Rear Parking Assist*
The Rear Parking Assist system is an elec-
tronic aid designed to assist the driver dur-
ing parking maneuvers. It visually and
audibly indicates the relative distance be-
tween the rear of the vehicle and an obsta-
cle.
The Rear Parking Assist system is auto-
matically activated when you switch on the
ignition and shift the gear selector lever to
positionR.The Rear Parking Assist system monitors
the rear area of your vehicle by means of
four sensors in the rear bumper.
1Sensors
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 rests with
the driver.
Special attention must be paid to objects
with smooth surfaces or low silhouettes
(e.g. trailer couplings, painted posts, or
street curbs). Such objects may not be de-
tected by the system and can damage the
vehicle.
The operational function of the Rear Parking
Assist can be affected by dirty sensors, es-
pecially at times of snow and ice. See
“Cleaning the Rear Parking Assist sensors”
(
page 286).
Interference caused by other ultrasonic sig-
nals (e.g. working jackhammers or the air
brakes of trucks) can cause the system to
send erratic indications, and should be tak-
en into consideration.
Warning!G
Make sure no persons or animals are in the
area in which you are maneuvering. You
could otherwise injure them.

Range 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 them.Minimum distance
The minimum distance between the sen-
sors and an obstacle is approximately
20 in (50 cm). If you encounter an obstacle
in this range, all the warning lamps come
on and you hear a warning signal. If the ob-
stacle is closer than the minimum dis-
tance, the actual distance may no longer
be indicated by the system. Centerapprox. 59.1 in (150 cm)
Cornersapprox. 40 in (100 cm)
!
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 dam-
age to your vehicle or the object may
result.
Ultrasonic signals from outside sourc-
es (e.g. truck air brakes or jackham-
mers) may impair the operation of the
Rear Parking Assist system.

Warning indicator
Visual signals indicate to the driver the rel-
ative distance between the sensors and an
obstacle. The warning indicator is located
next to the tailgate.
Warning indicator
As your vehicle approaches an object, one
or more segments will come on, depending
on the distance. When the sixth segment
lights, you have reached the minimum dis-
tance.An intermittent acoustic warning will
sound when the first yellow segment
comes on. This signal quickens with each
additional segment lit. When all segments
illuminate, the acoustic warning becomes
a constant signal. The signal is canceled
when the gear selector lever is placed in
position D or P.
Rear Parking Assist malfunction
There is a malfunction in the Rear Parking
Assist system if:

a low warning tone sounds while the
vehicle is reversing
The Rear Parking Assist sensors are
dirty or malfunctioning.
Clean the Rear Parking Assist sys-
tem sensors (
page 286).
Switch on the ignition again.

no segments come on and no warning
sounds
The Rear Parking Assist is malfunction-
ing.
Have the Rear Parking Assist sys-
tem checked by an authorized
Mercedes-Benz Light Truck Center
as soon as possible.
Malfunction may also be caused by inter-
ference from other radio or ultrasonic sig-
nals.
Check the Rear Parking Assist opera-
tion at another location to rule out in-
terference from outside radio or
ultrasonic signals.

Vehicle care
Cleaning the Rear Parking Assist
sensors*
1Sensor
Use a mild car wash detergent, such as
Mercedes-Benz approved Car
Shampoo, with plenty of water to
clean sensors1.
To prevent scratches, never apply strong
force and use only a soft, non-scratchy
cloth when cleaning the sensors. Do not
attempt to wipe dirty sensors with a dry
cloth or sponge.Wiper blades
Fold wiper arms forward.
Clean the wiper blade inserts with a
clean cloth and detergent solution.Window cleaning
Fold wiper arms forward.
Use a window cleaning solution on all
glass surfaces.
An automotive glass cleaner is recom-
mended.
Warning!G
For safety reasons, switch off wipers and re-
move SmartKey from starter switch before
cleaning the wiper blades. Otherwise, the
wiper motor can suddenly turn on and cause
injury.
!
Fold the windshield wiper arms back
onto the windshield before turning the
SmartKey in the starter switch.
Hold on to the wiper when folding the
wiper arm back. If released, the force
of the impact from the tensioning
spring could crack the windshield.
