Blinking red light on auto light 2009 Hyundai Santa Fe?

Answer 1

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. In other words, the blinking is to remind the driver that the car is not locked (but will also be visible to any passerby, which is really a dumb feature of the car...why advertise the fact that the alarm system hasn't be activated?).
