Question
my yaris t sport alarm keeps going off when ever the sun comes out i was told by e mail that my question had been answered when i clicked on they told me it hadnt been answered please could you help me out thank you

Answer
Hmmm, this an interesting question. What alarm do you have
in the car? Odd that tempeature would affect an alarm
system though. Also describe to me the sounds
(car horn or siren) or is it headlights or, parking
lights flashing?

Let me know & I'll try to help if I can.
