Mercedes-Benz C-Class Owners Manual / Maintenance and care / ASSYST PLUS service interval display 

Function of the ASSYST PLUS service interval display

The ASSYST PLUS service interval display on the Instrument Display provides information on the remaining time or distance before the next service due date.

You can hide this service message using the back button on the left-hand side of 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 often left idling for long periods
  • In the event of frequent cold start phases

Mercedes-Benz recommends avoiding such operating conditions.

You can obtain further information concerning the servicing of your vehicle from a qualified specialist workshop, e.g. an authorized Mercedes-Benz Center.

Information on regular maintenance work

NOTE Premature wear through failure to observe service due dates
Service work which is not carried out at the right time or incompletely can lead to increased wear and damage to the vehicle.
  • Always observe the prescribed service intervals.
  • Always have the prescribed service work carried out at a qualified specialist workshop.

Special service requirements

The prescribed service interval is based on normal operation of the vehicle. Maintenance work will need to be performed more often if the vehicle is operated under arduous conditions or increased loads.

The ASSYST PLUS service interval display is only an aid. The driver of the vehicle bears responsibility as regards to whether maintenance work needs to be performed more often than specified based on the actual operating conditions and/or loads.

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 often left 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 filter, engine air cleaner, engine oil and oil filter etc. changed more frequently. The tires must be checked more frequently if the vehicle is operated under increased loads. Further information can be obtained at a qualified specialist workshop.

Battery disconnection periods

The ASSYST PLUS service interval display can only calculate the service due date when the battery is connected.

  • Note down the service due date displayed on the instrument display before disconnecting the battery.
