| Rectify tire pressure.
I just bought a certified 2007 GL 450. I have had it for a week. It is a great drive.
Today I had to reset the remote garage door opener. I think that if affected my TPMS. I have tried to reset my TPMS, but after shutting off the engine, I get "Rectify Tire Pressure" on the dash display.
Is there an easy fix to this problem or does the dealer have to reset the monitor? |
