Rear view mirror
Automatic antiglare rear view mirrors
The reflection brightness of the exterior
rear view mirrors and the interior rear view
mirror will respond automatically to glare
when

the ignition is switched on, and


incoming light from headlamps falls on
the sensor in the interior rear view mir-
ror
The interior rear view mirror will not react if


reverse gear is engaged


the interior lighting is turned on
Warning!
G
The automatic antiglare function does not
react if incoming light is not aimed directly
at sensors in the interior rear view mirror.
The interior rear view mirror and the exterior
rear view mirrors do not react, for example,
if the cargo compartment is fully loaded.
Glare can endanger you and others.Warning!
G
Exercise care when using the passen-
ger-side exterior rear view mirror. The mirror
surface is convex (outwardly curved surface
for a wider field of view). Objects in mirror
are closer than they appear. Check your in-
side rear view mirror or glance over your
shoulder before changing lanes.
Warning!
G
In the case of an accident, liquid electrolyte
may escape from the mirror housing if the
mirror glass breaks.
Electrolyte has an irritating effect. Do not al-
low the liquid to come into contact with
eyes, skin, clothing, or the respiratory sys-
tem. In case it does, immediately flush af-
fected area with water, and seek medical
help if necessary.

172 Controls in detailDriving systemsRear 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.
1SensorsWarning!
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 247).
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.

174 Controls in detailDriving systemsWarning 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 indicatorAs 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 247).

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.

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 buttons2 and4 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.
iCertain types of garage door openers
are incompatible with the integrated
opener. If you should experience diffi-
culties with programming the transmit-
ter, contact your authorized
Mercedes-Benz Light Truck Center, or
call Mercedes-Benz Customer Assis-
tance Center (in the USA only) at
1-800-FOR-MERCedes, or Customer
Service (in Canada) at
1-800-387-0100.

the following two conditions:
(1) This device may not cause harmful
interference, and
(2) this device must accept any inter-
ference received, including interfer-
ence that may cause undesired
operation.
Any unauthorized modification to this

erased.Reprogramming a single integrated sig-
nal transmitter button
To program a device using a signal trans-
mitter button previously trained, follow
these steps:

Press and hold the desired signal trans-
mitter button (2, 3 or4). Do not re-
lease the button.
