iIf the service indicator was inadvertent-
ly reset, have a Mercedes-Benz Light
Truck Center correct it.
Only reset if the proper service has
been performed. Resetting the system
without performing the proper service
as called for by the FSS will cause the

The compass is calibrated in the factory in order to compensate

for deviations caused by magnetic field intensity of the vehicle and

magnetic interference when operating the heated rear window.

Once the compass is calibrated, it never needs to be recalibrated

under normal operating conditions. If a strong deviation in magnetic

field intensity is detected, the compass automatically recalibrates

itself.

A calibration must be carried out if the compass is replaced.
Additionally, the user can fine tune the compass in order to adapt

it to the vehicle's surrounding area. By setting the respective

compass zone, the compass compensates for deviations in the

earth's magnetic field.

The calibration should take place at least 10 m from any source of
interference such as power lines, buildings and parked vehicles.

General

The oil level is constantly monitored by the oil sensor, and the

appropriate data transmitted to the processor by the ASSYST.

Oil replenishments are detected automatically and result in a bonus,

which extends the service interval accordingly.

An excess oil level or insufficient oil level appears in the display

together with the oil can symbol.

Display of low oil level at maximum:
D
at driver request

Display of warnings: D
automatically, at the earliest 60 s after engine start and oil

temperature greater than 60°C:

D
if oil level too high: the oil can symbol appears together

with the readout "OIL LEVEL ABOVE MAX". In addition, a

brief warning signal sounds. (On models not fitted with

multifunction displaly, "HI" appears flashing.)

D
if oil level too low: the oil can symbol appears together with

the readout "OIL LEVEL BELOW MIN". In addition, a brief

warning signal sounds. (On models not fitted with multifunction

display, the oil level warning lamp (A1e12) comes on and the

readout "-2L" appears flashing.)

-----------------------------------------------------------------------------------------
D

if oil at minimum: the oil can symbol appears together with

the readout "OIL LEVEL MINIMUM". In addition, a brief

warning signal sounds. (On models not fitted with multifunction

display, the oil level warning lamp (A1e12) comes on.)

D
automatically 13 s after ignition ON:

D
if
no oil
is in engine: the oil can symbol appears together

with the readout "OIL LEVEL BELOW MIN". In addition, a

warning signal sounds. (On models not fitted with multifunction

display, the oil level warning lamp (A1e12) comes on and the

readout "-2L"appears flashing. In addition a brief warning

signal sounds.)

The missing oil quantity displayed no longer changes during the

display. In other words, any change in oil level cannot be observed

directly at the display. The new oil level is only displayed once the

conditions described below exist.

Display of oil quantity at driver request

The text "DISPLAY OIL LEVEL?" appears 10 s after the start switch

has been turned into position "2" (on models not fitted with

multifunction display, the oil can and the clock symbol are displayed).

If the reset button of the trip counter is pressed twice within one sec.

during this readout, for example, "add 1.0L oil" (or "-1.0L")

-----------------------------------------------------------------------------------------

appears in the display if oil level too low. The readout appears only

after the elapse of a waiting time after engine OFF. The waiting time

depends on the engine oil temperature.

It is

D
up to 20°C
30 minutes

D
from 60°C
1 minute

D
The waiting time is between these two limits at other engine oil

temperatures.

Possible readouts are (text in parenthesis relates to models not fitted

with multifunction display.):
D
"OIL LEVEL OKAY" ("o.k."),

D
1.0L, 1.5L, 2L,

D
"Overfilling" ("HI"),

D
"OBSERVE WAITING TIME" (clock symbol flashing and oil can

symbol),

D
"DISPLAY OIL LEVEL" (clock and oil can symbols.)

If there is a fault at the oil sensor (oil level/temperature/quality, B40)

the oil can symbol and the text "OIL LEVEL SENSOR FAULTY"

appears only 30 s after the fault has occurred.

(On models not fitted with multifunction display, the oil level warning

lamp (A1e12) comes on accordingly.)

For diagnosis, read also the injection system control module (N3)

with the HHT. (The instrument cluster (A1) receives the sensor data

through the CAN from the injection system control module (N3)).

-----------------------------------------------------------------------------------------
Oil change

The ASSYST has to be reset each time the oil is changed. Resetting

ASSYST also resets the remaining time and the remaining distance.

Resetting can be performed at the instrument cluster or using the

HHT.

The following data are stored when the system is reset:

D
current kilometer reading rounded off to 100,

D
total oil replenishments in the last interval,

D
remaining distance,

D
remaining time,

D
product of the quality factors,

D
the data of the last 5 resettings in 5 data sets

These data can only be read with the HHT!

If the specified quantity of oil is not replenished when the oil is

changed, the (internal) start distance is reduced.

Detecting oil replenishments
D
With the
HHT
it is possible to retrieve the last 10 oil

replenishments and the corresponding kilometer readings of

the current interval.

D
In the normal case, detection of an oil replenishment is

displayed by the remaining distance in the instrument cluster

being extended

P00.20-0202-06

Example 3:

When the oil was changed, the quantity

added was less than the specified quantity.

Consequently, the start distance is less than

15 000 km.

If oil is now topped up after 5 000 km (a), the

remaining distance displayed is not extended

as the curve is within the shaded area. The

bonus B1 is nevertheless added internally

and results in an extension of the service

interval to slightly more than

15 000 km - provided the driving conditions

remain the same or are more favorable.

(The service interval of 15 000 km is always

reached, however, even if the internal value

were less.)

P00.20-0203-06

Example 4:

Oil has been topped up after 5 000 km under

unfavorable driving conditions (a) and the oil

replenishment (bonus B1) detected internally.

We now have two cases to consider:

D
If the car continues to be driven under

the same conditions (unbroken line), the

remaining distance displayed is not

extended as the curve is within the

shaded area.

The service interval in this case is

nevertheless 15 000 km although the

internal value is less. (The remaining

distance displayed can always only be

within the light area.)

D
If the car continues to be operated

under more favorable conditions

(broken line), the value of the internal

remaining distance slowly moves into

the light area. Consequently, the service

interval may be greater than

15 000 km.
