General notes Active Parking Assist is an electronic parking
aid with ultrasound. It measures the road on
both sides of the vehicle.
Aparking symbol
indicates a suitable parking space. Active
steering interventio ncan assis tyou during
parking.
You may also use PARKTRONIC
(Y page 213).
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 object
sinthe area in
which you are maneuvering.
When PARKTRONIC is switched off, Active
Parking Assist is also unavailable. G
WARNING
While parking or pulling out of a parking
space, the vehicle swings out and can drive
onto areas of the oncoming lane. This could
result in a collision with another road user.
There is a risk of an accident.
Pay attention to other road users. 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. 216
Driving systemsDriving and parking
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 tha tare littered or
overgrow nmight be identified or measured
incorrectly.
R Parking spaces that are partially occupied
by trailer drawbars might not be identified
as such or be measured incorrectly.
R Snowfall or heavy rain may lead to a parking
space being measured inaccurately.
R Pay attention to the PARKTRONIC
(Y page 214 )warning messages during the
parking procedure.
R At any time, you can intervene in the
steering procedure to correct it. Active
Parking Assist will then be canceled.
R When transporting a load which protrudes
from your vehicle, you should no tuse
Active Parking Assist.
R Never use Active Parking Assist when snow
chains are installed.
R Make sure that the tire pressures are
always correct.T his hasadirec tinfluence
on the parking characteristics of the
vehicle.
Use Active Parking Assist for parking spaces:
R tha tare 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
Detecting parking spaces Objects located above the height range of
Active Parking Assist will not be detected
when the parking space is measured. These
are not taken into account when the parking procedure is calculated, e.g. overhanging
loads, tail sections or loading ramps of goods
vehicles. G
WARNING
If there are objects above the detection range,
Active Parking Assist may turn prematurely.
You may cause a collision as a result. There is
a risk of an accident.
If there are objects above the detection range,
stop and deactivate Active Parking Assist.
For further information on the detection
range (Y page 214).
Active Parking Assist does not support you
with parking spaces parallel to the direction
of travel if:
R the parking space is on acurb
R the system reads the parking space as
being blocked, for example by foliage or
grass paving blocks
R the area is too small for the vehicle to
maneuver into
R the parking space is bordered by an
obstacle, e.g. a tree, a post or a trailer 0002

system is operational at speeds of up to
approximately 22 mph (35 km/h). While in
operation, the system independently locates
and measures parking spaces on both sides
of the vehicle. Driving systems

Once you have exited the parking space
completely, the steering wheel is moved to
the straight-ahead position. You hear a tone
and the
Park Assist Switched Off message appears in the multifunction
display. You will then have to steer and merge
into traffic on your own. PARKTRONIC is still
available. You can take over the steering,
before the vehicle has exited the parking
space completely. This is useful, for example
when you recognize that it is already possible
to pull out of the parking space.

atrailer For vehicles with a trailer tow hitch, the
minimum length for parking spaces is slightly
increased.
If you have attached a trailer to your vehicle,
you should not use Active Parking Assist.

General notes The 360° camera is a system consisting of
four cameras.
The system analyzes images from the
following cameras:
R Rear view camera
R Front camera
R Two cameras in the exterior rear view
mirrors
The cameras capture the immediate
surroundings of the vehicle .The system
supports you, e.g. when parking or if vision is
restricted at an exit.
The 360° camera images can be shown in full
screen mode or in seven different split-screen
views on the COMAND display. Asplit-screen
view also includes a top view of the vehicle.
This view is calculated from the data supplied
by the installed cameras (virtual camera).
The seven split-screen views are:
R top view and picture from the rear view
camera (130 °viewing angle)
R top view and picture fro mthe front camera
(without displaying the maximum steering
wheel angle)
R top view and enlarged rear view R
top view and enlarged front view
R top view and trailer view (vehicles with
trailer tow hitch)
R top view and pictures from the rearward
facing mirror cameras (rear wheel view)
R top view and pictures from the forward
facing mirror cameras (front wheel view)
i The top view and trailer view are available
for vehicles equipped with a trailer tow
hitch.
When the function is active and you shift the
transmission from position Dor Rto N, you
see the previous view in the COMAND
display. The dynamic guidelines are hidden.
When you change between transmission
positions Dand R, you see the previously
selected front or rear view.
Important safety notes The 360° camera is only an aid. It is not a
replacement for your attention to your
immediate surroundings. You are always
responsible for safe maneuvering and
parking. When maneuvering or parking, make
sure that there are no persons, animals or
objects in the area in which you are
maneuvering.
The 360° camera may show a distorted view
of obstacles, show them incorrectly or not at
all. It cannot show objects in the following
areas:
R
under the front bumper
R very close to the front bumper
R very close to the rear bumper
R under the rear bumper
R in close range above the handle on the
trunk lid
R very close to the exterior mirrors
You are always responsible for safety, and
must always pay attention to your
surroundings when parking and
maneuvering. This applies to the areas
behind, in front of and beside the vehicle. You Driving systems

Important safety notes ATTENTION ASSIST helps you during long,
monotonous journeys, such as on highways.
It is active in the range between 50 mph
(80 km/h) and 112 mph (180 km/h).
If ATTENTION ASSIST detects typical
indicators of fatigue or increasing lapses in
concentration on the part of the driver, it
suggests you take a break.
ATTENTION ASSIST assesses your level of
fatigue or lapses in concentration by taking
the following criteria into account:
R
your personal driving style, e.g. steering
characteristics
R journey details, e.g. time of day and length
of journey
ATTENTION ASSIST is only an aid to the
driver. It might not always recognize fatigue
or increasing inattentiveness in time or fail to
recognize them at all. The system is not a
substitute for a well-rested and attentive
driver.
The functionality of ATTENTION ASSIST is
restricted and warnings may be delayed or
not occur at all:
R if the road condition is poor, e.g. if the
surface is uneven or if there are potholes
R if there is a strong side wind
R if you have adopted a sporty driving style
with high cornering speeds or high rates of
acceleration
R if you are predominantly driving slower
than 50 mph (80 km/h) or faster than
112 mph (180 km/h)
R if you are currently using COMAND or
making a telephone call with it
R if the time has been set incorrectly
R in active driving situations, such as when
you change lanes or change your speed Driving systems
