Diagnostics connection
The diagnostics connection is only intended for
the connection of diagnostic equipment at a
qualified specialist workshop. G
WARNING
If you connect equipment to a diagnostics
connection in the vehicle, it may affect the
operation of vehicle systems. As a result, the operating safety of the vehicle could be affec-
ted. There is a risk of an accident.
Only connect equipment to a diagnostics con-
nection in the vehicle, which is approved for
your vehicle by Mercedes-Benz. G
WARNING
Objects in the driver's footwell may restrict
the clearance around the pedals or block a
depressed pedal. This jeopardises the oper-
ating and road safety of the vehicle. There is a risk of an accident.
Stow all objects securely in the vehicle so that
they do not get into the driver's footwell.
Always fit the floormats securely and as pre-
scribed in order to ensure that there is always sufficient room for the pedals. Do not use
loose floormats and do not place several floor- mats on top of one another.
! If the engine is switched off and equipment
on the diagnostics connection is used, the
starter battery may discharge.
Connecting equipment to the diagnostics con-
nection can lead to emissions monitoring infor-
mation being reset, for example. This may lead
to the vehicle failing to meet the requirements of the next emissions test during the main inspec-
tion. Qualified specialist workshop
A qualified specialist workshop has the neces-
sary special skills, tools and qualifications to
correctly carry out any necessary work on your
vehicle. This particularly applies to work rele-
vant to safety.
Observe the notes in the Service Booklet.
Always have the following work carried out at a
qualified specialist workshop:
R work relevant to safety
R service and maintenance work
R repair work
R modifications, installations and conversions
R work on electronic components
Mercedes-Benz recommends that you use a
Mercedes-Benz Service Centre. Vehicle registration
Mercedes-Benz may ask its Service Centres to
carry out technical inspections on certain vehi-
cles. The quality or safety of the vehicle is
improved as a result of the inspection.
Mercedes-Benz can only inform you about vehi-
cle checks if it has your registration data.
It is possible that your vehicle has not yet been
registered in your name in the following cases:
R if your vehicle was not purchased at an
authorised specialist dealer.
R if your vehicle has not yet been examined at a
Mercedes-Benz Service Centre.
It is advisable to register your vehicle with a
Mercedes-Benz Service Centre. Operating safety
27Introduction Z

When Active Parking Assist is cancelled, you
must steer again yourself. Reversing camera
General notes Reversing camera
:is an optical parking and
manoeuvring aid. It shows the area behind your vehicle with guide lines in the multimedia sys-
tem.
The area behind the vehicle is displayed as a
mirror image, as in the rear-view mirror.
i The text shown in the multimedia system
display depends on the language setting. The following are examples of reversing camera
messages in the multimedia system.
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 boot lid 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 285)
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).
For technical reasons, leaving the standard
height can result in inaccuracies in the guide
lines on vehicles with a height-adjustable chas-
sis.
Activating/deactivating the reversing
camera X
To activate: make sure that the key is in
position 2in the ignition lock.
X Make sure that the Activation by R gear Activation by R gear
function is selected in the multimedia system; see the Digital Owner's Manual.
X Engage reverse gear.
The multimedia system shows the area
behind the vehicle with guide lines.
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 multimedia system 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 handle on
the boot lid
! 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 Driving systems
