I bought my new Mazda 5 3 months ago. Yesterdayat night , I notice that the interior instruments lights are not as bright as before. I can barely see the lighting of the radio and the a/c also.

I looked in th owner's manual to see is there is a buttom to adjust the interior lights with no success.

Can someone tell me how to ressolve this?

 

My owners manual (page 5-30) says to rotate the **** to the left of the odometer "to adjust the brightness of the instrument cluster and the other illuminations in the dashboard." There are some other notes on the page that you might want to check out.
