	Remove/install
1	Disconnect charging cable connector of high-voltage on-board electrical system and wait 30 s until power-down is complete.	If high-voltage on-board electrical system is charged via a charging cable connector.
2	Disconnect charger from on-board electrical system battery.	When an external charger is connected.
3	Move driver seat to rearmost position.
4	Switch off ignition and store transmitter key outside of transmission range (min. 2 m).	Wait for a run-on time of approx. 2 minutes after the ignition is switched off and before disconnecting the ground line (1).
5	Remove trim (2).
6.1	Release electrical connector (3) (arrow A) and disconnect in direction of arrow (arrow B) with ground line (1).	Model 907 with code E30 (Battery master switch) Removal  : Position the ground line (1) so that there is no inadvertent contact with vehicle ground.
6.2	Remove nut (4) and remove ground line (1).	Model 907 except code E30 (Battery master switch) Removal  : Position the ground line (1) so that there is no inadvertent contact with vehicle ground. Nut, ground line to body	*BA54.10-N-1003-01TS
	Check
7	Check for absence of voltage on 12 V onboard electrical system. Service Information: Determine absence of voltage of 12 V on-board electrical system after removing the ground or positive line of the on-board electrical system battery	with code ME0 (Electric motor 85 kW)
	000 588 07 19 00 Measuring instrument	The engine hood must be closed. Observe the Service Information.
8	Expose positive line on on-board electrical system battery.	Model 907	AR54.10-D-0009TSR
9	Check on-board electrical system, using a diode test lamp, for voltage between positive line of on-board electrical system battery and disconnected ground line (1).	If the diode test lamp lights up, the onboard electrical system is still active because of a defect in the electrical system. If the diode test lamp lights up, ↓ Disconnect ground line of auxiliary battery for park pawl emergency shift mode or condenser for park pawl emergency shift mode, and check again after completing work on the onboard electrical system. Disconnect/connect ground line of capacitor for park pawl emergency shift mode Model 907 with code EE5 (ULTRACAP - Automatic transmission lock) with code G42 (7G-TRONIC PLUS) Model 907 with code EE5 (ULTRACAP - Automatic transmission lock) with code G43 (9G-TRONIC)	AR54.10-D-0056TS
		Disconnect/connect ground line of auxiliary battery for park pawl emergency shift mode Model 907 with code G42 (7G-TRONIC PLUS) except code EE5 (ULTRACAP - Automatic transmission lock) Model 907 with code G43 (9G-TRONIC) except code EE5 (ULTRACAP - Automatic transmission lock)	AR54.10-D-0026TSR
10.1	Expose fuse holder at driver's seat and remove electrical fuse 32 (F55/4f32) from fuse slot 32A of driver's seat fuse holder. Assignment of fuse holders on seat base	Model 907 with code G42 (7G-TRONIC PLUS) Model 907 with code G43 (9G-TRONIC) If the vehicle is to remain unused for more than 20 days. If the vehicle is to remain unused for longer than 20 days, remove electrical fuse 32 (F55-/4f32). Otherwise the Emergency-P battery will be discharged and destroyed through deep discharging. : When commissioning the vehicle, make sure that an intact electrical fuse (F55/4f32) (10 A) is inserted into the fuse slot 32A of the driver's seat fuse holder.	GF54.15-D-1257-11TSA
10.2	Expose fuse and relay module on front passenger side then remove electrical fuse 30-6 (F152f30-6) from fuse slot 6 of plug S16 on front passenger side fuse and relay module.	If the vehicle is to remain unused for more than 20 days. Remove/install vehicle tool kit carrier plate	AR68.30-D-5021TS
	Assignment of passenger-side footwell fuse and relay module	If the vehicle is to remain unused for longer than 20 days, remove electrical fuse 30-6 (F152f30-6). Otherwise the Emergency-P battery will be discharged and destroyed through deep discharging. : When commissioning the vehicle, make sure that an intact electrical fuse 30-6 (F152f30-6) (10 A) is inserted back into the fuse slot 6 of the plug S16 on the front passenger side fuse and relay module.
