Fuel Consumption
Nominal Capacity
The stated capacity is the maximum amount of fuel you can add to the fuel tank when the fuel gauge indicates empty. Refer to Capacities and Specifications.
In addition, the fuel tank contains a reserve. The reserve is the unmeasured amount of fuel that remains in the fuel tank when the fuel gauge indicates empty.
Filling the Fuel Tank
For consistent results when refueling:
- Turn the ignition off before refueling. An inaccurate reading occurs if the engine remains running.
- Use the same fill rate (low-medium-high) each time the tank is filled.
- Allow no more than one automatic shut-off when refueling.
Results are most accurate when the filling method is consistent.
Calculating Fuel Economy
Your vehicle calculates fuel economy based on the average value of the trip computer fuel function. Refer to Information Displays.
The first 1000 miles (1500 km) of driving is the engine break-in period. A more accurate measurement is obtained after 2000 miles (3000 km).
- Fill the fuel tank completely and record the initial odometer reading. Refer to Refueling.
- Each time you fill the fuel tank, record the amount of fuel added.
- After at least three refuelings, fill the fuel tank completely and record the current odometer reading.
- Subtract the initial odometer reading from the current odometer reading.
To calculate fuel consumption in L/100 km (liters per 100 kilometers), multiply the liters used by 100, then divide by the kilometers driven. To calculate MPG (miles per gallon), divide the miles driven by the gallons used.
Keep records for at least one month and note the type of driving, for example city or highway. This provides an accurate estimate of your vehicle's fuel economy under current driving conditions. Keeping records during summer and winter shows how temperature affects fuel consumption.
Conditions
- Heavy vehicle loads reduce fuel economy.
- Carrying excess weight in the vehicle may reduce fuel economy.
- Do not add accessories that increase aerodynamic drag, such as insect deflectors, roof racks for cargo, and ski or bicycle carriers.
- Using fuel blended with alcohol may reduce fuel economy.
- Fuel economy may decrease at lower temperatures.
- Fuel economy may decrease when driving short distances.
- You will get better fuel economy when driving on level terrain than when driving in hilly terrain.
