	Checking
	Risk of injury caused by moving parts that can pinch, crush or, in extreme cases even sever extremities.	Always remove ignition key when working on windshield wiper mechanism.	AS82.30-Z-0001-01A
		Make sure when working on lifted wiper arms that they do not fall onto the windshield. Otherwise the windshield will be damaged.
1	Switch off ignition and remove the transmitter key from the EIS [EZS] control unit	On vehicles with code (889) Keyless Go: Press keyless go start/stop button repeatedly until ignition is switched off. Remove transmitter key from vehicle and store it in a location beyond its transmission range (at least 2 m).
2	Check wiper blades, replace if necessary	Check for wear and damage.
3	Check position of wiper arms in parked position against markings (arrows C) in the windshield	The ends of the wiper blade should be positioned on the markings (arrows C) and should be offset downward and upward a maximum of 10 mm. The distance from the outer marking to the A-pillar (A) is approx. 60 mm, the distance from the inner marking to the A-pillar (B) is approx. 510 mm. Excessive deviations may be caused by a damaged wiper linkage, incorrect positioning of the wiper arms on the linkage pins, or bent wiper arms. Replace damaged components, see: ↓

On vehicles with code (889) Keyless Go: Press keyless go start/stop button repeatedly until ignition is switched off. Remove transmitter key from vehicle and store it in a location beyond its transmission range (at least 2 m).
5	Move wiper arms manually to upper reverse position.	Upper reversing position: The distance from the upper end of the driver-side wiper blade to the driver-side A-pillar (D) is approx. 30 mm, The distance from the upper end of the passenger-side wiper blade to the driver-side A-pillar (D) is approx. 460 mm,
	Measure
6	Check angle of incidence of wiper arms to windshield	Select a suitable adjustment method on the basis of the result of the check.	AR82.30-P-6000-01GZ
