FUEL CONSUMPTION

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.

• 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 292). 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 filling the fuel

tank:

• 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 two automatic

click-offs when filling.

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); a more accurate measurement is

obtained after 2000 miles - 3000 miles

(3200 kilometers - 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 3 to 5 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 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 1 month and

record the type of driving (city or highway).

This provides an accurate estimate of the

vehicle’s fuel economy under current

driving conditions. Additionally, keeping

records during summer and winter show

how temperature impacts fuel economy.

In general, lower temperatures mean lower

fuel economy.

Conditions

• Heavily loading a vehicle or towing a

trailer may reduce fuel economy at any

speed.

• Carrying unnecessary weight may

reduce fuel economy (approximately

1 mpg [0.4 km/L] is lost for every 400

pounds [180 kilograms] of weight

carried).
