FUEL CONSUMPTION
Filling the Tank
The advertised capacity is the indicated capacity and the empty reserve
combined. Indicated capacity is the difference in the amount of fuel in a
full tank and a tank when the fuel gauge indicates empty. Empty reserve
is the amount of fuel in the tank after the fuel gauge indicates empty.
Note:The amount of usable fuel in the empty reserve varies. Do not rely
on it to increase your 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 of the fuel tank due to the empty
reserve still present in the tank.
For consistent results when filling the fuel tank:
•Turn the ignition off before fueling. An inaccurate reading results if
you leave the engine running.
•Use the same fill rate (low–medium–high) each time you fill the tank.
•Allow no more than two automatic click–offs when filling.
•Have the vehicle loading and distribution the same every time.
•If your vehicle is equipped with dual fuel tanks, fill the tanks evenly
or the fuel gauge reading may fluctuate slightly until the fuel level
between the two tanks balances out and becomes equal.
Note:If your vehicle is equipped with dual fuel tanks add fuel to both
fuel tanks when refueling or engine performance may degrade.
Results are most accurate when the filling method is consistent.
Calculating Fuel Economy
Do not measure fuel economy during the first 1000 miles
(1600 kilometers) of driving; this is your engine’s break-in period. Start
measuring after driving 2000–3000 miles (3200–4800 kilometers). 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 tank, record the amount of fuel added.
3. After at least three to five tank fill-ups, fill the fuel tank and record
the current odometer reading.
4. 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.
