Turn signal indicator

ticking
Switching on the turn signal indicator is

indicated acoustically by the turn signal

indicator ticking. The driver's attention is

brought to a defect in the turn signal system

by the turn signal indicator ticking at a higher

frequency.

Turn signal indicator ticking is generated

electromagnetically. The frequency

corresponds to that of the turn signal indicator

lamp.

The signal comes from the combination relay

(turn signal indicator with trailer coupling, rear

window defroster), wiper motor, ATA (N10/2),

on model 210 from the multi-function control
module (N10-1) or from the driver-side signal-

acquisition and actuation module (SAM)

(N10/1), on model 163 from the All-Activity

Module (AAM, N10), on model 168 it is

generated by the integrated turn signal

indicator control in the instrument cluster (A1).

When the kick-down switch (S16/6) is operated via the accelerator pedal a signal is passed on to the ETC
control module (N15/3). Based on this information the ETC control module (N15/3) actuates the solenoid
valves so that the upshifts and downshifts take place at higher engine speed.
Shift-Lock Function
Operation
The term shift lock combines the functions which, in addition to the parking brake, offer an additional safeguard
for the vehicle to prevent it moving off unintentionally.
These include the functions of locking the selector lever position "P" and locking the ignition lock as well as the
parking lock in the transmission.
The shift lock function only allows shifting out of selector lever position "P" if the transmitter key (A8/1) has
been turned into the position "Ignition: ON" and the brake pedal is depressed.
In order to ensure that after parking the vehicle the selector lever is shifted into selector lever position "P", the
transmitter key (A8/1) can only be turned towards "0" in this position and removed from the EZS control
module (N73) (ignition lock locking, function).
The vehicle is secured mechanically by blocking the park pawl gear.
In the event of mechanical or electrical/electronic faults it is possible to unlock selector lever position "P"
manually (shift lock override function).

Function prerequisites:
Circuit 15 ON
Function
The headlamp cleaning system is switched on by pressing the SRA [HCS] switch (S4/1) .
The corresponding input of the Extended Activity Module (EAM) (N10/1) , which receives the input
from the switch, sends the signal to relay 5 (F2k5) .
The relay switches circuit 30 , for a duty cycle of approx. 1 second, through to the HCS pump (M5/2) .
The HCS pump (M5/2) builds up pressure in the washing water line.
The water pressure acts against the return springs of the telescopic nozzles.
The telescopic nozzles extend and spray washing water onto the headlamp glass.
After the duty cycle, the pressure in the washing water line drops again and the telescopic nozzles move
back to their starting position due to spring load.
Pressing the SRA [HCS] switch (S4/1) again during an ongoing headlamp cleaning cycle has no effect.
A further cleaning cycle can only be initiated after the previous cycle has ended.

The actual frequency is also a factor of the vehicle's speed of travel (see chart below).
The wiper is turned off by reactivating the wiper/washer switch.
The start of each wipe cycle is synchronized with the front wiper system.
Networking
Rain sensor (B38) and reverse signals are fed to the All Activity Module (AAM) (N10) via the engine
compartment CAN.
The settings of the rear wiper/washer switch (S78) are read directly by the All Activity Module (AAM)
(N10) .
The tailgate wiper motor unit (M6/4) is controlled directly by the All Activity Module (AAM, N10) .
The tailgate wiper motor unit (M6/4) comprises a relay and a cam-operated switch in addition to the
actual motor.

Program) appears on the radio and navigation unit display (A2/56).
Even when the RDS function is deactivated, the traffic station recognition and station following function remain
in operation (if activated). RDS alarm messages are still issued. In this case, CD playback or radio reception is
automatically interrupted.
2-tuner technology function
If interference occurs to reception while driving, the system attempts to receive the selected station on an
alternative frequency with the aid of the second (integrated) receiver and switch over when reception is better.
Moreover, the second radio receiver automatically generates a list of the receivable FM stations after switch-on,
and this list is continuously updated during operation. The stations contained in the list can be called up sorted
in alphabetical order with the station search buttons.
The station list is only available when the "RDS" function is activated.
At certain times, some radio channel programs are subdivided into regional programs.
Since the system automatically switches to an alternative frequency in the event of reception interference, this
can lead to a change in the regional program (not the radio network). If this is not desired, the regional program
function can be activated in the menu "REG". Switchover to an alternative frequency is then accomplished only
within the regional program.
FM antenna diversity function (models 209.3/4)
The antenna diversity function undertakes a reception-specific switchover between the FM antennas on the rear
window for model 209.3 (FM antennas of windshield for model 209.4). The function runs automatically and is
executed by the window antenna amplifier module 1 (A2/71) for model 209.3 (left antenna amplifier module
(A2/64) for model 209.4).
The radio tuner of the radio and navigation unit (A2/56) only generates the intermediate frequency (ZF) signal,
which serves as a reference to change the FM antenna for the window antenna amplifier module 1 (A2/71) on
model 209.3 (for model 209.4 left antenna amplifier module (A2/64)).
RDS Diversity/2-receiver technology function
The system consists of 2 FM receivers, a radio receiver and a search receiver. After turning on the radio system,
the search receiver automatically generates a list of FM stations received, which is continually updated during
operation.
Data such as reception quality, programs and alternative frequencies are stored. The audio receiver can therefore
switch over inaudibly to an alternative frequency. The list appears in alphabetical order when the "FM station
list" is called up. The stations which are displayed can be activated by selecting and confirming.

Navigation system - additional unit with CODE (818b) Single CD player - additional unit with CODE
(491) U.S. version
It is necessary to distinguish between audio and service sources on the radio and navigation module (A2/56) :
Audio sources are:
Radio
CD player
CC player
CD changer (code 819a)
Service sources include:
Voice output on navigation
telephone
Signal editing required for volume and tone settings is accomplished by the audio component integrated into
the radio and navigation module (A2/56)
If the vehicle is additionally equipped with a sound system (code 810), the sound amplifier (A2/13) ensures
final audio signal amplification.
Volume setting
By turning the volume knob the volume of the corresponding mode changes.
Tone setting
The tone settings as well as the general brightness adjustment of the display can be reached by pressing
the multifunction key" ADJ ". If the multifunction key" ADJ " is pressed for longer than 2 s all tone
settings of all modes jump back to the center position. This is confirmed by a short peep tone. The
adjustment possibilities for treble/bass, balance and fader are summarized in one display.
They can be selected by actuating the multifunction keys " " and " ". The corresponding setting can be
changed by actuating the multifunction keys"- " and "+ " or "L ", "R ", "F " and "R ".
These settings can also be made with the "joystick " in an analogous manner. When the headlamps are
switched on the brightness setting of the display can be reached by pressing the multifunction key" BRT" in the
tone setting menu. Here it is possible to select between " bright " and "dark ". Simultaneously pressing the
multifunction keys " - " and "+ " or "L " and "R " or "F " and "R " resets the corresponding setting in the
current mode to the center position
Tone setting is not possible in the telephone or navigation mode. The tone or brightness setting can be exited
by pressing the multifunction key EXIT ".
