	Risk of explosion  when using a forming gas with incorrect mixing ratio. Risk of suffocation due to inhalation of forming gas. Risk of injury  due to bursting of high-pressure hoses.	Wear safety glasses and protective gloves. No smoking or open flames. Work in well-ventilated rooms only.	AS83.00-Z-0001-02A
	Risk of injury  caused by fingers being jammed or pinched when removing, installing or aligning hoods, doors, trunk lid/rear-end door or sliding roof.	No parts of the body or limbs should be within the operating area when the components are moving.	AS00.00-Z-0011-01A
