 Danger!

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



When working on raised driver-side wiper arm (1) or front passenger side wiper arm (2) it has to be observed that they do not fall onto the windshield to prevent it from being damaged.

1

Move wiper system from park position

 To do this, turn on ignition (circuit 15 or circuit 15R) and turn wiper switch to position "Two". After the wiper system has left the park position, turn off ignition and turn back wiper switch to position "Zero".

2

Manually position wiper system into reversing position

 Distance between driver-side wiper blade and A-pillar (A) approx. 35 mm, distance between front passenger side wiper blade and A-pillar (B) approx. 350 mm.

 For left-hand drive vehicles, measured from the upper wiper blade end of the driver-side wiper blade (1) and the front passenger side wiper blade (2) to the inside of the left A-pillar.
For right-hand drive vehicles, measured from the upper wiper blade end of the driver-side wiper blade (1) and the front passenger side wiper blade (2) to the inside of the right A-pillar.

3

Remove wiper blades

 See Operator's Manual

4

Clean wiper blade mounts on driver-side wiper arm (1) and front passenger side wiper arm (2)

5

Measure angle of incidence of driver-side wiper blade (1) and front passenger side wiper blade (2) to windshield and record

 When changing from reversing position to park position it has to be observed that the driver-side wiper arm (1) and the front passenger side wiper arm (2) do not have any direct contact to the windshield to prevent it from being scratched.

Adjust angle of incidence of driver-side wiper arm (1) or front passenger side wiper arm (2) in park position

In the event that the test values deviate from the tolerance range in reversing position or in park position and reversing position:

AR82.30-P-6100-01Q

 Distort driver-side wiper arm (1) or front passenger side wiper arm (2) by at least the value of the tolerance deviation in reversing position.
