manoeuvring. This applies to the areas
behind, in front of and next to the vehicle. You
could otherwise endange ryourself and oth-
ers. G
WARNING
Under the following circumstances, the
reversing camera will not function, or will
function in a limited manner:
R if the boot lid/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 light (the dis-
play 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-Benz recommends that you use
a Mercedes-Benz Service Centre for this
purpose.
Do not use the reversing camera in these
types of situation. You could otherwise injure
others or damage objects and your vehicle
while you are parking.
Activating the reversing camera X
Make sure that the key is in position 2in
the ignition lock.
X Make sure that the "Reversing camera"
function is selected in COMAND APS (see
the separate operating instructions for
COMAND APS).
X Engage reverse gear.
The area behind the vehicle is shown in the
COMAND display. ATTENTION ASSIST
Important safety notes ATTENTION ASSIST helps you during long,
monotonous journeys such as on motorways
and trunk roads. It is active in the 80 km/h
to 180 km/h range.
If ATTENTION ASSIST detects typical indica-
tors of fatigue or increasing lapses in con-
centration on the part of the driver, it sug-
gests taking a break.
G
WARNING
ATTENTION ASSIST is only an aid and may
detect your tiredness or lapses in concentra-
tion too late or not at all. It is not asubstitute
for a well rested and attentive driver.
Fatigue may cause you to recognise hazard-
ous situations too late, misjudge a situation
or react slower. For this reason, make sure
you feel rested before you begin driving and
during your journey. Always take breaks in
good time and regularly, especially during
long journeys. Otherwise, you may fail to rec-
ognise dangers in time, cause an acciden tand
injure yoursel fand others.
ATTENTIO NASSIST 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-related parameters, e.g. time of
day, 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 sur-
face is uneven or if there are potholes
R if there is a strong sid ewind
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 80 km/h or faster than 180 km/h Driving systems

Environmental note
Daimler AG also supplies reconditioned
assemblies and parts which are of the same
quality as new parts. For these, the same war-
ranty applies as for new parts.
Always specify the vehicle identification num-
ber (VIN) (Y page 382) and the engine num-
ber (Y page 383) when ordering genuine

ics
G
WARNING
Always have work on the engine electronics
and related components carried out at a quali-
fied specialist workshop. Otherwise, the vehi-
cle's operating safety could be affected.
! Only have work carried out on the engine
electronics and its associated parts, such
as control units, sensors and connector
leads, at a qualified specialist workshop.
Vehicle components may otherwise wear
more quickly and the vehicle's operating
permit may be invalidated. Retrofitting of two-way radios and
mobile phones (RF transmitters)
Use the Technical Specification
ISO/TS 21609 41
implementation regulation
when retrofitting RF (radio frequency) trans-
mitters.
If your vehicle has fittings for two-way radio
equipment, use the power supply or aerial
connections intended for use with the basic
wiring. Be sure to observe the manufacturer's
additional instructions when installing. !
Have aftermarket radio frequency trans-
mitting equipmen tinstalled at a qualified
specialist workshop.
The transmission outpu tatthe aerial base
must not exceed the maximum values below. Waveband Maximum
transmission
output (PEAK) Short wave (f < 54 MHz) 100 W
4 m waveband 30 W
2 m waveband 50 W
trunked radio/Tetra 35 W

GSM/DCS/PCS
850/900/1800/1900 10 W
UMTS/LTE 10 W

WARNING
Incorrect retrofitting of RF transmitters can
cause the vehicle electronics to malfunction.
The vehicle's operating safety and thus your
own safety are impaired.
Have aftermarket radio frequency transmit-
ting equipmen tinstalled at a qualified spe-
cialist workshop. G
WARNING
Incorrect retrofitting of RF transmitters can
lead to increased electromagneti cradiation in
the vehicle interior. Using an exterio raerial
takes into account current scientific discus-
sions relating to the possible health hazards
that may result from electromagnetic fields.
Have aftermarket radio frequency transmit-
ting equipment installed at a qualified spe-
cialist workshop.
Deviations with respect to aerial locations,
output and frequencies must be approved by
Mercedes-Benz. The following can be used in the vehicle with-
out restrictions:
R
RF transmitters with amaximum transmis-
sion output of up to 100 mW
R mobile phones (GSM/DCS/PCS/UMTS/
LTE)
There is no restriction for aerial positions in
the outer area of the vehicle for the following
wavebands:
R trunked radio/Tetra
R 70 cm waveband
R GSM/DCS/PCS
R UMTS/LTE
! The operating permit may be invalidated
if the instructions for installatio nand use of
RF transmitters are not observed, e.g.
approved wavebands, maximu moutput
and aerial positions on the vehicle. Vehicle identification plates
