3. Open the fuel filler door and remove any visible debris from the fuel

fill opening.

4. Insert either the fuel fill nozzle or the fuel fill funnel provided with the

vehicle several times to dislodge any debris and/or allow the inlet to

close properly.

If this action corrects the problem, the message may not reset immediately.

It may take several driving cycles for the message to turn off. A driving

cycle consists of an engine start-up (after four or more hours with the

engine off) followed by city/highway driving. Continuing to drive with the

message on may cause the service engine soon lamp to turn on as well.

FUEL CONSUMPTION

Filling the Tank

The advertised capacity is 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 amount of fuel in the tank after the fuel gauge indicates empty.

Note: The amount of usable fuel in the 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:

• 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.
