Wiper Arm: Adjustments

Windshield Wiper Arms, Adjusting

Procedure

• If the windshield wiper motor is to be run during the work procedure, the hood must be closed, otherwise the voltage supply of the wiper motor will be interrupted.

- Remove the windshield wiper arms. Refer to => [ Windshield Wiper Arms ] Removal and Replacement.

- Switch ignition on.

- Activate "one-tap wiping" and let the wiper motor run into its end position.

• Every second time the wiper motor is switched off, it returns the wiper arms to a slightly lower rest position, thus tipping the wiper blade lips the other way.

• To do so, the wiper motor moves the wiper arms farther down than to rest position and then a bit up again. This lower rest position must not be used to adjust the wiper crank.

• Only use end position where wiper arms run directly to end position with no understroke. Activate "one-touch wiping" again if necessary.

- Switch ignition off.

- Position wiper arm with wiper blade installed at wiper axle and align wiper blade at windshield as follows:






• Dimension - a - = 25 + 10 mm.

• Dimension - b - = 15 + 10 mm.

• The dimensions give the distance of the wiper blade tips to the cowl panel trim on the lower edge of the windshield.

- Tighten the nuts - 2 - on the windshield wiper arms - 1 -.






• Tightening specification, refer to=> [ Windshield Wiper System Overview ] Windshield Wiper System Overview.

- Switch ignition on.

- Activate "one-tap wiping" and let the windshield wiper arms run into their end position.

- Switch ignition off.

- Check the position of the wiper arms one more time and adjust if necessary.

- Press the caps - arrows - onto the wiper arms.
