Rear Only Parking Aid Camera
The rear parking aid camera is located on the decklid. The rear camera communicates with the APIM through a coaxial cable in a digital serial format (LVDS).
Visual Park Aid Alert
The visual park aid alert feature displays a visual highlight in the zone where an object has been detected by the rear parking aid system. This feature utilizes the parking aid sensor data from the IPMA to generate the visual highlights on the video image. When reverse (R) is selected and an object is detected by a rear parking aid sensor, the parking aid sensor data message from the IPMA is used by the APIM to generate the alert.
If the visual park aid alert feature is enabled, the feature is still operational even if the rear parking aid system has been disabled by the driver.
The on-screen alert transitions may not match changes in the audible parking aid alert tone frequency.
Fixed Guidelines
The rear parking aid camera fixed guidelines feature displays guidelines on top of the video image to assist the driver with alignment of the vehicle. A dashed line on the displayed image represents the center of the vehicle and 3 color-coded lines identify different zones between the rear of the vehicle and objects. The rear parking aid camera generates the fixed guidelines over the video image.
The guidelines are not shown when reverse (R) is not selected (video delay active).
Fixed guidelines are not shown when the decklid is open.
The color-coded lines cannot indicate accurate or consistent distances between the rear of the vehicle and objects shown in the video image. This normal condition is due to variances in vehicle ride height including, but not limited to vehicle loading.
Active Guidelines
The active guidelines feature displays dynamic guidelines that correspond to the projected path of vehicle travel, based on the current steering angle. Several modules are involved in generating the steering angle data used to support the active guidelines. The PSCM monitors the steering angle sensor and sends the steering wheel angle sensor data to the ABS module. The ABS module uses this message from the PSCM to generate the steering angle message that is sent to the GWM. The GWM then sends the message to the APIM. The rear parking aid camera uses this data to generate the active guidelines over the video image.
If the steering wheel is in the straight-ahead position or if the liftgate is open, the active guidelines are not shown.
The guidelines are not shown when reverse (R) is not selected (video delay active).
If the battery has been disconnected or discharged, or a module is disconnected or replaced, the active guidelines may be inoperative until the vehicle is driven on a flat and smooth road at 32 km/h (20 mph) or more, with hands placed loosely on the steering wheel and minimal steering correction for approximately 30 seconds. If the guidelines remain inoperative, it may be necessary to disconnect the battery for 5 minutes with the driver's door open, then drive the vehicle for 8 kilometers (5 miles) in normal city driving before performing the procedure described above.
Manual Zoom
The manual zoom feature is generated by the rear parking aid camera. If the manual zoom feature is on and the vehicle is shifted out of reverse (R), the manual zoom feature is disabled and must be re-enabled the next time reverse (R) is selected.
To turn the manual zoom feature on and off, the driver uses an on-screen button located on the audio system display while in reverse (R). The driver generated commands originate at the audio system display, which is sent to the APIM. The APIM zooms the image from rear parking aid camera.
Video Delay
When the video delay is turned on, the APIM keeps the rear video display enabled after the transmission is shifted out of reverse (R) into any gear other than park (P), until the vehicle speed reaches 8 km/h (5 mph). When the delay is off (default), the rear video image display remains until the transmission is shifted from reverse (R) to any other gear shift position.
