R
pay attention to the PARKTRONIC
(Y page 157) warning messages during the
parking procedure
R you can intervene in the steering procedure to
correct it at any time. Active Parking Assist
will then be cancelled
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 fitted
R make sure that the tyre pressures are always
correct. This has a direct influence on the
parking characteristics of the vehicle.
Use Active Parking Assist for parking spaces
that are:
R parallel to the direction of travel.
R on straight roads, not bends
R 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 cal- culated, e.g. overhanging loads, tail sections or
loading ramps of goods vehicles. G
WARNING
If there are objects above the detection range:
R Active Park Assist may steer too early
R the vehicle may not stop in front of these
objects
This could cause a collision. There is a risk of
an accident.
If objects are located above the detection
range, stop and deactivate Active Parking
Assist.
For further information on the detection range
(Y page 156).
Active Parking Assist does not support you park-
ing in spaces that are parallel to the direction of
travel if:
R the parking space is on a kerb
R the parking space appears to be blocked, for
example by foliage or grass paving blocks R
the range of movement is too small
R the parking space is bordered by an obstacle
which is not clearly defined such as a tree or a
trailer Example: parking symbol
:
Detected parking space on the left
; Parking symbol
= Detected parking space on the right
Active Parking Assist is activated automatically
when driving forwards. The system is opera-
tional at speeds of up to approximately
35 km/ h.While in operation, the system inde-
pendently locates and measures parking spaces on both sides of the vehicle.
Active Parking Assist will only detect parking
spaces:
R parallel to the direction of travel
R that are at least 1.5 m wide
R that are at least 1.3 mlonger than your vehicle
When driving at speeds below 30 km/h, you will
see parking symbol ;as a status indicator in
the instrument cluster. When a parking space
has been detected, an arrow towards the right or the left also appears. Active Parking Assist only
displays parking spaces on the front-passenger side as standard. Parking spaces on the driver's
side are displayed as soon as the turn signal on the driver's side is activated. When parking on
the driver's side, this must remain activated
until you confirm the use of Active Parking Assist
by pressing the abutton on the multifunc-
tion steering wheel.
A parking space is displayed while you are driv- ing past it, and until you are approximately 15 maway from it.

WARNING
Active Parking Assist merely aids you by inter- vening actively in the steering. There is a risk
of accident if you do not apply the brakes
yourself. Driving systems

Reversing camera
General notes Reversing camera
:is an optical parking and
manoeuvring aid. It uses guide lines to show the
area behind your vehicle in the Audio/COMAND
display.
The area behind the vehicle is displayed as a
mirror image, as in the rear-view mirror.
i The text shown in the Audio/COMAND dis-
play depends on the language setting. The
following are examples of reversing camera
displays in the Audio/COMAND display.
See the notes on cleaning (Y page 246).
Important safety notes The reversing camera is only an aid. It is not a
substitute for your attention to the immediate
surroundings. The responsibility for safe
manoeuvring and parking remains with you.
Make sure that there are no persons, animals or
objects in range while manoeuvring and parking.
Under the following circumstances, the revers-
ing camera will not function, or will function in a limited manner:
R if the tailgate is open
R in heavy rain, snow or fog
R at night or in very dark places
R if the camera is exposed to very bright light
R if the area is lit by fluorescent bulbs or LED
lighting (the display may flicker)
R if there is a sudden change in temperature,
e.g. when driving into a heated garage in win-
ter R
if the camera lens is dirty or obstructed.
Observe the notes on cleaning
(Y page 246)
R if the rear of your vehicle is damaged. In this
case, have the camera position and setting
checked at a qualified specialist workshop.
The field of vision and other functions of the
reversing camera may be restricted due to addi-
tional accessories on the rear of the vehicle (e.g. licence plate holder, bicycle rack).
Activating/deactivating the reversing
camera X

guide lines in the Audio 20/COMAND Online
display.
The image from the reversing camera is avail-
able throughout the manoeuvring process.
To deactivate: the reversing camera deacti-
vates if you shift the transmission to Por after
driving forwards a short distance.
Displays in the Audio 20/COMAND dis-
play The reversing camera may show a distorted view
of obstacles or show them incorrectly or not at
all. Obstacles are not shown by the reversing
camera in the following locations:
R very close to the rear bumper
R under the rear bumper
R in the area immediately above the tailgate
handle
! Objects not at ground level may appear to
be further away than they actually are, e.g.:
R the bumper of a parked vehicle
R the drawbar of a trailer
R the ball coupling of a trailer tow hitch
R the rear section of an HGV
R a slanted post
Use the guidelines only for orientation.
Approach objects no further than the bottom- most guideline. 162

WARNING
Operating the integrated information systems and communications equipment in the vehicle
while driving will distract you from traffic con-
ditions. You could then lose control of the
vehicle. There is a risk of an accident.
Only operate these devices if road traffic con-
ditions permit. If you are unsure about the
surrounding conditions, pull over to a safe
location and make entries only while the vehi-
cle is stationary.
You must observe the legal requirements for the country in which you are currently driving whenoperating the on-board computer. G
WARNING
If the instrument cluster has failed or mal-
functioned, you may not recognise function
restrictions relevant to safety. The operating
safety of your vehicle may be impaired. There is a risk of an accident.
Drive on carefully. Have the vehicle checked
at a qualified specialist workshop immedi-
ately.
The on-board computer only shows messages or warnings from certain systems in the multifunc-tion display. You should therefore make sure
your vehicle is operating safely at all times.
If the operating safety of your vehicle is
impaired, park the vehicle safely as soon as pos- sible. Contact a qualified specialist workshop. For an overview, see the instrument panel illus-
tration (Y page 27). Displays and operation
