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 yourt iredness 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 driving conditions, e.g. time, driving time 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
R if you are currently using COMAND Online
or making a telephone call with it
R if the time has been set incorrectly
R in active driving situations, such as when
you change lanes or change your speed

WARNING
Only have work on the engine electronics and
related components carried out at a qualified
specialist workshop which has the necessary
specialist knowledge and tools to carry out
the work required. Mercedes-Benz recom-
mends that you use a Mercedes-Ben zService
Centre for this purpose. In particular, work
relevant to safety or on safety-related sys-
tems must be carried out at a qualified spe-
cialist workshop. Otherwise, the vehicle's
roadworthiness could be affected.
! Only have maintenance work on the
engine electronics and its associated parts,
such as control units, sensors and connec-
tor leads, carried out at a qualified special-
ist workshop, e.g. a Mercedes-Benz Service
Centre. Vehicle componentsm ay other-
wise 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 22
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 the fit-
tings.
!
Have aftermarket radio frequency trans-
mitting equipmen tinstalled at a qualified
specialist workshop .Mercedes-Benzr ec-
ommends that you use a Mercedes-Benz
Service Centre for this purpose.
The transmission output at the aerial base
must not exceed the maximum values below. Waveband Maximum trans-
mission output

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 equipment installed at a qualified spe-
cialist workshop .Mercedes-Benz recom-
mends that you use a Mercedes-Benz Service
Centre for this purpose. G
WARNING
Incorrect retrofitting 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.
Have aftermarket radio frequency transmit-
ting equipment installed at a qualified spe-
cialist workshop. Mercedes-Benz recom-
mends that you use a Mercedes-Benz Service
Centre for this purpose.
Deviations with respect to aerial locations,
output and frequencies must be approved by
Mercedes-Benz.
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
RF transmitters are not observed, e.g.
approved wavebands, maximum output
and aerial positions on the vehicle. Vehicle identification plates
