Tow/Haul Mode Light This light comes on when the Tow/Haul mode has been activated. When the ignition is on, the fuel gage tells you about how much fuel you have left in the fuel tank. The gage will first indicate empty before you are out of fuel, and you should get more fuel as soon as possible. When the fuel tank is low on fuel, the FUEL LEVEL LOW message will appear on the Driver Information Center (DIC). For more information see DIC Warnings and Messages on page 3-56. Here are some situations you may experience with your fuel gage. None of these indicate a problem with the fuel gage. For more information, see Tow/Haul Mode on page 2-34. 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 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 gage goes back to empty when you turn off the ignition.
