Instruments and Controls The fuel gauge, when the ignition is on, shows how much fuel the vehicle has left in the tank. An arrow on the fuel gauge indicates the side of the vehicle the fuel door is on. The gauge first indicates empty before the vehicle is out of fuel, and the vehicle's fuel tank should be filled soon. When the fuel tank is low, the FUEL LEVEL LOW message appears in the Driver Information Center (DIC). See Fuel System Messages on page 5‑39 for more information.

The gauge goes back to empty when the ignition is turned off. Engine Oil Pressure Gauge If the vehicle is a hybrid, see the hybrid supplement for more information.
