Problems with the rear window defroster Problem
Possible causes/consequences and P Solutions
The rear window
defroster has deactiva-
ted prematurely or can-
not be activated. The battery has not been sufficiently charged. X
Switch off any consumers that are not required, e.g. reading lamps,
interior lighting or the seat heating.
When the battery is sufficiently charged, the rear window defroster
can be activated again.
Switching air-recirculation mode
on/off
General notes You can also temporarily deactivate the flow of
fresh air manually if unpleasant odors are enter-
ing the vehicle from outside. The air already
inside the vehicle will then be recirculated.
If you switch on air-recirculation mode, the win-
dows can fog up more quickly, in particular at
low temperatures. Only use air-recirculation
mode briefly to prevent the windows from fog-
ging up.

Switching the residual heat on or off
General notes Vehicles with rear-compartment climate
control: once the engine is switched off, it is
possible to make use of the residual heat of the
engine to continue heating or ventilating the
rear and front compartment of the vehicle for
approximately 15 minutes. If the "Residual heat"
function is set for only the front or only the rear
compartment, it is possible to continue heating
or ventilating for approximately 30 minutes.
Vehicles without rear-compartment climate
control: once the engine is switched off, it is
possible to make use of the residual heat of the
engine to continue heating or ventilating the
front compartment of the vehicle for approx-
imately 30 minutes.
The heating or ventilation time depends on the
temperature that has been set.140

In such situations, brake if necessary.
DISTRONIC PLUS is then deactivated.
DISTRONIC PLUS with Steering Assist
and Stop&Go Pilot General notes
DISTRONIC PLUS with Steering Assist and
Stop&Go Pilot helps you keep the vehicle in the
center of the lane by means of moderate steer-
ing interventions in a speed range from
0–125 mph (0–200 km/h).
It monitors the area in front of your vehicle by
means of multifunction camera C , at the top of
the windshield.
In a speed range from 0 - 37 mph (0 - 60 km/h),
Stop&Go Pilot focuses on the vehicle in front,
taking into account lane markings, e.g. when
you are following vehicles in a traffic jam.
At speeds of more than 37 mph (60 km/h),
Steering Assist focuses on clear lane markings
(left and right), only focusing on the vehicle in
front if clear lane markings are not present.
Steering Assist and Stop&Go Pilot do not pro-
vide any support if these conditions do not exist.
DISTRONIC PLUS must be active in order for the
function to be available.
Important safety notes
If you fail to adapt your driving style, DISTRONIC
PLUS with Steering Assist and Stop&Go Pilot
can neither reduce the risk of an accident nor
override the laws of physics. It cannot take
account of road, weather and traffic conditions.
DISTRONIC PLUS with Steering Assist and
Stop&Go Pilot is only an aid. You are responsible
for the distance to the vehicle in front, for vehi- cle speed, for braking in good time and for stay-
ing in your lane.
DISTRONIC PLUS with Steering Assist and
Stop&Go Pilot does not detect road and traffic
conditions and d oes not detect all road users. If
y ou are following a vehicle which is driving
towards the edge of the road, your vehicle could
come into contact with the curb or other road
boundaries. Be particularly aware of other road
users, e.g. cyclists, that are directly next to your
vehicle.
Obstacles such as building site huts on the lane
or projecting out into the lane are not detected.
An inappropriate steering intervention, e.g. after
intentionally driving over a lane marking, can be
corrected at any time if you steer slightly in the
opposite direction.
DISTRONIC PLUS with Steering Assist and
Stop&Go Pilot cannot continuously keep your
vehicle in lane. In some cases, steering inter-
vention is not sufficient to bring the vehicle back
to the lane. In such cases, you must steer the
vehicle yourself to ensure that it does not leave
the lane.
The support provided by the system can be
impaired if: R
there is poor visibility, e.g. due to insufficient
illumination of the road, or due to snow, rain,
fog or spray R
there is glare, e.g. from oncoming traffic, the
sun or reflection from other vehicles (e.g. if
the road surface is wet) R
the windshield is dirty, fogged up, damaged or
covered, for instance by a sticker, in the vicin-
ity of the camera R
there are no, several or unclear lane markings
for a lane, e.g. in areas with road construction
w o rk R
the lane markings are worn away, dark or cov-
ered up, e.g. by dirt or snow R
the distance to the vehicle in front is too small
and the lane markings thus cannot be detec-
ted R
the lane markings change quickly, e.g. lanes
branch off, cross one another or merge R
the road is narrow and winding R
there are strong shadows cast on the roadDriving systems 177
Driving and parking Z

