G
Risk of accident
The brake pedal is retracted when Distronic
brakes. Do not restrict the movement of the
pedal in any way.
R Do not put any objects in the footwell.
R Ensure that floor mats and carpets are fixed
securely.
R Do not place your foot under the brake
pedal as it could become trapped.
You could otherwise cause an accident and
injure yourself and others. G
Risk of accident
Do not change down for additional engine
braking on a slippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid. G
Risk of accident
Distronic is only an aid designed to assist
driving. The driver remains fully responsible
for the vehicle's distance from other vehicles,
the vehicle's speed and for braking in good
time.
Distronic does not react to:
R pedestrians
R stationary obstacles on the road, e.g. sta-
tionary or parked vehicles
R oncoming and crossing traffic
Distronic may not detect narrow vehicles driv-
ing in front, e.g. motorcycles, or vehicles driv-
ing on a different line. Therefore, always pay
attention to traffic conditions even when Dis-
tronic is activated. Otherwise, you may fail to
recognise dangers in time, could cause an
accident and injure yourself and others.
If a slower-moving vehicle is detected in front,
Distronic causes your vehicle to brake and
maintain the preset distance to the vehicle in
front that you have set. G
Risk of accident
Distronic cannot take account of road and
traffic conditions. Deactivate, or do not acti-
vate, Distronic if it does not detect the vehicle
in front, or if it no longer detects it. This is
especially the case:
R before corners
R in filter lanes
R when changing to a lane with faster moving
traffic
R in complex driving situations or where the
lanes are diverted, e.g. at roadworks on a
motorway
Otherwise, Distronic maintains the current
speed or accelerates to the set speed.
Distronic cannot take account of weather
conditions. Deactivate, or do not activate,
Distronic:
R if the roads are slippery, snow-covered or
icy. The wheels could lose their grip when
braking or accelerating. The vehicle could
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 is activated. Otherwise,
you may fail to recognise dangers in time,
could cause an accident and injure yourself
and others.
If there is no vehicle in front, Distronic oper-
ates in the same way as cruise control. Dis-
tronic functions in the 30 km/h to
200 km/h range. G
Risk of accident
Distronic brakes your vehicle at a maximum
of 2 m/s 2
, depending on its speed. This cor-
responds to approximately 20% of your vehi-
cle's maximum braking power. You must also
apply the brakes yourself if this braking power
is not sufficient. 230

G
Risk of accident
Distronic Plus cannot take account of road
and traffic conditions. If Distronic does not
recognise or no longer recognises the vehicle
in front, do not activate Distronic or, if it is
already active, deactivate it. This is especially
the case:
R before corners
R in filter lanes
R when changing to a lane with faster moving
traffic
R in complex driving situations or where the
lanes are diverted, e.g. at roadworks on a
motorway
Otherwise, Distronic Plus maintains the cur-
rent speed 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 roads are slippery, snow-covered or
icy. The wheels could lose their grip when
braking or accelerating. The vehicle could
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. Other-
wise, you may fail to recognise dangers in
time, could cause an accident and injure your-
self and others.
! You must deactivate the radar sensor sys-
tem in certain countries and near radio
telescope facilities. Further information
can be found in the index under "Radar
sensor system".
Vehicles with COMAND and navigation sys-
tem*: you must deactivate the radar sensor
system near radio telescope facilities
(Y page 411). If you want Distronic Plus to assist you, the
radar sensor system must be activated and
operational.
If no car is driving in front of you, Distronic
Plus works like cruise control in the speed
range between 30 km/h and 200 km/h. If a
vehicle is driving in front of you, Distronic Plus
works in the speed range between 0 km/h
and 200 km/h.
Do not use Distronic Plus while driving on
roads with steep gradients.
G
Risk of accident
Distronic Plus brakes your vehicle at a maxi-
mum of 4m/s2
depending on its speed. This
corresponds to approximately 40% of your
vehicle's maximum brake force. You must
also apply the brakes yourself if this braking
power is not sufficient.
If Distronic Plus detects a risk of collision with
a vehicle in front, an intermittent warning tone
sounds. In addition, the ·distance warn-
ing lamp in the instrument cluster lights up.
Brake to avoid a collision.
Cruise control lever With the cruise control lever you can operate
Distronic Plus and variable Speedtronic.
The LIM indicator lamp on the cruise control
lever indicates which system you have selec-
ted:
R
LIM indicator lamp off:
Distronic Plus is selected.

Information and warning display
:
Yellow indicator lamp/red warning lamp
When you turn the key to position 2in the
ignition lock, warning lamps :in the exterior
mirrors light up red.
If Blind Spot Assist is switched on and the
engine is running, indicator lamps :in the
exterior mirrors light up yellow up to a speed
of 30 km/h. At speeds above 30 km/h, the
indicator lamp goes out and Blind Spot Assist
is operational.
If a vehicle is detected within the monitoring
range of Blind Spot Assist at speeds above
30 km/h, warning lamp :on the corre-
sponding side lights up red.
The yellow indicator lamp goes out three sec-
onds after reverse gear is engaged. In this
event, Blind-Spot Assist is no longer active.
The brightness of the indicator/warning
lamps is adjusted automatically according to
the ambient light. G
Risk of accident
Blind Spot Assist is not active at speeds below
30 km/h, and the indicator lamps in the exte-
rior mirrors are yellow. Vehicles in the moni-
toring range are then not indicated.
Always pay attention to traffic conditions and
your surroundings. Otherwise, you may fail to
recognise dangers in time, could cause an
accident and injure yourself and others. Collision warning If a vehicle is detected in the monitoring range
of Blind Spot Assist and you switch on the turn
signal, a double warning tone sounds. Red
warning lamp
:flashes. If the turn signal
remains on, detected vehicles are indicated
by the flashing of red warning lamp :. There
are no further warning tones.
Activating X
Make sure that the radar sensor system
(Y page 226) and Blind Spot Assist
(Y page 224) are activated in the on-board
computer.
X Turn the key to position 2in the ignition
lock.
Red warning lamps :in the exterior mir-
rors are lit.
X Start the engine.
Warning lamps :in the exterior mirrors
now light up yellow. Air conditioning
General notes
The automatic air conditioning controls the
temperature and the humidity of the vehicle
interior and filters out undesirable substan-
ces from the air.
The automatic air conditioning is only opera-
tional when the engine is running. 31
Optimum
operation is only achieved when you drive
with the side windows and sliding/tilting sun-
roof closed.
i Ventilate the vehicle for a brief period
during warm weather, e.g. using the con-
venience opening feature (Y page 201).
This will speed up the cooling process and
the desired vehicle interior temperature
will be reached more quickly.
31 The "residual heat" function can only be switched on/off if the ignition is switched off. 262

i
The integrated filter can filter out most
particles of dust and completely filters out
pollen. A clogged filter reduces the amount
of air supplied to the vehicle interior. For
this reason, you should always observe the
interval for replacing the filter, which is
specified in the Service Booklet. As it
depends on environmental conditions, e.g.
heavy air pollution, the interval may be
shorter than stated in the Service Booklet. G
Risk of accident
Observe the settings recommended on the
following pages. Otherwise, the windows
could mist up. This may obstruct your view of
the traffic situation and, as a result, you may
cause an accident. Overview of air-conditioning system functions
