ASSYST PLUS service interval display
Function of the ASSYST PLUS service interval dis-
play
The ASSYST PLUS service interval display on the driver\bs display provides information on the
remaining time or distance before the next
service due date.
You can hide this service display using the G
back button on the steering wheel.
Depending on how the vehicle is used, the
ASSYST PLUS service interval display may shorten
the service interval, e.g. in the following cases:
= Mainly short-distance driving
= When the engine is o"sen le"s idling for long
periods
= In the event of frequent cold start phases
Mercedes-Benz recommends avoiding such oper-
ating conditions.
You can obtain information concerning the servic- ing of your vehicle from a quali"Ned specialist
workshop, e.g. an authorized Mercedes-Benz Cen-
ter.
Displaying the service due date
Driver\bs display:

Information on regular maintenance work
*NOTE Premature wear through failure to
observe service due dates
Maintenance work which is not carried out at
the right time or incompletely can lead to
increased wear and damage to the vehicle.
Adhere to the prescribed service inter- vals.Always have the prescribed maintenance
work carried out at a quali"Ned specialist
workshop.Notes on special service requirements
The prescribed service interval is based on nor-
mal operation of the vehicle. Have the mainte-
nance work carried out more o"sen than prescri-
bed if operating conditions are di"Pcult 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 o"sen 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
= Frequent operation in mountainous terrain or
on poor road surfaces
= When the engine is o"sen le"s idling for long
periods
= Operation in particularly dusty conditions
and/or if air-recirculation mode is frequently
used
370Maintenance and care

In these or similar operating conditions, have theinterior air "Nlter, air "Nlter, engine oil and oil "Nlter,
for example, changed more frequently. If subject
to increased stress, check the tires more. Further
information can be obtained at a quali"Ned special-
ist workshop.
Battery disconnection periods
The ASSYST PLUS service interval display can cal- culate the service due date only when the batteryis connected.
Display and note down the service due date
on the driver\bs display before disconnecting
the battery (  page 370).
Maintenance Management
Notes about Maintenance Management
If the Maintenance Management service is activa-
ted, relevant data is automatically transferred to
the Mercedes-Benz customer center.
The customer center 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 recommendations regarding the maintenance of your vehicle.\bThe calculation of the optimal transmission
time of the 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 center via the
maintenance reminder in the multimedia sys-
tem.\bMaintenance Management and the mainte-
nance reminder in the multimedia system are not available in every country. Contact an
authorized Mercedes-Benz Center to "Nnd out
whether this function is available in your coun-
try.Data transferred when using Maintenance Man-
agement
When the service is activated, relevant data is
automatically transferred to determine the
required scope of maintenance as well as mal-
function detection and malfunction recti"Ncation.
Details on data transfer can be found in the data protection information for the Mercedes me con-
nect services. These can be found at: https://
www.mercedes.me under "My Mercedes me
account", "Terms of use".
\bMaintenance Management and the mainte-
nance reminder in the multimedia system are not available in every country.
Telediagnosis
Notes about Telediagnosis
\bThis service is not available in all countries.
The vehicle can detect if certain wear parts need
to be replaced or if malfunctions have occurred in
vehicle systems. If the Telediagnosis service is activated, relevant data is automatically transmit-
ted to the manufacturer. If fault conditions are

detected by the vehicle system self-diagnosis, thesystem transmits recommendations for action to
the Mercedes-Benz customer center depending on the fault detected. The customer center trans-mits the data to the service partner that you haveentered on the Mercedes me website at: http://www.mercedes.me.
For selected faults, the noti"Ncation that a mal-
function has been detected may appear in the multimedia system with a request to contact the
Mercedes-Benz customer center. From this mes- sage, a call can be made directly to the customer
center for assistance.\bThe transmission of a noti"Ncation 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 in"Ouence.\bReliable fault detection is subject to technical
limitations. Therefore, only a limited selection
of faults can be detected and recommenda- tions for action transmitted to the customer
center and the service partners. Mercedes- Benz AG is continuously working on theexpansion of this service. The fault detectiondepends on the country, vehicle model andequipment.
