WARNING
PRE-SAFE ®
Brake does not react:
R to people or animals
R to oncoming vehicles
R to crossin gtraffic
R when cornering
As aresult, PRE-SAFE ®
Brake may neither
give warnings nor intervene in all critical sit-
uations. There is arisk of an accident.
Always pay careful attention to the traffic sit-
uation and be ready to brake.
In order to maintain the appropriate distance
to the vehicle in front and thus prevent acol-
lision, you must apply the brakes yourself.
X To activate/deactivate: activate or deac-
tivate PRE-SAFE ®
Brake in the on-board
computer (Y page 219).
When PRE-SAFE ®
Brake is activated, the
Ä symbol appears in multifunction dis-
play, as long as the HOLD function is deac-
tivated (Y page 179). On vehicles with the
Active Parking Assist driving system, the
Ä symbol is displayed when position P
is engaged or you are driving faster than
35 km/h.
For PRE-SAFE ®
Brake to assist you when driv-
ing, the radar sensor system must be
switched on (Y page 225) and be opera-
tional. The radar sensor system is switched off auto-
matically in the vicinit
yofradio telescope
facilities in the following vehicles:
R vehicles with COMAND Online and naviga-
tion
R vehicles with Audio 20 and Becker ®
MAP
PILOT
Becker ®
MAP PILOT must be connected;
see the separate operating instructions.
The radar sensor system must be switched off
using the on-board computer in the vicinit yof
radio telescope facilities in the following vehi-
cles:
R vehicles without COMAND Online and nav-
igation
R vehicles without Audio 20 and Becker ®

R vehicles for Australia
For information on switching off the radar
sensor system using the on-board computer,
see (Y page 225).
Following damage to the front end of the vehi-
cle, have the configuration and operation of
the radar sensors checked at aqualified spe-
cialist workshop. This also applies to colli-
sions at slow speeds where there is no visible
damage to the front of the vehicle. Anti-theft systems

WARNING
DISTRONIC PLUS cannot take account of road
and traffic conditions. If DISTRONIC does not
recognise or no longer recognise sthe vehicle
in front, do not activate DISTRONIC or, if it is
already active, deactivate it. This is especially
the case:
R before corners
R on filter lanes
R when changing to alane with faster moving
traffic
R in comple xdriving situations or where lanes
are diverted ,e.g. at roadworks on amotor-
way
DISTRONIC PLUS otherwise maintains the
current spee dset by you or accelerates up to
the set speed.
DISTRONIC PLUS cannot take account of
weather conditions. Deactivate, or do not
activate, DISTRONIC PLUS:
R if the road sare slippery ,snow-covered or
icy. The wheels could lose their grip when
braking or accelerating. The vehicl ecould
start to skid.
R if the sensors are dirty or there is poor vis-
ibility ,e.g. due to snow, rain or fog. Dis-
tance control may be impaired.
Always pay attention to traffic conditions
even when DISTRONIC PLUS is activated.
Otherwise, you may fail to recognise dangers
in time, caus eanaccident and injure yourself
and others. G
WARNING
DISTRONIC PLUS brakes yourv ehicle up to a
maximum of 4m/s2
depending on its speed.
This corresponds to approximately 40% of
your vehicle's maximum braking power. You
must also apply the brakes yourself if this
braking power is not sufficient.
If DISTRONIC PLUS detect sarisk of collision
with avehicle in front, an intermittent warning
tones ounds. In addition, the ·distance
warning lamp in the instrument cluster lights
up. Brak etoavoidacollision. General notes DISTRONIC PLUS regulates the speed and
automatically helps you maintain the dis-
tanc
etot he vehicle detected in front. DIS-
TRONIC PLUS brakes automatically so that
the set speed is not exceeded.
On long and steep downhill gradients, you
must select shift range 1,2or 3in good time.
By doing so, you will make use of the braking
effec tofthe engine. This relieves the load on
the brake system and prevents the brakes
from overheating and wearing too quickly.
If DISTRONIC PLUS detectsas lower-moving
vehicle in front,y our vehicle is braked in order
to maintain the preset distance to the vehicle
in front.
The radar sensor system is switched off auto-
matically in the vicinity of radio telescope
facilities (Y page 368).
If you want DISTRONIC PLUS to assist you,
the radar sensor system must be activated
(Y page 225) and operational.
If there is no vehicle in front,D ISTRONIC
PLUS operates in the same way as cruise
control in the speed range between
30 km/h and 200 km/h. If avehicle is driving
in fron tofyou, DISTRONIC operates in the
speed range between 0km/h and
200 km/h.
Do not use DISTRONIC PLUS on road swith
steep gradients. Driving systems

