The remaining distance is displayed with a resolution of 100 km.
If a speed limit is set at the cruise control, the speed limit appears for a short moment in the display before
the ASSYST text.
In the normal case, it is the remaining distance which is displayed. However, the time information is always
processed in the background to enable the attention of "low-mileage drivers" to be drawn to any service due.
The remaining distance is compared each day with the remaining time. In certain circumstances, the display
switches over, and it is the remaining time which is displayed ( see document "Remaining time").
If certain measured values are not supplied to the ASSYST system, e.g. because of failure of a sensor, it
switches over to stored substitute values. A corresponding entry is made in the fault memory of the relevant
control module.
The data are retained if the operating voltage is disconnected or fails.

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.

Fig. 1: Identifying Electronic Accelerator Function

The function of the electronic accelerator pedal EFP in the ME control unit determines the opening angle of the
throttle valve over the actuator EFP/TPM/LLR (other designation: throttle valve actuator).
Further functions are:
Idle speed control [ISC]
Cruise control mode
Variable speed limiter
30 km/hour limit
Reduce/increase the engine torque for ASR/ESP operation
short performance limitation, for example for a higher coolant temperature
Emergency electronic accelerator pedal
Safety concept
Actuate indicator lamp EPC (up to 5/96)
Storing faults
Data exchanger via CAN

The opening angle of the throttle valve will only be determined by the accelerator pedal specification when no
limiting functions are active.
The accelerator pedal position is detected by the set value potentiometer (B37r1) or Hall sensor in the pedal
value sensor (B37) and information is released to the ME control unit (N3/10). In this way, the ME-SFI control
unit determines the position of the throttle valve and actuates the throttle valve motor (M16/1 m1).
The actual value potentiometer in the actuator (M16/1r1) signals the throttle valve position back to the ME-SFI
control unit.
The second potentiometer in the actuator (M16/1 r2) and the second signal from the pedal value sensor
(potentiometer or Hall sensor) supplies a reference value for the plausibility check. In addition, the system
switches over to the second potentiometer or the Hall sensor if the first potentiometer or Hall sensor fails
(emergency mode).
Adaptive accelerator pedal (model 203, 209, 211, 215, 220, 230):
The engine control unit recognizes how the accelerator pedal is being actuated and switches between
characteristic curves. Eighty percent of the engine load is released for a pedal travel of about 50 % for a sporty
driver and about 40 % for a quiet driver. There is no further difference felt above a pedal travel of about 90 %.

If, for example, the characteristic curve for a quiet driver is active after a long drive on the motorway then the
accelerator pedal must be pressed down unusually hard to obtain a higher acceleration level.
Kickdown switch (S16/6)
The kickdown switch was no longer used from 9/01. Recognition of full load is now achieved over the signal
from the pedal value sensor. The pressure point on the accelerator pedal before achieving the full load position
remains.

Task
Optimizing driving comfort and safety when reversing.
Design/function
The pedal value sensor characteristic curve is changed if reverse travel is recognized by the ME control unit.
The throttle valve opens more slowly. The entire opening angle in this case is approx. 50%.
Reversing is detected:
if a manual transmission fitted, the ME control unit is connected parallel to the reversing light switch.
if an automatic transmission is fitted, the information is supplied over the CAN by the ETC control unit.
