. Each time you fill the tank, record the amount of fuel added (in liters or gallons). 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. Follow one of the simple calculations in order to determine fuel economy: Multiply liters used by 100, then divide by total kilometers traveled. Divide total miles traveled by total gallons used. 187
