Collision Avoidance and Parking Assist Systems: Description and Operation






Parking Aid

Familiarity with the function and operation of the parking system is essential in the event of customer concerns. Refer to the Owner's Manual.

The parking aid system, or PDC (Park Distance Control), supports the driver while parking by indicating acoustically the distance to an obstruction behind the vehicle.

The 4-channel parking aid system consists of:

Parking Aid Control Module (J446)

Rear Parking Aid Warning Buzzer (H15)

Left Rear Center Parking Aid Sensor (G204)

Left Rear Inner Parking Aid Sensor (G334)

Right Rear Inner Parking Aid Sensor (G335)

Right Rear Center Parking Aid Sensor (G205)

Function:

Shift into the Reverse gear to switch it on. To switch it off, drive faster than 10 mph (15 km/h).

A brief signal tone will sound when the parking aid is ready. If there is a malfunction in the system, a tone will sound for 5 seconds.

During the distance measurement, the pauses between chime impulses get shorter as the gap between vehicles gets smaller. At proximity of less than 30 cm, a continuous tone is heard. Exception: Driving parallel with a wall = no warning

DTC recognition and display

The parking aid system is capable of On Board Diagnostic.

Use Guided Fault Finding.

Parking Aid Sensor, Painting

If a new parking aid sensor is installed, the sensor head must first be painted to match the color of the bumper cover. The following requirements must be observed when painting the sensors to ensure the parking aid system will work correctly.

Painting Sensor

- Remove the coupling ring (black silicone ring) from the sensor head.

- Remove grease from the black sensor head - 1 - in the area to be painted - 2 - with isopropyl alcohol.





- Paint sensor in the area to be painted - 2 - in the color of the bumper cover.

Paint application dimension - B - is 3 mm (+ maximum 2 mm).

- After the paint has dried, attach the coupling ring (black silicone ring) to the sensor head.

CAUTION!
Do not bend the coupling ring.

Using a damaged coupling ring can cause malfunctions.

Replace damaged coupling rings.
