ASSYST PLUS service interval display

Function of the ASSYST PLUS service interval dis-

play

The ASSYST PLUS service interval display on the

driver's 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en le 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ed specialist

workshop, e.g. an authorized Mercedes-Benz Cen-

ter.

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ed 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en than prescri-

bed if operating conditions are dicult 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en 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en le idling for long

periods

Operation in particularly dusty conditions

and/or if air-recirculation mode is frequently

used

Maintenance and care

273

In these or similar operating conditions, have the

interior air lter, air lter, engine oil and oil lter,

for example, changed more frequently. If subject

to increased stress, check the tires more. Further

information can be obtained at a qualied special-

ist workshop.

Battery disconnection periods

The ASSYST PLUS service interval display can cal-

culate the service due date only when the battery

is connected.

Display and note down the service due date

on the driver display before disconnecting the

battery (/ page 273).

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:

www.. You will then receive individ-

ual recommendations regarding the maintenance

of your vehicle.

The 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.

Maintenance Management and the mainte-

nance reminder in the multimedia system are

not available in every country. Contact an

authorized Mercedes-Benz Center to nd 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cation.

Details on data transfer can be found in the data

protection information for the Mercedes me con-

nect services. These can be found at:

www. under "My Mercedes me

account", "Terms of use".

Maintenance Management and the mainte-

nance reminder in the multimedia system are

not available in every country.

Telediagnosis

Notes about Telediagnosis

This 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-

Maintenance and care

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 center depending

on the fault detected. The customer center trans-

mits the data to the service partner that you have

entered on the Mercedes me website at:

www..

For selected faults, the notication 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.

The transmission of a notication 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uence.

Reliable 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 the

expansion of this service. The fault detection

depends on the country, vehicle model and

equipment.

Data transferred when using Telediagnostics

Waves or wrinkling in the seat cover may

occur due to the stress on the seat; this is

caused by the natural leather material.

Regular cleaning and care of the leather

span. Clothing that can leave stains (e.g.

jeans) may discolor the leather.
