and 55 mph (88 km/h) for approximately
20 seconds
Warning!
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
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 road
curbs). Such objects may not be detected by
the system and can damage the vehicle.
The operational function of the Parktronic
system can be affected by dirty sensors,
especially at times of snow and ice. See
“Cleaning the Parktronic system sensors”
(page 408).
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.

Minimum distance
If the system detects an obstacle in this
range, all the distance warning segments
illuminate and you hear a warning signal. If
the obstacle is closer than the minimum
distance, the actual distance may no
longer be indicated by the system.Warning indicators
Visual signals indicate to the driver the rel-
ative distance between the sensors and an
obstacle. The warning indicator for the
front area is located above the center air
vents in the dashboard. The warning indi-
cator for the rear area is located in the rear
passenger compartment under the roof.

Driving systems
Each warning indicator is divided into five
yellow and two red distance segments for
either side of the vehicle. The Parktronic
system is operational when the readiness
indicators3 are illuminated.
The current transmission position deter-
mines which warning indicator will be acti-
vated.As your vehicle approaches an object, one
or more distance segments will illuminate,
depending on the distance. When the red
distance segment illuminates, you have
reached the minimum distance.


Front area: An intermittent acoustic
warning lasting a maximum of
2 seconds will sound as the first red
distance segment illuminates and a
constant acoustic warning lasting a
maximum of 2 seconds will sound for
the second red distance segment. The
signal is canceled when the automatic
transmission is set to positionP, or the
parking brake is set.


Rear area: An intermittent acoustic
warning lasting a maximum of
2 seconds will sound as the first red
distance segment illuminates and a
constant acoustic warning lasting a
maximum of 2 seconds will sound for
the second red distance segment. The
signal is canceled when the automatic
transmission is set to positionD, P, or
the parking brake is set.Switching the Parktronic system*
on/off
You can switch off the Parktronic system
manually.

If only the red distance segments illumi-
nate and an acoustic warning sounds,
there is a malfunction in the Parktronic
system. The Parktronic system will auto-
matically switch off after 20 seconds and
the indicator lamp in the Parktronic switch
comes on.

Have the Parktronic system checked
by an authorized Mercedes-Benz Light
Truck Center as soon as possible.
If only the red distance segments illumi-
nate and no acoustic warning sounds, the
Parktronic system sensors are dirty (e.g.
slush, snow or ice) or there is an interfer-
ence from other radio or ultrasonic signals
(e.g. working jackhammers, car wash or
the air brakes of trucks). The Parktronic
system will automatically switch off after
20 seconds and the indicator lamp in the
Parktronic switch comes on.

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

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)


there is a sudden change in tempera-
ture, e.g. if you drive into a heated ga-
rage from the cold (lens condensation)


the camera lens is dirty or covered


the rear of your vehicle is damaged
In this case, have the position and set-
ting of the camera checked by a quali-
fied specialist workshop.
Mercedes-Benz recommends that you
visit a Mercedes-Benz Light Truck

Warning!
G
Always fasten items being carried as secure-
ly as possible using cargo tie-down rings and
fastening materials appropriate for the
weight and size of the load.
In an accident, during hard braking or sud-
den maneuvers, loose items will be thrown
around inside the vehicle, and can cause in-
jury to vehicle occupants unless the items
are securely fastened in the vehicle.
To help avoid personal injury during a colli-
sion or sudden maneuver, always use tie
down rings, and if so equipped, always use
partition net* when transporting cargo.
Never drive vehicle with the tailgate open.
