Visual Park Aid Alert
NOTE: The on-screen alert color transitions may not match changes in the audible parking aid alert tone frequency.
The visual park aid alert feature displays red, yellow or green visual alerts that appear as highlights over the video image 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 PAM to generate the visual highlights over the video image. When the reverse gear is selected and an object is detected by a parking aid sensor, the parking aid sensor data message is sent from the PAM through the HS-CAN1 to the BCM, which sends the message to the rear parking aid camera via the LIN circuit.
Visual highlights color chart
NOTE: The on-screen alert color transitions may not match changes in the audible parking aid alert tone frequency.
Distance Zone | Color |
|---|---|
0 – 17 in (0 – 45 cm) | Red |
18 – 41 in (46 – 105 cm) | Yellow |
42 – 71 in (106 – 180 cm) | Green |
72 + in (181 + cm) | No highlight |
If the visual park aid alert feature is enabled, the feature is still operational even if the audible rear parking aid system has been disabled by the driver.
Fixed Guidelines
NOTE: 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.
The rear parking aid camera fixed guidelines feature displays guidelines on top of the video image as projection of the wheel tracks or vehicle corners to assist the driver with alignment of the vehicle. A black dashed line on the
