GENERAL INFORMATION
NOTES ON SELF-LOCKING NUTS AND BOLTS - AH00.00-N-0001-01A
All models
Important repair information
Bolts with locking splines, micro-encapsulated bolts and self-locking nuts must always be replaced after
being used once.
There is an increased risk of injury when unscrewing micro-encapsulated bolts due to the sudden breakaway
torque.
Before new micro-encapsulated bolts are screwed in, the mating thread must be re-cut in order to remove all the
residue of the old bolt locking compound.
MEASURES FOR PREVENTING DAMAGE TO VEHICLES OR COMPONENTS WHEN PERFORMING ARC WELDING
WORK - AH00.00-N-0005-01A
All models
The following measures must be taken before welding in order to prevent damage to various vehicle
components:
1 Have fire extinguishers at the ready.
2 The negative terminal of the battery must be disconnected and covered up.
3 In vehicle with airbags the red, 12-pin test connection/plug-in connection must be disconnected no
sooner than two seconds after the battery has been disconnected (risk of unwanted activation).
6 Attach protective shields to prevent flying sparks and radiated heat in endangered areas.
7 Do not touch electronics housings or electrical cables with the welding electrode or the welder's ground
connection.
8 If two parts are being welded together, both parts must be attached to the welder's negative clamp.
9 Make direct connection between the electrical welder's ground connection and the part being welded.
Ensure that there are no electrically insulating parts between the ground connection and the welding
point.
10 Protect or remove any parts that are sensitive to heat such as plastic cables.
11 Remove electrical cables that are laid in cavities and/or pipelines, covered containers and electrical
components from the danger area before welding.
12 If possible, the points where the welded part is being attached to the vehicle and the ground terminal is
attached to the electrical welder must be bare; remove all traces of paint, corrosion, oil, grease and

ACTIVE SERVICE SYSTEM (ASSYST) INFLUENCING PARAMETERS - GF00.20-P-0003-05A
The values of various influencing parameters are required by ASSYST for calculating the demand-based service
interval, and these are included in the calculation of the service interval as weighting factors . There are two
versions within ASSYST, the difference being in the oil level sensors fitted:
The familiar oil level indicator switch (S43) is fitted to engines (104, 111, 119, 120, 602.982, 604, 605,
606). In view of the fact that this is a switch, it is only possible to detect if the oil level drops below the
minimum level.
The oil sensor (oil level/temperature/quality, B40) is used on more recent engines (e.g. 112, 113, 166,
611, 668). This sensor consists of 2 capacitor systems with the engine oil as an insulator. If the water
content of the oil or the oil level changes, there is a change in the capacitance of the "capacitor".
The capacitance is thus a measure for the oil level.
In addition, the oil sensor (oil level/temperature/quality, B40) contains a temperature sensor which
detects the temperature of the engine oil.
All the signals are processed in the electronics integrated in the sensor to form a PWM (pulse width
modulated) signal, and passed to the engine control module (N3).
In addition to the weighting factors, which depend on reallife driving conditions, quality factors are also used
for calculating the demand-based service interval (remaining distance and remaining time).
Survey of ASSYST influencing parameters
Weighting factors (dependant on reallife driving conditions):
Load torque
Engine speed
Oil level
Engine oil temperature
Oil correction factor (is used as comparative value for determining oil level)
Coolant temperature
These data are supplied by the injection system control module (N3) to the service microprocessor over
the CAN.
The data relating to oil level, engine oil temperature and oil correction factor are supplied by the oil
sensor (oil level/temperature/quality, B40) through the injection system control module (N3), and are
therefore only available on engines fitted with this sensor.
Quality factors (these are factory-set to base values and can be changed with the HHT, if operating
conditions of the vehicle so necessitate; they influence the start distance):

After a level has dropped below a warning threshold, the remaining distance or the remaining time is displayed
in text panel (b) and the tool symbol (a) appears in the display (top ill.). In addition, ASSYST features a low
engine oil level display. If the oil level is too low or too high, this appears in text panel (b) and the oil can
symbol (a) is displayed (bottom ill.).
( The illustrations relate to models with multifunction display. For other models, refer to document:
"ASSYST display facilities".)
Service A/B display
All models will feature an automatic display of the service (A or B) by no later than modification year 00/1.
More detailed information is contained in the document displaying service.
Fig. 320: Identifying Service A/B Display
In view of the complexity of the system, ASSYST features its own processor in the instrument cluster.
ASSYST is supplied with the time information from the electronic clock integrated in the instrument cluster.
The other data required are supplied over the CAN dataline by the traction systems control module (N47) and
by the injection system control module (N3).
CAN data required for ASSYST:
wheel speed signals for calculating the vehicle speed and distance (from traction systems control module,
N47)
Coolant temperature (from injection system control module, N3)
Engine oil temperature (from injection system control module, N3)
Oil level (from injection system control module, N3)
Engine speed (from injection system control module, N3)
Load torque (from injection system control module, N3)

2.6 Transmission oils, sheet 235.11
The fully synthetic gear oils are approved for all MB commercial vehicle manual transmissions installed
in MB vehicles with steel/molybdenum synchronization with and without oil coolers, in MB transfer
cases with and without oil coolers as well as in ZF manual transmissions with steel/molybdenum
synchronization.
Due to the favorable viscosity/temperature characteristics, a good cold-shifting response and, due to the
composition of the transmission oil, a good thermal/oxidative stability of the oil at high transmission oil
temperatures as well as a fuel savings potential depending on the operating conditions can be expected.
2.7 Engine oils, sheet 235.12
The engine oils must be used with a common oil system for transmissions used in tropical countries, and
for manual transmissions with a torque converter and clutch unit. These engine oils display the very high
seizure resistance required for use in transmissions. The oils need not comply with the engine oil pour
point specifications in these Specifications for Operating Fluids.
2.8 Engine oils, sheet 235.27
Commercial vehicle retarder oils: the products listed in the tables apply to commercial vehicle
transmissions: see MB Specifications for Operating Fluids 231.2. The engine oils are suitable for retarder
use. The oils need not comply with the engine Specifications for Operating Fluids 231.2. The engine oils
are suitable for retarder use. The oils need not comply with the engine oil pour point specifications in
these Specifications for Operating Fluids.
3. Automatic transmission fluids (ATF), sheet 236.1/.2/.3/.5/.6/.7/.8/.81/.9/.10/.11/.12/.13/.20
ATFs are comparatively low-viscosity gear oils which, due to their universal use potential as a gear oil or
a hydraulic fluid, can cover a wide spectrum of applications. The ATFs in the individual their universal
use potential as a gear oil or a hydraulic fluid, can cover a wide spectrum of applications. The ATFs in the
individual sheets differ essentially due to their inherent friction coefficients in tribological contact. This
property predestines these oils as function fluids for automatic transmissions whose ease of shifting,
among other things, is considerably affected by the friction coefficient of the ATF. Therefore, to achieve
optimum performance of the vehicles, only the ATF quality (sheet no.) assigned to the major assembly is
to be used. The individual ATF qualities will be described in greater detail below.
3.1 Automatic transmission fluids (ATF), sheet 236.1
The approved ATF correspond to the currently no longer valid GM specification Dexron II-D or the
currently valid GM specification Dexron III.
The field of application of these ATF includes MB automatic transmissions without controlled torque
converter lockup clutch in passenger cars, ZF Ecomat transmissions, Allison automatic transmissions,
Voith-Diwa transmissions and MB automatic transmissions in commercial vehicles and busses except
