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.

Tips for driving with DISTRONIC PLUS General notes
The following contains descriptions of certain
road and traffic conditions in which you must
be particularly attentive. In such situations,
brake if necessary .DISTRONIC PLUS is then
deactivated.
Cornering, going into and comingo ut of a
bend The ability of DISTRONIC PLUS to detect vehi-
cles when cornering is limited. Yourv
ehicle
may brake unexpectedly or late.
Vehicles travelling on adifferent line DISTRONIC PLUS may not detec
tvehicles
travelling on adifferent line. The distance to
the vehicle in fron twill be too short. Driving systems
179Driving and parking Z
Other vehicles changing lane
DISTRONIC PLUS has not detected the vehi-
cle cutting in yet. The distanc
etothis vehicle
will be too short.
Narrow vehicles DISTRONIC PLUS has not yet detected the
vehicle in fron
tonthe edge of the carriage-
way,b ecause of its narrow width. The dis-
tance to the vehicle in front will be too short.
Obstructions and stationary vehicles DISTRONIC PLUS does not brake for obsta-
cles or stationary vehicles. If, for example, the detected vehicle turns
acorner and reveals
an obstacle or stationary vehicle, DISTRONIC
PLUS will not brake for these.
Crossing vehicles DISTRONIC PLUS may detect vehicles that
are crossing your lane by mistake. Activating
DISTRONIC PLUS at traffic lights with cross-
ing traffic, for example, could cause your vehi-
cle to pull away unintentionally.
SPEEDTRONIC
Important safety notes SPEEDTRONIC brakes automatically so that
you do not exceed the set speed. On long and
steep downhill gradients, especiallyift
he
vehicle is laden or towing atrailer, you must
shift to alower gear in good time or select
shift range 1,2or 3on vehicles with auto-
matic transmission. By doing so, you will
make use of the braking effect of the engine,
which relieves the load on the brake system
and prevents the brakes from overheating
and wearing too quickly. If you need addi-
tional braking, depress the brake pedal
repeatedly rather than continuously. G
WARNING
Never depress the brake pedal continuously
while the vehicle is in motion, e.g. never cause
the brakes to rub by applying constant slight
pedal pressure. This causes the brake system
to overheat, increases the braking distance
and can lead to the brakes failing completely. 180

Monitoring range
Active Blind Spot Assist monitors the area up
to three metres behind yourv
ehicle and
directly nexttoy our vehicle, as shown in the
diagram. For this purpose, Active Blind Spot
Assist uses radar sensors in the rear bumper. Example: Coupé
G
WARNING
Active Blind Spot Assist monitors certain
areas in the immediate vicinit yofyour vehicle.
Vehicles that approach and drive past at high
speeds are not detected. No visual nor audi-
ble warnings are emitted and the system does
not brake the vehicle to correc tyour course.
If the lanes are very wide, it may not be pos-
sible to monitor the complete width of the
neighbouring lane. For this reason, vehicles in
the next lane may not be detected, especially
if they are driving in astaggered formation.
This may be the case if vehicles are driving at
the edge of their lane that is furthest away
from your vehicle.
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.
If the lanes are narrow, vehicles driving in the
lane beyond the lane next to your vehicle may
be indicated, especially if the vehicles are not driving in the middle of their lane. This may
be the case if the vehicles are driving on the
inner side of their lane.
Due to the nature of the system:
R
warnings may be issued in error when driv-
ing close to crash barriers or similar solid
lane borders.
R warnings may be interrupted when driving
alongside particularly long vehicles, for
example lorries, for aprolonged time.
Two Active Blind Spot Assist radar sensors
are integrated into the front and rear bumpers
respectively. An additional radar sensor is
located behind the cover in the radiator grille.
Make sure that the bumpers are free of dirt,
ice or slush around the sensors. The rear sen-
sors must not be covered, for example by
cycle racks or overhanging loads. Following a
severe impact or in the event of damage to
the bumpers, have the function of the radar
sensors checked at aqualified specialist
workshop, e.g. aMercedes-Benz Service
Centre. Active Blind Spot Assist may other-
wise fail to work correctly.
Indicator and warning display :
Yellow indicator lamp/red warning lamp
When Active Blind Spot Assist is activated,
indicator lamp :in the exterior mirrors lights
up in yellow at speeds of up to 30 km/h. At
speeds above 30 km/h, the indicator lamp
goes out and Active Blind Spot Assist is
operational.
If av ehicle is detected within the monitoring
range of Blind Spot Assist at speeds above 200
Driving systemsDriving and parking
30 km/h, warning lamp
:on the corre-
sponding sid elights up red. Thi swarning is
always emitted whe navehicle enters the
blind spot monitoring range from behind or
from the side .When you overtake avehicle,
the warning only occurs if the difference in
speed is less than 12 km/h.
The yellow indicator lamp goes out if reverse
gear is engaged. Active Blind Spot Assist is
then no longer active.
The brightness of the indicator/warning
lamps is adjusted automatically according to
the ambient light. G
WARNING
Active Blind Spot Assist is not active at speeds
below 30 km/h. The indicator lamps in the
exterior mirrors are yellow.V ehicles in the
monitoring range are then not indicated.
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.
Visua land acoustic collisio nwarning
If you switch on the appropriate turn signals
to change lanes, and avehicle is detected in
the side monitoring range of Active Blind Spot
Assist ,you will receive avisual and acoustic
collision warning. You will then hear adouble
warning tone, and red warning lamp :
flashes. If the turn signal remains on, detec-
ted vehicles are indicated by the flashing of
red warning lamp :.There are no further
warning tones.
Course-correcting brak eapplication
If Active Blind Spot Assist detects arisk of a
lateral collision in the monitoring range, a
course-correcting brake application is carried
out. This is designed to help you avoid acol-
lision.
The course-correcting brake application is
available in the range between 30 km/ha nd
200 km/h.
If ac ourse-correcting brake application
occurs, red warning lamp :flashe sinthe exterio

WARNING
Activ eBlindS pot Assist is only an aid
designed to assist driving. It is not asubstitute
for attentive driving. Automatic braking by the
system may not always be sufficien ttoavoid
ac ollision. In such cases, you need to steer,
brake or accelerate yourself.
In very rare cases, the system may detect a
risk of collision where there is none and brake
in error near crash barriers or similar road
boundaries. Active Blind Spot Assist cannot
detect all traffic situations and road users.
Ensure at all times that there is sufficient lat-
eral distance between you and other road
users or obstacles. You can, for example,
countersteer gently or depress the accelera-
tor pedal at any time to cancel inappropriate
braking action.
You are responsible for the vehicle's speed,
correc tsteerin gand for braking in good time.
Alway sadapt your drivin gstyle to suit the
prevailing road and weather conditions.
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.
Either avery slight course-correcting brake
application, or none at all, may occur if:
R there are vehicles or obstacles, e.g. crash
barriers, on both sides of your vehicle.
R av ehicle approaches too closely on the
side.
R you have adopted asporty driving style with
high cornering speeds.
R you brake or accelerate decisively. Driving systems
