2020 Alfa Romeo Stelvio Alarm System
The 2020 Alfa Romeo Stelvio has a strong safety system that makes the car safer and protects it from being broken into or stolen. This high-tech system has sensors in the door, trunk, and hood, as well as a glass-breakage sensor in some models, motion sensors inside the car, and an immobilizer to prevent theft. It is easy to arm and disarm with the smart key fob, which also has a panic button in case of an emergency. When the alarm is set off, it turns on a loud noise and flashing lights to scare away potential thieves and warn people nearby. Owners can change the alarm system’s sensitivity levels and make it fit their needs, giving them peace of mind when they park their Stelvio.
SECURITY ALARM SYSTEM
ALARM ACTIVATION
The vehicle security alarm monitors the vehicle doors and ignition for unauthorized operation. When the vehicle security alarm is activated, interior switches for door locks are disabled. The system provides both audible and visible signals. While armed, the alarm will sound in the following scenarios:
- Opening of doors/hood/liftgate (perimeter protection)
- Operation of ignition with a key that is not validated
- Cutting off the battery cables
- Movement inside the passenger compartment (volumetric protection — if equipped)
- Unexpected lifting/tilting of the vehicle (anti-lift protection — if equipped)
- Activation of the alarm triggers the acoustic warning and the turn signals.
NOTE: The alarm system is activated by the Engine Immobilizer system, which is automatically activated when you get out of the vehicle with the key fob and lock the doors.
TO ARM THE ALARM
With the doors, hood, and liftgate closed and the keyless ignition system placed in the OFF position, push and release the lock button on the key fob. The alarm can also be armed by pushing the Passive Entry door handle button, located on the exterior door handle. Refer to “Doors” in this chapter for further information. When the alarm is armed, the warning lights on the door handle trim remain on.
The activation of the alarm is preceded by a self-diagnosis stage: if a fault is detected, the system emits a further acoustic signal.
If a second acoustic signal is emitted after the alarm is already armed, wait about four seconds and disarm the alarm by pushing the unlock switch. Verify that the doors, hood, and liftgate are closed correctly. Then, reactivate the system by pushing the lock switch.
If the alarm emits an acoustic signal even when the doors, hood, and liftgate are correctly closed, a fault has occurred in the system operation. In this case, contact an authorized dealer.
TO DISARM THE ALARM
Push the unlock button on the key fob to disarm the alarm. While disarming, the following operations are performed:
- Two brief flashes of the turn signals (if programmed).
- Two brief acoustic signals (if programmed).
- The doors are unlocked.
The alarm can also be disarmed using the Passive Entry system, by grasping one of the Passive Entry front door handles with a valid key fob in hand to unlock. For further information refer to “Doors” in this chapter.
NOTE: The alarm does not disarm when the doors are unlocked by inserting the blade of the emergency key into the door handle lock cylinder.
VOLUMETRIC/ANTI-LIFT PROTECTION — IF EQUIPPED
The vehicle security alarm system monitors the doors and liftgate for unauthorized entry and the ignition switch for unauthorized operation. To ensure the correct operation of the protection, completely close the side windows. If a perimeter violation triggers the security system, the alarm will sound and the exterior lights will flash. To ensure the correct operation of the Volumetric/Anti-Lift Protection system, completely close the side windows. To disable the function, push the Volumetric/Anti-Lift Protection button before activating the alarm.
When the function is disabled, this is indicated by the light on the Volumetric/Anti-Lift Protection button flashing for several seconds.
Any disabling of the Volumetric/Anti-Lift Protection must be repeated each time the ignition is placed in the OFF position.
TO DISARM THE ALARM USING PASSIVE ENTRY
To completely deactivate the alarm (e.g. during a long period of vehicle inactivity), insert the blade of the emergency key, found inside the key fob, into the door handle lock cylinder and turn the emergency key to the right (clockwise) to lock the door(s).
