Optimum use of the automatic climate
control
The following contains notes and recommenda-
tions on optimum use of the dual-zone or 3-zone
automatic climate control.
RYou can switch on climate control by using the
à and¿ orà andÁ buttons.
The indicator lamps in the Ãand
¿ buttons or the ÃandÁ buttons
light up.
RVehicles with 3-zone climate control: in
automatic mode, you can also use the
ñ button to set a climate mode (FOCUS/
MEDIUM/DIFFUSE). The MEDIUM level is
recommended.
RSet the temperature to 72 ‡ (22 †).
ROnly use the "Windshield defrosting" function
briefly until the windshield is clear again.
ROnly use air-recirculation mode briefly, e.g. if
there are unpleasant outside odors or when in
a tunnel. The windows could otherwise fog up,
since no fresh air is drawn into the vehicle in
air-recirculation mode.
RVehicles with 3-zone climate control: use
the ZONE function to adopt the temperature
settings on the driver's side for the front-
passenger side and the rear compartment as
well. The indicator lamp above the ábut-
ton goes out.
RVehicles with 3-zone climate control: use
the "residual heat" function if you want to heat
or ventilate the vehicle interior when the igni-
tion is switched off. The residual heat function
can only be activated or deactivated with the
ignition switched off.
RIf you change the settings of the climate con-
trol system, the climate status display
appears for approximately three seconds at
the bottom of the screen in the multimedia
system display. You will see the current set-
tings of the various climate control functions.
During automatic engine switch-off, the climate
control system only operates at a reduced capa-
city. If you require the full climate control output,
you can switch off the ECO start/stop function
by pressing the ECO button (
Ypage 137).

with the curb or other road boundaries. Be par-
ticularly aware of other road users, e.g. cyclists,
that are directly next to your vehicle.
Obstacles such as traffic pylons on the lane or
projecting out into the lane are not detected.
An inappropriate steering intervention, e.g. afterintentionally driving over a lane marking, can be
corrected at any time if you steer slightly in theopposite direction.
DISTRONIC PLUS with Steering Pilot cannot
continuously keep your vehicle in lane. In some
cases, the steering intervention 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:
Rthere is poor visibility, e.g. due to insufficient
illumination of the road, or due to snow, rain,
fog or spray
Rthere is glare, e.g. from oncoming traffic, the
sun or reflections (e.g. when the road surface is wet)
Rthe windshield is dirty, fogged up, damaged or
covered, for instance by a sticker, in the vicin-
ity of the camera
Rthere are no, several or unclear lane markings
for a lane, e.g. in areas with road construction
work
Rthe lane markings are worn away, dark or cov-
ered up, e.g. by dirt or snow
Rthe distance to the vehicle in front is too small
and the lane markings thus cannot be detec-
ted
Rthe lane markings change quickly, e.g. lanes
branch off, cross one another or merge
Rthe road is narrow and winding
Rthere are strong shadows cast on the road
The system is switched to passive and no longer
assists you by performing steering interventions if:
Ryou actively change lane
Ryou switch on the turn signal
Rtake your hands off the steering wheel or do
not steer for a prolonged period of time
iAfter you have finished changing lanes,
Steering Pilot is automatically active once
more. Steering Pilot cannot provide assistance:
Ron very sharp corners
Rwhen towing a trailer
Rwhen a loss of tire pressure or a defective tire
has been detected and displayed
Observe the important safety notes on Distance
Pilot DISTRONIC (
Ypage 168).
The steering interventions are carried out with a
limited steering moment. The system requires
the driver to keep his hands on the steering
wheel and to steer himself.
If you do not steer yourself or if you take your
hands off the steering wheel for a prolonged
period of time, the system will first alert you with
a visual warning. A steering wheel symbol
appears in the multifunction display. If you have
still not started to steer and have not taken hold
of the steering wheel after five seconds at the
latest, a warning tone also sounds to remind you
to take control of the vehicle. Steering Pilot is
then switched to passive. Distance Pilot
DISTRONIC remains active.

Rear view camera
General notes
Rear view camera :is an optical parking and
maneuvering aid. It shows the area behind your vehicle with guide lines in the multimedia sys-
tem.
The area behind the vehicle is displayed as a
mirror image, as in the rear view mirror.
iThe text shown in the multimedia system
display depends on the language setting. The
following are examples of rear view camera
displays in the multimedia system.
Important safety notes
The rear view camera is only an aid. It is not a
replacement for your attention to your immedi-
ate surroundings. You are always responsible
for safe maneuvering and parking. When maneu-
vering or parking, make sure that there are no
persons, animals or objects in the area in which you are maneuvering.
Under the following circumstances, the rear
view camera will not function, or will function in
a limited manner:
Rif the trunk lid is open
Rin heavy rain, snow or fog
Rat night or in very dark places
Rif the camera is exposed to very bright light
Rif the area is lit by fluorescent bulbs or LED
lighting (the display may flicker)
Rif there is a sudden change in temperature,
e.g. when driving into a heated garage in win- ter
Rif the camera lens is dirty or obstructed
Observe the notes on cleaning
(
Ypage 323)
Rif the rear of your vehicle is damaged. In this
event, have the camera position and setting
checked at a qualified specialist workshop
The field of vision and other functions of the rear
view camera may be restricted due to additional
accessories on the rear of the vehicle (e.g.
license plate holder, bicycle rack).
For technical reasons, leaving the standard
height can result in inaccuracies in the guide
lines on vehicles with a height-adjustable chas-
sis.
iThe rear view camera is protected from rain-
drops and dust by means of a flap. When the
rear view camera is activated, this flap opens.

