Check

1

Check driver-side wiper blade (3) and passenger-side wiper blade (4) for wear and damage


When working on raised driver-side wiper arm (1) or passenger-side wiper arm (2), ensure that they do not fall onto the windshield.
Otherwise windshield will be damaged.

If wear or damage present



Replace wiper blades

2

Check position of driver-side wiper arm (1) and passenger-side wiper arm (2) in parked position using markings (C) (arrows) at windshield

 The wiper blade ends must lie on the markings (C) (arrows) and may not be offset upwards or downwards by more than 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 (1, 2) on the linkage pins, or bent wiper arms (1, 2).

If damage is present



Replace windshield wiper system

3

Position wiper arms (1, 2) in reversing position

 The reversing position of the driver-side wiper arm (1) corresponds to the distance between the upper end of the driver-side wiper blade and the driver-side A-pillar (D) of approx. 30 mm.
The reversing position of the passenger-side wiper arm (2) corresponds to the distance between the upper end of the passenger-side wiper blade and the driver-side A-pillar (E) of approx. 460 mm.
