Deactivation of the high-voltage system

Pictogram for danger

Hydrogen components are marked with an appropriate warning label, as are the two hydrogen lines between the fuel cell and the anode module.

Pictogram for danger

The high-voltage system is automatically switched off in the event of accidents in which the airbags and seat belt pretensioners trigger.

In all other cases, the high-voltage system should be deactivated as follows:

High-voltage disconnect

The high-voltage disconnect device is located on the top of the refrigerant compressor (3) in the engine compartment on the left side.

Pull up retaining ring (1) / Unplug connector (2)

Pictogram for danger

In order to ensure that there is no longer any residual voltage in the high-voltage system, wait approx. 20 seconds after switching it off.

Pictogram for danger

The passive safety systems such as airbags and seat belt pretensioners will continue to be supplied with power by the 12-volt electrical system.

Disconnecting the 12 V battery

1. Remove the cover from the 12-volt battery in the engine compartment.
2. Disconnect the negative cable of the 12-volt battery at the screw connection and secure it against unintentional contact.
