Fuel Consumption

Nominal Capacity

The rated capacity is the maximum amount of fuel that can be added to the fuel tank after the fuel tank is emptied. The rated capacity includes the empty reserve. The empty reserve is the unspecified amount of fuel remaining in the fuel tank when the fuel gauge indicates empty.

Calculating Fuel Economy

Your vehicle calculates fuel economy figures through the trip computer average fuel function.

The first 1,000 miles (1,600 km) of driving is the engine break-in period. More accurate measurement is achieved after 2,000–3,000 miles (3,200–4,800 km).

Keep records for at least one month and note the type of driving, for example city or highway. This ensures an accurate calculation of your vehicle's fuel economy under current driving conditions. Keep records during both summer and winter, as temperature affects fuel economy.

Conditions Affecting Fuel Economy

  • Carrying unnecessary weight in your vehicle may reduce fuel economy.
  • Avoid adding accessories that increase aerodynamic drag on your vehicle, such as bug deflectors, car top carriers and ski or bicycle racks.
  • Remove empty roof racks and keep windows closed at high speed to reduce wind resistance and fuel consumption.
  • Check and adjust tire pressure regularly. Underinflated tires increase fuel consumption.
  • Rapid acceleration and braking reduce fuel economy. Drive smoothly, look as far ahead as possible and, where possible, avoid short trips.
  • Fuel economy decreases as temperature decreases.
  • Comfort features use additional energy and consume more fuel. Use the A/C and other comfort features only when necessary.
  • Using fuel blended with alcohol may increase fuel consumption.
