	Remove/install
1	Perform disable for high-voltage on-board electrical system.		AR54.10-P-1150LW
2.1	Loosen left and right trunk lining until the screws (1) are accessible.	Model 205.047/147	AR68.30-P-4600LW
2.2	Detach load compartment trim at left and right side in rear area until the screws (1) are accessible.	Model 205.247	AR68.30-P-1180LWS
3	Confirm change of on-board electrical system battery (G1) using diagnosis system in signal acquisition and actuation module under Actuation menu item.	When replacing the on-board electrical system battery (G1).
		This updates the charging characteristic for the on-board electrical system battery (G1)	AD00.00-P-2000-04B
4	Disconnect the ground line for the on-board electrical system battery (G1).		AR54.10-P-0003LW
5	Release and disconnect electrical connector (2).
6	Remove nuts (3).
7	Remove coolant pump (4) with connected electric lines and coolant hoses and place to one side.
8	Remove screw (5).	Screw/bolt, crash bar to crash bar bracket	*BA64.20-P-1003-01H
9	Remove bolts (1).	Screw/bolt, crash bar to longitudinal member	*BA64.20-P-1002-01H
10	Remove crash bracket (6).
11	Unfasten nuts (7).	Nut, crash strut to protective rail	*BA64.20-P-1005-01H
