4-channel power amplifier for vehicle loudspeakers
System interlinkage
The radio and navigation unit (A2/56) is provided with the following components for data exchange with
external digital components:
CAN (A1 -A2/56)
The radio and navigation unit (A2/56) is connected with the instrument cluster (A1) via a separate
CAN bus. The difference to the other CAN systems is indicated by the spelling CAN bus (A1-A2/56).
The CAN bus (A1-A2/56) allows the following functions:
Operation of the radio and navigation unit (A2/56)is also possible with the multifunction steering
wheel.
The multifunction display (A1/p13) in the instrument cluster (A1) can display navigation
information on the current operating status of the radio and navigation unit (A2/56) .
The connection to the CAN bus (A1-A2/56) is only realized on models 208 and 210. (Status 3/99)
Digital data bus (D2B)
Data can be exchanged between the external audio components, the telephone system and - if present -
the voice control system over the D2B bus. This allows control data as well as the actual audio signals
(e.g. music from CD changer) to be transferred.
The only additional D2B component presently possible is the CD changer (A2/6) (Status: 3/99)
K bus (diagnostic interface)
Data exchange is accomplished between the diagnostic interface and the hand-held tester (reading out
DTCs and actual values, ...).
The communication between the HHT and all other D2B components is accomplished over the radio
and navigation unit (A2/56) diagnostic interface.

The navigation processor recognizes the direction of motion (forward or reverse) from the reverse signal.
Direction in which vehicle is pointing
From the data of the gyrosensor and the sequence of the locations calculated with GPS the navigation
processor the calculates the direction in which the vehicle is pointing (compass direction).
The difference between calculated and actual distance traveled between two turning points is used for automatic
recalibration of the tire circumference (required due to tire wear).
Location finding errors during basic location finding
Rolling backwards without the reverse gear engaged is evaluated as forward motion, and may lead to an error in
the location finding.
Rolling with the ignition switched off or vehicle transportation also falsify map matching.
In both cases the deviation is automatically corrected by the navigation processor after receiving GPS data .
Calibration
Wheel calibration is not required following tire change.

wheel tires. Wear on the rear tires is uniformly

distributed across the total tread, whereby

wear on vehicles with rear-wheel drive in the

low-viscosity base oils are not permitted. The kinematic viscosity at 100°C 2 must be at least 9.5 mm /s.
In hot zones, gear oils of SAE grade 90 are also permitted.
2.2 Alternative transmission lubricants for commercial vehicle synchromesh transmissions which are
operated with transmission oils as per sheets 235.1, 235.5.
If there are no gear oils according to Sheet 235.1 and 235.5 available, the following engine oils can also
be used as alternatives:
In a moderate climate, engine oils of SAE-grade 30 as per sheet 235.12
In tropical climate, engine oils of SAE-grade 40 as per sheet 235.12
2.3 Fully synthetic transmission oil, sheet 235.4
Completely synthetic gear oils are imperative for the Unimog manual transmission UG 3/40, UG 3/65 and
the PTO transmission -as of the vehicle end No. ...179909 -. Older vehicles can have their oils changed
from gear oils according to Sheet 235.1 to gear oils according to Sheet 235.4 when an oil change is due.
The gear oils correspond to the ZF lubricant specifications TE-ML01 and TE-ML02 and are consequently
alternatives to the gear oils according to Sheet 235.1 in all synchronized ZF manual transmissions
installed in MB vehicles, with and without intarders. Furthermore, the approval extends to the MB
transfer case VG 2400 without oil cooler. 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 can be expected.
2.4 Transmission oils, sheet 235.5
The gear oils are approved for MB and ZF manual transmissions with steel/molybdenum synchronization,
MB and ZF transfer cases and corner gears.
The transmission oils have a low chlorine content as well as a potential for lower oil temperatures under
certain operating conditions.
2.5 Transmission oils, sheet 235.10
The partly synthetic gear oils are approved for the commercial vehicle manual transmission Model
G16/G28, for the passenger vehicle front-wheel-drive manual transmission SG 150/180 (A class) as well
as for all passenger vehicle in-line transmissions of the model series 717.4 as of transmission serial
number 7 340 241.
Due to the favorable viscosity/temperature characteristics, a very 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 can be expected.
With regard to the use in passenger vehicle front-wheel drive manual transmissions/in-line transmissions,
which are also installed in cross-countr
y vehicles, the approved gear oil is usually only used in the event

Because the brake fluid also absorbs moisture through the vent bore on the expansion reservoir, the wheel brake
cylinder and the brake hoses, the brake fluid has to be changed for safety reasons at regular intervals, best done
in the spring. When performing this change, make sure that the old fluid is also drained off the clutch system.
Generally, it is vital for the brake/clutch system to be completely drained before being filled with new fluid!
For the above-mentioned reasons, used brake fluid must not be used again.
The brake fluid is amber in color and thus can be easily confused with mineral products.
Therefore, brake fluids should always only be taken from original containers and stored separately from other
mineral oils and fluids.
When performing maintenance operations and repairs on brake parts, make sure that fuel, mineral oil, grease or
suchlike do not enter the brake system. Hydrocarbon-based materials will lead to swelling of the elastomers in
the brake and clutch system and - even in low concentrations - will suffice to cause total failure of the systems.
Only new brake fluid may be used as a rinsing and cleaning agent for the cylinders, lines and the expansion
reservoir of the hydraulic brake system.
Experience shows that before handling brake fluid, the hands must be cleaned and any oil and grease removed.
Brake fluid acts aggressively towards paint and color. In the event of any brake fluid spills or splashes, it must
be rinsed away immediately using copious amounts of water (do not rub it away).
Brake fluid disposal
When disposing of brake fluid, the relevant national specifications must be observed. It is advisable to try to
have the brake fluid disposed of as economic good; this is contingent on
Strict separation of used brake fluid from other materials;
Presence of a disposal channel, which justifies its classification as an economic good, i.e. a proper
alternate usage must be assured.
If this procedure is not possible, used brake fluid is to be disposed of together with any, e.g. paint residue,
solvents and suchlike. Any adding of used oil must be avoided, as it will result in difficulties, if the used oil is to
be recycled; in several countries this is prohibited by the legislators.

NOTES ON SCRAPPING GAS-FILLED HYDRAULIC COMPONENTS - OS00.00-P-1000-01A
all
Unusable gas pressure dampers, spring accumulators, pressure reservoirs and impact absorbers have to be
depressurized before being scrapped according to the respective valid accident prevention regulations. These
safety measures are necessary because gas pressurized hydraulic parts can explode if heat is applied. A risk of
explosion is
given, e.g. when scrapping with cutting torches, smelting or if gas pressurized parts in landfills start
