Service
ASSYST PLUS service interval display
ASSYST PLUS, the service interval display,
tells you when the next service is due. When-
ever 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
1 into
The letter indicates how much time the work-
shop 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 dura-
tion.
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 sched-
ule, 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.
