taking fuel economy measurements during the first 1 600 km (1 000
miles) of driving (engine break-in period). You will get a more accurate
measurement after 3 000 km–5 000 km (2 000 miles-3 000 miles).

Filling the tank

The advertised fuel capacity of the fuel tank on your vehicle is equal to
the rated refill capacity of the fuel tank as listed in the Refill Capacities
chart in this “Owner Guide.” The advertised capacity is the amount of
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 small amount
of usable fuel remaining in the fuel tank after the fuel gauge indicates
empty.

The amount of Empty Reserve varies and should not be relied
upon to increase 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:
• Use the same filling rate setting (low — medium — high) each time

the tank is filled.

• Allow three automatic click-offs when filling.
• Always use the recommended octane rating of a known quality

gasoline, preferably a national brand.

• Use the same side of the same pump and have the vehicle facing the

same direction each time you fill up.

• Have the vehicle loading and distribution the same every time.
Your results will be most accurate if your filling method is consistent.

Calculating 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 (in liters
or gallons).

3. After at least three to five tank fill-ups, fill the fuel tank and record
the current kilometer (mileage) reading.

4. Follow one of the simple calculations in order to determine fuel
economy:
