Subtract your initial odometer reading from the current odometer reading. 5. Calculate fuel economy as follows: Standard: Divide miles traveled by gallons used. Metric: Multiply liters used by 100, then divide by kilometers traveled. Keep a record for at least one month and record the type of driving (city or highway). This provides an accurate estimate of the vehicle's fuel economy under current driving conditions. Additionally, keeping records during summer and winter show how temperature impacts fuel economy. In general, lower temperatures mean lower fuel economy. EMISSION CONTROL SYSTEM WARNING: Do not park, idle, or drive your vehicle in dry grass or other dry ground cover. The emission system heats up the engine compartment and exhaust system, which can start a fire. WARNING: Exhaust leaks may result in entry of harmful and potentially lethal fumes into the passenger compartment. If you smell exhaust fumes inside your vehicle, have your dealer inspect your vehicle immediately. Do not drive if you smell exhaust fumes. 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 the specified fuel listed. • Avoid running out of fuel. • Do not turn off the ignition while your vehicle is moving, especially at high speeds. • Have the items listed in Scheduled Maintenance Information performed according to the specified schedule. The scheduled maintenance items listed in Scheduled Maintenance Information are essential to the life and performance of your vehicle and to its emissions system. 2013 Focus (foc) Owners Guide gf, 3rd Printing, November 2012 USA (fus)
