	Remove/install
	Risk of death  caused by vehicle slipping or toppling off of the lifting platform.	Align vehicle between columns of vehicle lift and position four support plates at vehicle lift support points specified by vehicle manufacturer.	AS00.00-Z-0010-01A
	Risk of poisoning  caused by swallowing brake fluid. Risk of injury  caused by brake fluid coming into contact with skin and eyes.	Only pour brake fluid into suitable and appropriately marked containers. Wear protective clothing and eye protection when handling brake fluid.	AS42.50-Z-0001-01A
	Notes on self-locking nuts and bolts		AH00.00-N-0001-01A
		Installation: Attention, important information:  It is imperative that thread in the frame floor assembly is re-cut and blown out. Remaining glue residues in the thread prevent the necessary preload force of the bolt from being reached, despite the specified torque and angle being reached. If this is not observed, the faulty preload will generate bending forces on the bolt. This can lead to bolt failure.
		While working on the rear axle care must be taken to ensure that the surfaces of aluminum components do not get any scratches, cracks or notches. Otherwise the service life of the of the parts will be reduced.
		Installation:  Tighten nuts and bolts of chassis components only when vehicle is in the ready-to-drive condition.
