Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Audible alarm
The emergency power siren receives a signal via the DWA bus when the ultrasonic interior movement detector triggers an alarm. It is fitted in the rear right wheel arch. The emergency current siren confirms receipt of the alarm request and triggers the audible alarm.
If the alarm request is not acknowledged, the anti-theft system will repeat the alarm request up to eight times.
Depending on the country-specific coding of the emergency current siren, an intermittent or interval tone is generated. If the anti-theft system is deactivated, the audible alarm is stopped immediately and without response.
