Welcome to YW! :thumbsup:
I believe that is the TPMS warning light. Check your tire pressure.

Yeah TPMS warning light. Check tire pressure. On in the morning when tires are cold and pressure is lower. Off later in the day as the tires have heated up, increasing the air pressure.

tire pressure. mine came on to on my 09' LB when i put the rims on since there is a sensor on the stock wheels. we couldnt figure out why it had came on at first and then the man at toyota service told me it was cuz i swapped the wheels. ive gotten used to the light being on and it doesnt bother me anymore. we checked the tire pressure just in case and it most definitely wasnt the cause. since winter is coming i will be swapping back to stock wheels again and i suppose the light will go back off:iono:.

Those batteries in the TPMS transmitter units are supposed to last 7 years. In a few years lots of people will be asking why those lights are on.
