Important safety notes The reversing camera is only an aid. It is not
a replacement for your attention to your
immediate surroundings. You are always
responsible for safe manoeuvring and park-
ing. When manoeuvring or parking, make sure
that there are no persons, animals or objects
in the area in which you are manoeuvring.
Under the following circumstances, the
reversing camera will not function, or will
function in a limited manner:
R the rear door 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 light 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
winter
R if the camera lens is dirty or obstructed
R if the rear of your vehicle is damaged. In
this event, have the camera position and
setting checked at a qualified specialist
workshop. Mercedes-Ben zrecommends
that you use a Mercedes-BenzS ervice
Centre for this purpose. 200

i This Owner's Manual describes all mod-
els, series and optional equipment for your
vehicle that were available at the time of
going to press. Country-specific differen-
ces are possible. Note that your vehicle
may not be fitted with all features descri-
bed. This is also the case for systems and
functions relevant to safety.

ist workshops: (Y page 22). Important safety notes
G
WARNING
Only use the on-board computer when road
and traffic conditions permit .You would oth-
erwise be distracted and unable to concen-
trate properly on driving, and could cause an
accident. G
WARNING
No messages will be displayed if either the
instrument cluster or the multifunction dis-
play is inoperative.
As a result, you will not be able to see infor-
mation about your driving conditions, such as
speed, outside temperature, warning and indi-
cator lamps, display messages or system fail-
ures. Driving characteristics may be impaired.
Adjust your driving style and vehicle speed
accordingly.
Contact a qualified specialist workshop
immediately. G
WARNING
The on-board computer only records and dis-
plays malfunctions and warnings from certain
systems. For this reason, you should always
make sure that your vehicle is safe to use. You
could otherwise cause an accident by driving
an unsafe vehicle. G
WARNING
The operating safety of your vehicle could be
impaired if maintenance work is carried out
incorrectly. This could cause you to lose con-
trol of your vehicle and cause an accident.
Moreover, the safety systems may no longer
be able to protect you or others as they are
designed to do.
Always have service work carried out at a
qualified specialist workshop.
