The fuel gage indicates about how much fuel is left when the ignition is turned on.

When the needle approaches the low fuel symbol, LOW FUEL will appear on the Driver Information Center (DIC) display. At this time, there is still have a little fuel left, but the vehicle's fuel tank should be filled soon.

Press RESET to acknowledge a DIC message(s). Pressing RESET will also turn off a DIC message but the LOW FUEL message will come on again in 10 minutes if fuel has not been added to the vehicle.

Here are five things that some owners ask about. All these things are normal and do not indicate that anything is wrong with the fuel gage.

    • At the gas station, the gas pump shuts off before the gage reads the full symbol.
    • It takes more (or less) fuel to fill up than the gage reads. For example, the gage reads half full, but it took more (or less) than half of the tank's capacity to fill it.
    • The gage pointer may move while cornering, braking or speeding up.
    • The gage may not indicate the tank is empty when the ignition is turned off.
    • The gage reading may change slightly within the first several minutes after starting the vehicle.

The Driver Information Center (DIC) can be used to show more detailed fuel information. The DIC, can also display:

    • AVERAGE XX.X MPG (Average Miles Per Gallon): The fuel economy calculated for the last 20 gallons (76 L) of fuel used, or since the display was last reset.
    • INST XX.X MPG (Instantaneous Miles Per Gallon): The fuel economy calculated for current driving conditions.
    • RANGE XXX MI: The approximate distance that can be driven before refueling.

See DIC Operation and Displays for more information.

The fuel information display should be reset every time the vehicle is refueled. To reset AVERAGE, use the information up or down button to scroll to AVE FUEL ECON and hold the reset button. RANGE will automatically reset.
