1. Consumables

Adhesive tape.

degreasing product(index "J1") .

2. Overview of the various parking assistance sensors

The parking assistance sensors consist of the following sensors :

• Proximity sensors
• Parking space measurement sensors
• Blind spot monitoring sensors

3. Operating conditions of the parking assistance sensors

Detection is performed by means of a highly sensitive membrane " a".

The sensitivity of the diaphragm can be altered by an inappropriate covering.

Detection is then inaccurate or non-existent.

4. General

4.1. Vehicles fitted with unpainted parking assistance sensors

The unpainted parking assistance sensors must never be covered with paint.

When touching up the paintwork on the bumper, remove or cover the parking assistance sensors.

4.2. Vehicles fitted with painted parking assistance sensors

CAUTION : To ensure that obstacle detection is not incorrect or non existent : Special "to be painted" proximity sensors must only be covered with a coat of paint with a maximum thickness of 120 microns.

Protect the parking assistance sensors (1), (2)  (at "b") ; Using adhesive tape.

A paint thickness greater than 120 microns will lead to operating problems :

• No detection
• Incorrect indication given to the driver

5. Painting

5.1. New panels

The "to be painted" type parking assistance sensors are prepared in order to be coated directly with finishing paint.

The new parking assistance sensors are supplied with a 25-micron-thick coat of primer.

5.2. Painting of a new "to be painted" type parking assistance sensor

Degrease the surface ; Using a degreaser(index "J1") .

Wipe with a clean, dry, lint-free cloth.

Paint the parking assistance sensor.

N.B. : The thickness must not exceed 120 microns.

5.3. Touching up paint on bumpers

CAUTION : Never apply another coat of paint to a parking assistance sensor that already has one coat of finishing paint . Remove or mask the parking assistance sensors before applying the paint.

6. Paintwork defects causing parking assistance sensor malfunctions

Too much paint on the diaphragm.

Presence of a paint run in the peripheral groove of the diaphragm.

7. Additional operation

Check the operation of the parking assistance sensors ; Using the diagnostic tool.
