CONVERSION MEASURES RESULTING IN ALTERATION TO VEHICLE MODEL - AH00.10-P-1000-01A
Model 100, 107, 108, 109, 111, 112, 113, 114, 115, 116, 123, 124, 126, 129, 140, 163, 168, 170, 201, 202, 208,

We disapprove of all vehicle conversions resulting in an alteration to the model. A standard production vehicle
is a design entity which, upon installation of parts alien to the model, usually changes in a detrimental way.
Changes to important components influence the homogeneity of the vehicle in its entirety. For this reason we
have not investigated the details to be observed when performing such conversions. Such conversions can also
lead to changes on the vehicle which require new proof that the vehicle complies with legal requirements.
The main reasons for our disapproval are:
1. Subsequent installation of a component such as a more powerful engine may overload the remaining
components such as the transmission, brakes, axles, etc.

Fig. 644: Automatic Transmission Fluid Sheet
3.5 Automatic transmission fluid (ATF), Sheet 236.6 and 236.7 , for MB automatic transmissions
without regulated torque converter lockup clutch in passenger cars and commercial vehicles and buses
(W4B035 only as of major assembly end no. 005733), ZF Ecomat transmissions, Voith-Diwa
transmissions, commercial vehicle and cross-country vehicle power steering systems. If the approved
ATF according to sheet 236.2 are not available, ATF according to sheet 236.6 can be used in
synchronized passenger vehicle manual transmissions, except GL 76/30-5 and GL 275E (the two sports
transmissions always require ATF according to sheet 236.6) as a makeshift measure.
The approved ATF according to Sheet 236.6 and 236.7 correspond to the currently no longer valid GM
specification Dexron II-D. The kinematic fresh oil viscosity at 100°C must be at least 7.0 mm
2 /s, after
shearing (as per CEC- TLPG 7) at least 6.0 mm
2 /s.
3.6 Automatic transmission fluid (ATF), Sheet 236.8 , for ZF Ecomat transmissions, Voith-Diwa
transmissions, MB automatic transmissions in commercial vehicles and buses except W4B035 and MB
automatic transmissions without regulated torque converter lockup clutch in passenger cars (only in arctic
climates).
The approved ATF correspond to the no longer valid GM specification Dexron II-E, Allison C4, Voith
lubricant lists G 607 and G 1363 as well as ZF lubricant specifications TE-ML 14.
Automatic transmission fluid (ATF), sheet 236.81 , for MB automatic transmissions without controlled
torque converter lockup clutch in passenger cars, MB automatic transmissions in commercial vehicles and
buses except W4B 035 as well as ZF Ecomat transmission, Voith-Diwa transmission.
The approved ATF corresponds to the ZF lubricant specifications TE-ML 09, TE-ML 14 and the Voith
lubricant lists G 607 and G 1363.
Automatic transmission fluid (ATF), Sheet 236.9 , for MB automatic transmissions without regulated
torque converter lockup clutch in passenger cars, ZF Ecomat transmissions, Voith-Diwa transmissions,
Allison transmissions.

FRESH/RECIRCULATION SWITCH
Fresh/recirculation switch controls voltage signal to fresh air recirculation door motor. See Fig. 1 and Fig. 2 .
With switch indicator light on, air will recirculate. With switch indicator light off, air will enter from outside of
vehicle.
A/C CONTROL MODULE
The A/C control module (A/C amplifier) is the control unit for the A/C system. See Fig. 2 . The module
receives inputs from various sensors and processes the information to control various outputs for the A/C
system for optimal control.
The A/C control module inputs are as follows:
A/C Switch
In-Vehicle Air Temperature Sensor
Temperature Selector Knob
Blower Motor Knob
Evaporator Temperature Sensor
Air Mix Damper Door Position Sensor
The A/C control module output functions are as follows:
Air Mix Damper Door Motor
All Activity Module
Fresh/Recirculation Door Motor
ALL ACTIVITY MODULE
All Activity Module (AAM) receives inputs to determine if specified conditions have been met to allow
operation of A/C-heater system. If conditions are met, the AAM will send signals to the A/C compressor,
condenser fans relay and the blower motor relay to command or enable operation.
IN-VEHICLE TEMPERATURE SENSOR
The in-vehicle temperature sensor is a negative temperature coefficient resistor. Sensor sends signals to the A/C
control module to maintain in-vehicle temperature. Sensor is located on the center panel of the instrument
cluster.
DUST FILTER
A dust filter provides filtering of air entering or recirculating in the passenger's compartment. The dust filter is
mounted between blower motor and evaporator, below passen
ger's side of instrument panel, to left of blower
