0408TLBoii

my car is acting a little funny i notice when i put my car in the on 1 position all of the dash lights turn on. now i know that on the 2nd position all of the lights turn on. shouldn't the 1st position turn the radio only. i was in my cousins 08 tl and i notice that we i put it in the 1st position only the radio turns on and not the dash lights. reminder i have an 05 tl. how can fix this.
