Active Blind Spot Assist Important safety notes
Active Blind Spot Assist uses
aradar sensor
system to monitor the side areas of your vehi- cle that are behind the driver.
Awarning dis-
play in th eexteri or mirror sdraws your atten-
tio ntod etected vehicles in the monitored
area. If you then switch on the corresponding
turn signal to change lane, you will also
receive avisual and acoustic collision warn-
ing. If arisk of lateral collision is detected,
corrective braking may help you avoid acol-
lision. To support the course-correcting brake
application, Active Blind Spot Assist also uses
the forward-facin gradar sensor system.
Active Blind Spot Assist provides assistance
at speeds higher than about 30 km/h. G
WARNING
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 func-
tion 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 nar-
row vehicles, such as motorcycles or bicycles,
or only detect them too late. It cannot detect
vehicles which are overtaken at asmall dis-
tancea nd then enter the blind spot area.
Active Blind Spot Assist cannot detect road

Course-correcting brak eapplication
If Active Blind Spot Assist detects arisk of a
lateral collision in the monitoring range, a
course-correcting brake application is carried
out. This is designed to help you avoid acol-
lision.

WARNING
Activ eBlindS pot Assist is only an aid
designed to assist driving. It is not asubstitute
for attentive driving. Automatic braking by the
system may not always be sufficien ttoavoid
ac ollision. In such cases, you need to steer,
brake or accelerate yourself.
In very rare cases, the system may detect a
risk of collision where there is none and brake
in error near crash barriers or similar road
boundaries. Active Blind Spot Assist cannot
detect all traffic situations and road users.
Ensure at all times that there is sufficient lat-
eral distance between you and other road
users or obstacles. You can, for example,
countersteer gently or depress the accelera-
tor pedal at any time to cancel inappropriate
braking action.
You are responsible for the vehicle's speed,
correc tsteerin gand for braking in good time.
Alway sadapt your drivin gstyle to suit the
prevailing road and weather conditions.
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.
Either avery slight course-correcting brake
application, or none at all, may occur if:
R there are vehicles or obstacles, e.g. crash
barriers, on both sides of your vehicle.
R av ehicle approaches too closely on the
side.
R you have adopted asporty driving style with
high cornering speeds.
R you brake or accelerate decisively. Driving systems

tute for attentive driving. You are responsible
for the vehicle's speed ,braking in good time,
and steering correctly. Always adapt your
driving style to suitt he prevailing road and
weather conditions.A lways pay attention to
traffic condition sand your surroundings. Oth-
erwise, you may fail to recognise danger sin

Warning vibration in th esteering wheel
Aw arnin gmay be given if afront wheel
passes over alane marking. You will be
warned by way of intermitten tvibrations in
the steerin gwheel for up to 1. 5seconds.
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 vibration occur searlier if:
R you approach the outer lane markin gona

eapplication
If you leave your lane under certain circum-
stances, the vehicle will brake briefly on one
side. This is designed to help you bring the
vehicle back intot he original lane.
This function is available in the range between
60 km/ha nd 200 km/h.
Al ane-correctingb rake application can only
be made after driving over asolid, recognis-
able lane marking. Befor ethis, awarning
must be emitted by means of intermittent
vibration in the steering wheel. In addition, a
lane with lane markings on both sides must
be recognised. The brake application also
slightly reduces driving speed.
If al ane-correcting brake application occurs,
the following message appears in the multi-
function display: Example: vehicles with automatic transmission
i
Afurther lane-correcting brake applica-
tion can only occur after your vehicle has
returned to the original lane. G
WARNING
Active Lane Keeping Assist does not keep
your vehicle in its lane. It is only an aid
designed to assist driving. It is not asubstitute
for attentive driving. Corrective braking may
not always be sufficient to return your vehicle
to its original lane. In such cases, you must
steer the vehicle yourself to ensure that it
does not leave the lane.
Active Lane Keeping Assist cannot detect the
current traffic situation or other road users.
Ensure at all times that there is sufficient lat-
eral distance between you and other road
users or obstacles. In rare cases, broken lines
or certain structures on the road surface may
be detected by the system as solid lane mark- Driving systems

i If the indicator lamp flashes green after
successful programming, the garage door
system is using arolling code. After pro-
gramming, you must synchronise the
garage door opener integrated in the rear-
view mirror with the receiver of the garage
door system.
Synchronising the rolling code
Your vehicle must be within reach of the
garage or gate opener drive. Make sure that
neither your vehicle nor any persons/objects
are present within the sweep of the door or
gate.

Problems when programming
If you have problems when programming the
integrated garage door opener, please note
the following:
R check the transmitter frequency of garage
door remote control A(this can usually be
found on the rear of the remote control).
R change the batteries in garage door remote
control A.This increases the likelihood
that garage door remote control Awill
send astronga nd precise signal to the
integrated remote control in the rear-view
mirror.
R when programming, hold garage door
remote control Aat different distances
and angles from the transmitter button that
you are programming. Try various angles at
ad istance of between 5and 30 cm or the
same angle but varying distances.
R if there is another remote control for the
same garage door drive, perform the pro-
gramming steps again using this remote
control. Before performing these steps,
make sure that new batteries have been
fitted in the garage door drive remote con-
trol.
R note that some remote controls transmit
only for alimited period (the indicator lamp
on the remote control goes out). Press the
button on the remote control again before
transmission ends.
R align the aerial cable of the garage door
opener unit. This can improve signal recep-
tion/transmission. 276
