Removing rain sensor
INFORMATION:
- An adhesive pad must be used when reinstalling the rain sensor.
- When fitting the adhesive pad, make sure there is no air trapped between the windscreen and the adhesive pad or between the adhesive pad and the rain sensor.
- When installing the adhesive pad, the temperature of the windscreen, rain sensor and adhesive pad must be approx 20 °C. Carefully heat the windscreen with a hot-air gun for example.
- Do not touch the adhesive surface of the sensor with your fingers.
- If the sensor is new, remove the protection cap before sticking the sensor on to the windscreen.
- When sticking on a new sensor, make sure that no air pockets are caught between the gel and the windscreen. Air pockets could impair the function of the sensor.
- Sensor, orientation lights, wires and wiring ducts are spare parts.
