•
The usable capacity of the fuel tank is
the amount of fuel that can be added
into the tank after the gauge indicates
empty.
•
The advertised capacity is the total fuel
tank size. See Capacities and
Specifications (page 255). It is the
combined usable capacity plus the
empty reserve.
•
Due to the empty reserve, you may not
be able to refuel the full amount of the
advertised capacity of the fuel tank
even when the fuel gauge reads empty.
Empty reserve is the amount of fuel
remaining in the tank after the fuel gauge
indicates empty. The amount of usable
fuel in the empty reserve varies and should
not be relied upon to increase driving range.
Filling the Tank
For consistent results when filling the fuel
tank:
•
Turn the ignition off before refueling
your vehicle; a temporary inaccurate
reading may result if the engine is left
on when refueling your vehicle.
•
Use the same fill rate
(low-medium-high) each time the tank
is refueled.
•
Allow no more than two automatic
click-offs when refueling your vehicle.
Results are most accurate when the filling
method is consistent.
Calculating Fuel Economy
Do not measure fuel economy during the
first 900 mi (1,500 km) of driving (this is
your engine’s break-in period); a more
accurate measurement is obtained after
1,900 mi (3,000 km).
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.
5. Calculate fuel economy by dividing
miles traveled by gallons used (For
Metric: Multiply liters used by 100, then
divide by kilometers traveled).
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. In
general, your vehicle will use more fuel in
cold temperatures.
Conditions That Affect Fuel Economy
•
Heavily loading your vehicle or towing
a trailer may reduce fuel economy at
any speed.
•
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.
•
You will get better fuel economy when
driving on flat terrain than when driving
on hilly terrain.
