Self Study Program 450 – The Touareg Hybrid

VAG SSP 450. For the first time at Volkswagen, an electric hybrid drive, i.e. a combination of a combustion engine and an electric motor, will be available for use in of production in the Touareg 2011.

The Touareg Hybrid is a conventional vehicle concept which has been “hybridised”. The hybrid system can be classified as existing, tried-and-tested technology. During vehicle development, focus was placed on employee safety when handling the high-voltage systems.

Numerous shut-off functions and back-up facilities in the hybrid system prevent undesired dangers for workshop employees.

The combination of new high-voltage components and tried-and-tested technology from Volkswagen means that the Touareg Hybrid is leading the way into an increasingly electrified future.

Urgent warning
Please note that work which is carried out in the vicinity of, or on, the high-voltage components in the hybrid vehicle must only be undertaken by qualified and therefore authorised Volkswagen high-voltage technicians.
Improper handling of the high-voltage systems may lead to life-threatening situations due to an electric shock.
