General information
The Lane Tracking package consists of Blind
Spot Assist ( Y page 205) and Lane Keeping
Assist ( Y page 207).
Blind Spot Assist
Important safety notes
Blind Spot Assist uses a radar sensor system
to monitor the areas on both sides of your
vehicle. It is active at speeds above
approximately 20 mph (30 km/h). A warning
display in the exterior mirrors draws your
attention to a vehicle detected in the
monitored area. If you switch on the
corresponding turn signal before changing
lane, you will also receive visual and audible
collision warnings. For this purpose, Blind
Spot Assist uses sensors in the rear bumper.
GWarning
Blind Spot Assist is only an aid designed to
assist driving. It may fail to detect some
vehicles and is no substitute for attentive
driving.
Blind Spot Assist cannot detect road and
traffic conditions. It may fail to detect narrow
vehicles, such as motorcycles or bicycles, or
may 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
recognize dangers in time, cause an accident
and injure yourself and others.

If Blind Spot Assist is switched on, indicator
lamp : in the exterior mirrors lights up in
yellow up to a speed of 20 mph (30 km/h). At
speeds above 20 mph (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
20 mph (30 km/h), warning lamp : on the
corresponding side lights up in 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Assist is no longer active.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
the ambient light.
GWarning
Blind Spot Assist is not active at speeds under
approximately 20 mph (30 km/h). The
indicator lamps in the exterior mirrors are
yellow. Vehicles in the monitoring range are
then not indicated.
Always pay attention to traffic conditions and
your surroundings. Otherwise, you may fail to
recognize dangers in time, 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.

Active Blind Spot Assist
Important safety notes
Active Blind Spot Assist uses a radar sensor
system to monitor the side areas of your
vehicle. In addition, it uses the radar sensor
system to monitor the front area as well.
Active Blind Spot Assist is activated at speeds
above approximately 20 mph (30 km/h). A
warning lamp in the exterior mirrors calls your
attention to a vehicle or certain obstacles in
the area monitored. If you switch on the
corresponding turn signal before changing
lane, you will also receive visual and audible
collision warnings. If a risk of lateral collision
is detected, corrective braking may help you
avoid a collision.
GWarning
Active Blind Spot Assist is only an aid, and
may detect vehicles/obstacles incorrectly or
not at all.
The system may be impaired or may not
function if:
R there is poor visibility, e.g. due to snow,
rain, fog or spray.
R the rear and/or front sensors are dirty.
Active Blind Spot Assist may not detect
narrow vehicles, such as motorcycles or
bicycles, or only detect them too late. It
cannot detect vehicles that are overtaken at
a small distance and then enter the blind spot
area.
Active Blind Spot Assist cannot detect road
and traffic conditions. It is not a substitute for
attentive driving. You are responsible for the
vehicle's speed, braking in good time, and
steering correctly. Always adapt your driving
style to suit the prevailing road and weather
conditions. Always pay attention to traffic
conditions and your surroundings. Otherwise,
you may fail to recognize dangers in time,
cause an accident and injure yourself and
others.

