exclamation mark on display and message saying inflate

i got the exclamation mark on the display and a message saying "inflate -4" on my front tire. when i look at the tire pressures though they all are at 33 PSI and the front tire in question isnt -4 its only -1 as its 32 PSI. I had not driven the car in a few months so not sure if thats what caused this but i drove for a few hours and I still get the error.

Is this an error that can be cleared somehow or is it another issue?

thanks

I've had similar error messages and went round and round trying to clear them. I finally had the tire shop fill them all for a long road trip (heavy load so they put ~40 psi) and all error messages went away. I know 40 psi is a bit high, but 33 psi seems to be on the low side. No error messages in the past couple of months after inflating as described.

you can set the pressure range of the alerts in the pcm - supposed to be done based on load and speed as well as wheel size

do you think 38 PSI all around would be a good compromise of handling and comfort?

it would be a compromise I would not make. Car is made for specific tire sizes, meaning will need specific inflation in each tire. Just run what the car designers asked for and you will be fine.

ah so it seems like pressure: 40 Fronts , 37 rear for 20 inch wheels for standard tire pressure
my understanding is comfort setting for softer ride and standard setting for better handling?

i have a 2010 pana s and i checked the manual and it says for comfort OR standard under partial load both of them say that it should be 32 pressure front and back, does that sound right?

I have a turbo. The thread was for a turbo. Your manual will h as vd proper setting for your panamera s. I recommend you follow your manual. Over or under jnflating can lead to tire wear and poor handling.
