 	Remove/install
 Danger!	Risk of explosion caused by escaping natural gas or overheated compressed-gas tanks when working on natural gas powered vehicles. Risk of frostbite Escaping natural gas or contact with components near the valves when draining compressed-gas tanks may cause frostbite to exposed body parts. Risk of poisoning or risk of suffocation caused by inhaling natural gas.	Remove any sources of ignition. Ensure that the work area is adequately ventilated. Wear heat protective gloves.	AS00.00-Z-0018-01A
1	Close gas shutoff valves at compressed-gas tanks		AR47.10-D-0005A
 Danger!	Risk of accident caused by vehicle starting off by itself when engine is running. Risk of injury caused by contusions and burns during starting procedure or when working near the engine as it is running	Secure vehicle to prevent it from moving by itself. Wear closed and snug-fitting work clothes. Do not touch hot or rotating parts.	AS00.00-Z-0005-01A
2	Start engine and allow it to run with the vehicle stationary until the engine stops on its own.	 Push extraction hose onto exhaust pipe. After engine has stopped, switch ignition off. Gas system is adequately emptied after engine stops.
 Danger!	Risk of explosion caused by escaping oxyhydrogen gas. Risk of injury caused by caustic burns to eyes, skin and mucous membranes from battery electrolyte (contains diluted sulfuric acid) or metal spatter due to short circuit. Risk of burn injuries caused by short circuit. Risk of poisoning caused by swallowing battery electrolyte (contains diluted sulfuric acid) or absorption of lead over the skin or orifices	No fire, sparks, open flames or smoking. Wear acid-resistant gloves and clothing and safety glasses with side guards. Do not place any conductive objects on the battery and avoid any short circuit from battery positive to ground. Only fill liquid battery electrolyte (diluted sulfuric acid) into suitable and appropriately marked containers.	AS54.10-Z-0001-01A
3	Disconnect ground lead from battery
4	Remove air intake hose (1)		AR09.10-D-8030C
5	Detach vacuum lines (2, 3) from the intake manifold		AR09.20-D-1310-06C
			*BA09.20-N-1004-02A
6	Release control cable (4)		AR30.10-D-3070-02C
7	Detach intake manifold (17) from cylinder head		AR09.20-D-1310-07D
			*BA09.20-N-1001-02A
8	Install in the reverse order
9	Adjust linkage		AR30.10-D-1010A
10	Program the control unit version	 Switch on ignition for this step, do not depress accelerator.