Monitoring range
Active Blind Spot Assist monitors the area up
to 10 ft (3 m) behind your vehicle and directly
next to your vehicle as shown in the diagram.
For this purpose, Active Blind Spot Assist
uses sensors in the rear bumper.
Sedan (example)
GWarning
Active 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. No visual nor
audible warnings are emitted and the system
does not brake the vehicle to correct your
course.
Driving systems209Driving and parkingBA 212 USA, CA Edition B 2011; 1; 5, en-USdimargiVersion: 3.0.3.62010-05-20T13:33:46+02:00 - Seite 209Z
If the lanes are very wide, it may not be
possible to monitor the complete width of the
neighboring lane. For this reason, vehicles in
the next lane may not be detected, especially
if they are driving in a staggered 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
recognize dangers in time, cause an accident
and injure yourself and others.
If the lanes are narrow, the system may be
unable to distinguish the neighboring lane
from the one beyond it. For this reason, the
system may indicate vehicles in the farther
lane, especially if the vehicles are driving in a
staggered formation in different lanes. In
particular, this may be the case if the vehicles
are driving at that edge of their lane which is
nearest your vehicle. Due to the nature of the
system, warnings may be issued
unnecessarily when driving close to crash
barriers or similar solid lane borders.
Two Active Blind Spot Assist sensors are
integrated into the front and rear bumpers
respectively. An additional sensor is located
behind the cover in the radiator grill. Make
sure that the bumpers are free of dirt, ice or
slush around the sensors. The rear radar
sensors must not be covered, for example by
bicycle racks or overhanging loads. In the
event of a severe impact or damage to the
bumpers, have the function of the radar
sensors checked at a qualified specialist
workshop, e.g. an authorized Mercedes-Benz
Center. Active Blind Spot Assist may
otherwise fail to work correctly.
Indicator and warning display:Yellow indicator lamp/red warning lamp
If Active Blind Spot Assist is switched on,
indicator lamp : in the exterior mirrors lights
up in yellow up to a speed of 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 of Blind Spot Assist at speeds above
20 mph (30 km/h), warning lamp : on the
corresponding side lights up in 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. Active Blind Spot Assist is
then no longer active.
The brightness of the indicator/warning
lamps is adjusted automatically according to
the ambient light.
GWarning
Active Blind Spot Assist is not active at speeds
lower than 20 mph (30 km/h). The indicator
lamps in the exterior mirrors are yellow.
Vehicles in the monitoring range are then not
indicated.
Always pay attention to traffic conditions and
your surroundings. Otherwise, you may fail to
recognize dangers in time, cause an accident
and injure yourself and others.

Optical and acoustic collision warning
When you switch on the appropriate turn
signals to change lanes and a vehicle is
detected in the side monitoring range of
Active Blind Spot Assist, you receive an
optical and acoustic collision warning. You
then hear a double warning tone and 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.
Course-correcting brake application
If Active Blind Spot Assist detects a risk of
collision in the monitoring range, under
certain circumstances, it will brake the
vehicle briefly on one side. This is designed to
help you avoid a collision.
This function is available at speeds between
20 mph and 120 mph (30 km/h and
200 km/h).
When a course-correcting brake application
occurs, red warning lamp : flashes in the
exterior mirror and the following is shown in
the multifunction display, for example:GWarning
Active Blind Spot Assist is only an aid
designed to assist driving. It is not a substitute
for attentive driving. In some cases, the
course-correcting brake application is not
sufficient to avoid a collision. In such a case,
you must steer, brake or accelerate.
In very rare cases, the system may
erroneously detect a danger of collision in the
area of crash barriers or similar lane borders
and apply the brakes. Active Blind Spot Assist
does not detect all traffic situations and road
users. Always make sure that there is
sufficient distance to the side for other traffic
or obstacles. An inappropriate brake
application may be interrupted at any time if
you steer slightly in the opposite direction or
accelerate.
You are responsible for the vehicle's speed,
braking in good time, and steering correctly.
Always adapt your driving style to suit the
prevailing road and weather conditions.
Always pay attention to traffic conditions and
your surroundings. Otherwise, you may fail to
recognize dangers in time, cause an accident
and injure yourself and others.
Either a very slight, course-correcting brake
application, or none at all, may occur if:
R other vehicles and/or objects, such as
crash barriers, are detected in the
immediate vicinity of your vehicle.
R a vehicle approaches you too closely at the
side.
R you have adopted a sporty driving style with
high cornering speeds.
R you clearly brake or accelerate.
R a driving safety system intervenes, such as
ESP ®
or PRE-SAFE ®
Brake.
R ESP ®
is deactivated.
R a loss of tire pressure or a defective tire has
been detected and shown in the display.