360° camera
General notes
The 360° camera is a system consisting of four
cameras.
The system processes images from the follow-
ing cameras:
RRear view camera
RFront camera
RTwo cameras in the exterior rear view mirrors
The cameras capture the immediate surround-
ings of the vehicle. The system supports you,
e.g. when parking or if vision is restricted at an
exit.
You can show pictures from the 360° camera in
full-screen mode or in seven different split-
screen views on the multimedia system display.
A split-screen view also includes a top view of
the vehicle. This view is calculated from the data
supplied by the installed cameras (virtual cam-
era).
The six split-screen views are:
RTop view and picture from the rear view cam-
era (130° viewing angle)
RTop view and image from the front camera
(130° viewing angle without displaying the
maximum steering wheel angle)
RTop view and enlarged rear view
RTop view and enlarged front view
RTop view and rear-view images from the exte- rior mirror cameras (rear wheel view)
RTop view and forward-view images from the
exterior mirror cameras (front wheel view)
When the function is active and you shift the
transmission from Dor Rto N, the dynamic
guidelines are hidden.
When you change between transmission posi-
tions Dand R, you see the previously selected
front or rear view.
Distances measured by Parking Assist
PARKTRONIC will also be optically displayed:
Rin split screen view as red or yellow brackets around the vehicle icon in the top view, or
Rat the bottom right as red or yellow brackets
around the vehicle symbol in full-screen mode
The line thickness and color of the brackets
show how far the vehicle is away from an object:
Ryellow brackets with thin lines: Parking Assist
PARKTRONIC is active
Ryellow brackets with normal lines: an object is present in close range of the vehicle
Rred line: an object is present in the immediate
close range of the vehicle
iThe camera in the rear area is protected
from raindrops and dust by means of a flap.
When the camera is activated, this flap opens.
The flap closes again when:
Ryou have finished the maneuvering process
Ryou switch off the engine
Ryou open the cargo compartment
Observe the notes on cleaning (
Ypage 323).
For technical reasons, the flap may remain
open briefly after the camera has been deac-
tivated.
Important safety notes
The 360°camera is only an aid and may show a
distorted view of obstacles, show them incor-
rectly or not at all. The 360°camera is not a
substitute for attentive driving.
You are always responsible for safe maneuver-
ing and parking. When maneuvering or parking,
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.

Lane Keeping Assist
General notes
:Lane Keeping Assist camera
Lane Keeping Assist monitors the area in front of
your vehicle with camera :, which is mounted
at the top of the windshield. Active Lane Keeping
Assist detects lane markings on the road and
can warn you before you leave your lane unin-
tentionally.
This function is available in the range between
40 mph and 120 mph (60 km/h and 200 km/h).
A warning may be given if a front wheel passes
over a lane marking. It will warn you by means of
intermittent vibration in the steering wheel for
up to 1.5 second s.
Important safety notes
GWARNING
Lane Keeping Assist may not always clearly
recognize lane markings.
In this case, Lane Keeping Assist may:
Rgive an unnecessary warning
Rnot give a warning
There is a risk of an accident.
Always pay particular attention to the traffic
situation and stay in lane, in particular if
warned by Lane Keeping Assist.
GWARNING
The Lane Keeping Assist warning does not
return the vehicle to the original lane. There is
a risk of an accident.
You should always steer, brake or accelerate
yourself, in particular if warned by Lane Keep-
ing Assist.
If you fail to adapt your driving style, Lane Keep-
ing Assist can neither reduce the risk of an acci-
dent nor override the laws of physics. Lane
Keeping Assist cannot take into account the
road, traffic and weather conditions. Lane Keep- ing Assist is merely 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.
The Lane Keeping Assist does not keep the vehi-
cle in the lane.
The system may be impaired or may not function
if:
Rthere is poor visibility, e.g. due to insufficient
illumination of the road, or due to snow, rain,
fog or spray
Rthere is glare, e.g. from oncoming traffic, the
sun or reflection from other vehicles (e.g. if
the road surface is wet)
Rthe windshield is dirty, fogged up, damaged or
covered, for instance by a sticker, in the vicin-
ity of the camera
Rthere are no, several or unclear lane markings
