Fuel and Refueling

Calculating Fuel Economy Do not measure fuel economy during the first 1,000 mi (1,600 km) of driving (this is your engine’s break-in period). A more accurate measurement is obtained after 2,000 mi (3,200 km) to 3,000 mi (4,800 km). 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 fuel tank, record the amount of fuel added. 3. After at least three fill ups, fill the fuel tank and record the current odometer reading. 4. Subtract your initial odometer reading from the current odometer reading. To calculate L/100 km (liters per 100 kilometers) fuel consumption,multiply the liters usedby 100, then divide by kilometers traveled. To calculate MPG (miles per gallon) fuel consumption, divide miles traveled by gallons used. Keep a record for at least one month and record the type of driving (city or highway). This provides an accurate estimate of your vehicle's fuel economy under current driving conditions. Keeping records during summer and winter will show how temperature impacts fuel economy. Conditions • Heavily loading your vehicle reduces fuel economy. • Carrying unnecessary weight in your vehicle may reduce fuel economy. • Adding certain accessories to your vehicle such as bug deflectors, rollbars or light bars, running boards and ski racks may reduce fuel economy. • Using fuel blended with alcohol may lower fuel economy.

• Fuel economymaydecreasewith lower temperatures. • Fuel economy may decrease when driving short distances. • You will get better fuel economy when driving on flat terrain thanwhen driving on hilly terrain. EMISSIONCONTROL SYSTEM WARNINGS Do not park, idle, or drive your vehicle in dry grass or other dry ground cover. The emission system heats up the engine compartment andexhaust system, which can start a fire. 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 that 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.
