5.To install the cap, align the tabs on thecap with the notches on the filler pipe.
6.Turn the filler cap clockwise 1/4 of aturn clockwise until it clicks at leastonce.
If the Check Fuel Cap light or a Check FuelCap message appears in the instrumentcluster and stays on after you start theengine, you may not have installed the fuelfiller properly.
If the fuel cap light remains on, at the nextopportunity, safely pull off of the road,remove the fuel filler cap, align the capproperly and reinstall it. The check fuel caplight or Check fuel cap message may notreset immediately. It may take severaldriving cycles for the indicators to turn off.A driving cycle consists of an enginestart-up (after four or more hours with theengine off) followed by normal city andhighway driving.
FUEL CONSUMPTION
Empty reserve is the amount of fuelremaining in the tank after the fuel gaugeindicates empty. The amount of usablefuel in the empty reserve varies and shouldnot be relied upon to increase driving range.
•The usable capacity of the fuel tank isthe amount of fuel that can be addedinto the tank after the gauge indicatesempty
•The advertised capacity is the total fueltank size. See Capacities andSpecifications (page 110). It is thecombined usable capacity plus theempty reserve.
•Due to the empty reserve, you may notbe able to refuel the full amount of theadvertised capacity of the fuel tankeven when the fuel gauge reads empty.
Filling the Tank
For consistent results when filling the fueltank:
•Turn the ignition off before fueling; aninaccurate reading results if the engineis left running.
•Use the same fill rate(low-medium-high) each time the tankis filled.
•Allow no more than two automaticclick-offs when filling.
Results are most accurate when the fillingmethod is consistent.
Calculating Fuel Economy
Do not measure fuel economy during thefirst 1000 miles (1600 kilometers) ofdriving (this is your engine’s break-inperiod); a more accurate measurement isobtained after 2000 miles - 3000 miles(3200 kilometers - 4800 kilometers). Also,fuel expense, frequency of fill ups or fuelgauge readings are not accurate ways tomeasure fuel economy.
1.Fill the fuel tank completely and recordthe initial odometer reading.
2.Each time you fill the tank, record theamount of fuel added.
3.After at least 3 to 5 tank fill ups, fill thefuel tank and record the currentodometer reading.
4.Subtract your initial odometer readingfrom the current odometer reading.
5.Calculate fuel economy by dividingmiles traveled by gallons used (ForMetric: Multiply liters used by 100, thendivide by kilometers traveled).
