LOCKING
SYSTEM
AND

ELECTRONIC
IMMOBILIZATION

The
central
locking
system
uses
electrical
lock
actuators
at

each
door
and
at
the
trunk
lid
.
The
locking
system
can
be
ac-

tuated
by
either
front
door
lock
or
by
the
luggage
compartment

lock
.
Onsome
1994
and
later
cars,
an
additional
remote
con-

trol
keypadcan
also
be
used
to
activate
the
lock
and
anti-theft

systems
.

When
the
key
is
tuned
to
the
lock
position,
a
micro-switch

signals
a
central
control
module
to
lock
all
doors,
luggage

compartment,
gas
tank
flap
and,
in
later
convertibles,
the

glove
box
lid
.
Where
applicable,
this
also
arms
the
anti-theft

system
.

the
locking
system
is
controlled
through
the
central
