NOTE Pr
emature wear through failure to
observe service due dates Maintenance work which is not carried out at
t
he right time or incompletely can lead to
increased wear and damage to the vehicle. 
Adhere to the prescribed service inter-
v
als. 
Always have the prescribed maintenance
w

ork carried out at a qualiNed specialist
workshop. Notes on special service requirements
The prescribed service interval is based on nor-
mal oper

ation of the vehicle. Have the mainte-
nance work carried out more osen than prescri-
bed if operating conditions are diPcult or the
vehicle is subject to increased stress.
The ASSYST PLUS service interval display is only
an aid. It is the responsibility of the driver of the
vehicle to have maintenance work carried out
more osen than prescribed due to actual operat-
ing conditions and/or stresses.
Examples of arduous operating conditions:
= Regular city driving with frequent intermediate
stops
= Mainly short-distance driving Maintenance and care

=
F requent operation in mountainous terrain or
on poor road surfaces
= When the engine is osen les idling for long
periods
= Operation in particularly dusty conditions
and/or if air-recirculation mode is frequently
used
In these or similar operating conditions, have the
interior air Nlter, air Nlter, engine oil and oil Nlter,
for example, changed more frequently. Check the
tyres more frequently if the vehicle is operated
under increased stress. Further information can
be obtained at a qualiNed specialist workshop. Battery disconnection periods
The ASSYST PLUS service interval display can cal-
culat
e the service due date only when the battery
is connected. 
Display and note down the service due date
on t

he instrument display before disconnect-
ing the battery ( page 335). Maintenance Management
Notes about Maintenance Management
If the Maintenance Management service is activa-
t

ed, relevant data is automatically transferred to
the Mercedes-Benz customer centre.
The customer centre transmits the data to the
service partners that you have entered on the
Mercedes me website at: http://
www.mercedes.me. You will then receive individ-
ual recommendations regarding the maintenance
of your vehicle.
% The calculation of the optimal transmission
time of t

he maintenance request to the
service partner is subject to technical limita-
tions that may cause the maintenance recom-
mendation to be perceived as too early or too
late or not to be made at all. In this case, you
can conveniently arrange a maintenance
appointment with the customer centre via the
maintenance reminder in the multimedia sys-
tem.
% Maintenance Management and the mainte-
nance r

eminder in the multimedia system are
not available in every country. Contact a Mercedes-Benz service centre to Nnd
out
whe
ther this function is available in your coun-
try. Data transferred when using Maintenance Man-
ag

ement When the service is activated, relevant data is
aut

omatically transferred to determine the
required scope of maintenance as well as fault
detection and fault rectiNcation. Details on data
transfer can be found in the data protection infor-
mation for the Mercedes me connect services.
These can be found at: http://www.mercedes.me
under "My Mercedes me account", "Terms of use".

stem is not available in all countries. Telediagnostics

vehicle systems. If the Telediagnostics service is
activ ated, relevant data is automatically transmit-
ted to the manufacturer. If fault conditions are
detected by the vehicle system self-diagnosis, the
system transmits recommendations for action to
the Mercedes-Benz customer centre depending
on the fault detected. The customer centre trans-
mits the data to the service partner that you have
entered on the Mercedes me website at: http://
www.mercedes.me.
For selected faults, the notiNcation that a mal-
function has been detected may appear in the
multimedia system with a request to contact the
Mercedes-Benz Customer Centre. From this mes-
sage, a call can be made directly to the customer
centre for assistance.
% The transmission of a no
tiNcation to the multi-
media system depends on the country, vehi-
cle model and equipment and requires a fast
data connection, over which the service pro-
vider has no inOuence.
% Reliable fault detection is subject to technical
limit
ations. Therefore, only a limited selection
of faults can be detected and recommenda-
tions for action transmitted to the customer centre and the service partners. Mercedes-
Benz A
G is continuously working on the
expansion of this service. The fault detection
depends on the country, vehicle model and
equipment. Data transferred when using Telediagnostics

nect services. These can be found at: http://

Active bonnet (pedestrian protection)
Operation of the active bonnet (pedestrian protec-
tion)
In cer

tain accident situations, the actuation of the
active bonnet reduces the risk of injury to pedes-
trians. The rear area of the bonnet is raised by
approximately 70 mm.
For the drive to the workshop, reset the actuated
active bonnet yourself (  page 337).
Aser the active bonnet has been actuated, pedes-
trian protection may be limited.
Have the full functionality of the active bonnet
restored in a qualiNed specialist workshop.
