Driving with DISTRONIC Plus
This section describes a number of driving
situations where special precaution is re-
quired on the part of the driver. Be pre-
pared to brake in such situations. Braking
will deactivate the DISTRONIC Plus sys-
tem.
The most likely cause for a malfunctioning
system is a dirty sensor (located behind
the hood grille), especially at times of snow
and ice or heavy rain. In such a case,
DISTRONIC Plus will switch off, and the
message:“DISTRONIC PLUS
currently unavailable
See Oper. Manual”
appears in the multifunction display.
For cleaning and care of the
DISTRONIC Plus sensor, see “Cleaning the
DISTRONIC Plus*/ PRE-SAFE
® Brake* sys-
tem sensors (USA only)”(
page 558).
Another cause might be that the radar sen-
sors have been manually switched off in
the instrument cluster control system.
Please verify that the radar sensors are
switched on (
page 272).
Warning!G
DISTRONIC Plus works to maintain the
speed selected by the driver unless a mov-
ing obstacle proceeding directly ahead of it
in the same travel direction is detected (e.g.
following another vehicle ahead of you at
your set distance).
This means that:

Your vehicle can pass another vehicle
after you change lanes.

While in a sharp turn or if the vehicle in
front is in a sharp turn, DISTRONIC Plus
could lose sight of a vehicle traveling in
front of it, then your vehicle could accel-
erate to the previously selected speed.
DISTRONIC Plus regulates only the distance
between your vehicle and those directly
ahead of it. It may not register stationary ob-
jects in the road, e.g.:

a stopped vehicle in a traffic jam

a disabled vehicle

an oncoming vehicle
The driver must always be alert, observe all
traffic and intercede as required by means
of steering or braking the vehicle.
Warning!G
DISTRONIC Plus should not be used in
snowy or icy road conditions.
iIf the message:
“DISTRONIC PLUS
currently unavailable
See Oper. Manual”
disappears during driving and the last speed
stored flashes for approximately 5 seconds, the
dirt (e.g. slush) has dissolved; DISTRONIC Plus is
available again.

Dynamic Rear View Monitor*
The Dynamic Rear View Monitor is an elec-
tronic and visual parking aid. It shows you
the area behind the vehicle on the
COMAND display.
In addition, the Dynamic Rear View Moni-
tor contains guide lines to help you with re-
verse parking (back-in parking) and
parallel parking.
The area behind the vehicle is displayed as
a reverse-mirror image similar to the view
in a rear-view mirror.The Dynamic Rear View Monitor is in the
handle strip of the trunk lid.

called “Park Assist” in COMAND display.

Warning!G
Please note that objects which do not touch
the ground, such as the bumper of a vehicle
parked behind you, a trailer hitch, or the
back of a truck, may appear to be further
away than they actually are. In this case, you
should not use the guide lines to judge dis-
tance. The use of the guide lines to judge
distance increases the risk of impacting the
objects.
Warning!G
The Dynamic Rear View Monitor is a supple-
ment system. It is not intended to, nor does
it replace, the need for extreme care. The re-
sponsibility during parking and other driving
maneuvers always remains with the driver.
The Dynamic Rear View Monitor may show
obstacles with a distorted perspective, in-
correctly or not at all.
Special attention must be paid to objects
outside of the camera’s field of view such as
those located very close to or below the rear
bumper, or above the recessed grip of the
luggage compartment lid. Such objects may
not be detected by the system and can dam-
age the vehicle.
The Dynamic Rear View Monitor does not
warn you about impending collisions with
objects. The driver is always responsible for
safety and must continue to pay attention to
the immediate surroundings while parking
or maneuvering the vehicle. This applies not
only to the area behind the vehicle, but also
to the area in front of and to the sides of the
v e h i c l e . F a i l u r e t o d o s o c o u l d r e s u l t i n i n j u r y
to persons and/or damage to the vehicle or
other property. We also recommend that the
driver use the Parktronic system* or Park
Assist* when parking or maneuvering the
vehicle.Warning!G
Make sure no persons or animals are in the
area in which you are maneuvering. You
could otherwise injure them.
Warning!G
The Dynamic Rear View Monitor may not
function if:

the trunk lid is not completely closed

it is raining or snowing heavily, or if
there is thick fog

in a very dark area

the camera is exposed to very strong
white light (white stripes may appear on
the COMAND display)

the surrounding area is lit with fluores-
cent light (the COMAND display can
flicker)

outside temperatures are very high (lens
condensation)

(reverse gear).
The COMAND display will show the
area behind the vehicle with guide lines
to help you reverse into a parking
place.Reverse parking (back-in parking)
This function helps you when you are re-
versing in a straight line or backing in at
any angle.
The space required by the vehicle for re-
versing is shown by guide lines.
When you turn the steering wheel to a
straight-ahead position, you will see the
guide lines on the COMAND display in the
following order:

there is a sudden change in tempera-
ture, for example when you drive out of
the cold into a heated garage in winter
(lens condensation)

the camera lens is dirty or covered, see
“Cleaning the Dynamic Rear View
Monitor lens*” (
page 560)

the rear of your vehicle is damaged. In
this case, have the position and setting
of the camera checked by a qualified
technician. Contact an authorized
Mercedes-Benz Center.
Do not use the Dynamic Rear View Monitor
if the roads are icy, slippery or covered with
snow. The vehicle could slip causing the ac-
tual vehicle position to deviate from the one
shown on the COMAND display.
This may cause injury to you or others, or
damage the vehicle or objects.
Mounting tires/rims of other specification
than the original equipment tires/rims may
impair the function of the Dynamic Rear
View Monitor. Contact an authorized
Mercedes-Benz Center.
Warning!G
Use of Dynamic Rear View Monitor can be
dangerous if you are color-blind or have im-
paired color vision.
Only use Dynamic Rear View Monitor if you
can see and distinguish all colored guide
lines shown by Dynamic Rear View Monitor
on the COMAND display.
iThe Dynamic Rear View Monitor must be ac-
tivated in the instrument cluster control system
in order for it to be switched on (
page 269).
iIf you activate a different function on the
driver’s COMAND controls while reverse parking
or parallel parking, the image from the back-up
camera is interrupted.
To reactivate the camera, take the vehicle out of
reverse gear and then re-engage reverse gear
again.

Night View Assist*
Night View Assist illuminates the road with
infrared light in addition to the normal
headlamps.
A camera at the top of the windshield mea-
sures the infrared light and shows a
black-and-white image on the multifunc-
tion display. The image on the multifunction display cor-
responds to a road lit up by high-beam
headlamps.
The Night View Assist image on the multi-
function display is not impaired

by the headlamps of approaching vehi-
cles

if you cannot switch on the high beams
due to oncoming traffic
As a result, you can better follow the
course of the road and detect obstacles
earlier on.The camera is at the top of the windshield.
1Night View Assist camera
Warning!G
Night View Assist is only an aid to support
you while driving and cannot substitute your
careful attention. Do not rely on the display
of the Night View Assist; instead, continue
to look through the windshield. You are al-
ways responsible for safety and must drive
in accordance with traffic conditions. Other-
wise, you could endanger yourself and oth-
ers.
If it is foggy, raining or snowing, the clarity of
the Night View Assist image on the multi-
function display may be diminished.Warning!G
Night View Assist cannot record objects im-
mediately in front of or next to the vehicle.
When maneuvering, continue to look
through the windshield. Make sure no per-
sons or animals are in the area in which you
are maneuvering. You could otherwise in-
jure them.
iInfrared light is invisible to the human eye
and can therefore remain permanently switched
on without blinding oncoming traffic.
