Removing and Installing

Rear Parking Aid Sensor

Removing

• All four rear parking aid sensors are removed the same way, so the procedure is only described for one sensor.

- Switch off the ignition and all electrical consumers and move the ignition key or start button into the 0 position (preliminary engaged position).

- Remove the rear bumper cover.

• Always follow the sequence for removing the sensor.

• Otherwise, the sensor may be damaged. Hairline cracks which lead to sensor failure can develop if too much force is used on the sensor.

• First remove the sensor from the bracket and then disconnect the sensor connectors.

- Press the tabs - arrows - on the sensor holder - 1 - outward and pull the sensor - 2 - out with the wires still connected.






• When removing the sensor, make sure that the coupling ring (black silicone ring) remains on the sensor head and not in the holder or that it gets lost.

• Do not bend the coupling ring.

- Unlock and disconnect the connector - 2 - and then remove the sensor - 1 -.






Installing

Install in reverse order of removal. Note the following:

• Do not bend the coupling ring.

• Using a damaged coupling ring can cause malfunctions.

• Replace damaged coupling rings.

• When installing the sensor, make sure the coupling ring (black silicone ring) is mounted on the sensor head correctly and that it does not fall off or become jammed when inserting into the sensor bracket.

• Both retaining tabs on the sensor must engage audibly in the sensor bracket when installing.

- Make sure the sensor is seated correctly in the bracket after installing. Dimension - a - for the circular gap between the sensor head and sensor bracket must be even all around on the outer side of the bumper cover.
