For Blind Spot Assist to help you when driving,
the radar sensor system must be switched on
and operational. G
Risk of accident
Blind Spot Assist cannot detect road and traf-
fic conditions.
Blind Spot Assist may not detect narrow vehi-
cles, such as motorcycles or bicycles, or only
detect them too late.
Monitoring may be affected by dirty sensors,
strong spray 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.
Monitoring range of the sensors
Blind Spot Assist monitors the area up to
three metres behind your vehicle and directly
next to your vehicle as shown in the diagram. Example: Saloon
G
Risk of accident
Blind Spot Assist monitors certain areas in the
immediate vicinity of your vehicle. Vehicles
that approach and drive past 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 a staggered formation in
different lanes. This may be the case if vehi-
cles 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, 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 a stag-
gered formation in different lanes. This may
be the case if vehicles are driving at the edge
of the lane that is nearest your vehicle. Due
to the nature of the system, warnings may be
issued in error when driving close to crash
barriers or similar solid lane borders.
The two sensors for Blind Spot Assist are
integrated into the sides of the rear bumper.
Make sure that the bumper is free from dirt,
ice or slush around the sensors. For example,
the radar sensors must not be covered 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 a qualified specialist
workshop, e.g. a Mercedes-Benz Service
Centre. Otherwise, Blind Spot Assist may not
work properly. 168

Lane Keeping Assist monitors the area in
front of your vehicle by means of a camera at
the top of the windscreen. :
Lane Keeping Assist camera
In order that you are warned only when nec-
essary and in good time if you cross the lane
marking, the system recognises certain con-
ditions and warns you accordingly.
The warning occurs earlier if:
R you cut a corner on the outside.
R the road has very wide lanes, e.g. a motor-
way.
R the system recognises solid lane markings,
as crossing these often results in a critical
situation, e.g. in the case of hard shoulders
or crash barriers.
The warning occurs later if:
R the road has narrow lanes.
R you cut a corner on the inside.
No warning occurs if:
R you actively steer, brake or depress the
accelerator pedal, e.g. when changing lane,
overtaking, accelerating or leaving the
motorway.
R you cut the corner on a sharp bend.
R you drive around a very sharp bend.
R you switch on the turn signals. In this event
the warnings are suppressed for a certain
period of time.
R a driving safety system intervenes, such as
ABS, BAS or ESP ®
. G
Risk of accident
Lane Keeping Assist does not keep your vehi-
cle in its lane. It is only an aid and may detect
the lane markings on the road incorrectly or
not at all.
The system may be impaired or may not func-
tion if:
R there is poor visibility, e.g. due to snow,
rain, fog or spray.
R there is glare, e.g. from the sun or from
oncoming traffic.
R the windscreen is dirty, misted up or cov-
ered, for instance by a sticker, in the vicinity
of the camera.
R there are no lane markings.
R the lane markings are worn away, dark or
covered up, e.g. by dirt or snow.
R the distance to the vehicle in front is too
short.
R there are ambiguous lane markings on the
road, e.g. near roadworks.
R there are short-term changes to the mark-
ings, e.g. filter lanes or motorway exits.
R the road is narrow and winding.
Lane Keeping Assist cannot detect road and
traffic conditions. It is not a substitute for
attentive driving.
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.

Risk of accident
If you switch off the "Cooling with air dehu-
midification" function, the air inside the vehi-
cle will not be cooled (in warm weather) or
dehumidified. The windows could mist up
more quickly. This may prevent you from
observing the traffic conditions and thereby
cause an accident.

the vehicle when Thermatic is in cooling
mode.
