Front Parking Aid and Parallel Parking Assistance Sensors

The following 6 sensors are located in front bumper cover:

• Left Front Parallel Parking Assistance Sensor (G568)

• Left Front Parking Aid Sensor (G255)

• Left Front Center Parking Aid Sensor (G254)

• Right Front Center Parking Aid Sensor (G253)

• Right Front Parking Aid Sensor (G252)

• Right Front Parallel Parking Assistance Sensor (G569)

• Removing and installing the Front Parking Aid Sensor and the Parallel Parking Assistance Sensor is performed in the same manner and the following is described for one sensor.

Removing:

CAUTION!
Always follow the sensor removal sequence.

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

Remove the sensor from the bracket and then disconnect the sensor connectors.

- Switch off ignition, switch off all electrical consumers and remove ignition key.

- Remove front bumper cover.

- Release the retaining tabs - arrows - on the sensor bracket and remove the sensor - 1 - from the bumper cover with the connector connected.





• When removing the sensor, make sure that the coupling ring (black silicone ring) remains on the sensor head and does not stick in the bracket or get lost.

• Do not bend the coupling ring.

- Unlatch and disconnect the harness connector - 2 - and remove the sensor - 1 -.





Installing:

CAUTION!
An incorrect or damaged coupling ring can lead to malfunctions.

Do not bend the coupling ring.

Replace damaged coupling rings and ensure the correct ring is installed.

Install in reverse order of removal, noting the following:

• Since the lengths of the sensor heads of the front parking aid and the parallel parking assistance sensors are different, the high coupling rings installed are also different.

- Make sure the correct coupling ring is installed on the sensor head.









- If necessary, replace the sensor coupling ring - 1 -.

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

• Both retaining clips on the sensor holder must engage audibly when installing sensor.

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