General

NOTE: The safety instructions must be observed during work on the Cayenne S Hybrid. All work on hybrid vehicles may only be performed by qualified staff. Further information is provided in the Cayenne S Hybrid Training Information and in the "PIWIS Information System".

The Cayenne S Hybrid has many design features that utilize the high-voltage system in the vehicle. For example, the Cayenne S Hybrid has neither a 12 V generator nor an electric 12 V starter, as these components are replaced by the hybrid module, which is operated at 288 V.

The Cayenne S Hybrid can be driven purely on electric power thanks to its full parallel hybrid drive. After the combustion engine is switched off, various components, which are normally powered by the combustion engine, must be powered electrically.

Electric auxiliary systems

The Cayenne S Hybrid has the following electric auxiliary systems:
- Electrohydraulic servo pump
- Electric vacuum pump (brake booster)
- Spindle actuator (decoupler control)
- Electric air-conditioning compressor
