- The windshield is replaced and the rain sensor is reused.
- The auto wiper system operates incorrectly.

1. Remove water and dirt from the windshield surface.

2. Switch the ignition to off.

3. Turn the windshield wiper switch to the AUTO position.

4. Within 10 s after switching the ignition to ON position, turn the windshield wiper switch from the AUTO to the OFF position for five times and return it to the AUTO position.When the initial setting is performed correctly, the windshield wiper operates once at low speed.

CAUTION:
- If the operation is too fast, the windshield wiper switch position cannot be detected and the initial setting may not be performed. Operate the windshield wiper switch for one cycle (AUTO->OFF->AUTO) per 1 s.
