Central Locking System - Mercedes-Benz 190E 2.3 1987 Owner's Manual

Central Locking System

The entire vehicle may be locked
or unlocked with the central locking
system:
• Using the master or valet key in
either front door.
• Using the master key in the trunk
lock.
• By pushing down or pulling up the
interior door lock button at either
front door.
The central locking system locks or
unlocks all doors, trunk lid and fuel
filler flap simultaneously.
Doors
When you lock the car, all door lock
buttons should move down. If any one
stays up, the respective door is not
properly closed. You should then un­
lock the car, open and reclose this
door, and lock the car again.

Note:
The central locking system can be
engaged from the driver-side door lock
button, provided the door is complete­
ly closed. It can also be engaged from
the passenger-side if the ignition key
is removed, or inserted in the steering
lock without being turned (key in posi­
tion 0).
If the car has been locked from the
outside with the master key, the anti­
theft alarm will come on if a door is
opened from the inside, or if opened
with the valet key.
Trunk
To unlock the trunk with the central
locking system, turn the master key in
the trunk lock completely to the left
and let it return to the vertical position.
Push in trunk lock button and open the
trunk. To lock the trunk, turn the mas­
ter key completely to the right and let it
return to the vertical position.
The trunk can remain locked while the
central locking system is unlocked
(e.g. while driving or when leaving the
car in a situation where it must be
driven using the valet key but you wish
the trunk to remain locked at parking
lots, workshops, etc.). Turn the master
key completely to the right and pull it
out in the horizontal position. Now the
trunk can only be unlocked with the
master key by turning it back comple­
tely to the left.
Important!
If the trunk is unlocked with the master
key, the doors and fuel filler flap will
also be unlocked. After closing the
trunk, the central locking system must
again be engaged using the key to re­
lock the doors, and fuel filler flap.
Note:
If the fuel filler flap cannot be opened,
refer to " Unlocking of Fuel Filler Flap"
(page 79).
