lamp C in the exterior mirrors lights up yel-
low at speeds of up to 20 mph (30 km/h). At
speeds above 20 mph (30 km/h), the indica-
tor lamp goes out and Blind Spot Assist is
operational.
If a vehicle is detected within the blind spot
monitoring range at speeds above 20 mph
(30 km/h), warning lamp C on the corre-
sponding side lights up red. This warning is
always emitted when a vehicle enters the
blind spot monitoring range from behind or
from the side. When you overtake a vehicle,
the warning only occurs if the difference in
speed is less than 7 mph (12 km/h).
The yellow indicator lamp goes out if 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Assist is no longer active.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

Active Blind Spot Assist
General notes
Active Blin d Spo t Assist mon it ors the areas
on either side of the vehicle that are not
dire ct ly vis ible to the driver with two lateral,
rear-facing radar sensors. A warning lamp
lights up in the exterior mirrors and draws your attention to vehicles detected in the
mon it ored area. If you then switch on the cor-
respon din g turn signal to change lanes, you
will also receive a visual and audible co llisio n
warning. If a risk of lateral co llisio n is detec-
te d, correct ive braking may help you avoid a
co llisio n. Before a course-correcting brake
applic ation, Acti ve Blind Spo t Assist evalu-
ates the space in the dire ction of travel and at
the sides of the vehicle. For this, Acti ve Blind
Spot Assist uses the forward-facing radar
sensors.
Acti ve Blind Spo t Assist supports you from a
speed of approximately 20 mph (30 km/h).
Imp ortant safety notes
Acti ve Blind Spo t Assist is on ly an aid and is
not a substitute for attenti ve driving.

Indicator and warning display
C
Yellow indicator lamp/red warning lamp
Active Blind Spot Assist is not active at
speeds below approximately 20 mph
(30 km/h). Vehicles in the monitoring range
are then not indicated.
When Active Blind Spot Assist is activated,
indicator lamp C in the exterior mirrors lights
up yellow at speeds of up to 20 mph
(30 km/h). At speeds above 20 mph
(30 km/h), the indicator lamp goes out and
Active Blind Spot Assist is operational.
If a vehicle is detected within the monitoring
range at speeds above approximately 20 mph
(30 km/h), warning lamp C on the corre-
sponding side lights up red. This warning lamp
always lights up when a vehicle enters the
blind spot monitoring range from behind or
from the side. When you overtake a vehicle
with a difference in speed of less than 7 mph
(12 km/h), a delayed warning occurs.
The yellow indicator lamp goes out if reverse
gear is engaged. Active Blind Spot Assist is
not operational.
The brightness of the indicator/warning
lamps is adjusted automatically according to
the brightness of the surroundings.
Visual and acoustic collision warning
If you switch on the turn signals to change
lanes and a vehicle is detected in the side
monitoring range, you receive a visual and
acoustic collision warning. You then hear a
double warning tone and red warning lamp C
flas hes. If the turn signal remains on, detec-
ted vehicles are indicated by the flashing of red warning lamp C . There are no further
warning tones.
Course-correcting brake application
If Active Blind Spot Assist detects a risk of a
lateral collision in the monitoring range, a
course-correcting brake application is carried
out. This is meant to assist you in avoiding a
collision.
G WARNING
A course-correcting brake application cannot
always prevent a collision. There is a risk of an
accident.
Always steer, brake or accelerate yourself,
especially if Active Blin d Spot Assist warns
you or makes a course-correcting brake appli-
cation. Always maintain a safe distance at the
sides.
If a course-correcting brake application
occurs, red warning lamp C flashes in the
exterior mirror and a dual warning tone
sounds. In addition, display D underlining
the danger of a side collision appears in the
multifunction display.
In very rare cases, the system may make an
inappropriate brake application. A course-
correcting brake application may be interrup-
ted at any time if you steer slightly in the
opposite direction or accelerate.
The course-correcting brake application is
available in the speed range between 20 mph
(30 km/h) and 120 mph (200 km/h).250

Active Lane Keeping Assist monitors the area
in front of your vehicle by means of camera C
at the top of the windshield. Active Lane
Keeping Assist detects lane markings on the
road and warns you before you leave your
lane unintentionally. If you do not react to the
warning, a lane-correcting application of the
brakes can bring the vehicle back into the
original lane.
This function is available in a speed range
between 40 mph and 120 mph (60 km/h and
200 km/h).
For Active Lane Keeping Assist to assist you
when driving, the radar sensor system must
be operational
Important safety notes
If you fail to adapt your driving style, Active
Lane Keeping Assist can neither reduce the
risk of accident nor override the laws of phys-
ics. Active Lane Keeping Assist cannot take
into account road, weather or traffic condi-
tions. Active Lane Keeping Assist is only an
aid. You are responsible for the distance to
the vehicle in front, for vehicle speed, for
braking in good time and for staying in your
lane.
Active Lane Keeping Assist cannot continu-
ously keep your vehicle in its lane.
G WARNING
Active Lane Keeping Assist cannot always
clearly detect lane markings.Driving system s 251
Dr ivi ng an d parking Z

In such cases, Active Lane Keeping Assist
can: R
give an unnecessary warning and then
make a course-correcting brake application
to the vehicle R
not give a warning or intervene
There is a risk of an accident.
Always pay particular attention to the traffic
situation and keep within the lane, especially
if Active Lane Keeping Assist alerts you. Ter-
minate the intervention in a non-critical driv-
ing situation.
The system may be impaired or may not func-
tion if: R
there is poor visibility, e.g. due to insuffi-
cient illumination of the road, or due to
snow, rain, fog or spray R
there is glare, e.g. from oncoming traffic,
the sun or reflections (e.g. when the road
surface is wet) R
the windshield is dirty, fogged up, damaged
or covered, for instance by a sticker, in the
vicinity of the camera R
there are no, several or unclear lane mark-
ings for a lane, e.g. in areas with road con-
struction work 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
small and the lane markings thus cannot be
detected R
the lane markings change quickly, e.g.
lanes branch off, cross one another or
merge R
the road is narrow and winding R
there are highly variable shade conditions
on the roadway R
no vehicle is detected in the adjacent lane
and there are broken lane markings
Warning vibration in the steering wheel
A warning may be given if a front wheel
passes over a lane marking. It will warn you by means of intermittent vibration in the steer-
ing wheel for up to 1.5 seconds.
In order that you are warned only when nec-
essary and in good time if you cross the lane
marking, the system recognizes certain con-
ditions and warns you accordingly.
The warning vibration occurs earlier if: R
you approach the outer lane marking on a
bend. R
the road has very wide lanes, e.g. a high-
way. R
the system recognizes solid lane markings.
The warning vibration occurs later if: R
the road has narrow lanes. R
you cut the corner on a bend.
Lane-correcting brake application
G WARNING
A lane-correcting brake application cannot
always bring the vehicle back into the original
lane. There is a risk of an accident.
Always steer, brake or accelerate yourself,
especially if Active Lane Keeping Assist warns
you or makes a lane-correcting brake appli-
cation.
G WARNING
Active Lane Keeping Assist does not detect
traffic conditions or road users. In very rare
cases, the system may make an inappropriate
brake application, e.g. after intentionally driv-
ing over a solid lane marking. There is a risk of
an accident.
An inappropriate brake application may be
interrupted at any time if you steer slightly in
the opposite direction. Always make sure that
there is sufficient distance on the side for
other traffic or obstacles.252
