2011 MERCEDES-BENZ S-Class turn signal

Active Blind Spot Assist (Y page 356) and
Active Lane Keeping Assist ( Y page 359).
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 active 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.

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
lateral 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 in the range 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 message, for
example, appears in the multifunction
display:
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:
Rother vehicles and/or objects, such as
crash barriers, are detected in the
immediate vicinity of your vehicle.
Ra vehicle approaches you too closely at the
side.
Ryou have adopted a sporty driving style with
high cornering speeds.
Ryou brake or accelerate decisively.
Ra driving safety system intervenes, such as
ESP® or PRE-SAFE® Brake.
RESP® is deactivated.
Ra loss of tire pressure or a defective tire has
been detected and displayed.
Activating Active Blind Spot Assist
XMake sure that the radar sensor system
(Y page 378) and Active Blind Spot Assist
(Y page 376) are activated in the on-board
computer.
XTurn the key to position 2 in the ignition
lock.
Warning lamps : light up red in the
exterior mirrors for approximately 1.5
seconds and then turn yellow.
358Driving systemsDriving and parking

No warning vibration occurs if:
Ryou clearly and actively steer, brake, or
accelerate.
Ryou cut the corner on a sharp bend.
Ra driving safety system intervenes, such as
ABS, BAS or ESP®.
Ryou switch on the turn signals. In this event,
the warnings are suppressed for a certain
period of time.
Lane-correcting brake application
If you leave your lane under certain
circumstances, the vehicle will brake briefly
on one side. This is designed to help you bring
the vehicle back into the original lane.
This function is available in the range between
40 mph and 120 mph (60 km/h and
200 km/h).
A lane-correcting brake application can only
be made after driving over a solid,
recognizable lane marking. You will be
warned beforehand by means of an
intermittent vibration in the steering wheel.
In addition, a lane with lane markings on both
sides must be recognized. The brake
application also slightly reduces driving
speed.
If a lane-correcting brake application occurs,
the following message appears in the
multifunction display:
iA further lane-correcting brake
application can only occur after your
vehicle has returned to the original lane.
GWarning
Active Lane Keeping Assist does not keep
your vehicle in its lane. It is only an aid
designed to assist driving. It is not a substitute
for attentive driving. In some cases, the lane-
correcting brake application is not sufficient
to bring your vehicle back to the original lane.
In such cases, you must steer the vehicle
yourself to ensure that it does not leave the
lane.
Active Lane Keeping Assist does not detect
road and traffic conditions. Always make sure
that there is sufficient distance to the side for
other traffic or obstacles. In rare cases,
unclear markings or particular structures on
the roadway can be recognized as solid lane
markings. An inappropriate brake application,
e.g. after intentionally driving over a solid lane
marking, may be interrupted at any time by
steering slightly in the opposite direction.
Active Lane Keeping Assist cannot take
account of weather conditions.
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.
No lane-correcting brake application occurs
if:
Ryou clearly and actively steer, brake, or
accelerate.

view mirror with the garage door system
receiver after programming.
You will find further information in the
garage door opening system's operating
instructions, e.g. the sections on
"Synchronizing the transmitter" or
"Registering a new transmitter". You can
also call the hotline mentioned above.
Notes on programming the remote
control
Canadian radio frequency laws require a
"break" (or interruption) of the transmission
signals a few seconds after broadcasting.
Therefore, these signals may not last long
enough for the integrated remote control to
recognize the signal during programming.
Comparable with Canadian law, some U.S.
garage door openers also have a built-in
"interruption".
If you live in Canada or have difficulties
programming the garage door opener
(regardless of where you live) when using the
programming steps (see above), proceed as
follows:XPress transmitter button ( ;, = or ?) and
hold it down during the following steps until
the setup has been completed
successfully.XAt the same time, press transmitter button
B of the garage door remote control for
two seconds, then release it for two
seconds, then press it again for two
seconds.XRepeat this sequence on transmitter
button B of the garage door remote
control until the frequency signal has been
saved.XIf the setup procedure is successful,
indicator lamp : flashes once slowly and
goes out after a few seconds.XContinue with the other programming
steps (see above).Problems when programming
If you have problems when programming the
integrated remote control, please note the
following:
R Check the transmitter frequency of garage
door remote control A (which can usually
be found on the rear of the remote control).
The integrated remote control is
compatible with devices that operate at
frequencies between 280 and 390 MHz.
R Replace the batteries in garage door
remote control A. This increases the
likelihood of garage door remote
control A sending a strong and precise
signal to the integrated remote control on
the rear-view mirror.
R When programming, hold garage door
remote control A at varying distances and
angles from the transmitter button which
you are programming. Try different angles
at a distance of 2 to 12 inches (5 to 30 cm)
or the same angle at different distances.
R If there is another garage door remote
control for the same device, perform the
programming steps again using the remote
control. Before performing these steps,
make sure that new batteries have been
installed in the garage door remote control.
R Align the antenna cable of the garage door
opener unit. This can improve signal
reception/transmission.
Opening or closing the garage door
Once programmed, the integrated remote
control will assume the function of the garage
door system's remote control. Please also
read the operating instructions for the garage
door system.
XTurn the SmartKey to position 2 in the
ignition lock.XPress transmitter button ;, = or ? in the
overhead control panel that you have
programmed to operate the garage door.
