Highbeam On Light This light comes on when the high-beam headlamps are in use. Fuel Gage The fuel gage shows about how much fuel is left in the fuel tank when the ignition is on. See Headlamp High/Low-Beam Changer on page 3-9 for more information. When the indicator nears empty, there is still a little fuel left, but you should get more soon. Here are four things owners usually ask about the fuel gage. All these situations are normal and do not indicate a problem with the fuel gage: • At the gas station the pump shuts off before the gage reads full. • It takes more or less fuel to fill up than the gage indicates. For example, the gage reads half full, but it took more or less than half the tank's capacity to fill it. • The gage pointer may move while cornering, braking or speeding up. • The gage may not indicate full when the ignition is turned off. 3-54
