WARNING:

Never use an ohmmeter or similar tool to test airbags, door mounted inflatable curtains, adaptive seat belt tensioners, the adaptive steering column, rollover bar cassette or seat belt tensioners. Disconnect airbags, door mounted inflatable curtains, adaptive seat belt tensioners, adaptive steering column, rollover bar cassette or seat belt tensioners before testing them. Failure to do so may result in accidental deployment. This could result in serious injury or death.

The retractable roof has a lower level of protection than a vehicle with a fixed roof. ROPS (Roll Over Protection System) is available to sufficiently protect the passengers in the event of the vehicle rolling over. The system consists of two roll-over bars and sensors in the Supplemental restraint system module (SRS).

The roll-over bars are integrated in a cassette and the entire roll-over bar cassette must be replaced if replacing the roll-over bars. Both roll-over bar cassettes are installed between the body plates behind the rear seat backrest. The roll-over bar cassettes are directly connected to the Supplemental restraint system module (SRS).

The sensors for roll-over are installed in the Supplemental restraint system module (SRS) and the entire control module must be replaced if replacing a sensor.

The system is normally inactive and is only activated when the vehicle rolls.

In this case, the roll-over bar cassettes and the seat belt tensioners and the door mounted inflatable curtains activate as well.

WARNING:

Never use an ohmmeter or similar tool to test airbags, door mounted inflatable curtains, adaptive seat belt tensioners, the adaptive steering column, rollover bar cassette or seat belt tensioners. Disconnect airbags, door mounted inflatable curtains, adaptive seat belt tensioners, adaptive steering column, rollover bar cassette or seat belt tensioners before testing them. Failure to do so may result in accidental deployment. This could result in serious injury or death.
