The angle of incidence of the wiper arms

is always adjusted in parked position,
if the check values deviate from the tolerance range only in reversing position,
if the check values deviate from the tolerance range both in reversing position and parked position.

The adjuster levers (7) are attached with the side into which the marking "Z4" is imprinted to the driver-side wiper arm (1) or the passenger-side wiper arm. The wiper arm is twisted with the aid of one adjuster lever (7), which was positioned close to the angle gauge (5). The second adjuster lever (7) is used as a counterholder.

If the wiper arms are not in parked position:
Switch on ignition, switch off windshield wipers. When the wiper arms are in parked position, switch off ignition again, remove ignition key.

On vehicles with Keyless Go, code 889: 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).
Insert adapter "E" into the guide of the angle gauge (5) and fasten with knurled bolt (6a) to angle gauge (5).
Fold up driver-side wiper arm (1), remove driver-side wiper blade (3).
Slide adapter "E" together with the angle gauge (5) onto the wiper blade mount of the driver-side wiper arm (1) and clamp tight with the knurled bolt (6b).
Carefully lower driver-side wiper arm (1) onto windshield. All three contact points at the foot of angle gauge (5) must touch the windshield.
Attach adjuster levers (7) onto driver-side wiper arm (1).
Attach the adjuster levers (7) as far from each other as possible onto the driver-side wiper arm (1).
Press adjuster lever (7) into the required direction (arrow F) until the specified value is reached.
Remove adjuster levers (7) from wiper arm, check angle of incidence again.
The angle of incidence can change slightly when removing the adjuster levers (7), since the wiper arm is slightly twisted due to the dead weight of the adjuster levers (7).
Lift driver-side wiper arm (1), loosen knurled screw (6b), remove adapter "E" together with the angle gauge (5) from driver-side wiper arm (1).
Attach driver-side wiper blade (3), carefully fold driver-side wiper arm (1) onto windshield.
Repeat adjustment procedure 3 to 6 on passenger-side wiper arm.
