Just bought a used 2011 RX350 and noticed that the liner on the driver side has vents on the front part while the passenger side has no vents. Which one type is the correct one. Also, what are the vents for? Thank you in advance.

 

Pictures will help

euclid123, welcome to CL. The driver side vents in the wheel wheel are related to the tow package. See this thread for pictures. It's for a 2013 RX but still applicable.

 

Thank you, kitlz. I will check for the trans cooler if it is indeed there as part of the towing package to confirm.

 

So I believe my car has the towing option. The driver side has vented front slots below the bumper and vented inner liner. The passenger side is not vented. I can also see what I think is the ATF cooling radiator.

 

I dont have the tow package [450H FWD] and the the slots are there on the driver side wheel. You are very right that the slots allow the air flow.
