The advertised capacity is the indicated capacity and the empty reserve combined. Indicated capacity is the difference in the amount of fuel in the fuel tank and when the fuel gauge indicates empty.
The amount of fuel in the empty reserve varies and should not be relied upon to increase driving range.
When refueling your vehicle after the fuel gauge indicates empty, you might not be able to refuel the full amount of the advertised capacity due to the empty reserve still present in the fuel tank.
Filling the Fuel Tank
For consistent results when refueling:
- Always switch the ignition off before refueling.If you leave the engine running, you will get an inaccurate reading.
- Use the same fill rate (low-medium-high) each time you fill the tank.
- Allow no more than two automatic shut-offs when refueling.
Results are most accurate when the filling method is consistent.
Calculating Fuel Economy
Do not measure fuel economy during the first
1000 mi (1,600 km) of driving (this is your engine’s break-in period). A more accurate measurement is obtained after
2000 mi (3,200 km) to
3000 mi (4,800 km). Also, fuel expense, frequency of fill ups or fuel gauge readings are not accurate ways to measure fuel economy.
- Fill the fuel tank completely and record the initial odometer reading.
- Each time you fill the fuel tank, record the amount of fuel added.
- After at least three fill ups, fill the fuel tank and record the current odometer reading.
- Subtract your initial odometer reading from the current odometer reading.
- To calculate L/100 km (liters per 100 kilometers) fuel consumption, multiply the liters used by 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.
- 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 economy may decrease with lower temperatures.
- Fuel economy may decrease when driving short distances.
- You will get better fuel economy when driving on flat terrain than when driving on hilly terrain.
