Dropped by the service dept and they had me worried. Please help to confirm

1) The auto transmission fluid can and should be changed. But it requires being able to monitor internal temperature (eg, CONSULT) in able to get the level correct. How often should it be changed? Depends on how you drive. I had mine changed at ~23k and I don't drive all that hard, but I tend to be very conservative when it comes to changing lubes and other fluids. Personally, I wouldn't go past 30-40k before the first change. After that, 60k ought to be good enough for most.

2) I had my differential fluid changed at ~15k. I like to change out diff fluid pretty early the first time and then mainly just keep a eye on the level and wait until the fluid starts looking dirty. From what I hear, it's a pretty easy DIY.

3) Yes, there is a cabin air filter. The '09's didn't have one installed at the factory but all the hardware is there; just buy a filter and install it. How often to change the filter varies widely with how much dust/pollen/&c there is where you drive and how much you run the HVAC. If you remove the battery lid and the surrounding cover in the engine bay (see some of the steering lock fuse removal (SLU or ESCL) DIYs for instructions), you can do a visual check of the filter. DIY is not that difficult but you have to remove the glove box which can be a PITA the first time you do it. There is a wide selection of filters available (same air handler as in many other Nissan/Infiniti cars). See some of the filter change DIYs for more info.

4) I usually replace belts on an as-needed basis. Do frequent inspections. A fairly easy DIY if you have the right tools and some mechanical experience.
