Overview
The vehicle may be equipped with rear only or front and rear parking aid.
The rear parking aid system sounds a warning through the rear audio speakers (low pitched tone) to alert the driver of stationary objects near the rear bumper when REVERSE is selected. The parking aid system assists the driver in detecting certain objects while the vehicle moves slowly in REVERSE at speeds of less than 4.8 kmh (3 mph). The parking aid system may not detect moving objects.
The front parking aid system sounds a warning through the front audio speakers (high pitched tone) to alert the driver of stationary objects near the front bumper in all transmission positions except PARK or NEUTRAL. The parking aid system assists the driver in detecting certain objects while the vehicle moves at speeds of less than 4.8 kmh (3 mph). The parking aid system may not detect moving objects.
The parking aid system is disabled if a fault is detected in a parking aid sensor, the communications network or the PAM. This is indicated by a parking aid disabled warning message in the message center.
For vehicles with rear parking aid only, the system is enabled and disabled through the message center, located in the IPC. For vehicles with front and rear parking aid, the system is enabled and disabled through the parking aid disable switch. Disabling lasts one key cycle.
For vehicles with rear parking aid only, if a MyKey® restricted key is in use, the parking aid menu is not available in the message center and cannot be deactivated. For vehicles with front and rear parking aid, when a MyKey® restricted key is in use and the parking aid switch is pressed, the message center states, "MyKey Park Aid Cannot Be Deactivated".
