Warning threshold (in days)
With the HHT it is possible to set a warning threshold of between 5 and 30 days for the remaining time, with a
stepwidth of one day. The basic setting is 30 days.
Display of remaining time
The remaining time is always only displayed in those cases where the following condition is met:
Remaining time (in days) x 40 < remaining distance (in km), and the warning threshold is reached.
The remaining time is displayed in the following cases:
automatically, after 5 s start switch in position 2 or driving, if the warning threshold is reached:
The service symbol and the readout "SERVICE IN ... DAYS" appears for 10 seconds. (On vehicles not
fitted with multifunction display, the current remaining time, the service and the clock symbol appear.)
automatically, after 5 s start switch in position 2 or driving, if the remaining time is exceeded:
The service symbol and the readout "DAYS ... EXCEEDED" appears for 30 s (for 10 s up to mid-July
97). (On vehicles not fitted with multifunction display, the service and the clock symbol appear. The
"remaining time" is displayed with a negative sign (minus sign). The readout flashes in this case.)
After the display reaches the maximum readout of -730 days, the readout remains at this figure! The
readout is displayed with a resolution of 1 day.
As of approx. 06.97 a brief warning signal sounds in addition.
at driver request. The readout is then displayed, as above, for 10 s.
If a speed limit is set at the cruise control, this speed limit is displayed for a short moment before the
ASSYST display.
If certain measured values are not supplied to the ASSYST, e.g. because of failure of a sensor, it switches to
stored substitute values. An appropriate entry is then made in the fault memory of the particular control module.
If the power supply fails, the data are retained. The times without operating voltage (battery disconnected) are
not recorded, however! They can be retroactively included, however, with the HHT.
