ASSYST PLUS service interval display

Function of the ASSYST PLUS service interval dis-

play

Always have the prescribed maintenance

work carried out at a qualiﬁed specialist

workshop.

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 back

button G 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:

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 oꢀen than prescri-

bed if operating conditions are diﬃcult 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 oꢀen than prescribed due to actual operat-

ing conditions and/or stresses.

periods

Operation in particularly dusty conditions

and/or if air-recirculation mode is frequently

used

If the Maintenance Management service is activa-

ted, 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 recommendations regarding the maintenance

of your vehicle.

Data transferred when using Maintenance Man-

agement

In these or similar operating conditions, have the

interior air ﬁlter, air ﬁlter, engine oil and oil ﬁlter,

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 qualiﬁed specialist workshop.

When the service is activated, relevant data is

automatically transferred to determine the

required scope of maintenance as well as fault

detection and fault rectiﬁcation.

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://

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 centre via the

maintenance reminder in the multimedia sys-

tem.

Battery disconnection periods

culate the service due date only when the battery

is connected.

The vehicle can detect if certain wear parts need

to 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

entered on the Mercedes me website at: http://

For selected faults, the notiﬁcation that a mal-

function has been detected may appear in the

centre for assistance.

Active bonnet (pedestrian protection)

▌Operation of the active bonnet (pedestrian pro-

tection)

In certain 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 75 mm.

Aꢀer being triggered, the active bonnet remains in

the raised position. Limited visibility due to the

raised bonnet cannot be ruled out.

Data transferred when using Telediagnostics

When the service is activated, relevant data is

automatically transferred to determine the

required scope of maintenance as well as fault

detection and fault rectiﬁcation.

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".

Aꢀer the active bonnet has been actuated, pedes-

trian protection may be limited.

Have the full functionality of the active bonnet

restored immediately in a qualiﬁed specialist

workshop.

If necessary, adjust your seat position and drive

carefully to a qualiﬁed specialist workshop. If a

safe continued journey is not possible, contact a

qualiﬁed specialist workshop.

The transmission of a notiﬁcation to the multi-

vider has no inﬂuence.

Leather is a natural product. It exhibits natural

surface properties such as diﬀerences in

or subtle colour diﬀerences. These surface

properties are characteristics of leather and

not material faults. Leather is also subject to

a natural ageing process during which the sur-

face properties change.

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

reduces soiling, wear marks and ageing dam-

age and thus signiﬁcantly extends its life

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

jeans) may discolour the leather.
