REAR WASH - FUNCTION - GF82.35-P-3001GH
MODEL 163
The rear wash function is activated by placing the rear wiper/ washer switch (S78) in the down position. The
switch contact connects the tailgate washer pump (M5/3) to terminal 15. The All Activity Module (AAM)
(N10) detects the activation of the switch via the second switch contact and actuates the tailgate washer motor
(M6/4) and the tailgate washer fluid pump (M5/3) for as long as the switch is on.
The activation time for the tailgate washer fluid pump (M5/3)is limited to 15 sec. To reactivate the pump, the
button must be pressed again.
To wipe window dry, the tailgate wiper motor (M6/4) remains activated for five seconds after the switch is
released.

As described for the rear wiper function, a relay circuit in the wiper motor stops the wiper in the park position .
WINDSHIELD WASH - FUNCTION - GF82.35-P-3002GH
MODEL 163
The windshield wash function is activated by pulling the combination switch, washer switch (S4s4) towards
the steering column. The switch contact connects the washer pump (M5/1) to terminal 15R. The All Activity
Module (AAM) (N10) detects switch activation via an input that measures power supply to the washer pump
(M5/1).
If the combination switch (S4) is in the Wiper Off or Intermittent position, the AAM activates the wiper
motor (M6/1) via rela

W4B035.
3.2 Automatic transmission fluids (ATF), sheet 236.2 , for MB passenger car and commercial vehicle
transmissions with non-ferrous metal synchronization except front-wheel drive manual transmissions of
the A-Class (see Section 2.5, Sheet 235.10), Allison transmission, commercial vehicle power steering,
hydraulic fan drive.
The ATF must meet all the requirements of the transmissions with nonferrous metal synchronization.
These include, in particular, wear protection against pitting and seizure as well as a defined friction
coefficient of the synchronizer components that is as constant as possible over the entire service life. As a
hydraulic fluid, the ATF is used for hydraulic power transmission and for protecting the hydraulic
assemblies from wear. The seal compatibility must be ensured with all elastomer materials used.
If the approved ATF are not available, engine oils according to sheet 227.0, SAE 10W or, depending on
the outside temperature, 20W-20 can be used in the above-mentioned synchronized manual transmissions
as a makeshift measure (queries should be directed to the Abt. Betriebstoffe EP/QWB (EP/QWB
Operating Fluids Dept.).
The approved ATF according to Sheet 236.2 correspond to the currently no longer valid GM specification
Type A Suffix A. 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.
3.3 Steering gear oil, sheet 236.3 , for all commercial vehicle steering systems, except vans T0 and T1N,
power steering systems for passenger cars, except
S-Class W220, power pack of the A-Class, and cross-country vehicles, manual steering L 075 Z for
passenger cars and manual steering in cross-country vehicle.
In the S class W220, in the Power-Pack of the A class as well as in the Transporters T0 and T1N as
of/below outside temperatures of 25°C the hydraulic fluids according to sheet 345.0 must be used.
3.4 Automatic transmission fluids (ATF) and/or engine oils, sheet 236.5 , for Allison transmission HAT
700
The oils listed here correspond to the Allison-C4 specification. Allison automatic transmissions in makes
AT 500, MT 600, S1000, S2000, World Transmission MD 3000, HD 4000 must only be filled with the
oils specified in Sheet 236.9 or TES 295.
If prior to starting the vehicle the gear oil temperature is below the critical temperature for the oil used,
then either the gear oil should be prewarmed or the transmission should be warmed up while in neutral.
Automatic transmissions in the model series CLBT 750 must only ever be filled with oils according to
Sheet 236.5. Under extreme operating conditions or for off-road use and/or with outside temperatures
higher than 30°C an engine oil of SAE grade 30 and/or 15W-40 from Sheet 236.5 should be used.
Depending on the outside temperature during vehicle operation, the oils used must be selected from the
followin
g diagram according to their SAE viscosity class and/or Dexron specification:

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,
