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 370). 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.
Filling the 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
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.
WARNINGS
Do not park, idle, or drive your vehicle
in dry grass or other dry ground cover.
