It is not intended to, nor does it replace, the
need for extreme care. The responsibility
during parking and other critical maneuvers

PARKTRONIC is an electronic parking aid with ultrasonic sensors. It indicates visually and audibly the distance between your vehicle and an object.
PARKTRONIC is activated automatically when you:

• shift the transmission to position D, R or
N
• release the parking brake
PARKTRONIC is deactivated at speeds above 11 mph (18 km/h). It is reactivated at lower speeds.
PARKTRONIC monitors the area around your vehicle using six sensors in the front bumper and four sensors in the rear bumper.
