Service Vehicle Soon Light This light will come onif you have certain non-emission related vehicle problems. Fuel Gage Your fuel gage shows about how much fuel isin your tank. I These problems may not be obvious and may affect vehicle performance or durability. Consult a qualified Buick dealership for necessary repairs to maintain top vehicle performance. The light will come on briefly when your ignition is turned on to show that it is working properly. SERVICE VEHICLE SOON UNLEADED FUEL ONLY It works only when the ignition is on. When the indicator moves to the edge of the low fuel warning band, the low fuel lightwill turn on and a chime will sound. You still have a little fuel left, but you need to get more fuel right away. A concern owners have had about the fuel gage is that it takes more (or less) gas to fill up than the gage indicated. For example, the gage may have indicated half full, but it took more (or less) than half of the tank's capacity to fillit. This situation is normal and indicates nothing wrong with the fuel gage. 2-81
