gency Call Sy stem Information on
the Emer gency Call Sy stem Yo
ur vehicle is equipped with the Emer gency Call
Sy stem ("eCall"). This feature can help sa velives
in theeve nt of an accident. eCall in no wayre pla‐
ces assis tance pr ovided from dialing 911.
eCall only functions in areas where mobile phone
co verage isavailable from the wireless service
pr ov iders. Insuf ficient network co verage from the
wireless service pr oviders may result in an emer‐
ge ncy call not being transmitted.
eCall is a standard feature in your Mercedes-Benz
ve hicle. In order tofunction as intended, the sys‐
te m relies on the transmission of data de tailed in
th e "Emer gency Call Sy stem data transfer" sec‐
tion that follo ws ( /page 217). Todisable eCall,
a cus tomer must visit an authorized Mercedes-
Benz Service depa rtment todeactivate theve hi‐
cle's communication module.
Deactivation of this module pr events the acti‐
va tion of any and all Mercedes PRO connect
se rvices. Af ter the deacti vation of eCall, auto‐
matic eme rgency call and manual emer gency
call will not be available.
The ignition must be switched on before an auto‐
matic emer gency call can be made.
% eCall is acti
vated at thefa ctor y.
% eCall can be deactivated
byan authorized
Mercedes-Benz dealer. Please no tethat in
th eeve ntow nership of theve hicle is trans‐
fe rred toano ther ow ner in its deacti vated
st ate, eCall will remain deactivated unless
th e new owner visits an au thorized
Mercedes-Benz dealership toreactivate the
sy stem. Emer
gency Call Sy stem eCall can help
toreduce the time between an
accident and the ar riva l of emer gency services at
th e site of the accident. It helps locate an acci‐
dent site in places that are dif ficult toaccess.
Ho wever,eve n if a vehicle is equipped with eCall,
th is does not mean the sy stem is ON. As such,
eCall does not replace dialing 911 in theeve nt of
an accident.
The emergency call can be made au tomatical ly
( / page 217) or manually (/ page217). Only
make emergency calls if you or others are in need
of rescue. Do not make an emer gency call in the
