There are two "parking packages": option codes JB6 (with 360 degree camera) and JB7 (without said camera).
From the Equipment book for the JB7:
The parking system is using twelve distance sensors and the revers-ing camera. It supports the driver during the parking procedure, when maneuvering in confined spaces and when driving out of exits.
The parking system ensures greater safety when parking and maneuvering due to:
Visual and acoustic warnings of objects in front of and behind the vehicle as well as at the side of the vehicle
Speed limitation when driving off if obstacles are detected in the direction of travel (Drive Away Assist)
JB7 uses one digital camera on the rear roof end (FR8). Dynamic guide lines are displayed when the reverse gear is engaged and irrespective of the current wheel angle. If the rear door is open, this is indicated in the view.
Additional features:
Parktronic
The Parktronic is an electronic parking aid with ultrasound and uses six distance sensors in the front bumper and six distance sensors in the rear bumper to monitor the vehicle´s surroundings. The Park-tronic provides a visual and acoustic indication of the distance between the vehicle and an obstacle. The volume of acoustic warnings can be adapted in the multimedia system.
Rear Cross Traffic Alert (with code JA7, Blind Spot Assist)
Automatic braking to avoid collision with traffic crossing the vehicle’spath (e.g. vehicles, pedestrians) when reversing. If an object is registered the warning symbol on the corresponding side mirror lights up in red and additionally, an acoustic warning signal occurs. A warning signal appears in the multime-dia system in case of critical situations.
Drive Away Assist
If an obstacle is registered in the driving path, it temporarily limits the driving speed to 1.8 mph (3 km/h). In critical situations a warning symbol is displayed via the multimedia system.
---------------
JB6 adds these camera-related paragraphs:
In addition to twelve distance sensors the 360° camera system has four digital cameras. One camera behind the radiator trim, one in each side mirror housings and one on the rear roof. The parking system uses picture data to generate various views of the vehicle’s surroundings which are shown in real time in the multimedia display. The views can be generated either from one camera or from four cameras. Depending on the view, dy-namic guide lines are displayed to assist the driver. They indicate the path which the vehicle would follow with the current steering wheel angle. The yellow guide lines are automatically adapted as the steering wheel angle changes. The outer guide lines symbolize the vehicle width including the outside mirrors.
Via a switch on the media system the reversing camera can also manually be activated when driving in forward direction at speeds of up to 18 mph (29 km/h). The camera also works with opened rear doors. The cameras cover an area of about 118 inch (3 m) in front and behind, and about 98 inch (2.5 m) to the left and right side of the vehicle.
JB6 requires F64 and is only available for vehicles below 10,000lbs.
------------------
F64 are the electrically-retracting side mirrors:
The electrically foldable mirrors, are only available in conjunction with the adjustable and heated exterior mirrors (F68) for vehicles up to 10,000 lbs. They can be operated using the button located in the control panel on the driver’s door. The side mirrors can be conveniently folded when parking, and driving through a narrow road or car wash facility preventing any potential damage.
