Instrumentation and controls FUEL SELECTOR SWITCH This booklet supplements your Owner's Guide and is part of the owner's portfolio. It describes the operation of your Bi-fuel vehicle and how it differs from a standard gasoline powered vehicle. Therefore it is very important that you read this guide and thoroughly familiarize yourself and others operating the vehicle with this information. The fuel selector switch allows you to select which fuel your Bi-fuel vehicle will operate on. 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. Prior to starting the vehicle (with the ignition in the OFF position), determine which fuel you would like to use and press the rocker switch located on the dash panel. When the selector switch is placed in the ALT position, your engine will operate in the gaseous fuel mode, ALT running on CNG or LPG (depending upon application). GAS • A green indicator light will illuminate on the fuel selector switch to indicate that the vehicle is operating in the gaseous fuel mode (CNG or LPG , depending upon application). • The green indicator light operates independently of the fuel selector switch and is controlled by the compuvalve. When the selector switch is placed in the GAS position, your engine will operate in the unleaded gasoline ALT mode. GAS 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 green indicator light on the fuel selector switch will turn off to show the vehicle has changed to the unleaded gasoline operating mode. 13
