Trailer tow hitch
!Retrofitting a trailer tow hitch is not per-
missible.
Warning
Vehicles with an electric motor generate
much less driving noise than vehicles with
internal combustion engines. As a result, your
vehicle may not be heard by other road users
until it is very close to them, or it may not be
heard at all. This is particularly the case if
other road users have not yet seen your vehi-
cle but are instead relying on hearing. Drive
with particular care, allowing for the possibil-
ity that other road users may behave unpre-
dictably.
The vehicle is equipped with a sound gener-
ator. The sound generator is activated so that
other road users can hear your vehicle better.
The sound generator is activated at speeds of
under 20 mph (30 km/h) and switches off
automatically at higher speeds.
Declarations of conformity
Vehicle components which receive
and/or transmit radio waves
USA: "The wireless devices of this vehicle
comply with Part 15 of the FCC Rules. Oper-
ation is subject to the following two condi-
tions: 1) These devices may not cause harm-
ful interference, and 2) These devices must
accept any interference received, including
interference that may cause undesired oper-
ation. Changes or modifications not expressly
approved by the party responsible for com- pliance could void the user’s authority to
operate the equipment."
Canada:
"The wireless devices of this vehicle
comply with Industry Canada license-exempt RSS standard(s). Operation is subject to the
following two conditions: (1) These devices
may not cause interference, and (2) These
devices must accept any interference, includ-
ing interference that may cause undesired
operation of the device."
Diagnostics connection
The diagnostics connection is only intended
for the connection of diagnostic equipment at
a qualified specialist workshop.
GWARNING
If you connect equipment to the diagnostics
connection in the vehicle, it may affect the
operation of the vehicle systems. As a result,
the operating safety of the vehicle could be
affected. There is a risk of an accident.
Do not connect any equipment to a diagnos-
tics connection in the vehicle.
GWARNING
Objects in the driver's footwell can restrict the pedal travel or obstruct a depressed pedal.
The operating and road safety of the vehicle is
jeopardized. There is a risk of an accident.
Make sure that all objects in the vehicle are
stowed correctly, and that they cannot enter
the driver's footwell. Install the floormats
securely and as specified in order to ensure
sufficient clearance for the pedals. Do not use
loose floormats and do not place floormats on
top of one another.
!If equipment on the diagnostics connec-
tion is used, the starter battery may dis-
charge.

Useful information
i
This Operator's Manual describes all
models and all standard and optional equip-
ment of your vehicle available at the time of
publication of the Operator's Manual.
Country-specific differences are possible.
Please note that your vehicle may not be
equipped with all features described. This
also applies to safety-related systems and
functions.
iRead the information on qualified special-
ist workshops (
Ypage 26).
Information regarding technical data
i
The data stated here specifically refers to
a vehicle with standard equipment. Consult an authorized Mercedes-Benz Center for
the data for all vehicle variants and trim
levels.
Vehicle electronics
Retrofitting two-way radios and
mobile phones (RF transmitters)
GWARNING
The electromagnetic radiation from modified
or incorrectly retrofitted RF-transmitters can
interfere with the vehicle electronics. This can compromise the operational safety of the
vehicle. There is a risk of an accident.
You should have all work to electrical and
electronic equipment carried out at a qualified
specialist workshop.
GWARNING
The electromagnetic radiation from incor-
rectly operated RF transmitters can interfere
with the vehicle electronics, for example:
Rif the RF transmitter is not connected with
an exterior antenna
Rthe exterior antenna has been installed
incorrectly or is not a low-reflection type
This can compromise the operational safety
of the vehicle. There is a risk of an accident.
Have the low-reflection exterior antenna
mounted at a qualified specialist workshop.
When operating RF transmitters in the vehi-
cle, always connect them with the low-reflec-
tion exterior antenna.
!The operating permit may be invalidated if
the instructions for installation and use of
RF transmitters are not observed.
In particular, the following conditions must
be complied with:
Ronly approved wavebands may be used.
Rcompliance with the maximum permissi-
ble output in these wavebands is
required.
Ronly approved antenna positions may be used.
Excessive levels of electromagnetic radiation
may cause damage to your health and the
health of others. Using an exterior antenna
takes into account current scientific discus-
sions relating to the possible health hazards
that may result from electromagnetic fields.

Approved antenna positions
:
Front roof area
;Rear roof area
=Rear fender
iOn the rear fenders, it is recommended to
position the antenna on the side of the
vehicle closest to the center of the road.
Use the Technical Specification ISO/TS
21609 when retrofitting RF transmitters
(Road Vehicles - EMC guidelines for installa-
tion of aftermarket radio frequency transmit-
ting equipment). Observe the legal require-
ments for retrofittings.
If your vehicle has installations for two-way
radio equipment, use the power supply or
antenna connections intended for use with
the basic wiring. Be sure to observe the man- ufacturer's additional instructions when
installing.
Deviations with respect to wavebands, maxi-
mum transmission outputs or antenna posi-
tions must be approved by Mercedes-Benz.
The maximum transmission output (PEAK) at
the base of the antenna must not exceed the
following values:
WavebandMaximum
transmission output
Short wave
3 - 54 MHz100 W
4 m waveband
74 - 88 MHz30 W

400 - 460 MHz35 W
Mobile communications
(2G/3G/4G)10 W
The following can be used in the vehicle with-
out restrictions:
RRF transmitters with a maximum transmis-
sion output of up to 100 mW
RRF transmitters with transmitter frequen-
cies in the 380 - 410 MHz waveband and a
maximum transmission output of up to 2 W
(trunked radio/Tetra)
RMobile telephones (2G/3G/4G)
There is no restriction for antenna positions
on the outside of the vehicle for the following
wavebands:
