Instruments and Controls This light should come on briefly as the engine is started. If it does not come on, have the vehicle serviced by your dealer. If the light comes on and stays on, it means that oil is not flowing through the engine properly. The vehicle could be low on oil and might have some other system problem. See your dealer. It also comes on when the fuel tank is low on fuel. The light turns off when fuel is added. If it does not, have the vehicle serviced. 5-27 High-Beam On Light Security Light This light comes on when the high-beam headlamps are in use. See Headlamp High/Low-Beam Changer on page 6-3.
