Parking assist (Parktronic)
(optional)
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, the front as well as the rear
areas are monitored.
With the electronic key in steering lock 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 238 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 317 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.

1Sensors located in bumper
(front bumper shown)A total of 10 sensors (1) monitor the vehicle’s front and
rear areas. Six sensors are located in the front bumper,
four sensors in the rear bumper.
For proper operation of the Parktronic always keep the
sensors clean, especially at times of snow and ice.
See page 317 for instructions on cleaning the sensors in
the bumpers.

Warning indicators
1Frame
2SegmentsVisual and audible signals indicate to the driver the
relative distance between the vehicle and an obstacle.
Warning indicators for the front area are located above
the center air outlets in the dashboard.
Warning indicators for the rear area are located in the
rear passenger compartment lamp.
The frames are illuminated when the Parktronic is
engaged.
Each warning indicator has 6 yellow and 2 red
segments.
As soon as the sensors detect an obstacle, one or more
segments light up, depending on the distance. An
intermittent acoustic warning will also sound as the
seventh segment lights up and a constant acoustic
warning lasting a maximum of 3 seconds will sound for
the eighth segment.

The obstacle may not be recognized if outside the
shaded sensor field, and no longer be indicated when
approaching it any closer (warning indicators go out).
Parktronic malfunction
All red segments of the warning indicators light up, and
a warning sounds for 3 seconds, if Parktronic does not
function properly.
A dirty sensor could be the reason. (See page 317 for
instructions on cleaning the sensors in the bumpers.)
After cleaning the sensors, turn electronic key in
steering lock to position 2. If the defect continues to be
displayed, have the system checked at your authorized
Mercedes-Benz Center.Parktronic switch
