I started playing around with our S (this is our first Toyota ever). And I see the following on the left hand side of the turn signal:
A red LED blinks on the "Security". Does this mean we have an alarm already? It doesn't matter if the car is locked or unlocked with the keyless entry key fob, that "Security" red LED blinks no matter what. So I figured I'll open the windows so I can reach in and unlock the car manually from the outside and open the door...I did not hear a car alarm when I did that.
