Technical features of dash panel insert
The dash panel insert is equipped with a service interval extension facility. The dash panel insert evaluates the
service requirement for the vehicle concerned on the basis of various input variables, such as driving style or
oil consumption.
The conventional service indicator (with fixed intervals) indicated a due service at 15000 km or 12 months.
By means of suitable limit value programming, the service interval extension function is capable of simulating
the behaviour of the conventional service display.
For this purpose, the limit values are designed to be flexible.
Provision is also made for evaluation of the oil temperature sender. The service indication can then be displayed
later (max. 30000 km or 730 days) by means of appropriate adaption channels in the self-diagnostic function.
Two different dash panel inserts are fitted:
◆ Midline: With Minicheck system
◆ Highline: With driver information system (DIS)
The speedometer features a mileage counter and trip recorder LCD.
The rev counter features a clock/date LCD.
The warning lamps are integrated into the speedometer and rev counter.
The centre display presents a selection menu and the service indicator.
The menu is controlled from a function selector switch in the centre console.

be determined using the vehicle diagnostic, testing and information system VAS 5051.
