The LTP warning light has appeared and remains. The dash shows cold tire pressures of 28. Does anyone know at what pressure the warning goes into effect?
Thank you

 

It depends on what tire pressure was set when the reset button under the dash was pressed. (It uses that pressure as the baseline then warns when it's a certain percentage lower). I don't remember the details, but you need to set all the tires to the correct pressure and press this button to tell the system what pressure your tires need. I think if you'll search there's a couple thread that discuss how to do this.

 

Thank you. I'll look for the threads, but I'm not much good at DIY. I'll see if Discount Tire can do it when I go there to have them put 31lbs in the tires. That, or 30, is my choice because I find the ride too harsh at the recommended 33.,
