WARNINGTo avoid hot coolant or steam blowing out of the cooling system, use extreme care when removing the coolant expansion tank pressure cap. Wait until the engine has cooled down, then insulate the coolant pressure cap with a suitable cloth and slowly loosen the coolant expansion tank pressure cap until the cooling system pressure is released. Step back while the pressure is released from the system. When all of the pressure has been released slowly remove the coolant expansion tank pressure cap (still with the suitable cloth in position) from the coolant expansion tank. Failure to follow this instruction may result in personal injury.

WARNINGPlace the vehicle in a quarantined area and arrange "No Smoking/Petrol Fumes" signs about the vehicle.
WARNINGBefore any work is carried out on the fuel system, ground the vehicle to earth and maintain the ground connection until the work is complete.
WARNINGDo not smoke or carry lighted tobacco or open flame of any type when working on or near any fuel related components. Highly flammable vapors are always present and may ignite. Failure to follow these instructions may result in personal injury.
WARNINGThe fuel system remains pressurized for a long time after the ignition is switched off. The fuel pressure must be relieved before attempting any repairs. Failure to follow these instructions may result in personal injury.
WARNINGAfter carrying out repairs, the fuel system must be checked visually for leaks. Failure to follow these instructions may result in personal injury.
WARNINGThis procedure involves fuel handling. Be prepared for fuel spillage at all times and always observe fuel handling precautions. Failure to follow these instructions may result in personal injury.
WARNINGIf taken internally do not induce vomiting, seek immediate medical attention. Failure to follow these instructions may result in personal injury.
WARNINGIf fuel contacts the eyes, flush the eyes with cold water or eyewash solution and seek medical attention.
WARNINGWash hands thoroughly after handling, as prolonged contact may cause irritation. Should irritation develop, seek medical attention.
WARNINGDo not carry or operate cellular phones when working on or near any fuel related components. Highly flammable vapors are always present and may ignite. Failure to follow these instructions may result in personal injury.
