Toggle2021-2023 Volkswagen ID.3 Alarm System Operation
Introduction
Volkswagen’s entry into the electric mobility market will be the all-electric compact car known as the ID.3, which will be unveiled in 2020. The ID.3 has a number of cutting-edge technologies, including an advanced alarm system intended to increase vehicle security, as of my knowledge cutoff in September 2021. The ID.3 is protected by the alarm system from entry, theft, and unauthorized access.
The alarm system on the ID.3 probably works by combining sensors and technologies to find any potential threats. These sensors might include door and window sensors, motion detectors, and even internal motion detectors. The alarm system would go on when a potential threat was detected, causing loud audible alarms and maybe sending notifications to the owner’s smartphone through a connected app.
Alarm System
Anti-theft alarm
- Depending on the vehicle equipment level, the vehicle may have an anti-theft alarm.
- The anti-theft alarm system monitors the doors, bonnet and the boot lid.
- The anti-theft alarm is activated automatically when the vehicle is locked using the vehicle key.
- If the vehicle is not opened with a valid vehicle key, the theft warning system is triggered and emits acoustic and visual warning signals for up to five minutes.
When does the system trigger an alarm?
-
- When a door that was unlocked mechanically with the vehicle key is opened.
- When the bonnet is opened.
- When the boot lid is opened.
- If the ignition is switched on using an invalid key.
- If there is movement inside the vehicle (in vehicles with interior monitoring) (→ Interior monitoring system and anti-tow alarm) .
- If the vehicle is lifted or towed (vehicles with anti-tow alarm) (→ Interior monitoring system and anti-tow alarm) .
- If the vehicle is transported on a car ferry or by rail (vehicles with anti-tow alarm or interior monitoring) (→ Interior monitoring system and anti-tow alarm) .
- If a bicycle carrier that is connected to the anti-theft alarm system is removed.
Switching off the alarm
-
- Unlock the vehicle using the unlocking button on the vehicle key.
- Grip the door handle (→ Keyless Access) .
The anti-theft alarm will not function correctly if the 12-volt vehicle battery is weak or discharged.
When the 12-volt vehicle battery is disconnected, the anti-theft alarm system can be triggered.
Interior monitoring system and anti-tow alarm

In the roof console: sensors for the interior monitoring system (arrows).
- The interior monitoring triggers an alarm if movement is detected in the interior of a locked vehicle .
- The anti-tow alarm will be triggered if the vehicle is lifted.
Switching on the interior monitoring system and anti-tow alarm
- Lock the vehicle. When the anti-theft alarm is switched on, interior monitoring and the anti-tow alarm are also active.
- Depending on the equipment, the function of interior monitoring may be impaired if a load guard is used.
Temporarily switching off the interior monitoring system and anti-tow alarm
The interior monitoring system and anti-tow alarm can be switched off temporarily in the Opening and closing submenu in the Infotainment system (→ Vehicle settings menu) . The interior monitoring system and anti-tow alarm remain deactivated until the next time the vehicle is locked.
To avoid false alarms, deactivate interior monitoring and the anti-tow alarm in the following situations:
-
- If any people or animals are to remain in the vehicle interior for a short period.
- If the vehicle is to be loaded onto another vehicle, transported or towed away.
- If the vehicle is to be parked in a car wash or a two-story garage.
Risk of false alarms for the interior monitoring system
Interior monitoring can only work properly if the vehicle is completely closed. Observe the legal requirements. A false alarm can be triggered in the following situations:
-
- If one or more windows are fully or partially open.
- If the glass roof is fully or partially open.
- If lightweight items such as loose pieces of paper or items hung from the interior mirror are left in the vehicle.
- If the vibration alarm of a mobile telephone is switched on.
- Permanent deactivation of interior monitoring and the anti-tow alarm is not possible.
- If doors or the boot lid are still open when the anti-theft alarm is activated, only the anti-theft alarm is activated. Interior monitoring and the anti-tow alarm are not activated until all doors and the boot lid are closed.
- SAFELOCK is also deactivated when the interior monitoring system and anti-tow alarm are switched off (→ SAFELOCK) .
