2. Slide the display toward the left side of the vehicle far enough to engage the right end of the display housing into the right end of the display opening in the headliner.
3. Carefully pull down the rear edge of the headliner from the upper liftgate opening header (2) far enough to access the rear park assist display housing.
4. With the display lens held flush against the lower surface of the headliner, position the molded plastic retainer (4) over the display housing with the installation tab oriented towards the rear of the vehicle.
5. Slide the retainer down over the display housing until it is flash with the headliner substrate and the three tabs of the retainer are engaged in the three slots of the display housing.
6. Reconnect the wire harness connector (1) to the connector receptacle on the left end of the display housing.
7. Reinstall the quarter trim panel onto both upper D-pillars. Refer to «INSTALLATION»(ref-306147-S42418312372008120900000) .
8. Reinstall the trim onto the upper liftgate opening. Refer to «INSTALLATION»(ref-306147-S28643076762008120900000) .
9. Reconnect the battery negative cable.

The Park Assist Module (3) is secured with three push-in plastic fasteners through three mounting tabs (2) integral to the module housing to the right inner quarter panel above the right rear wheel housing. The module is concealed beneath the quarter inner trim panel. Concealed within the molded plastic park assist module housing is a microprocessor and the other electronic circuitry of the module. The module housing is sealed to enclose and protect the internal electronic circuitry. The module software is flash programmable.

Two connector receptacles (1) containing terminal pins are integral to the forward-facing side of the housing. The module is connected to the vehicle electrical system through two dedicated take outs and connectors of the body wire harness.

The park assist module cannot be adjusted or repaired and, if damaged or ineffective, it must be replaced.

1. Position the park assist module (2) to the right quarter inner panel (1) behind and above the right rear wheel house, forward of the D-pillar.
2. Secure the module to the right quarter inner panel using three plastic push-in fasteners (3).
3. Reconnect the two body wire harness connectors (4) to the module connector receptacles.
4. Reinstall the trim onto the right quarter inner panel. Refer to «INSTALLATION»(ref-306147-S42418312372008120900000) .
5. Reconnect the battery negative cable.

Scheme 53

Vehicles equipped with the park assist system have four park assist sensors (1) installed on the rear bumper fascia. Only the membrane (3) of each sensor is visible through a hole in the outer vertical surface of the fascia. The remainder of each sensor including the sensor mounting bracket, the sensor spacer and the sensor wiring connection is concealed behind the fascia. A sensor wire harness behind the fascia connects the sensors to the vehicle electrical system.

Each of the four sensors is identical in construction and is interchangeable. The electronic circuitry and a communication chip for each sensor is enclosed and protected within the molded black plastic sensor housing. The housing includes an integral connector receptacle (4) and two integral latch tabs (2). The sensor membrane extends from the surface of the sensor housing, and is finished to match or contrast with the outer surface of the fascia.

Scheme 54

The numbering system for the park assist sensors allows for up to twelve sensors on the vehicle, six front and six rear. The sensors are numbered in a clockwise manner starting at the left front bumper. The left front sensor (if equipped with front park assist) is the number 1 sensor. The numbering continues in a clockwise direction around the vehicle. Since this vehicle uses only four rear sensors, sensor numbers 7 and 12 are omitted, so the left rear sensor is the number 11 sensor.

Scheme 55

A resilient O-ring spacer around the circumference of each of the four sensor membranes (2) isolates the membrane from the openings in the fascia (1). Each sensor is snapped into its own dedicated molded plastic mounting bracket. Each mounting bracket is heat-staked to the back side of the rear fascia.

The park assist sensors cannot be adjusted or repaired. If ineffective or damaged they must be replaced. The sensors and the spacers are each available for individual service replacement.

Note. The park assist sensors (3) and the sensor spacers (O-rings) are each available for separate service replacement. The sensor brackets (5) are bonded to and integral to the back side of the rear bumper fascia (2).

1. Engage the O-ring spacer around the circumference of the sensor membrane protrusion. NOTE: Production and all service replacement O-ring spacers are tapered. The wide side (base) of the O-ring should be seated against the sensor housing and the narrow side should be oriented toward the outer surface of the sensor membrane and the rear fascia.
2. Align and insert the sensor (3) into the sensor bracket (5) on the back of the rear bumper fascia (2) until the bracket latch features (1) are fully engaged over the top and bottom latch tabs of the sensor. Be certain that the sensor membrane is flush with the outer surface of the fascia. NOTE: Be certain that each sensor membrane is properly centered in the openings of the rear fascia and that the O-ring spacers are not pinched. Improper centering or pinched O-rings can be detrimental to proper park assist sensor operation.
3. From the back of the fascia, reconnect the wire harness connector (4) to the sensor connector receptacle.
4. Reinstall the rear wheel flare and the bumper fascia on the same side of the vehicle as the park assist sensor that was serviced. Refer to «INSTALLATION»(ref-306169-S31363497932008120900000) .
5. Reconnect the battery negative cable.

The park assist switch (2) is integral to the instrument panel switch pod (1), which is secured to the instrument panel center bezel just below the heater and air conditioner controls. The park assist switch push button is clearly identified with a white International Control and Display Symbol graphic for Parking Aid and the text OFF . An amber Light Emitting Diode (LED) unit is illuminated behind a small clear plastic jewel-like lens in the push button to give a visual indication whenever the park assist system has been manually disabled with the ignition switch in the ON or START positions. The switch button also has panel lamps dimmer controlled illumination for night visibility.

All of the circuitry and components of the park assist switch are contained within a molded black plastic instrument panel switch pod housing. A single connector receptacle is integral to the back of the switch pod housing. The switch is connected to the vehicle electrical system through a dedicated take out and connector of the instrument panel wire harness.

The park assist switch cannot be adjusted or repaired and, if the switch is ineffective or damaged, the entire instrument panel switch pod unit must be replaced. Refer to REMOVAL .
