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 now The letter indicates how much time the work-
shop will require to carry out the service work.
The letters displayed range from
Afor a short
service duration to Hfor a long service dura-
tion.

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
