Removing


Danger of unintended engine ignition.

Turn off the ignition and remove the ignition key from the vehicle interior for all work performed on the high voltage vehicle.


Damaged high voltage components may produce dangerously high voltage.

Observe the following when working near or around high voltage components and cables:

• Do not use tools that have sharp edges, that are used for cutting or shaping, or that generate heat, such as welding, soldering, hot air or thermal adhesive equipment.

• Inspect the high voltage components in the area where the work will be performed before starting the procedure.

• Perform a visual inspection of the electric drive power and control electronics (JX1) , electro-drive drive motor (V141) , the electrical A/C compressor (V470) and the high voltage cables when working in the engine compartment.

• Perform a visual inspection of the high voltage cables and the covers when working on the floor panel.

• Perform a visual inspection of the high voltage cables and the electro-box with the high voltage system maintenance connector (TW) when working in the rear of the vehicle.

• Perform a visual inspection of all of the potential equalization cables.

Note the following when performing the visual inspection:

• None of the components may display any exterior damage.

• The high voltage cable insulation and the potential equalization cables may not be damaged.

• The high voltage cables may not be deformed in any way.

• Each high voltage component muss be labeled with a red warning label.
