WARNING:
Natural gas is highly flammable. To reduce risk of fire and personal injury, keep sparks, flames, and smoking materials away from vehicle while you perform Compressed Natural Gas (CNG) fuel system service. DO NOT allow fuel to contact engine or electrical components. CNG system operates at pressures up to 3600 psi (24,820 kPa). Release CNG fuel system pressure before servicing CNG fuel system components to reduce risk of fire and personal injury. Before servicing any electrical component, ignition must be in OFF or LOCK position and all electrical loads must be off, unless instructed otherwise in these procedures. If a tool or equipment could come in contact with a live exposed electrical terminal, also disconnect negative battery cable. Failure to follow these precautions may cause personal injury and/or damage to the vehicle or its components.
