The Active Driving Assistance package
consists of DISTRONIC PLUS (
Y
page 293),
Active Blind Spot Assist (

Active Lane Keeping Assist (

Active Blind Spot Assist
Important safety guidelines
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. Active Blind
Spot Assist provides assistance at speeds
higher than about 20 mph (30 km/h). A
warning lamp in the exterior mirror calls your
attention to a vehicle or to certain obstacles
in the area monitored. If you then indicate a
turn towards that side before changing lanes,
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.
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
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.
R
the road is narrow and winding.
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
