• Battery terminal clamps must be fitted only by hand without force to prevent damage to battery housing.Battery terminals must not be greased.
• See connecting plan in appropriate current flow diagram .

🔩 Torque settings

Values can differ between engine variants — check the code stamped on your block.

ℹ️ Always cross-check the exact figure against your vehicle's factory manual before final tightening — a wrong torque can damage the engine. These values are extracted from workshop data and may not cover every variant or revision.

📋 Procedure

1. Install battery so that the lug of the battery carrier (arrow) engages in the battery base strip recess (1).
2. On batteries with a hose for central venting ensure that the hose is not pinched. Only then can the battery vent freely.
3. Ensure that the opening on the upper side of the battery cover is not blocked on batteries without a hose for central venting.
4. Install retaining bracket and tighten M8×25 securing bolt (arrow) to 22 Nm. — 22 Nm (16 lb-ft)
5. If removed reinstall the heat insulation jacket.

6. Fit positive cable clamp onto battery positive terminal. [Note: Battery terminal clamps must be fitted only by hand without force to prevent damage to battery housing.Battery terminals must not be greased.]
7. Tighten battery positive terminal clamp securing bolt (arrow) to 6 Nm. — 6 Nm (4.4 lb-ft)
8. Fit fuse holder onto battery, when doing this fit current conductor plate onto securing pins on battery positive terminal.
9. Engage fuse holder spring catch in battery.
10. Tighten securing bolt to 6 Nm. — 6 Nm (4.4 lb-ft)
11. Close heat insulation jacket if necessary.
12. Tighten current conductor plate securing nut (1) on positive (+) terminal clamp.
13. Reconnect wiring/cables to strip fuses again if they have been disconnected and tighten securing bolts (2). [Note: See connecting plan in appropriate current flow diagram .]
14. Reconnect connector (3).
15. Fit fuse holder cover and close.
