Anti-Theft Alarm System
The anti-theft alarm is automatically
armed or disarmed with any of your
vehicle's keys or infrared remote
control by locking or unlocking either
front door or the trunk.
A blinking lamp (1) indicates that the
alarm is armed.
The anti-theft alarm is disarmed when
unlocking either front door or the trunk
with any of your vehicle's keys or
infrared remote control.
Operation:
Once the alarm system has been
armed, the exterior vehicle lamps will
flash and the horn will sound
intermittently 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 alarm horn
will sound intermittently for 60
seconds, pause for 30 seconds, and
repeat for another 60 seconds.
The alarm will stay on even if the
activating element (a door, for
example) is immediately closed.
Note:
We recommend that you carry the flat
key safely with you so that it is always
handy. The flat key has the same
functions as the master key.
