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.

malfunction
If no distance segments illuminate and no
acoustic warning sounds, there is a mal-
function in the Rear Parking Assist system.
Have the Rear Parking Assist system
checked at an authorized
Mercedes-Benz Light Truck Center as
soon as possible.
Rear view camera
Warning!G
The rear view camera is only an aid and may
display obstacles from a distorted perspec-
tive or inaccurately, or may not display ob-
stacles at all. The rear view camera does not
relieve you of the responsibility to be cau-
tious, take care and pay careful attention.
The rear view camera may not show objects
which are

very close to the rear bumper

under the rear bumper

under the spare wheel

nearby behind the spare wheel
You are responsible for safety at all times
and must continue to pay attention to the
immediate surroundings when parking and
maneuvering. This includes the area behind,
in front of and beside the vehicle. Otherwise
you could endanger yourself or others.
Warning!G
Make sure that no persons or animals are in
or near the area in which you are
parking/maneuvering. Otherwise, they
could be injured.
Warning!G
The rear view camera either will not function
or will not function to its full capability if

the tailgate is open

it is raining very hard, snowing or foggy

it is night or you are parking/maneuver-
ing your vehicle in an area where it is
very dark

the camera is exposed to a very bright
white light

the immediate surroundings are illumi-
nated with fluorescent light (the display
may flicker)

The rear view camera is an optical parking
aid. It shows you the area behind the
vehicle in the COMAND system display
when reverse gearR is engaged, for
example during parallel parking.
To function properly, the camera lens must
be free of dirt, ice, snow, and slush. Clean
the camera lens regularly, being careful
not to scratch or damage the camera lens,
see “Cleaning the rear view camera lens”
(
page 319).The rear view camera is on the tailgate
above the rear window wiper.

In this case, have the position and
setting of the camera checked by a
qualified specialist workshop.
Mercedes-Benz recommends that you
contact a Mercedes-Benz Light Truck
Center for this purpose.

Split rear seat bench
Warning!G
Do not load items on the roof. It may cause
instability during some maneuvers which
could result in an accident.
Warning!G
Always lock seat backrest in its upright
position when rear seat bench is occupied
by passengers, or cargo is being carried
behind the rear seat bench.
To help avoid personal injury from smaller
objects being thrown around in the occu-
pant compartment during a collision or
sudden maneuver, always use partition net*
when transporting cargo (
page 210).
Always use the cargo tie down rings
(
page 209).
Warning!G
Failure to assure that seat benches and seat
backrests are locked into place could result
in an increased chance of injury in an acci-
dent.
Never place hands under seat or near any
moving parts while a seat is being adjusted.
For safety reasons, the rear seat bench
must only be adjusted when the vehicle is
stationary.
Never drive vehicle with the tailgate open.
Deadly carbon monoxide (CO) gases may
enter vehicle interior resulting in uncon-
sciousness and death.
!Before folding the rear seat backrest and
