Anti-Theft Alarm System - Mercedes-Benz 560 SL 1986 Owner's Manual

Anti-Theft Alarm System

The anti-theft alarm can be armed
or disarmed with the master key
(identified by red dot) by locking or
unlocking either door or the trunk.
Operation
Once the alarm system has been
armed, the exterior vehicle lamps
will flash and the horn will sound
intermittently when someone tries
to:
• 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. towing
away.
The alarm will last approximately
150 seconds in the form of blinking
exterior lamps. At the same time an
additional horn will sound intermit­
tently for 60 seconds, pause for
30 seconds, and repeat for another
60 seconds.
The alarm will stay on even if the
arming element (a door, for
example) is immediately closed.
Note:
If the radio is removed from its
mounting when the anti-theft alarm
is armed the radio will automatically
be rendered inoperative!
To avoid setting off the alarm unin­
tentionally, do not arm the alarm
system in the following situations;
e.g.: Auto ferry, auto train, when
hitching/unhitching a trailer, or
heavy loading/unloading. For this
purpose use the valet key and not
the master key for locking the
vehicle.
Special Function
To activate the anti-theft alarm from
the trunk, turn the master key in
the trunk lock completely to the
right and pull it out in this position.
If you want the alarm system to be
armed at the trunk only, turn the
master key in the trunk lock com­
pletely to the right and pull it out in
that position. Then disarm the rest
of the vehicle by unlocking either
door with the master 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.
