Introduction Introduction ABOUT THIS SUPPLEMENT This booklet supplements your Owner Guide and is part of the owner’s portfolio. It describes the operation of your natural gas vehicle (NGV) 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. Some of the information in this supplement replaces certain instructions in the Owner Guide. Please re

Introduction COMPRESSED NATURAL GAS (CNG) FUEL SYSTEM Your vehicle is equipped with a dedicated compressed natural gas (CNG) fuel system that is under high pressure. Depending upon the application, the CNG fuel system is rated at a pressure of 20,700 kPa (3,000 psi) at 21°C (70°F) or 24,800 kPa (3,600 psi) at 21°C (70°F). Refer to the label on the fuel filler door to determine the fuel system pressure rating. Use caution when servicing or maintaining any of the components of the CNG fuel system.

Instrumentation Instrumentation FUEL GAUGE The fuel gauge in your NGV behaves similarly to a typical gasoline fuel gauge. However, the gauge operation is based on the pressure and temperature of the natural gas, not on the level of liquid gasoline. Depending upon application, a fuel gauge reading of Full will occur at a pressure of approximately 20,700 kPa (3,000 psi) or 24,800 kPa (3,600 psi), at a temperature of approximately 21°C (70°F). The NGV fuel gauge will provide a linear reading from t

Servicing your vehicle ADAPTERS DO NOT use fuel receptacle adapters when refueling your vehicle. The profiles of both the natural gas vehicle receptacle and the fuel station nozzles are specified by ANSI/AGA NGV1-1994, CGA NGV1-M94. These profiles are specified for compressed natural gas vehicles and fuel stations for safety purposes. Three separate adapter profiles are available. P24, P30 and P36 respectively, are specified for the three different service pressures of 16,500 kPa (2,400 psi), 20

Servicing your vehicle indication that refueling is nearly complete. Also, the station compression equipment may turn on at any time during the refueling process. FUEL QUALITY Do not use liquefied natural gas (LNG) or a CNG that is derived from a process such as flashing (heating LNG). Failure to use the correct type of fuel may cause damage to the engine and fuel system components. Use only a CNG fuel that meets the specification of NFPA-52 and SAE J1616 in your NGV. Specifications NFPA-52 and

Servicing your vehicle SERVICING YOUR NATURAL GAS VEHICLE Service to the CNG fuel system should be conducted at a qualified dealership by a trained NGV technician only. Failure to do so may cause damage to components or cause bodily harm. FUELING Do not fuel your vehicle with the ignition on the ON position. Failure to do so may cause component damage. Fueling a NGV, with a few exceptions, is very similar to fueling a gasoline vehicle. The same care and cautions used when fueling a gasoline vehi

Servicing your vehicle Use caution when fueling your vehicle. Make sure the engine is turned off and all flammable material is extinguished. Observe all Dispensing Equipment Safety Standards and Operating Procedures. The procedure is the same for both fast-fill and slow-fill fueling. 1. Open fuel door and determine the pressure rating of your vehicle’s fuel system. 2. Remove protective cap from the vehicle’s fuel receptacle. Remove any debris that may be present. 3. Follow the natural gas fuelin
