	Remove/install
	Risk of death  when touching components on vehicles with high-voltage on-board electrical system	Do not touch components and open lines of the high-voltage on-board electrical system. Persons who wear electronic implants (e.g. cardiac pacemakers), must not carry out any work on high-voltage on-board electrical systems.	AS54.00-Z-0001-01A
1	Remove intake air duct upstream of air filter	MODEL 212.098/298
2	Unhook coolant circulation pump for transmission oil cooling (M13/7) at the bracket of oil cooler (2)	MODEL 212.098/298
3.1	Remove engine compartment paneling	MODEL 212.095/195
			AR61.20-P-1105EW
3.2	Remove bottom sections of soundproofing	MODEL 212.098/298
			AR94.30-P-5300EW
4	Disconnect transmission oil feed line (1a) or transmission oil return line (1b) at oil cooler (3) and at transmission (4)		AR27.10-P-0501-03CW
		Before disconnecting, the area around the transmission oil feed line (1a) or transmission oil return line (1b) must be cleaned thoroughly in the area of the separating points at the oil cooler (3) and transmission (4). Otherwise, dirt particles in the hydraulic components could lead to malfunction or total failure of transmission (4). Do not kink or bend the transmission oil feed line (1a) or the transmission oil return line (1b). Otherwise, the hydraulic system could fail or the transmission (4) could get damaged. The transmission oil feed line (1a) and transmission oil return line (1b) can be removed individually. Collect escaping oil and seal the line connections.
