the boot lid/tail gate 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 APS display.
You can select not to show the area behind
the vehicle in the COMAND APS display (see
the separate operating instructions for
COMAND APS). ATTENTION ASSIST
ATTENTION ASSIST helps you on long, monot-
onous journeys such as on motorways and
trunk roads. It is active at speeds between 80
and 180 km/h. If ATTENTION ASSIST detects tiredness or increasing lapses in concentra-
tion on the part of the driver, it suggests a
break. G
Risk of accident
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 a substitute
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 accident and
injure yourself and others.
ATTENTION ASSIST assesses your level of
fatigue or increasing inattentiveness taking
into consideration the following criteria:
R personal driving style, e.g. steering charac-
teristics
R driving conditions, e. g. time, driving time
ATTENTION ASSIST's functionality is restric-
ted and warnings are delayed or do not
appear at all:
R if the road condition is poor, e.g. large
bumps or potholes
R there is a strong side wind
R you have adopted a very sporty driving style
with high cornering speeds or driving with
a high rate of acceleration
R if you are predominantly driving slower
than 80 km/h or faster than 180 km/h
R if you are currently operating or making a
call using COMAND APS*
R in active driving situations, for example, if
you are changing lanes or changing the
vehicle speed Driving systems

Retrofitting two-way radios and
mobile phones (RF transmitters)
Use the Technical Specification
ISO/TS 21609 46
implementation regulation
when retrofitting RF (radio frequency) trans-
mitters.
If your vehicle has fittings for two-way radio
equipment (e.g. taxis, hire cars or official vehi-
cles), use the power supply or aerial connec-
tions intended for use with the basic wiring.
Be sure to observe the manufacturer's addi-
tional instructions when installing the fittings.
! Damage resulting from installation work
that has not been carried out correctly is
not covered by the Mercedes-Benz implied
warranty.
To ensure correct installation, Mercedes-
Benz recommends having this work done
at a Mercedes-Benz Service Centre or at a
qualified specialist workshop.

not exceed the maximum values below. Waveband Maximum trans-

Risk of accident
Incorrect retrofitting of RF transmitters can
cause the vehicle electronics to malfunction,
impair the vehicle's operating safety and,
thus, also impair your own safety.
To ensure correct installation, Mercedes-
Benz recommends having this work done at a
Mercedes-Benz Service Centre or at a quali-
fied specialist workshop. G
Risk of injury
Improper installation of RF transmitters can
lead to increased electromagnetic radiation in
the vehicle interior. Using an exterior aerial
takes into account current scientific discus-
sions relating to the possible health hazards
that may result from electromagnetic fields.
To ensure correct installation, Mercedes-
Benz recommends having this work done at a
Mercedes-Benz Service Centre or at a quali-
fied specialist workshop.
Deviations with respect to aerial locations,
output and frequencies must be approved by
Mercedes-Benz. Other aerial positions
There is no restriction for aerial positions in
the outer area of the vehicle for these wave-
bands: trunked radio/Tetra, 70 cm wave-
band, GSM 900/AMPS, GSM 1800 and
UMTS.
Legal provisions for fittings must be
observed.
RF transmitters with a maximum transmis-
sion output of 100 mW (PEAK) may be used
in the vehicle without restrictions.
!
The operating permit may be invalidated
if the instructions for installation and use of
