Safety precautions when working on anti-roll protection

CAUTION!
The anti-roll protection to be deployed may cause injuries if people remain in the area of deployment.

Therefore no persons may be in the vehicle and in deployment area of anti-roll protection (maintain a minimum distance of 1 m) during the expanded output Diagnostic Test Mode (DTM).

Make sure that your hand is not located on the activation lever when anti-roll protection is slid on, danger of injury!

Do not allow any objects to fall into outlet openings of the deployed anti-roll protection. If that should be the case, anti-roll protection must not be slid in under any circumstances.

If anti-roll protection does not engage properly, there is a danger of injury by an unexpected deployment of anti-roll protection.

DTC memory of Engine Control Module (ECM) must be checked and erased beforehand.

Perform function test "Reset deployment of anti-roll bar".
