Does anyone know what the "Light Load" button does? Whenever I push it, it blinks three times and then goes off, but I cant see where it does anything. I couldnt find anything about it in the manual either.

 

With the "light load" button illuminated, the TPMS (Tire Pressure Monitoring System) will trigger an alarm when the rear tire pressure falls below 45psi. With the "light load" button NOT illuminated, the TPMS will trigger an alarm when the rear tire pressure falls below 60psi. The "light load" button does not affect the trigger point of the front tires (they are set to 60psi always).

so if you lower your air pressure in your rear tires to say 45psi, because you won't be towing any HEAVY loads, the TPMS light will illuminate, IIRC, you can press the light load button and it will make the TPMS light go out and the light load light should come on.

 

Ok thanks, I never would have guessed that is what it was for. Should mine blink though or stay on all the time when I press it?

 

i edited the above post that i think answers that question
