1. Hypoid gear oils
Hypoid gear oils contain a high level of EP/AW additives (Extreme Pressure/Antiwear) and a highly
viscous base oil to prevent seizure when the hypoid gears mesh (mixed and boundary friction conditions)
and to ensure a high degree of protection against wear. The compatibility with radial shaft seals is
regarded as critical with such high concentrations of additives because the P/S additive systems become
thermally unstable at temperatures from 130°C to 140°C and this may lead to sludging of the hypoid oil.
The resultant deposits on the radial shaft seals then generally lead to thermal overload and this in turn
leads to leakage in this component.
The tooth engagement conditions of the hypoid gears result in a high proportion of sliding and a low
hydrodynamic proportion of tooth engagement between the pinion and ring gear. Due to the high
tribological load compared to adhesive wear (seizure) and pitting, the performance of hypoid gear oils
must be particularly high with respect to these types of wear. The formula of the oils is therefore
determined by a high concentration of EP/AW additives and a highly viscous base oil. Alternative oils,
e.g. engine oils, cannot be used for these drive types. Proof of performance that an oil fulfills the
requirements of DaimlerChrysler AG is provided by internal tests. However, the hypoid gear oils must at
least correspond to the US military specification MIL-L-2105 B/C/D and must be classed GL-5 in the
quality grade according to API (American Institute of Petroleum).
1.7 Viscosity requirements
The cold flow behavior is only specified for SAE, ... oils. Here, the limits apply according to SAE J 306
c, according to which the dynamic viscosity may be max. 150,000 mPas at -40°C for oils and at -12°C for
oils. As a result of the tendency to form deposits in the transmission, the polymer content is limited to
max.
1 percent by weight for pour point reducers. Polymers as VI improvers for thickening low-viscosity base
oils are not permitted. The kinematic viscosity at 100°C must be at least 16.5 mm
2 /s.
2. Transmission oils, sheet 235.1
The additive and viscosity properties of the transmission oils are adjusted so that they meet all the
requirements placed on manual transmissions with steel/molybdenum synchronization, spur gear axles,
MB and ZF transfer cases and reversing gears. Among other things, this results in the fact that the oils
ensure a defined friction coefficient of the synchronizer elements, even after a high number of shift
operations, without crunching noises.
With gear drives and roller bearings, the adhesive wear (seizure) and pitting in particular should be
minimized as far as possible.
2.1 Viscosity requirements
The cold flow behavior is only specified for SAE, 80W, ...oils. Here, the limits according to SAE J 306 c
apply, according to which the dynamic viscosity may be max. 150,000 mPas at -40°C for oils, at -26°C
for oils and at -12°C for oils. Due to the formation of deposits in the transmission, the polymer content is
limited to max. 1 percent b
y weight for pour point reducers. Polymers as VI improvers for thickening

All models fitted with air conditioning
Do not carry repair operations out on the air conditioning circuit in the open air during moist weather.
Moisture in the refrigerant circuit reduces the system's refrigeration output and leads to damage to the
components. The acidic substances produced by moisture within the system decompose the desiccant in the
fluid reservoir and damage the entire system.
After separating/unscrewing refrigerant lines, immediately seal off the connection openings so that they are
airproof using suitable stop plugs (parts kit).
Replace the fluid reservoir every time you open up the refrigeration circuit.
Always store all spare components in a dry, sealed-off area. Do not remove stop plugs in new components until
just before they are installed. Use special care when handling the receiver/dryer with its integral desiccation
unit.
When a receiver/dryer is left open, the dryer unit quickly becomes saturated with moisture, rendering it useless.
Check drier cartridge packaging for damage. Dispose of drier cartridges with damaged packaging.
Install the desiccant cartridge no later than 20 minutes after opening the packaging.
Further protection against moisture is provided by carefully evacuating the air conditioning system following
repair operations. By generating vacuum in the system, the evacuation process removes any moisture that might
have penetrated into the system.
NOTES ON RETROFITTING AN AIR CONDITIONING SYSTEM - AH83.30-P-0001-02A
Do not remove the plugs on any of the components until immediately prior to installation.
Fit all AC lines with new sealing rings. Coat thread and sealing rings with compressor oil.

The blower regulator then controls the blower motor operating voltage, depending on the actual measured in-car
temperature and the selected target temperature
(0-12 V). This facilitates blower speed control of 0-100 %.
DUST FILTER, LOCATION - GF83.10-P-2104-01GH
The dust filter (1) is behind the instrument panel bottom section at the passenger side in the heater/evaporator
housing.
Fig. 7: Identifying Dust Filter

REAR VENTILATION, FUNCTION - GF83.10-P-2105-01GC
Function
The louvered-type flaps in the rear vent open from the pressure of the air flowing through the vehicle and allow
it to exit.
If a vacuum is present in the vehicle, as happens when driving with a window or the sliding roof open, the flaps
close automatically due to the force of gravity. This prevents exhaust gases, dust and moisture from being
sucked in.
REAR VENTILATION, LOCATION - GF83.10-P-2105-02GH
The rear vents (1) are located on the left and right behind the rear bumper.
