Just finished Hibernating what should I check for?
 

Stored the car since November til now CLK500. Tires seem low on psi, I'm hearing a flat but it's not (haven't checked psi) Steering seems tough (added power steering fluid) hope it fixes that issue. Brakes makes a lot of noise... I should use brake cleaner? Need to buy a MAF and do my e-test. I do have a mil caused by the MAF needing to b replaced (cleaning was temporary) do I need to change my air filters too? Anything else?

I don't think too much bad can happen in 5 months. No need to add PS fluid unless it was low. If it was low enough to be noisy, you may have a leak. Your rotors may be rusty, but that will come off quickly. Brake fluid absorbs water, so if that has not been flushed recently it would not hurt. No need to change filters, but pulling them and blowing them off would not hurt. Good time for a bottle of Techron the tank. If mine sat cold for 5 months I'd probably change the oil for the heck of it.

Cleaned out my filters and damn they dirty lol still having a hard time taking out the MAF sensor -_- guess I'm doing my e test in a few days later than I thought . After the MAF I'll go check the tire pressure.
