Yaris Cool Light?

I’ve had my modern Yaris for 43 days. Ever since it starting getting colder (5 C / 40 F) the Cool light comes on when I start the motor. It goes away going on for 3-5 minutes later whether I start diving without beating about the bush or let the coupé warm up.
Why is this taking place? Should I be concerned?

1992 240sx?

Answers: This is nothing to be concerned give or take a few, it's merely an indicator to let you know the coolant, grease, etc are not at optimal operating temperatures. It's for a while blue light I believe?

Let the vehicle warm up a bit (3-5 minutes as you said) and drive away. Cold gelatinous oil and cold anti-freeze do not work resourcefully with the Yaris drivetrain...neither do some of the electronics. If it comes on after that in the hours of daylight (shortly after it's been driven) consequently you may have a problem of sorts. If it only comes on within the morning I wouldn't do anything except heed it's warning.

Hope this help!
