Normal???

Just picked up a new 2013 TRD off road 4x4 automatic on Saturday......
I havent driven an automatic in a LONG time and was curious if somethings were normal.......

Intermittantly, after sitting at a stop for about 10 seconds, the truck seems like it "settles"...like the brakes release for 1 second then it stops again.....
pedal feels solid, no mushy....doesnt feel at all like a master cylinder is goiing out....

and

seems to have more power off idle when cold.....
(i'm pretty sure that one is all in my head)


and last question......stock stereo, touchscreen....didnt need the nav so I didnt get sat...I WANT SAT RADIO....what is the best way to proceed with that? One radio shop said that I need 2 modules, was very vague and wouldnt give me specifics, so he is an automatic out for me.....

 

Answers in red....

 

i suspected it was my lazy foot holding the brake this morning, so I made a point of moving my seat up, and making sure, I had the brake down hard.....the A/C wasnt on, but the fan blower motor was....
Didnt do it on the way home with everything off, so i'm wondering if it is load on engine RPM related.....

 

The 2 defrost setting use AC