PARKTRONIC
Important safety notes G
WARNING
PARKTRONIC is only an aid and may not
detect all obstacles. It is not asubstitute for
attentive driving.
You are always responsible for safety and
must continue to pay attention to your imme-
diate surroundings when parking and
manoeuvring. You could otherwise endanger
yourself and others. G
WARNING
Make sure that no persons or animals are in
the manoeuvring range. Otherwise, they
could be injured.
PARKTRONIC is an electronic parking aid with
ultrasonic sensors. It indicates visuallya nd
audibly the distance between your vehicle
and an object.
PARKTRONIC is activated automatically if
you:
R switch on the ignition
R shift the transmission to position D,Ror N
R release the parking brake
PARKTRONIC is deactivated at speeds above
18 km/h. It is reactivated at lower speeds.
PARKTRONIC monitorst he area around your
vehicle using six sensors in the front bumper
and four sensors in the rear bumper.
Range of the sensors General notes
!
When parking, pay particular attention to
objectsa bove or below the sensors, such
as flower pots or trailer drawbars. PARK-
TRONIC does not detect such objectsw hen
they are in the immediate vicinity of the
vehicle. You could damage the vehicle or
the objects.
The sensors may not detect snow and
objectsw hich absorb ultrasonic sources. Ultrasonic sources, such as an automatic
car wash,
alorry's compressed-air brakes
or ap neumatic drill, could cause PARK-
TRONIC to malfunction.
PARKTRONIC may not function correctly on
uneven terrain. :
Example: sensors in the front bumper,
left-han dside
The sensors must be free of dirt, ice and
slush. Otherwise, they may not function cor-
rectly. Cleant he sensors regularly,t aking
care not to scratchord amage them

Important safety notes G
WARNING
Active Parking Assist is merely an aid and may
sometimes recommendp arking spaces that
are not suitable for parking. For example,
these might be spaces where parking is pro-
hibited, driveways, unsuitable surfaces, etc.
Active Parking Assist measures the parking
space as you drive past it. Any later changes
to the parking space are not taken into
account. For instance, this may be the case
when the vehicle parked in front of or behind
the space changes its position or when an
obstacle is moved into the parking space.
Active Parking Assist does not relieve you of
the responsibility of paying attention. If you
rely solely on Active Parking Assist, you could cause an accident and injure yourself and oth-
ers.
You are always responsible for safety and
must continue to pay attention to your imme-
diate surroundings when parking and
manoeuvring.
G
WARNING
Objectsl ocated above the height range of
Active Parking Assist will not be detected
when the parking space is measured. These
are not taken into account when the parking
procedure is calculated, e. g. overhanging
loads, tail sections or loading ramps of goods
vehicles. In some circumstances, Active Park-
ing Assist may therefore guide you into the
parking space too early. This may lead to a
collision. For this reason, you should avoid
using Active Parking Assist in such situations. Driving systems

Blind Spot Assist Important safety notes
G
WARNING
Blind Spot Assist is only an aid designed to
assist driving. It may fail to detect some vehi-
cles and is no substitute for attentive driving.
Blind Spot Assist cannot detect road and traf-
fic conditions. It may fail to detect narrow
vehicles, such as motorcycles or bicycles, or
only detect them too late.
Monitoring may be affected by dirty sensors,
strongs pray or poor visibility caused by snow,
rain or mist, for example. In this case, vehicles
are detected late or not at all. Always pay attention to traffic conditions and
your surroundings. Otherwise, you may fail to
recognise dangers in time, cause an accident
and injure yourself and others.
General notes
Blind Spot Assist uses aradar sensor system
to monitor the areas on both sides of your
vehicle. It supports you from speeds of
30 km/h. Awarning displayint he exterior
mirrors draws your attention to vehicles
detected in the monitored area. If you then
switch on the corresponding turn signal to
change lane, you will also receive an optical
and audible collision warning. For monitoring,
Active Blind Spot Assist uses sensors in the
rear bumper.
For Blind Spot Assist to assist you when driv-
ing, the radar sensor system must be activa-
ted (Y page 225) and operational.
The radar sensor system is automatically
deactivated near radio telescope facilities
(Y page 368). Driving systems
