CONTROL OF OPERATING PERIOD OF INTERIOR LIGHTS, FUNCTION - GF82.20-P-3001GH
MODEL 163
The switch-on time for the interior lights is controlled by the all-activity module (AAM) (N10) . All lights are
faded off.
When the doors are open the corresponding lamps are switched off after 30 min.
After closing the last front door or last rear door the corresponding lights are switched off after 10 s.
After recognition of a crash the interior lights are switched back off after 30 min.
When the ignition is switched on all of the lights are switched off immediately.

Lights switched on manually are not switched off by the AAM
SWITCHING OFF INTERIOR LIGHTS WITH FADE-OFF FEATURE, FUNCTION - GF82.20-P-3002GH
MODEL 163
The interior lights are faded on and off by the all-activity module (AAM) (N10) . For this purpose the lamps
are actuated by the AAM with a square wave voltage. The frequency of the square wave voltage is 122 Hz and
remains constant. Only the on/off ratio of the square wave voltage is changed during fade on from 0 to 100 %
within 2.5 s. When fading off the on/off ratio is reduced from 100 % to 0 % within 2.5 s.

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.

and for reading and loading navigation data from navigation data CDs.
A special navigation CD must be inserted for navigation purposes.
The CD player integrated into the radio and navigation unit (A2/56) provides the following audio functions:
Fast forward or reverse (music search) The music played is audible during fast forward or reverse.
"Scan" function
Each track on a CD is played for 8 s. After a complete run through, the scan function is automatically
terminated.
"Random" function
All the tracks on a CD are played according to a random selection.
"Repeat" function
The current track is repeated.
"Display" function
The number and elapsed playing time for the current track, the total playing time and the number of tracks
on the CD are displayed.
Each CD includes a permanently stored table of contents (TOC record). The table of contents (TOC entry)
contains information such as the number of tracks on a CD and the CD's total playing time.
CD playback is automatically interrupted by the following functions (pause function):
Traffic messages and public warning messages over the radio data system (RDS)
Incoming telephone calls
CD playback is continued at the position at which the interruption took place. No part of the track is skipped
during the pause function.
The CD playback volume is only reduced during navigation system voice output.

Title forward/backward
If the "joystick " is pressed to right the next CD title is skipped. Pressing to left within the first 10 s of
playback causes jumping to the previous title, otherwise to the beginning of the title presently being
played. If the" joystick " is held to left or right the changer jumps from one title to the next within short
time intervals without playing them.
Fast forward/rewind (music search)
If the "joystick " is pressed up or down the titles are played quickly. This allows specific parts of a title to
be played or skipped. When the start or end of the CD is reached the search is interrupted.
Title repetition and random playback
Random playback can be activated/deactivated with the multifunction " RDM " key. When activated this
function is indicated on the display and random playback can then be selected. The random playback
feature affects only the CD presently being played back. Title repetition can be activated/ deactivated
with the multifunction " RPT key. The title presently selected is repeated until the function is deactivated.
The random playback and title repetition remain active, even when the radio and navigation module
(A2/56) is switched off and switched back on again. Actuating these two functions simultaneously is not
possible.
Pause
The multifunction key" II "(Pause ) interrupts the title presently being played. Pressing again continues
playback.
Direct title selection
Pressing the " *" button followed by entry of the desired title via the number block allows direct selection
of the title.
Multifunction key Time
By pressing the multifunction key" Time " it is possible to change between 2 different display modes:
Display of title number and previous playback time of title (standard setting)
Number of titles and entire playback time of CD ("Time appears on display).
CD title assignment, function
Each CD has a permanently stored, so-called T able of C ontents (TOC ) entry. The radio and navigation
module (A2/56) recognizes the CD clearly on the basis of this entry and can automatically designate it (even
when the CD is then inserted into another CD ma
gazine) after the title has been assigned once by the user.

with toxic salts and

82 119 We receive at the diagnostic
centers of the plants more and
more xenon control units and
xenon lamps which are o.k.
To avoid this high number of
problem parts with no
reproducible faults, we would ask
you to use the following
procedure for troubleshooting:
1 Perform diagnosis according to
instructions in WIS.
Model 202, 208, 210AD82.10-P-1001AZ
If the fault cannot be
recognized or the faulty
component determined: ?
2 Interchange the xenon lamps
(right to left).
For the time being do not
replace system components.
If the fault of the xenon lamp
still exists: ?
3 Remove/install/replace xenon
lamp.
If the fault remains in the
headlamp the cause may be the
xenon control unit or a fault on
the vehicle side.
We are aware of the fact that
this procedure may possibly lead
to another stay in the workshop o
f
the vehicle in question.
However, we see no other
alternative if the redebiting of
warranty and goodwill costs is to
be avoided.
