First Off.....I picked up this E500 and love it! I am kinda annoyed at somethings. I keep getting a message saying to reactivate the tire pressure system. I looked at the manual and I cannot the the screen where all 4 tire's psi shows, it says it is deactivated.....what should i do?!?!

Its possible the previous owner added/removed the system to the car & it needs programming to know its there/not there.

I don't know? I got a message on teh dash after driving saying Tire Pressure Monitor is inoperatipal?

On mine there is no screen that shows all 4 tire pressures. It just tells you to check tire pressures when one of them is low. There's a procedure for resetting the TPMS. Did you try that? it's explained in the manual.

i tried too but it says it is inoperatable....soo i cant reset it unless the tire pressure actually shoes up

You have to have sensors in 4 wheels that are working, i.e. batteries have not failed.

djrabbi

how would i know if they failed?

MB dealer or independent can check sensors via DAS life expectancy is 5 to 7 years. Components consist of 4 wheel sensors, 4 antennas in wheel housings and control module located at left side of trunk behind rear SAM. The place to begin would be to inspect wheel sensors that may need replacement. Sensor part #0008224806 (for comparison shopping, parts.com $128.80) and just in case front/rear, left/right antenna 0018274801 (66.70), control module 2115406245 (342.70).
