Default light load button

What is the light load button for? Every time I push it, it blinks and doesn't come on... When do I use it? My truck didn't come with a manual so I thought I would try here first before I looked on the internet...

thanks

Are you referring to the o/d on off or tow/haul button?

No... the button is located below the A/C controls, it is next to the exhaust break button and it says light load on it...

It's there to adjust the pressure thresholds for the TPMS. (Personally a PIA if you ask me...)

With the light load button on, the tire pressures can be lower without the dash warning light coming on.

The pressure that you have to set your tires to for that to be activated is on the aft facing of your door. I think mine is 60 in front, 45 in rear. To turn it on, you must set your pressure, turn the key to the on position, and then press the light load button. It will stay on and your "tire pressure low" light will go off IF you have your tires to the specified load. Otherwise it'll just blink and then go back off. Hope this helps. I personally like it, but it would be nice if it didn't have the sensors at all. 70 psi is alot to run in the back all the time.

Man I have been trying to figure that damn thing out for two years, I have to run 70psi in my tires all the time to keep the light off. I am gonna try to deflate to the psi in the door jam and see if that will let me run with the light off. Thanks!

No problem. Yeah I have E load range tires on my truck, and I think it definitely saves on tire wear. I never ran em at 70 psi, but i'm sure it would be a bumpy ride and they would probably chop somethin aweful. I have been running them now almost 5k miles with the light load on, and they are wearing pretty even, but it's just about time to rotate em

start with your fronts at 60 and your rears at 70.
Turn the key to the on position, and lower the rears to 45. The light load light should now come on, and stay on.
