Problems that result from using methanol/gasoline blends are not the responsibility of The manufacturer and may not be covered by the vehicle warranty. While MTBE is an oxygenate made from Methanol, it does not have the negative effects of Methanol.

The MMT content of gasoline may not be indicated on the gasoline pump, therefore you should ask your gasoline retailer whether or not his/her gasoline contains MMT. It is even more important to look for gasolines without MMT in Canada because MMT can be used at higher levels than allowed in the United States.

This vehicle may be sold nationwide. Your vehicle will operate satisfactorily on fuels meeting Federal specifications, but emission control system performance may be adversely affected. Gasoline sold outside of California is permitted to have higher sulfur levels which may affect the performance of the vehicle's catalytic converter. This may cause the 5
