2010 MERCEDES-BENZ E-CLASS CABRIOLET lane assist

If thes
econditions ar efulfilled ,your vehicle
will accelerate. Acceleration will be interrup-
ted if changin glanes takes too long or the
distanc ebetween your vehicle and the vehi-
cle in fron tbecomes too small. G
Risk of accident
DI ST RONIC PLUS and Active Blind Spot Assist
are only an aid designed to assist driving.
The ydon ot relieve you of the responsibility
of payin gattention. The driver remains fully
responsible for the vehicle's distance from
other vehicles, the vehicle's speed and for
braking in good time. Always pay attention to
traffic conditions and your surroundings. Oth-
erwise, you may fail to recognise dangers in
time, cause an accident and injure yourself
and others.
Vehicles with COMAND APS/Audio 50
APS
i The following functions are not available
in all countries.
DISTRONIC PLUS uses additional information
from your navigation system so that it can
react appropriately to certain traffic situa-
tions. This is the case when, following another
vehicle with the help of DISTRONIC PLUS,
you:
R approach or drive through aroundabout
R approach or tur nataTjunction
R turn off at amotorway exit
Even if the vehicle in front leaves the detec-
tion range, DI STRONIC PLUS temporarily
maintains the current driving speed and does
not accelerate. This is base donthe current
ma pd ata in the navigation system. Roundabout (example)
The current spee
dismaintained:
R approximately 10 seconds before reaching
the roundabout/T junction and approx-
imately 1.5 seconds in the roundabout/
after the Tjunction.
R approximately 12 seconds before reaching
am otorway exit and approximately 4sec-
onds after the motorwa yexit
Afterwards ,the vehicle accelerates bac kto
the set speed you specified.

ATTE NTION ASSIST assesses your level of
fatigu eorlapses in concentration by taking
the following criteria into account:
R your personal driving style, e.g. steering
characteristics
R journey conditions, e.g. time of day and
length of journey
The functionality of ATTENTION ASSIST is
restricted and warnings may be delayed or
not occur at all:
R if the road condition is poor, e.g. the sur-
face is uneven or there are potholes
R if there is astron gside wind
R if you have adopted asporty driving style
with high cor nering speeds or hig hrates of
acceleration
R if you are predominantly driving slower
than 80 km/ horfaster than 180 km/h
R if you are currently using COMAND APS or
making atelephone call with it
R if the tim ehas been set incorrectly
R in active driving situations, such as when
you change lanes or change your speed

Important safety guidelines Blin
dSpot Assist uses aradar sensor system
to monitor the areas on both sides of your
vehicle. Blin dSpot Assist provides assistance
at speeds higher than 30 km/h. Awarning
display in the exterior mirrors draws your
attention to vehicles in the monitored area. If
you then indicat eaturn toward sthat side
before changing lane, you will also receive
visual and audible collision warnings. For this
purpose, Blind Spot Assist uses sensor sinthe
rea rbumper. G
Risk of accident
Blind Spot Assis tiso nly an aid designe dto
assis tdriving. It may fail to detec tsome vehi-
cles and is no substitute for attentiv edriving.
Blind Spo tAssist can notd etect road and traf-
fic conditions. It may fail to detect narrow
vehicles, such as motor cycles or bicycles ,or
only detec tthem too late.
Monitoring ma ybeaffected by dirty sensors,
stro ngspra yorp oor visibility caused by snow,
rai norm ist, 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 injur eyoursel fand others.
The radar senso rsystem is automatically
deactivated near radio telescope facilities
(Y page 324).
For Blind Spot Assist to assist you when driv-
ing, the radar sensor syste mmust be activa-
ted (Y page 208 )and operational. Monitoring range of the sensors Blind Spot Assist monitors the area up to
three metres behind your vehicl
eand directly
next to your vehicl easshown in the diagram. Sid
eview, Coupé (example) G
Risk of accident
Blind Spot Assist monitors certain areas in the
immediate vicinit yofyour vehicle. Vehicles
that approach and driv epast at high speeds
are not detected. There is no display and no
warning.
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 in
different lanes .This ma ybethe case if vehi-
cles ar edrivin gatt he edge of their lan ethat
is furthest away from your vehicle.
Always pay attention to traffic conditions and
your surroundings. Otherwise, you ma yfail to
recognise dangers in time, cause an accident
and injure yourself and others.
If the lanes are narrow, the system may be
unable to distinguish the neighbouring lane
from the one beyond it. For this reason, vehi-
cles in the farther lane may be indicated,
especially if the vehicles are driving in astag-
gered formation in different lanes .Inparticu- 184

warnings may be issued in err or when driving

integrate dinto the sides of the rear bumper.
Make sure that the bumpe risfree from dirt,

the rada rsensors must not be covered by

Information and warning display :
Yellow indicator lamp/red warnin glamp
When Blind Spot Assis tisa ctivated, indicator
lamp :in the exterior mirrors lights up in
yellow at speed sofupto30km/ h.At speeds
above 30 km/h, the indicator lamp goe sout
and Blind Spo tAssist is operational.
If av ehicle is detected within the monitoring
range of Blin dSpot Assist at speeds above
30 km/h, warning lamp :on the corre-
sponding side lights up red. This warning is
always issued when avehicle enter sthe blind
spot monitoring range from behind or from
the side. When you overtak eavehicle, the
warning only occurs if the difference in speed
is less than 12 km/h. The yellow indicator lam
pgoes out 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-
rio rm irror sare yel low.Vehicles in the moni-
toring range are then not indicated.
