•
The usable capacity of the fuel tank is
the amount of fuel that you can add to
the fuel tank when the fuel gauge
indicates empty, before the first fuel filler
nozzle automatic shutoff event.
• The advertised capacity is equal to the
volumetric difference between actual fuel
fill before the first fuel filler nozzle
automatic shutoff event and the fuel
quantity when the fuel gauge indicates
empty. See Capacities and
Specifications (page 328). It is the usable
capacity minus the empty reserve.
• Due to the empty reserve, you may be
able to add more fuel than the advertised
capacity of the fuel tank when the fuel
gauge indicates empty. Filling the Fuel Tank
For consistent results when refueling:
•
Turn the ignition off before fueling; an
inaccurate reading results if the engine
is left 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
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 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.