make sure that there are no persons, animals or
objects in the area in which you are maneuver-
ing.
You are always responsible for safety, and must
always pay attention to your surroundings when
parking and maneuvering. This applies to the
areas behind, in front of and beside the vehicle.
You could otherwise endanger yourself and oth-
ers.
The 360° camera will not function or will func-
tion in a limited manner: R
if the doors are open R
if the exterior mirrors are folded in R
if the trunk lid is open R
in heavy rain, snow or fog R
at night or in very dark places R
if the cameras are exposed to very bright light R
if the area is lit by fluorescent bulbs or LED
lighting (the display may flicker) R
if the camera lenses fog up, e.g. when driving
into a heated garage in winter, causing a rapid
change in temperature R
if the camera lenses are dirty or covered.
Observe the notes on cleaning
( Y
page 323) R
if the vehicle components in which the cam-
eras are installed are damaged. In this event,
have the camera position and setting checked
at a qualified specialist workshop
Do not use the 360° camera in this case. You
can otherwise injure others or cause damage to
objects or the vehicle.
The guide lines on the multimedia system show
the distances to your vehicle. The distances only
apply to road level.
The cameras in the front and in the rear area are
each protected by a flap. These flaps are opened
when the 360° camera is activated. Observe the
notes on cleaning ( Y
page 323). For technical
reasons, the flaps may remain open briefly after
the 360° camera has been deactivated.
The field of vision and other functions of the
camera system may be restricted due to addi-
tional attachments (e.g. license plate holder,
rear bicycle carrier).
On vehicl es w ith height-adjustable chassis,
dependi
ng on technical conditions, leaving the
standard height can result in: R
inaccuracies in the guide lines R
inaccuracies in the display of generated
images (top view) Activation conditions The image from the 360° camera appears if: R
the multimedia system is switched on R
the 360° Camera function is switched on
If the 360° camera is activated at speeds above
approximately 19 mph (30 km/h), a warning
message appears.
The warning message disappears if: R
the vehicle's speed falls below approximately
19 mph (30 km/h). The 360° camera is then
activated. R
the message is confirmed with the 8 but-
ton.

and any obstacles in good time. When pedes-
trian recognition is active, pedestrians recog-
nized by the system are visually highlighted in
color in the Night View Assist Plus display with
small frame corners.
In addition, an infrared camera is integrated into
radiator trim C . The camera helps detect
pedestrians and animals. Observe the notes on
cleaning the infrared camera ( Y
page 324).
i Infrared light is not visible to the human eye
and therefore does not glare. Night View
Assist Plus can therefore remain switched on
even if there is oncoming traffic.
Important safety notes Night View Assist Plus is only an aid and is not a
substitute for attentive driving. Do not rely on
the Night View Assist Plus display. You are
responsible for the distance to the vehicle in
front, for vehicle speed and for braking in good
time. Drive carefully and always adapt your driv-
ing style to suit the prevailing road and traffic
conditions.
The system may be impaired or may not function
if: R
there is poor visibility, e.g. due to snow, rain,
fog or spray R
the windshield is dirty, fogged up or covered,
for instance by a sticker, in the vicinity of the
camera R
the infrared camera in the radiator trim is
dirty, fogged up or obscured R
on bends, hilltops or downhill gradients R
at high outside temperatures
Night View Assist Plus cannot display objects
directly in front of or beside the vehicle.
It is possible that, in addition to people and ani-
mals, other objects are also marked or highligh-
ted .
Pedestrian and animal recognition
General notes
Pedestrian or animal recognition may be
impaired or inoperative if: R
pedestrians or animals are partially or entirely
obscured by other objects, e.g. parked vehi-
cles R
the silhouette of the pedestrian or of the ani-
mal in the Night View Assist Plus display is incomplete or interrupted, e.g. by powerful
light reflections R
pedestrians or animals do not contrast with
the surroundings R
the camera system no longer recognizes
pedestrians as persons due to special cloth-
ing or other objects R
pedestrians are not in an upright position, e.g.
sitting, squatting or lying R
animals are not recognized by the system,
e.g. because of their size or shape
Pedestrian and animal recognition is deactiva-
ted at temperatures above 90 ‡ (32 †). The
spotlight function and automatic delayed
switch-off are then no longer active.
