Anti-Theft Alarm System - Mercedes-Benz 300SDL-TURBO 126 D 1986 Owner's Manual

Anti-Theft Alarm System

The anti-theft alarm can be armed or
disarmed with the master key (identi­
fied by red dot) by locking or unlock­
ing either fro nt door or the trunk.
Operation
Once the alarm system has been
armed, the exterior vehicle lamps will
flash and the horn will sound interm it­
tently when someone tries t o :
• open a door
• open the trunk
• open the hood
• remove the radio
switch on or bridge the ignition
•
circuit
step on the brake pedal
•
raise the vehicle, i.e. tow ing away.
•
The alarm will last approximately
150 seconds in the form of blinking
exterior lamps. A t the same time an
additional horn will sound interm it­
tently fo r 60 seconds, pause fo r
30 seconds, and repeat fo r another
60 seconds.
The alarm will stay on even if the arm­
ing element (a door, for example) is
immediately closed.
N ote:
If the radio is rem oved from its
mounting when the anti-theft alarm is
armed the radio will automatically be
rendered inoperative!
To avoid setting off the alarm uninten­
tionally, do not arm the alarm system
in the follow ing situations; e.g.: A uto
ferry, auto train, when hitch in g/
unhitching a trailer, or heavy loading/
unloading. For this purpose use the
valet key and not the master key fo r
locking the vehicle.
Special Function
To activate the anti-theft alarm from
the trunk, turn the master key in the
trunk lock com pletely to the right and
pull it out in this position.
If you w ant the alarm system to be
armed at the tru n k only, turn the mas­
te r key in the tru n k lock com pletely to
the right and pull it out in that posi­
tion. Then disarm the rest of the vehi­
cle by unlocking either fro n t door with
the m aster key. You can now lock or
unlock the doors and filler flap, as well
as start the engine, using the valet
key.
Do not give the master key to an
unauthorized person. We recom mend
that you carry the flat key safely with
you (e.g. in your wallet) so that it is
always handy. This key has the same
function as the master key.
