!Vehicles with rain sensor*:
Do not leave windshield wipers in inter-
mittent setting when the vehicle is tak-
en to an automatic car wash or during
windshield cleaning. Wipers will oper-
ate in the presence of water sprayed on
the windshield, and wipers may be
damaged as a result.
The switch should not be left in inter-
mittent setting as the wipers will wipe
the windshield once every time the en-
gine is started. Dust that accumulates
on the windshield might scratch the
glass and / or damage the wiper blades
when wiping occurs on a dry wind-
shield.
!If anything blocks the windshield wip-
ers (leaves, snow, etc.), switch them off
immediately.

For safety reasons, withdraw key
from steering lock before attempt-
ing to remove any blockage.


Remove blockage.


Turn the windshield wipers on
again.
If windshield wipers fail to function at
all in switch position1,


set the combination switch to the
next highest wiper speed


have the windshield wipers
checked at the nearest authorized
Mercedes-Benz Light Truck Center

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

(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
y F1k17 . To wipe windshield dry, the motor continues to operate after the switch has
