Fuel Gage When the fuel tank is low, the FUEL LEVEL LOW message appears in the Driver Information Center (DIC). See DIC Warnings and Messages on page 3-64 for more information. Here are some situations owners may experience with the fuel gage. None of these indicate a problem with the fuel gage. • At the gas station, the fuel pump shuts off before the gage reads full. • It takes a little more or less fuel to fill up than the United States Canada fuel gage indicated. For example, the gage may have indicated the tank was half full, but it actually took a little more or less than half the tank's capacity to fill the tank. The fuel gage, when the ignition is on, shows how much fuel the vehicle has left in the tank. An arrow on the fuel gage indicates the side of the vehicle the fuel door is on. The gage first indicates empty before the vehicle is out of fuel, and the vehicle's fuel tank should be filled soon. • The gage goes back to empty when the ignition is turned off. For vehicles with a Two-mode Hybrid, see the Two-mode Hybrid manual for more information. 3-50
