Use Active Parking Assist for parking spaces:
R that are parallel to the direction of travel
R that are on straight roads, not bends
R that are on the same level as the road, e.g.
not on the pavement Important safety notes Active Parking Assist is merely an aid. It is not
a replacement for your attention to your
immediate surroundings. You are always
responsible for safe maneuvering, parking
and exiting a parking space. When
maneuvering, parking or pulling out of a
parking space, make sure that there are no
persons, animals or objects in the area in
which you are maneuvering.
G
WARNING
The vehicle swings out when parking and in
doing so could cross into the opposite lane.
This could result in a collision with another
road user. There is a risk of an accident.
Pay attention to other road users when
parking. Stop the vehicle if necessary or
cancel the Active Parking Assist parking
procedure. 206

General notes The Active Driving Assistance package
consists of DISTRONIC PLUS (Y
page 186),
Active Blind Spot Assist (Y page 218) and
Active Lane Keeping Assist (Y page 221).
Active Blind Spot Assist General notes
Active Blind Spot Assist uses a radar sensor
system to monitor the side areas of your
vehicle which are behind the driver. A warning
display in the exterior mirrors draws your
attention to vehicles detected in the
monitored area. If you then switch on the
corresponding turn signal to change lanes,
you will also receive an optical and audible
collision warning. If a risk of lateral collision
is detected, corrective braking may help you avoid a collision. To support the course-
correcting brake application, Active Blind
Spot Assist also uses the forward-facing radar
sensor system.
Active Blind Spot Assist supports you from a
speed of approximately 20 mph (30 km/h).
For Active Blind Spot Assist to assist you
when driving, the radar sensor system must
be operational.
Important safety notes
Active Blind Spot Assist is only an aid. It may
fail to detect some vehicles and is no
substitute for attentive driving. G
WARNING
Active Blind Spot Assist does not react to:
R vehicles overtaken too closely on the side,
placing them in the blind spot area
R vehicles which approach with a large speed
differential and overtake your vehicle 218
Driving systemsDriving and parking

As a result, Active Blind Spot Assist may
neither give warnings nor intervene in such
situations. There is a risk of an accident.
Always observe the traffic conditions
carefully, and maintain a safe lateral distance.

Radar sensors
The Active Blind Spot Assist radar sensors are
integrated into the front and rear bumpers
and behind a cover in the radiator grill. Make
sure that the bumpers and the cover in the
radiator grill are free of dirt, ice or slush. The
rear sensors must not be covered, for
example by cycle racks or overhanging cargo.
Following a severe impact or in the event of
damage to the bumpers, have the function of
the radar sensors checked at a qualified
specialist workshop. Active Blind Spot Assist
may otherwise no longer work properly. Monitoring area G
WARNING
Active Blind Spot Assist does not detect all
traffic situations and road users. There is a
risk of an accident.
Always make sure that there is sufficient
distance on the side for other traffic or
obstacles. Active Blind Spot Assist monitors the area up
to 10 ft (3.0 m) behind your vehicle and
directly next to your vehicle, as shown in the
diagram.
The detection of obstacles can be impaired in
the case of:
R
dirt on the sensors or anything else
covering the sensors
R poor visibility, e.g. due to rain, snow or
spray
Vehicles in the monitoring range are then not
indicated or indicated with a delay.
Active Blind Spot Assist may not detect
narrow vehicles, such as motorcycles or
bicycles, or may only detect them too late.
If the lanes are narrow, vehicles driving in the
lane beyond the lane next to your vehicle may
be indicated, especially if the vehicles are not
driving in the middle of their lane. This may
be the case if there are vehicles driving at the
inner edge of their lanes. Driving systems
219Driving and parking Z

If a course-correcting brake application
occurs, red warning lamp 0043flashes in the
exterior mirror and a dual warning tone
sounds. In addition, display 0044appears in the
multifunction display.
If Active Blind Spot Assist detects a risk 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.
The course-correcting brake application is
available in the speed range between
20 mph (30 km/h) and 120 mph (200 km/h).
Either a very slight course-correcting brake
application, or none at all, may occur if:
R there are vehicles or obstacles, e.g. crash
barriers, located on both sides of your
vehicle.
R a vehicle approaches you too closely at the
side.
R you have adopted a sporty driving style with
high cornering speeds.
R you clearly brake or accelerate. R
a driving safety system intervenes, e.g.
ESP ®
or PRE-SAFE ®
Brake.
R ESP ®
is switched off.
R a loss of tire pressure or a defective tire is
detected.
