DISTRONIC PLUS
General notes
DI ST RONIC PLUS regulates the speed and auto-
matically helps you maintain the distance to the
veh icle detected infront. Vehicle s are detected
wit h the aid of the radar sensor system.
DI ST RONIC PLUS brakes automatically so that
the set speed is not excee ded.Change into a lower gear in good time on long
and steep
downhillgradients. This isespecially
important ifthe vehicle is laden. By doing so, you
will make use of the braking effect of the engine.
This relieves the load on the brake system and
prevents the brakes from overheating and wear-
ing too quickly.
If DI ST RONIC PLUS detects that there isa risk of
a collision, you will bewarned visually and
acoustically. DI STRONIC PLUS cannot prevent a
collision without your intervention. An intermit-
tent warning tone will then sound and the dis-
tance warning lamp willlight up in the instru-
ment cluster. Brake immediately inorder to
increase the distance to the vehicle in front or
take evasive action provided it issafe to doso.
DISTRONIC PLUS operates inrange between
0 mph (0 km/ h)and 120 mph (200km/ h).
Do not use DISTRONIC PLUS while driving on
roads with steep gradients.
As DISTRONIC PLUS transmits radar waves, it
can resemble the radar de tectors o
f the respon-
sible authorities. You can refer to the relevant
chapter in the Operator's Manual if questions
are asked about this.

MAGIC BODY CONTROL
General notes
MAGIC BODY CONTROL consists of Active Body
Control (ABC), ROAD SURFACE SCAN as well as
automatic vehicle stabilization in the event of a
crosswind.
Your vehicle automatically adjusts its ride height
to improve driving safety and reduce fuel con-
sumption. The suspension mode is adjusted
according to your selection (sports or comfort),
the road surface conditions and the vehicle load. A multifunction camera detects bumps in the
road surface before the vehicle drives over
them. This reduces chassis movements.
Important safety notes
GWARNING
When the vehicle is being lowered, people
could become trapped if their limbs are
between the vehicle body and the wheels or
underneath the vehicle. There is a risk of
injury.
Make sure no one is underneath the vehicle or
in the immediate vicinity of the wheel arches
when the vehicle is being lowered.
!The vehicle is lowered when the engine is
switched off. When parking, position your
vehicle so that it does not make contact with
the curb as the vehicle is lowered. Your vehi-
cle could otherwise be damaged.
Crosswind Assist
The crosswind stabilization operates by chang-
ing wheel loads through adjusting the ABC
spring struts. It reduces impairments in handling
when driving in a straight line and assists during
countersteering. Crosswind Assist is active in the speed range
between 50 mph (80 km/h)
and
130 mph (210 km/h) when driving straight
ahead or cornering gently.

Active Parking Assist
General notes
Active Parking Assist is an electronic parking aid
with ultrasound. It measures the road on both
sides of the vehicle. A parking symbol indicates a suitable parking space. Active steering inter-
vention and brake application can assist you
during parking and when exiting a parking
space. You may also use PARKTRONIC
(
Ypage 214).
Important safety notes
Active Parking Assist is merely an aid. It is not a
replacement for your attention to your immedi-
ate surroundings. You are always responsible
for safe maneuvering, parking and exiting a
parking space. Make sure that no persons, ani-
mals or objects are in the maneuvering range.
When PARKTRONIC is switched off, Active Park-
ing Assist is also unavailable.
GWARNING
While parking or pulling out of a parking
space, the vehicle swings out and can drive
onto areas of the oncoming lane. This could
result in a collision with another road user.
There is a risk of an accident.
Pay attention to other road users. Stop the
vehicle if necessary or cancel the Active Park- ing Assist parking procedure.
!If unavoidable, you should drive over obsta-
cles such as curbs slowly and not at a sharp
angle. Otherwise, you may damage the
wheels or tires.
Active Parking Assist may possibly indicate
parking spaces which are not suitable for park-
ing, for example:
Rwhere parking or stopping is prohibited
Rin front of driveways or entrances and exits
Ron unsuitable surfaces
Parking tips:
ROn narrow roads, drive as close to the parking
space as possible.
RParking spaces that are littered or overgrown
might be identified or measured incorrectly.
RParking spaces that are partially occupied by
trailer drawbars might not be identified as
such or be measured incorrectly.

