Function
When switched on, the Blind Spot Monitor is active from a speed of approx. 15 km/h (9 mph).
In the following driving situations, the yellow indicator lamp will light up in the corresponding
exterior mirror:

Fig. 124
If your vehicle is being overtaken.
When overtaking another vehicle with a speed difference of up to approximately 10 km/h (6 mph).
No display will be shown if the takeover manoeuvre is much faster.
If a vehicle is detected in the blind spot and the turn signal is additionally activated in the direction
of the detected vehicle
⇒
, the yellow indicator lamp will flash.
In vehicles with the lane keeping system, the yellow indicator lamp
will flash even if you do not
activate the turn signal when leaving your lane, provided that the lane keeping system is switched on
(Blind Spot Monitor Plus). The driver is warned by a corrective steering intervention when changing
lanes during a possible critical situation (information level, warning level). This also occurs when the
turn signal is activated for the corresponding direction. If the steering intervention is overridden by
the driver, the steering wheel vibrates to give an additional warning.
The quicker another vehicle approaches, the earlier there is a corresponding display in the exterior
mirror.
Automatic deactivation
The radar sensors for the Blind Spot Monitor will switch off automatically if, for example, the system
detects that a radar sensor is continuously covered. This can be caused by a layer of ice or snow in
front of the radar sensor, for example.
A text message will be shown on the instrument cluster display.
If the Blind Spot Monitor has been automatically deactivated, the system cannot be activated until
the ignition has been switched off and back on again.
The Blind Spot Monitor is automatically deactivated and cannot be activated when the factory-fitted
towing bracket is electrically connected to a trailer or similar
⇒
Trailer towing . Once a trailer is
electrically connected to the vehicle and the driver pulls away, a text message appears in the
instrument cluster display to inform the driver that the Blind Spot Monitor has been deactivated.
The Blind Spot Monitor will be automatically activated again when the trailer has been unhitched
from the vehicle. This applies if the function was previously activated. The Blind Spot Monitor must
be deactivated manually if you tow a trailer using a towing bracket that was not fitted at the factory.
