Maintenance Required Lamp/Indicator: Description and Operation

SID 2 and 3 incorporate a service indicator which causes the "TIME FOR SERVICE" message to appear in the SID unit display when the car is due for scheduled service. This is governed by the odometer which tells how many miles the car has covered since the last time it was serviced. The service interval is programmable and programmed at the factory to suit different market requirements. If necessary, the service interval can be changed with the aid of a ISAT Scan Tool.

On model year 1995 and later cars the number of days since the last time the car was service is also counted.

Depending on which occurs first, the service message appears when the day counter reaches 365 days or when only 1,000 km or 600 miles remain until the next scheduled service is due.
