WARNING: Risk of accidents! The Offroad Stabilizer System (ORS) operates at an overpressure of up to 165 bar. Under certain conditions, motions can occur on the wheel carrier (e. g., if the Offroad stabilizers are disengaged when lifting, the button is pressed on the center console, and the wheel carrier is also raised). The stabilizer can close quickly. 
  • Danger of crushing in the area of the stabilizers and wheel carriers. Injury and material damage due to raising the wheel carrier incorrectly. 

→ Before working on the vehicle, ensure that the ORS is engaged. The indicator light on the center console button must be OFF. If the indicator light is on, follow the following procedure: Switch on the ignition and engage the road driving programme >> High Range <<. The stabilizers must audibly engage.

→ Before working on the ORS, depressurize the system!. To do this, connect the Porsche System Tester and in the menu select >> Offroad Stabi (ORS) >> Drive links >> Clock valve VA or valve HA <<. The valve clocks (audibly) until the procedure is finished.

→ Do not raise the wheel suspension higher than the normal vehicle position (vehicle resting on wheels). When raising the suspension, use a suitable intermediate layer (hard rubber).

→ Do not damage the brake cover plate.

1. Release connecting link at stabilizer on left and right. To do this, use a suitable lift to raise the wheel carrier sufficiently for the pin of the connecting link to be pulled easily out of the stabilizer. Use a suitable lift with rubber base in order to prevent slipping. See Fig 3.
