my nissan versa 2012 have a this sign ! in yellow light,what is mean?

check your tire pressures...probably will go away then~

Are you sure it's an ! exclamation mark or maybe an arrow pointing up? If It's an arrow type symbol all that means it's time to shift gears if you have a manual transmission...many cars have that, vacuum and rpm sets it off.

No. Dave have seen the "yellow triangle" before...if only I could remember which context...it was tire pressure~

that would be groovy if the Versa was all that...it has a rental quality to it.~

Gotcha. I had that in an Audi I had years ago

...must have been nice to afford a "good" car, like that...when I bought the mercedes 230s (with the war-time fins) I was wholly unprepared for the adventure in realizing the Engineering mistakes of the past~ was nice to afford more than a meat-N-potatoes vehicle...the MINI makes motorists MAD because they wish they were that cute....fashion accessory much like the fiat 500 unabashedly uses Women to make it a fashion statement...more so then being able to be crushed between two semi's (and I've seen a Geo metro take one for the team)~
