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.

FloormatsTelephone*
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.
Warning!G
Whenever you are using floormats, make
sure there is enough clearance and the
floormats are securely fastened.
Floormats should always be securely fas-
tened using the eyelets and retainer pins.
Before driving off, check that the floormats
are securely in place and adjust them if nec-
essary. A loose floormat could slip and
hinder proper functioning of the pedals.
Do not place several floormats on top of
each other as this may impair pedal move-
ment.
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
personal injury.
Warning!G
Please do not forget that your primary re-
sponsibility is to drive the vehicle. A driver’s
attention to the road must always be
his /her primary focus when driving. For
your safety and the safety of others, we rec-
ommend that you pull over to a safe location
and stop before placing or taking a tele-
phone call.
If you choose to use the telephone
1 while
driving, please use the hands-free device
and only use the telephone when road, traf-
fic and weather conditions permit. Some ju-
risdictions prohibit the driver from using a
cellular telephone while driving a vehicle.
Only operate the COMAND (Cockpit
Management and Data System)
1 if road,
traffic and weather conditions permit.
Bear in mind that at a speed of just 30 mph
(approximately 50 km / h), your vehicle is
covering a distance of 44 feet
(approximately 14 m) every second.

Exact location and color of the button
may vary by garage door opener brand.
Depending on manufacturer, the “train-
ing” button may also be referred to as
“learn”or “smart” button. If there is dif-
ficulty locating the transmitting button,
refer to the garage door opener opera-
tor’s manual.
Step 9:
Press “training” button on the garage
door opener motor head unit.
The “training light” is activated.
You have 30 seconds to initiate the follow-
ing step.
Step 10:
Firmly press, hold for two seconds and
release the programmed integrated
signal transmitter button (2, 3,
or4).
Step 11:
Press, hold for two seconds and re-
lease same button a second time to
complete the training process.Some garage door openers (or other rolling
code equipped devices) may require you to
perform this procedure a third time to
complete the training.
Step 12:
Confirm the garage door operation by
pressing the programmed integrated
signal transmitter button (2, 3,
or4).
Step 13:
To program the remaining two buttons,
repeat the steps above starting with
step 3.
Gate operator/Canadian programming
Canadian radio-frequency laws require
transmitter signals to “time-out” (or quit)
after several seconds of transmission
which may not be long enough for the inte-
grated signal transmitter to pick up the sig-
nal during programming. Similar to this
Canadian law, some U.S. gate operators
are designed to “time-out” in the same
manner. If you live in Canada or if you are having dif-
ficulties programming a gate operator (re-
gardless of where you live) by using the
programming procedures, replace step 4
with the following:
Step 4:
Continue to press and hold the inte-
grated signal transmitter button (2,
3, or4) while you press and re-press
(“cycle”) your hand-held remote con-
trol transmitter6 every two seconds
until the frequency signal has been
learned. Upon successful training, the
indicator lamp1 will flash slowly and
then rapidly after several seconds.
Proceed with programming step 5 and
step 6 to complete.
