General notes ATTENTION ASSIST helps you during long,
monotonous journeys such as on motorways
and trunk roads. It is active in the 60 km/h to
200 km/h speed range. If ATTENTION ASSIST detects typical indicators of fatigue or increas-
ing lapses in concentration on the part of the
driver, it suggests taking a break.
Important safety notes ATTENTION ASSIST is only an aid. It may not
always detect fatigue or lapses in concentration
until too late, or may not detect them at all. The system is not a substitute for a well-rested and
attentive driver.
The functionality of ATTENTION ASSIST is
restricted, and warnings may be delayed or not
occur at all:
R if the length of the journey is less than approx-
imately 30 minutes
R if the road condition is poor, e.g. if the surface
is uneven or if there are potholes
R if there is a strong side wind
R if you have adopted a sporty driving style with
high cornering speeds or high rates of accel-
eration
R if you are predominantly driving at a speed
below 60 km/h or above 200 km/h
R if the time has been set incorrectly
R in active driving situations, such as when you
change lanes or change your speed
ATTENTION ASSIST is reset and starts assessing
your tiredness again when you continue your
journey if:
R you switch off the engine
R you take off your seat belt and open the driv-
er's door, e.g. for a change of drivers or to
take a break
Displaying the attention level You can have current status information dis-
played in the assistance menu (Y

Approved aerial positions
:
Front roof area
; Rear roof area
= Rear wing
i On the rear wing, it is recommended that
you position the aerial on the side of the vehi-
cle closest to the centre of the road.
Use Technical Specification ISO/TS 21609
(Road Vehicles – "EMC guidelines for fitting
aftermarket radio frequency transmitting equip- ment") when retrofitting RF (radio frequency)
transmitters. Comply with the legal require-
ments for add-on parts.
If your vehicle has fittings for two-way radio
equipment, use the power supply or aerial con-
nections intended for use with the basic wiring.
Be sure to observe the manufacturer's addi-
tional instructions when installing.
Deviations with respect to wavebands, maxi-
mum transmission outputs or aerial positions
must be approved by Mercedes-Benz.
The maximum transmission output (PEAK) at the base of the aerial must not exceed the followingvalues: Waveband Maximum
transmission output Short wave
3 - 54 MHz 100 W
4 m waveband
74 - 88 MHz 30 W
2 m waveband
144 - 174 MHz 50 W
Trunked radio/Tetra
380 - 460 MHz 10 W Waveband Maximum
transmission output 70 cm waveband
400 - 460 MHz 35 W
Mobile communications
(2G/3G/4G) 10 W
The following can be used in the vehicle without
restrictions:
R RF transmitters with a maximum transmis-
sion output of up to 100 mW
R RF transmitters with transmitter frequencies
in the 380 - 410 MHz waveband and a maxi-
mum transmission output of up to 2 W
(trunked radio/Tetra)
R Mobile telephones (2G/3G/4G)
There are no restrictions when positioning the
aerial on the outside of the vehicle for the fol-
lowing wavebands:
R Trunked radio/Tetra
R 70 cm waveband
