Hi, The button at the top is for traction control on and off. A Neutral position indicator for the letter N. The second button is for the drivetrain 4WD /AWD and the bottom button is for 4low--When in 4Lo, your truck is sending torque to all four wheels, but in the low range. 4Lo is best used on slippery surfaces. This can mean rain, sand, or even mud. While in 4Lo, your truck doesn’t get as much traction, but way more torque. 4Lo is also best used while driving at slower speeds (under 40 mph) and should be used if you need to “crawl” through a slippery surface. It’s also beneficial when you need more power for pulling heavy loads at slower speeds or climbing steep grades. You can also check your owner's manual for these functions for your reference.

The top one is to turn traction control on/off, the middle one is all wheel drive and the bottom one is 4low.
