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.
R Snowfall or heavy rain may lead to a parking
space being measured inaccurately.
R Pay attention to the PARKTRONIC
(Y page 219) warning messages during the
parking procedure.
R When transporting a load which protrudes
from your vehicle, you should not use
Active Parking Assist.
R Never use Active Parking Assist when snow
chains are installed.
R Make sure that the tire pressures are
always correct. This has adirec tinfluence
on the parking characteristics of the
vehicle.
General notes Active Parking Assist is an electronic parking
aid with ultrasound. Ultrasound is used to
measure the road on both sides of the vehicle.
As
uitable parking space is indicated by the
parking symbol. Active steering intervention
can assis tyou during parking.
You may also use PARKTRONIC
(Y page 217). When PARKTRONIC is switched
off, Active Parking Assist is also unavailable.
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
Detecting parking spaces 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.
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. In some circumstances, Active
Parking Assist may therefore guide you into
the parking space too early. 0002
Detected parking space on the left
0003 Parking symbol
0021 Detected parking space on the right
Active Parking Assist is switched on
automatically when driving forwards. The
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. When driving at speeds below
19 mph (30 km/h), you will see the parking
symbol as a status indicator in the instrument
cluster. By default, Active Parking Assist only
displays parking spaces on the front-
passenger side. Parking spaces on the
driver's side are displayed as soon as the turn
signal on the driver's side is activated. To park
on the driver's side, you must leave the
driver's side turn signal switched on. This
must remain switched on until you
acknowledge the use of Active Parking Assist
by pressing the 000Bbutton on the
multifunction steering wheel.
When a parking space has been detected, an
arrow towards the right or the left also
appears. 222

Ap arking space is displayed while you are
driving past it, and until you are
approximately 50 ft (15 m) away from it.

positio nand shape of the vehicles parked
in front and behind it and the conditions of
the location. It may be the case tha tActive
Parking Assist guides you too far into a Driving systems

parking space, or not far enough into it. In
some cases, it may also lead you across or
onto the curb. If necessary, you should
cancel the parking procedure with Active
Parking Assist.

prematurely. The vehicle redirects and
does not drive as far into the parking space.

to correct it at any time. Active Parking
Assist will then be canceled.

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
could otherwise endanger yourself and
others.
The rear view camera will not function or will

to objects or the vehicle. 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-scree nviews are:
R top view and picture from the rear view

R top view and picture from the front camera
(withou tdisplaying the maximum steering
wheel angle)

Important safety notes 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.
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
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

board computer (Y page 277).
Symbol 0002appears in the multifunction
display.
X The Attention Assist: Take a Break! message appears in the

If ATTENTION ASSIST is active, you will be
warned no sooner than 20 minutes after your
journey has begun. In addition to the message
shown in the multifunction display, you will
then hear an intermittent warning tone twice.
On long journeys, take regular breaks in good
time to allow yourself to rest properly. If you
do not take a break and ATTENTION ASSIST
still detects increasing lapses in
concentration, you will be warned again after
15 minutes at the earliest. 234
