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. This is the
case for frequent operation in mountainous ter-
rain or on poor road surfaces, for example.
In these or similar operating conditions, have the
interior air Nlter changed more frequently. Check
the tyres more frequently if the vehicle is oper-
ated under increased stress. Further information
can be obtained at a qualiNed specialist work-
shop. 398

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 partner that you have entered on the
Mercedes me website at: http:// www.mercedes.me. You will then receive individ-
ual r

ecommendations 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
whether 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
de

tection 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".

nance r

eminder in the multimedia system are
not available in every country. Telediagnostics
Notes about Telediagnostics
%
This service is not available in all countries.
The vehicle can detect if certain wear parts need
t
o be replaced or if malfunctions have occurred in
vehicle systems. If the Telediagnostics service is
activated, 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 Maintenance and care
399

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 AG 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
When the service is activated, relevant data is
aut

omatically transferred to determine the next
required scope of maintenance as well as fault
detection and fault rectiNcation.

cal reasons, not all data is available at all
times. Engine compartment

restored immediately in a qualiNed specialist
workshop.
If necessary, adjust your seat position and drive
carefully to a qualiNed specialist workshop. If a
safe continued journey is not possible, contact a
qualiNed specialist workshop. Notes on the bonnet

cleaning. The water temperature of the high-
pressure cleaner must not exceed 60°C.
= Observe the information on the correct dis-
tance in the equipment manufacturer's opera-
tor manual.
= Do not direct the nozzle of the high-pressure
cleaner directly at sensitive parts, e.g. tyres,
gaps, electrical component parts, batteries,
illuminants and louvres. Washing the vehicle by hand
Observe the relevant legal requirements (e.g. in
some countr
ies, washing by hand is permitted
