Operation process

Note If the wiper motor needs to be run during repair work, the bonnet must be closed (voltage supply to wiper motor is cut off when bonnet is open).

• Remove wiper arms.
• Switch on ignition.
• Actuate "touch wipe" function and allow wiper motor to move to end position.

Note

• Every second time the wiper motor is switched off it runs back slightly after reaching the end position, which turns the lip of the wiper blade in the opposite direction.
• The wiper motor moves the wiper arms down beyond their end position and then back up slightly. This slightly raised position must not be used when aligning the wiper crank.
• You must use the end setting at which the wiper motor moves directly to its park position (without returning). Operate the "touch-wipe" function again as necessary.

Removing
