The factory alarm is armed
The blinking alarm light on the instrument cluster can indicate a few different issues. It may signify a malfunction in the vehicle's alarm system, such as a faulty sensor or wiring problem. Alternatively, it could be a reminder of a security feature, such as key fob detection or an unarmed alarm system. If the light persists without any alarms, it's advisable to consult the vehicle's manual or a professional mechanic for diagnosis.

Which warning light is it?
The blinking red light under the windshield on the driver side indicates that the car has not been locked with the key fob. Using the key fob to arm the theft alarm system turns the red light continuously on.
