^ Rollover Protection bars are activate (tested) by performing J234-Airbag Control Module, output DTM, using Guided Fault Finding in the VAS 5051 Diagnostic tool.

To prevent damage to the rear glass and rollover protection covers, precautions MUST be taken prior to testing the rear roll-over protection bars.
