Driving ENGINE OPERATION Before you drive your Bi-fuel vehicle, read and understand all information found in the Driving chapter of your Owner's Guide and this supplement. The green indicator light will be illuminated on the fuel selector switch when the vehicle is operating ALT in the gaseous fuel mode (CNG or LPG , depending upon application). GAS The fuel selector switch only operates when the vehicle is at a stop with the ignition in the OFF position. If the fuel selector switch is moved while the vehicle is running, the gaseous fuel injection system will NOT automatically change fuel modes and no damage to the vehicle will occur. If the CNG or LPG (depending upon application) runs low during the operation of the vehicle in the gaseous fuel mode: • the gaseous fuel injection system will automatically change to the unleaded gasoline operating mode. • the operator may temporarily notice a slight hesitation. • the green indicator light on the fuel selector switch will go off. The vehicle's fuel system will NOT automatically change to the gaseous fuel mode (CNG or LPG , depending upon application), if the level of the unleaded gasoline runs low. 17
