Anti-Theft Alarm System - Mercedes-Benz 190 E2.3 1985 Owner's Manual

Anti-Theft Alarm System

The anti-theft alarm can be armed or
disarmed with the master key (iden­
tified by red dot) by locking or un­
locking either front door or the trunk.
Operation
Once the alarm system has been
armed, the vehicle lamps will flash and
the horn will sound intermittently when
an unauthorized person tries to:
• open a door
• open the trunk
• remove the radio
• switch on or bridge the steering
lock
• 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, and repeat for
another 60 seconds after a 30 second
pause.
The alarm will stay on even if the
arming element (a door, for example)
is immediately closed.
To avoid setting off the alarm uninten­
tionally, do not arm the alarm system
in the following situations; e.g.: auto
ferry, auto train, when hitching/un­
hitching a trailer, or heavy loading/
unloading. For this purpose use the
supplementary 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 completely to the
right and pull it out in that position.
Then disarm the rest of the vehicle by
unlocking either front door with the
master key. You can now lock or un­
lock the doors and filler flap, as well as
start the engine, in the usual manner
using the supplementary key.
Do not give the master key to an un­
authorized person. We recommend
that you carry the flat key safely with
you (e. g. in your wallet) so that it is
always handy, if needed. This key has
the same function as the master key.