iThe text shown in the multimedia system
depends on the language setting. The follow- ing 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 whichyou 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 the camera lens fogs up, e.g. when driving

Warning display
:Warning display
Active Blind Spot Assist is not operational at
speeds below approximately 20 mph (30 km/h).
Vehicles in the monitoring range are then not
indicated.
If a vehicle is detected within the blind spot
monitoring range at speeds above 20 mph
(30 km/h), warning lamp :on the correspond-
ing side lights up red. This warning is always
emitted when a vehicle enters the blind spot
monitoring range from behind or from the side.
When you overtake a vehicle, the warning only
occurs if the difference in speed is less than
7 mph (12 km/h).
If you select the reverse gear, Active Blind Spot
Assist is not operational.
The brightness of the warning lamps is auto-
matically adapted to the brightness of the sur-
roundings.
When Active Blind Spot Assist is activated, gray
radar waves propagating backwards appear
next to the vehicle in the assistance display in
the multifunction display. Above a speed of
20 mph (30 km/h), the color of the radar waves
in the assistance display changes to green ;.
Active Blind Spot Assist is then ready for use.
Visual and acoustic collision warning
If you switch on the turn signals to change lanes and a vehicle is detected in the side monitoring
range, you receive a visual and acoustic collision warning. You will then hear a double warning tone and red warning lamp
:flashes. If the turn
signal remains on, detected vehicles are indica-
ted by the flashing of red warning lamp :.
There are no further warning tones.
Course-correcting brake application
If Active Blind Spot Assist detects a risk of a lat-
eral collision in the monitoring range, a course-
correcting brake application is carried out. This
is meant to assist you in avoiding a collision.
GWARNING
A course-correcting brake application cannot always prevent a collision. There is a risk of an
accident.
Always steer, brake or accelerate yourself,
especially if Active Blind Spot Assist warns
you or makes a course-correcting brake appli-
cation. Always maintain a safe distance at the
sides.
If a course-correcting brake application occurs,
red warning lamp :flashes in the exterior mir-
ror and a dual warning tone sounds. In addition,
display ;underlining the danger of a side col-
lision appears in the multifunction display.
In very rare cases, the system may make an
inappropriate brake application. A course-cor-
recting brake application may be interrupted at
any time by countersteering slightly or acceler-
ating.
The course-correcting brake application is avail-
able in the speed range between 20 mph
(30 km/h) and 120 mph (200 km/h).

Active Lane Keeping Assist
General notes
Active Lane Keeping Assist monitors the area in
front of your vehicle by means of multifunction
camera :at the top of the windshield. Various
different areas to the front, rear and side of your
vehicle are also monitored with the aid of the
radar sensor system. Active Lane Keeping
Assist detects lane markings on the road and
can warn you before you leave your lane unin- tentionally. If you do not react to the warning, a
lane-correcting application of the brakes can
bring the vehicle back into the original lane.
This function is available in a speed range
between 40 mph and 120 mph (60 km/h and
200 km/h).
Important safety notes
If you fail to adapt your driving style, Active Lane
Keeping Assist can neither reduce the risk of
accident nor override the laws of physics. Active
Lane Keeping Assist cannot take account of
road and weather conditions. It may not recog-
nize traffic situations. Active Lane Keeping
Assist is only an aid. You are responsible for the
distance to the vehicle in front, for vehicle
speed, for braking in good time and for staying in
your lane.
Active Lane Keeping Assist cannot continuously
keep your vehicle in its lane.
GWARNING
Active Lane Keeping Assist cannot always
clearly detect lane markings.
In such cases, Active Lane Keeping Assist
can:
Rgive an unnecessary warning and then
make a course-correcting brake application
to the vehicle
Rnot give a warning or intervene
There is a risk of an accident.
Always pay particular attention to the traffic
situation and keep within the lane, especially
if Active Lane Keeping Assist alerts you. Ter-
minate the intervention in a non-critical driv-
ing situation.
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 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
