DANGER:

- Danger of personal injury by placing objects within the functioning range of the roll-over bars.

The roll-over bars may be triggered accidentally or intentionally during the diagnosis/troubleshooting even if the battery was clamped beforehand.

- Ensure that body parts are kept away from the functioning range of the roll-over bars.
- Ensure that objects are kept away from the functioning range of the roll-over bars.
- During all work and analysis/troubleshooting on the roll-over protection system, roll-over protection must be actuated beforehand and only retracted again when all work is complete.

NOTE:
- Erase the fault memory before troubleshooting and perform a test drive.
- If the fault is entered in the fault memory again, carry out troubleshooting as described.
