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 objectsint
he 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.
! If unavoidable, you should drive over
obstacles such as curbs slowly and not at
a sharp angle. Otherwise, you may damage
the wheels or tires.
Active Parking Assist may possibly indicate
parking spaces which are not suitable for
parking, for example:
R where parking or stopping is prohibited
R in front of driveways or entrances and exits
R on unsuitable surfaces
Parking tips:
R On narrow roads, drive as close to the
parking space as possible.
R Parking spaces that are littered, overgrown
or partially occupied by trailer drawbars
might be identified incorrectly or not at all. 206

General notes
Active Blind Spot Assist uses a radar sensor
system to monitor the side areas of your
vehicle which are behind the driver. Awarning
display in the exterior mirrors draws your
attentio nto 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:
R
activated(Y page 235)
R operational
Monitoring area
In particular, the detection of obstacles can
be impaired if:
R there is dirt on the sensors or anything else
covering the sensors.
R there is poor visibility, e.g. due to fog, heavy
rain or snow.
R a narrow vehicle traveling in front, e.g. a
motorbike or bicycle.
R the road has very wide lanes.
R the road has narrow lanes.
R you are not driving in the middle of the lane.
R there are barriers or similar lane borders.
Vehicles in the monitoring range are then not
indicated. Active Blind Spot Assist monitors the area up
to 10 ft
(3.0m) behind your vehicle and
directly next to your vehicle, as shown in the
diagram .For this purpose, Active Blind Spot
Assist uses radar sensors in the rear bumper. Driving systems
215Driving and parking Z

If the lanes are narrow, vehicles driving in the
lane beyond the lane next to yourv ehicle 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.
Due to the nature of the system:
R warnings may be issued in error when
driving close to crash barriers or similar
solid lane borders.
R warnings may be interrupted when driving
alongside particularly long vehicles, e.g.
trucks, for a prolonged time.
Two Active Blind Spot Assist radar sensors
are integrated into the fron tand rea rbumpers
respectively. An additional radar sensor is
located behind the 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 no tbe 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.
Indicator and warning display 0002
Yellow indicator lamp/red warning lamp
Active Blind Spot Assist is not active at
speeds below approximately 20 mph
(30 km/h). Vehicles in the monitoring range
are then not indicated.
When Active Blind Spot Assist is activated,
indicator lamp 0002in the exterior mirrors lights up yellow at speeds of up to
20 mph(30km/h). At speeds above 20 mph
(30km/h), the indicator lamp goes out and
Active Blind Spot Assist is operational.
If a vehicle is detected within the monitoring
range of Blind Spot Assist at speeds above
20 mph (30km/h), warning lamp
0002on the
corresponding side lights up red. This warning
is always given when a vehicle enters the
blind spot monitoring range from behind or
from the side. When you overtake a vehicle,
the warning only occurs if the difference in
speed is less than 7mph (12km/h).
The yellow indicator lamp goes out if reverse
gear is engaged. In this event, Active Blind
Spot Assist is no longer active.
The brightness of the indicator/warning
lamps is adjusted automatically according to
the ambient light.
Visual and acoustic collision warning When you switch on the turn signals to
change lanes and a vehicle is detected in the
side monitoring range, you receive a visual
and acoustic collision warning
.You then hear
a double warning tone and red warning
lamp 0002flashes. If the turn signal remains on,
detected vehicles are indicated by the
flashing of red warning lamp 0002.There are no
further warning tones. 216

Course-correcting brake application
G
WARNING
Ac ourse-correcting brake application cannot
always prevent a collision. There is a risk of
an accident.
Always steer, brake or accelerate yourself,
especially if Active Blind Spot Assist warns
you or makes a course-correcting brake
application. Always maintain a safe distance
at the sides. G
WARNING
Active Blind Spot Assist does not detect all
traffic situations and road users. In very rare
cases, the system may make an inappropriate
brake application. 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 or accelerate. Always
make sure that there is sufficient distance on
the side for other traffic or obstacles. If a course-correcting brake application
occurs, red warning lamp
0002flashes in the exterior mirror and a dual warning tone
sounds. In addition, display
0003appears 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) and120 mph (200km/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.
