2014 MERCEDES-BENZ CLS turn signal

The brightness of the indicator/warning
lamps is adjusted automatically accordingto
the ambient light.
Visual and acoustic collision warning
If you switch on the turn signals to change
lanes andavehicle is detected in the side
monitoring range, you receiveavisual and
acoustic collision warning. You then hear a
double warning toneand red warning
lampflashes. 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
GWARNING
Acourse-correctingbrake application cannot
alwayspreventacollision. There isarisk of
an accident.
Always steer, brake or accelerate yourself,
especially if Active Blind Spot Assist warns
you or makesacourse-correcting brake
application. Always maintainasafe distance
at the sides.
If Active Blind Spot Assist detectsarisk 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.
Ifacourse-correcting brake application
occurs, red warning lampflashes in the
exterior mirror andadual warning tone
sounds. In addition, the display shown in the
lower image appears in the multifunction
display.
In very rare cases, the system may make an
inappropriate brake application. An
inappropriate course-correcting brake
application may be interrupted at any time if
you steer slightly in the opposite direction or
accelerate, for example.
The course-correcting brake application is
available in the speed range between
20 mph (30 km/h) and 120 mph (200 km/h).
Either no braking application, oracourse-
correcting brake application adapted to the
driving situation occurs if:
Rthere are vehicles or obstacles, e.g. crash
barriers, located on both sides of your
vehicle.
Ravehicle approaches you too closely at the
side.
Ryou have adoptedasporty driving style with
high cornering speeds.
Ryou clearly brake or accelerate.
Radriving safety system intervenes, e.g.
ESP®or PRE-SAFE®Brake.
RESP®is switched off.
Raloss of tire pressure oradefectivetire is
detected.
Switching on Active Blind Spot Assist
XMake sure that the radar sensor system
(Ypage 232) and Active Blind Spot Assist
(Ypage 228) are activated in the on-board
computer.
XTurn the SmartKey to position2in the
ignition lock.

If no vehicle is detected in the adjacent lane
and there are broken lane markings detected,
no lane-correcting brake application is made.
Warning vibration in the steering wheel
Awarning may be given ifafront wheel
passes overalane marking. It will warn you
by means of intermittent vibration in the
steering wheel for up to 1.5 seconds.
Lane-correcting brake application
GWARNING
Alane-correcting brake application cannot
always bring the vehicle back into the original
lane. There isarisk of an accident.
Always steer, brake or accelerate yourself,
especially if Active Lane Keeping Assist warns
you or makesalane-correcting brake
application.
GWARNING
Active Lane Keeping Assist does not detect
traffic conditionsorroad users. In very rare
cases, the system may make an inappropriate
brake application, e.g. after intentionally
driving overasolid 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.
If you leave your lane, under certain
circumstances the vehicle will brake briefly
on one side. This is meant to assist you in
bringing the vehicle back to the original lane.
Ifalane-correcting brake application occurs,
displayappears in the multifunction
display.
This function is available in the range between
40 mph and 120 mph (60 km/h and
200 km/h).
Alane-correcting brake application can only
be made after driving overasolid,
recognizable lane marking. Before this, a
warning must be given by means of
intermittent vibration in the steering wheel.
In addition,alane with lane markings on both
sides must be recognized. The brake
application also slightly reduces vehicle
speed.
iAfurther lane-correcting brake
application can only occur after your
vehicle has returned to the original lane.
No lane-correcting brake application occurs
if:
Ryou clearly and actively steer, brake or
accelerate.
Ryou cut the corner onasharp bend.
Ryou have switched on the turn signals.

iIf the indicator lamp flashes green after
successful programming, the garage door
system is usingarolling code. After
programming, you must synchronize the
garage door opener integrated in the rear-
view mirror with the receiver of the garage
door system.
Synchronizing the rolling code
Observe the "Important safety notes"
(Ypage 299).
Your vehicle must be within reach of the
garage door or exterior gate drive. Make sure
that neither your vehicle nor any persons/
objectsare present within the sweep of the
door or gate.

operating instructions, e.g. under
"programming of additional remote
controls").
iUsually,you now have 30seconds to
initiate the next step.
XPress previously programmed button,
$or!of the integrated garage door
opener until the door closes.
The rolling code synchronization is then
complete.
Notes on programming the remote
control
Canadianradio frequency laws require a
"break"(or interruption)ofthetransmission
signals after broadcastingforafew seconds.
Therefore, these signals may notlast long
enough for theintegratedgaragedoor
opener. The signal is notrecognized during
programming. Comparable with Canadian
law, some U.S.garage door openers also
featurea"break".

Problems when programming
If you are experiencing problems
programmingthe integrated garage door
opener on the rear-view mirror, take noteof
the following instructions:
RCheck the transmitter frequencyofgarage
door drive remotecontrol.This can
usually be found on the back of the remote
control.
The integrated garage door opener is
compatible with devices that have units
which operate in the frequency range of
280to433MHz.
RReplace the batteries in garage door
remote control.This increases the
likelihood that garage door remote control
will transmitastrongand precisesignal
to the integrated garage door openerinthe
rear-view mirror.
RWhen programming, hold remote control
at varying distances and angles from the
button that you are programming. Try
various angles atadistance between 2and
12 inches (5to 30 cm) or at the same angle
but at varying distances.
RIf another remote control for the same
garage door drive is available, repeat the
same programming steps with this remote
control. Before performing these steps,
make sure that new batteries have been
installed in garage door drive remote
control.
RNote that some remote controls only
transmit foralimited amount of time (the
indicator lamp on the remote control goes
out). Press button%on remote control
again before transmission ends.
RAlign the antennacable of the garage door
opener unit. This can improve signal
reception/transmission.
