This is something that I never had happen before with my 2009 Vibe.
As I left the car ( during the daytime) I heard a warning signal beeping. I saw the seatbelt symbol light on and didn't know anything else that I did to make it sound.
The car was turned off and in park as well.
Well when I came back to the car as it got dark outside, (coming from the store) I saw my red Tail reds on.
I opened the door and the signal sound came on again. I just started the car, went home. Again at home the light stayed on as well as the front turn signal lights.
The car was again off. Well I figured out that I turn on a light switch at the tip of turn signal arm.
Since I never had to fool around with light switches with the auto light setup, I nevered learn about this feature before.
In conclusion, I now learned how to turn on the lights with the motor off.
Nearly five years with this car and I'm still learning. LOL
