388 Controls in detailDriving systemsWhen DISTRONIC Plus detects a vehicle
driving ahead of you, the ring on the speed-
ometer dial lights up between the speed of
the vehicle ahead of you and set speed2.
If DISTRONIC Plus calculates that there is
a danger of collision (
page 397):
The distance warning lampl in the
instrument cluster comes on.
An intermittent warning sounds.
Immediately brake the vehicle to avoid
a collision.
Under no circumstances should the
driver await the intermittent warning
sound before braking. See the follow-
ing warning note.
The intermittent warning sound ceases
and the distance warning lampl
goes out when the necessary distance
to the vehicle ahead is again
established.
Warning!
G
An intermittent warning sounds and the dis-
tance warning lampl in the instrument
cluster is illuminated if the DISTRONIC Plus
system calculates that the distance to the
vehicle ahead and your vehicle’s current
speed indicate that DISTRONIC Plus will not
be capable of slowing the vehicle sufficiently
to maintain the preset following distance,
which creates a danger of a collision.
Immediately brake your vehicle to increase
the distance between your vehicle and the
vehicle in front of you. The warning sound is
intended as a final caution that you have not
interceded with your own braking inputs to
avoid a potentially dangerous situation. Do
not wait for the operation of the warning sig-
nal to intercede with your own braking, as
that will result in potentially dangerous
emergency braking which will not always re-
sult in an impact being avoided.
Tailgating increases the risk of an accident.
Warning!
G
DISTRONIC Plus brakes your vehicle with a
maximum of 13 ft/s
2 (4 m/s
2). This corre-
sponds to about 40% of the maximum decel-
eration ability of your vehicle.
DISTRONIC Plus brakes the vehicle in an ef-
fort to restore the preset distance or to
maintain the speed. The brake pedal is auto-
matically applied as this happens which re-
sults in the brake pedal moving.
Keep driver’s foot area clear at all times, in-
cluding the area under the brake pedal. Ob-
jects stored in this area may impair pedal
movement which could interfere with the
braking ability of the DISTRONIC Plus sys-
tem.
Do not place your foot under the brake pedal
– your foot could become caught.

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
in the instrument cluster. The warning indi-
cator for the rear area is on the roof liner in
the rear.
1Left side of the vehicle
2Right side of the vehicle
3Indicator
Each warning indicator is divided into five
yellow and two red distance segments for
either side of the vehicle.
If yellow indicators 3 under the segments
are lit, Park Assist is ready to measure.The position of the gear selector lever de-
termines which warning indicators will be
activated.
As your vehicle approaches an object, one
or more distance segments will illuminate,
depending on the distance. When the sev-
enth distance segment illuminates, you
have reached the minimum distance.
Front area:
As soon as the first red segment lights
up, you will hear an intermittent warn-
ing tone for approx. two seconds. Once
the second red segment lights up, you
will hear a continuous warning tone.
You have reached the minimum dis-
tance.
Rear area:
As soon as the first red segment lights
up, you will hear an intermittent warn-
ing tone for approx. two seconds. Once
the second red segment lights up, you
will hear a continuous warning tone.
You have reached the minimum dis-
tance.

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 rests 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
vehicle. Failure to do so could result in injury
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 that no persons or animals are
standing in the area where you are maneu-
vering. 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)
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)
outside temperatures are very high (lens
condensation)
the camera lens is dirty or covered, see
“Cleaning of the Dynamic Rear View
Monitor lens*” (
page 538)
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.
420 Controls in detailDriving systemsNight 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 that no
persons or animals are in or near the area in
which you are maneuvering.
i
Infrared light is invisible to the human eye
and can therefore remain permanently switched
on without blinding oncoming traffic.

G
When closing the tilt/sliding sunroof, make
sure that there is no danger of anyone being
harmed by the closing procedure.
If the tilt/sliding sunroof encounters an ob-
struction that blocks its path in a circum-
stance where you are closing the tilt/sliding
sunroof by moving the tilt/sliding sunroof
switch past the resistance point, or by
pressing and holding button‹on the
SmartKey, by pressing and holding the sen-
sor surface (vehicles with KEYLESS-GO*) on
the outside door handle, the automatic re-
versal function will not operate.

ed by releasing the switch or, if the switch
was moved past the resistance point and re-
leased, by moving the switch in any direc-
tion.
The tilt/sliding sunroof is made out of glass.
In the event of an accident, the glass may
shatter. This may result in an opening in the
roof.
In a vehicle rollover, occupants not wearing
their seat belts or not wearing them properly
may be thrown out of the opening. Such an
opening also presents a potential for injury
for occupants wearing their seat belts
properly as entire body parts or portions of
them may protrude from the passenger
compartment.
When leaving the vehicle, always remove the
SmartKey or SmartKey with KEYLESS-GO*
from the starter switch, take it with you, and
lock the vehicle. Do not leave children unat-
tended in the vehicle, or with access to an
unlocked vehicle. Unsupervised use of vehi-
cle equipment can cause an accident
and/or serious personal injury.!
To avoid damaging the seals, do not trans-
port any objects with sharp edges which can
stick out of the tilt/sliding sunroof.Do not open the tilt/sliding sunroof if there is
snow or ice on the roof, as this could result in
malfunctions.
The tilt/sliding sunroof can be opened or closed
manually should an electrical malfunction occur
(
page 617).
i
When the tilt/sliding sunroof is open, reso-
nance noises may result in addition to the usual
wind noises. They are caused by minimal pres-
sure changes in the passenger compartment. To
reduce or eliminate these noises, change the po-
sition of the tilt/sliding sunroof or open a side
window slightly.
