ASSYST PLUS service interval display

ASSYST PLUS, the service interval display, tells you when the next service is due. Whenever a service is due, the following message appears in the multi-function display:

Service A due in .. days

Service A due in .. km

Service A due now

The letter indicates how much time the workshop will require to carry out the service work. The letters displayed range from A for a short service duration to H for a long service duration.

The service interval display ASSYST PLUS does not record any periods of time during which the battery is disconnected. In order to maintain the time-dependent service schedule, you should call up the service due date and make a note of it before disconnecting the battery. The alternative is to subtract the battery disconnection periods from the service date shown on the display.

Exceeding the service due date

A qualified specialist workshop, e.g. a Mercedes-Benz Service Centre, will reset the ASSYST PLUS service interval indicator after the necessary service work has been carried out.
