Driving systems
Rear Parking AssistThe Rear Parking Assist system is an
electronic aid designed to assist the driver
during parking maneuvers. It visually and
audibly indicates the relative distance
between the rear of the vehicle and an
obstacle.
The Rear Parking Assist system is
automatically activated when you

switch on the ignition
and

move the gear selector lever to reverse
gearR
Warning!G
Rear Parking Assist (rear 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 always remains
with the driver.
Special attention must be paid to objects
with smooth surfaces or low silhouettes
(e.g. trailer couplings, painted posts, or road
curbs). Such objects may not be detected by
the system and can damage the vehicle.
The operational function of the Rear Parking
Assist can be affected by dirty sensors,
especially at times of snow and ice. See
“Cleaning the Rear Parking Assist sensors”
(
page 318).
Interference caused by other ultrasonic
signals (e.g. working jackhammers, car
wash, or the air brakes of trucks) can cause
the system to send erratic indications, and
should be taken into consideration.
Warning!G
Make sure no persons or animals are in the
area in which you are maneuvering. You
could otherwise injure them.

201 Controls in detail
Driving systems
The Rear Parking Assist system monitors
the rear surrounding of your vehicle with
four sensors in the rear bumper.
1SensorsRange of the sensors
To function properly, the sensors must be
free of dirt, ice, snow, and slush. Clean the
sensors regularly, being careful not to
scratch or damage the sensors, see
“Cleaning the Rear Parking Assist sensors”
(
page 318).
!During parking maneuvers, pay special
attention to objects located above or below the
height of the sensors (e.g. planters or trailer
hitches). The Rear Parking Assist system will not
detect such objects at close range and damage
to your vehicle or the object may result.
Ultrasonic signals from outside sources (e.g.
working jackhammers, car wash, or the air
brakes of trucks) may impair the operation of the
Rear Parking Assist system.

Sensors
Minimum distance
If the system detects an obstacle in this
range, all the distance segments in the
warning indicator (
page 202) illuminate
and you hear a warning signal. If the
obstacle is closer than the minimum dis-
tance, the actual distance may no longer
be indicated by the system.Warning indicator
Visual signals indicate to the driver the
relative distance between the sensors and
an obstacle.
The warning indicator is located next to the
tailgate.
Warning indicator
1Distance segments
2Readiness indicatorThe warning indicator is divided into four
yellow, and two red distance segments1.
The Rear Parking Assist system is ready
when you hear a signal and the readiness
indicator2 is illuminated.
As your vehicle approaches an object, one
or more distance segments will illuminate,
depending on the distance. When the sixth
distance segment illuminates, you have
reached the minimum distance.
An intermittent acoustic warning will
sound when the fourth yellow distance
segment illuminates. This signal quickens
with each additional distance segment
illuminated. When all distance segments
illuminate, the acoustic warning becomes
a constant signal. The signal is canceled
when the gear selector lever is moved to
drive positionD or park positionP.

sensors
1Sensors
Use a mild car wash detergent, such as
Mercedes-Benz approved Car
Shampoo, with plenty of water and a
soft, non-scratching cloth to clean
sensors1 on the bumper.
!Only use window cleaning solutions that are
suitable for plastic lamp lenses. Window clean-
ing solutions which are not suitable may damage
the plastic lamp lenses of the headlamps. There-
fore, do not use abrasives, solvents or cleaners
that contain solvents.
Never apply strong force and only use a soft,
non-scratching cloth when cleaning the lenses.
Do not attempt to wipe dirty lenses with a dry
cloth or sponge.
Otherwise you may scratch or damage the lens
surface.
!Do not apply strong pressure to the sensor
covers. Applying strong pressure may damage
the sensor covers.
Follow the instructions provided by the power
washer manufacturer on maintaining a distance
between the vehicle and the nozzle of the power
washer.
!To prevent scratches, never apply strong
force and only use a soft, non-scratching cloth
when cleaning the sensors. Do not attempt to
wipe dirty sensors with a dry cloth or sponge.
