Driving systems
Parktronic system* (Parking assist)
The Parktronic system assists the driver
during parking maneuvers. It visually and
audibly indicates the distance between the
vehicle and an obstacle.
With the ignition on, the Parktronic system
engages automatically at speeds up to ap-
proximately 10 mph (15 km / h) and deac-
tivates during higher speeds.Parktronic system monitors your vehicle’s
environment by means of six sensors in
the front bumper and four sensors in the
rear bumper.
1Sensors located in front bumperWarning!
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.
Make sure that no persons or animals are lo-
cated in the area in which your are maneu-
vering. They could otherwise be injured.
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 Parktronic
system can be affected by dirty sensors, es-
pecially at times of snow and ice. For notes
on cleaning the Parktronic system sensors
(page 237).
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 indicators
The warning indicators show the distance
between the sensor and the obstacle. The
warning indicators for the front area are lo-
cated above the center air vents in the
dashboard. The warning indicator for the
rear area is located in the rear passenger
compartment lamp.
1Segments, left side of vehicle
2Segments, right side of vehicle
Each warning indicator has six yellow and
two red segments.The gear selector lever position deter-
mines which warning indicator is activat-
ed.
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 seg-
ment comes on and a constant acoustic
warning lasting a maximum of
three seconds will sound for the eighth
segment.

After cleaning the sensors, switch
the ignition on.

side of the luggage compartment.
Flip up cover and insert electrical plug
(cigarette lighter type).
Telephone*
Radio transmitters, such as a portable tele-
phone or a citizens band unit, should only
be used inside the vehicle if they are con-
nected to an antenna that is installed on
the outside of the vehicle.
The external antenna must be approved by
Mercedes-Benz. Please contact an autho-
rized Mercedes-Benz Light Truck Center
for information on the installation of an ap-
proved external antenna. Refer to the radio
transmitter operation instructions regard-
ing use of an external antenna.
iThe outlets function even if the key is
not in the ignition.
The electrical outlet can be used to
accommodate electrical consumers
(e.g. air pump, auxiliary lamps) up to a
maximum of 180 W.
If the engine is off, the battery may be-
come discharged if used for long peri-
ods of time.
Warning!
G
Never operate radio transmitters equipped
with a built-in or attached antenna (i.e. with-
out being connected to an external antenna)
from inside the vehicle while the engine is
running. Doing so could lead to a malfunc-
tion of the vehicle’s electronic system, pos-
sibly resulting in an accident and / or serious
personal injury.

Programming or reprogramming the in-
tegrated remote control
Step 1:
Switch on ignition.
Step 2:
If you have previously programmed an
integrated signal transmitter button
and wish to retain its programming,
proceed to step 3. Otherwise, press
and hold the two outer signal transmit-
ter buttons3 and5 and release
them only when the indicator light be-
gins to flash after approximately 20
seconds (do not hold the button for
longer than 30 seconds). This proce-
dure erases any previous settings for
all three channels and initializes the
memory. If you later wish to program a
second and / or third hand-held trans-
mitter to the remaining two signal
transmitter buttons, do not repeat this
step and begin directly with step 3.Step 3:
Hold the end of the hand-held remote
control transmitter1 of the device
you wish to train approximately 2 to
5 in (5 to12 cm) away from the surface
of the integrated remote control locat-
ed on the interior rear view mirror,
keeping the indicator lamp6 in view.
Step 4:
Using both hands, simultaneously
press the hand-held transmitter
button2 and the desired integrated
signal transmitter button (3, 4
or5). Do not release the buttons until
completing step 5.
The indicator lamp6 on the integrat-
ed remote control will flash, first slowly
and then rapidly.
