 Danger

Risk of fire/risk of explosion due to short circuit and escaping oxyhydrogen gas. Risk of (burn) injury caused by caustic burns to eyes, skin and mucous membranes from battery electrolyte/mist, short circuit and arcing. Risk of poisoning caused by swallowing battery electrolyte or absorption of lead through the skin or body orifices. Risk of death due to voltage U >= 30 V AC and U >= 60 V DC.

No fires, sparks, open flames, or smoking. Wear acid-resistant gloves, clothing, and glasses. Pour battery acid only into suitable and appropriately marked containers.

AS54.10-Z-0001-01A

 Warning

Risk of injury. Moving parts can pinch, crush or, in extreme cases even sever extremities.

No parts of the body or limbs should be within the operating area of mechanical components when moving components.


Switch off all electrical consumers.
Risk of damage to consumers when disconnecting/connecting ground line.

2

Switch off ignition and store transmitter key outside of transmitter range (min. 2 m).

Open hood.

Model 222.004/057/104/157/163/173

 Opening the hood deactivates the pre-entry climate control via the contact switch. This ensures that no currents are flowing in the 12 V on-board electrical system.
