Question regarding electronic stability control (ESC) on 2006 Tundra
 

What's the easiest way to determine if the '06 Tundra is equipped with electronic stability control (ESC)? Is there a button, knob, switch, dashboard light, etc that indicates ESC. Was ESC available on both 2-WD and 4-WD models? I'm considering purchasing a used '06 Tundra and want to get one with ESC but I understand that they are hard to find. Thanks in advance for any feedback.

Bump...Bump! Anyone here with an ESC equipped '06 Tundra???
