At a speed of up to approximately 44 mph
(70 km/h), PRE-SAFE ®
Brake can also detect:
R stationary objects in the path of your vehi-
cle, e.g. stopped or parked vehicles
R pedestrians in the path of your vehicle G
WARNING
PRE-SAFE ®
Brake does not react:
R to small people, e.g. children
R to animals
R to oncoming vehicles
R to crossing traffic
R when cornering
As a result, PRE-SAFE ®
Brake may neither
give warnings nor intervene in all critical sit-
uations. There is a risk of an accident.
Always pay careful attention to the traffic sit- uation and be ready to brake.
In the event of snowfall or heavy rain, the rec-
ognition can be impaired.
Recognition by the radar sensor system is
also impaired in the event of:
R there is dirt on the sensors or anything else
covering the sensors
R there is interference by other radar sources
R there are strong radar reflections, for
example in parking garages
R a narrow vehicle traveling in front, e.g. a
motorbike
R a vehicle traveling in front on a different line
relative to the center of your vehicle
Recognition by the camera system is also
impaired in the event of:
R dirt on the camera or if the camera is cov-
ered
R there is glare on the camera system, e.g.
from the sun being low in the sky R
darkness
R if:
- pedestrians move quickly, e.g. into the
path of the vehicle
- the camera system no longer recognizes
a pedestrian as a person due to special
clothing or other objects
- a pedestrian is concealed by other
objects
- the typical outline of a person is not dis-
tinguishable from the background
Following damage to the front end of the vehi- cle, have the configuration and operation of
the radar sensors checked at a qualified spe-
cialist workshop. This also applies to colli-
sions at low speeds where there is no visible
damage to the front of the vehicle.
Following damage to the windshield, have the
configuration and operation of the camera
system checked at a qualified specialist work- shop.

stationary and you do not need to depress the
brake.
After a time, the electric parking brake
secures the vehicle and relieves the service
brake.
Depending on the specified minimum dis-
tance, your vehicle will come to a standstill at
a sufficient distance behind the vehicle in
front. The specified minimum distance is set
using the control on the cruise control lever. The electric parking brake automatically
secures the vehicle if DISTRONIC PLUS is
activated and:
R the seat belt is unfastened and the driver's
door is open.
R the engine is switched off, unless it is auto-
matically switched off by the ECO start/

Detected parking space on the left
0044 Parking symbol
0087 Detected parking space on the right
Active Parking Assist is switched on automat-
ically when driving forwards. The system is
operational at speeds of up to approximately 22 mph (35 km/h). While in operation, the
system independently locates and measures
parking spaces on both sides of the vehicle.
Active Parking Assist will only detect parking spaces:
R parallel or at right angles to the direction of
travel
R that are parallel to the direction of travel
and at least 59 in (1.5 m) wide
R that are parallel to the direction of travel
and at least 39.5 in (1.0 m) longer than your
vehicle
R that are at right angles to the direction of
travel and at least 39.5 in (1.0 m) wider
than your vehicle
i Note that Active Parking Assist cannot
measure the length of a parking space if it
is at right angles to the direction of travel.
You will need to judge whether your vehicle
will fit in the parking space.
When driving at speeds below 19 mph
(30 km/h), you will see the parking symbol as a status indicator in the instrument cluster.
When a parking space has been detected, anarrow towards the right or the left also
appears. By default, Active Parking Assist
only displays parking spaces on the front-
passenger side. Parking spaces on the driv- er's side are displayed as soon as the turn
signal on the driver's side is activated. When
parking on the driver's side, this must remain
switched on until you acknowledge the use of
Active Parking Assist by pressing the 0076
button on the multifunction steering wheel.
The system automatically determines
whether the parking space is parallel or at
right angles to the direction of travel.
A parking space is displayed while you are
driving past it, and until you are approx-
imately 50 ft (15 m) away from it.

Important safety notes
G
WARNING
If you manipulate or bridge a faulty fuse or if
you replace it with a fuse with a higher amper- age, the electric cables could be overloaded.
This could result in a fire. There is a risk of an
accident and injury.
Always replace faulty fuses with the specified
new fuses having the correct amperage.
Blown fuses must be replaced with fuses of
the same rating, which you can recognize by
the color and value. The fuse ratings are listed in the fuse allocation chart.
If a newly inserted fuse also blows, have the
cause traced and rectified at a qualified spe-
cialist workshop, e.g. an authorized
Mercedes-Benz Center.
! Only use fuses that have been approved
for Mercedes-Benz vehicles and which
have the correct fuse rating for the system
concerned. Otherwise, components or sys-
tems could be damaged.
The fuses in your vehicle serve to close down faulty circuits. If a fuse blows, all the compo- nents on the circuit and their functions stop
operating. Before changing a fuse
X Secure the vehicle against rolling away
(Y page 174).
X Switch off all electrical consumers.
X Make sure that the ignition is switched off
(Y page 157).
or
X When using the SmartKey, turn the Smart-
Key to position 0in the ignition lock and
remove it (Y page 157).
All indicator lamps in the instrument cluster
must be off. 354
