Anti-Theft Alarm System
The anti-theft alarm can be armed or
disarmed with the master key, valet
key or flat key by locking or unlocking
either front door or the trunk.
Operation
Once the alarm system has been
armed, the exterior vehicle lamps will
flash and the horn will sound intermit­
tently when someone:
• opens a door,
• opens the trunk,
• opens the hood,
• removes the radio,
• switches on or bridges the ignition
circuit,
• steps on the brake pedal.

The alarm will last approximately
150 seconds in the form of blinking
exterior lamps. At the same time an
additional horn will sound intermittent­
ly for 60 seconds, pause for 30seconds,
and repeat for another 60 seconds.
The alarm will stay on even if the
activating element (a door, for exam­
ple) 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! (This is indi­
cated by a dashed line across the
display.)
Do not give the master key to an
unauthorized person. We recommend
that you carry the flat key safely with
you so that it is always handy. This
key has the same function as the
master key.
Power Seats, Front
The switches are located in each front
door.
Turn key in steering lock to position 1
or 2 (with the driver's or front passen­
ger's door opened, the power seats
can also be operated with the key
removed or in steering lock position 0).
Seat and head restraint adjustment:
A Seat cushion adjustment.
B Seatback adjustment.
