5-10 Instruments and Controls Here are four things that some owners ask about. None of these indicate a problem with the vehicle's fuel gauge: . Fuel Gauge Engine Coolant Temperature Gauge At the gas station, the gas pump shuts off before the gauge reads full. It takes a little more or less fuel to fill up than the gauge indicated. For example, the gauge 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 gauge moves a little while turning a corner or speeding up. The gauge does not go back to empty when the ignition is turned off. This gauge shows the engine coolant temperature. If the gauge pointer is near the top of the gauge, the engine is too hot. It means that the engine coolant has overheated. . When the ignition is on, the fuel gauge shows how much fuel the vehicle has remaining in the fuel tank. An arrow on the fuel gauge indicates the side of the vehicle the fuel door is on. . . When the fuel in the fuel tank is low, a LOW FUEL message will display on the Driver Information Center (DIC). See Fuel System Messages on page 5‑27 for more information.
