Malfunction of the remote control
The remote control may not function correctly due
to local radio wave interference. The vehicle will
then not lock properly. This can be identified by the
missing locking sound and the missing check-back
signal of the emergency flasher.
If this should occur:
Lock the vehicle with the key in the door.
Emergency operation - opening
Unlock the driver's door with the key at the
door lock. Open door within 20 seconds and
insert the ignition key into the ignition lock
within 10 seconds to prevent the alarm system
from being triggered.
Note on operation
If the door is not opened within approx. 20 sec-
onds, automatic relocking takes place. The alarm
system will be triggered by the next unlocking of
the door:
Insert the ignition key into the ignition lock to
switch off the alarm system.
Emergency operation - closing
Lock the driver's door with the key at the
door lock. If there is a defect in the central
locking system, all functioning elements of
the central locking system will be locked. The
alarm system is switched on. The passenger
compartment monitoring system is switched
off.
The fault should be remedied immediately at an
authorized Porsche dealer.
Indication by emergency asher and
alarm horn
If the remote control is used for unlocking or
locking, a response is provided by the emergency
flasher:
– Unlocking - single flash.
– Locking - double flash.
– Locking twice - continuous illumination for
approx. 2 seconds.
Fault indication
A double horn signal during locking indicates a
defect in the central locking or alarm system. Have
the defect remedied at an authorized Porsche
dealer.
Overload protection
If the central locking system is operated more
than ten times within a minute, further operation is
blocked for 30 seconds.
