The Parktronic system assists the driver during parking 
maneuvers. It visually and audibly indicates the relative 
distance between the vehicle and an obstacle.
The front area of the vehicle is monitored when driving 
forward. When reversing or with the gear selector lever 
in position “N”, the front as well as the rear areas are 
monitored.
With the electronic key in starter switch position 2, 
Parktronic engages automatically at speeds up to 
approximately 10 mph (15 km/h) and deactivates during 
higher speeds.
Parktronic can be switched off by a control switch 
located in the center console. It engages automatically 
again when starting the engine.
See page 283 for parktronic switch.
Wa r n i n g !
Parktronic is a supplemental system. It is not 
intended to nor does it replace the need for extreme 
care. The responsibility during parking and other 
critical maneuvers rests always with the driver.Special attention must be paid to objects having 
smooth surfaces or low silhouettes (e.g. trailer 
couplings, painted posts, or street curbs). Such 
objects may not be detected by the system and can 
damage the vehicle.The operational function of the Parktronic can be 
affected by dirty sensors, especially at times of 
snow and ice. See page 378 for notes on cleaning 
the parktronic system sensors.Interference caused by other ultrasonic signals 
(e.g. working jackhammers or the air brakes of 
trucks) can cause the system to send erratic 
indications, and should be taken into 
consideration.
