41 00... Procedure For Folding Hardtop After An Accident

The hardtop may be under tension after the vehicle has incurred damage following an accident. Moving the hardtop by hydraulic means may result in irreparable damage. For this reason, the hardtop may only be moved manually until the damaged has been repaired.

IMPORTANT: It is not possible to check the correct operation of the folding roof on the damaged vehicle.

Different procedures are required, depending on the degree of damage which the vehicle has incurred. The repair instructions for emergency operation  See 5437290 HARDTOP EMERGENCY OPENING or 5437295 EMERGENCY CLOSING HARDTOP describe only the complete sequences for manually opening and closing the hardtop.

When removing the roof module and/or the rear module, it is possible to move the hardtop manually into the necessary intermediate positions in each case.

WARNING: Risk of injury due to the heavy weight of the hardtop!
Since the hydraulic system may have to be depressurized during manual movement of the hardtop, there is an increased risk of injury by trapping. Secure the hardtop permanently and adequately against unintentional movement.

After body repairs to the vehicle 

All the hardtop components screwed/bolted to the body are precisely screwed/bolted to the vehicle at the factory by means of gauges. This affects above all the base plates and consoles of the roof and rear modules. To minimize extensive adjustment work after a body repair as much as possible, only remove those components which are screwed/bolted to a damaged body part.
