This function estimates how many miles or kilometers you can drive with the fuel remaining in your tank under standard driving conditions. Remember to turn off the ignition when filling up with fuel. Otherwise, the display will not show the addition of fuel for a few miles. When you have approximately 50 miles (80 km) left before you run out of fuel, the DTE function will flash for five (5) seconds and sound a tone for one (1) second. The message center will remain in the DTE function until you push the select button to change it. This low fuel warning also happens at 25 miles (40 km), and 10 miles (16 km). Displayed DTE will not be equal to AVG ECON multiplied by the FUEL REMAIN value. This is because DTE is calculated using a method that takes into consideration the fuel economy of the last 500 miles (800 Km) driven. NOTE: When refueling, at least 2.5 gallons (9.5 litres) of fuel must be added for fuel gauge to immediately show the next level of fuel. 24
