WARNING: Natural gas is highly flammable. In order to reduce the risk of fire and personal injury, keep sparks, flames, and smoking materials away from the vehicle while you perform the Compressed Natural Gas (CNG) fuel system service. The Compressed Natural Gas (CNG) system operates at pressures up to 3600 psi (24,820 kPa). Relieve the CNG fuel system pressure before servicing CNG fuel system components in order to reduce the risk of fire and personal injury.

NOTE: Combustible Gas Detector (J-45878) is required for this procedure. See Figure .
