The malfunction indicatorlamp on your instrument panel may turn on and/or yourvehicle may fail a smog-check test. (See “MalfunctionIndicator Lamp” in the Index.) If this occurs, return toyour authorized Catera dealer for diagnosis to determinethe cause of failure. In the event it is determined that thecause of the condition is the type of fuels used, repairsmay not be covered by your warranty.Some gasolines that are not reformulated for lowemissions may contain an octane-enhancing additivecalled methylcyclopentadienyl manganese tricarbonyl(MMT); ask your service station operator whether ornot the fuel contains MMT.
