Maintenance and care Calculating fuel economy To accurately calculate your vehicle's fuel economy: 1. Fill the tank completely and record the initial odometer reading. 2. Each time you fill the tank, record the amount of fuel added (in liters or gallons). 3. After at least three to five fuel tank fill-ups, fill the fuel tank and record the current mileage reading. 4. Use one of the following equations to calculate fuel economy. Liters used x 100 Ϭ Total kilometers traveled Total miles traveled Ϭ Total gallons used Keep a record for at least one month. This will provide an accurate estimate of the vehicle's fuel economy. EMISSION CONTROL SYSTEM Your vehicle is equipped with various emission control components and a catalytic converter which will enable your vehicle to comply with applicable exhaust emission standards. To make sure that the catalytic converter and other emission control components continue to work properly: • Use only unleaded fuel. • Avoid running out of fuel. 187
