Every 9-3 SS is equipped with an alarm function. This feature is not activated if no alarm option is purchased. Even though you have no alarm option, you can activate the alarm at the specialist / dealer with Tech2. Once the alarm is activated the flashing LED at the top of the front of your dashboard behaves like a LED of a car with full alarm. But with this activation only doors and the boot will be monitored. Also the a panic function on your remote is activated. The alarm can be heard on the standard horn.
