try to search for a relay or fuse for your headlight, most likely you will see a relay since there is only a single fuse for both headlights. meaning of this fuse blows off, both headlights will not turn on. relays are attached to each headlight, so if one goes off, the other one will still work.

That sticker will give recommended tire pressures for front and rear tires.

There should be a button in your center console (in front of the gear shifter) with this same image on it -- hold down that button for 5 seconds to see if it resets the indicator light.
