Engine Emissions Inside Car?

[douglasmiami]

Now that the weather in Miami has cooled all the way down to 80 degrees, I've been using my vent more in my '99 RX 300 as opposed to running AC unit. But I've noticed an exhaust emission smell inside the cabin when I'm idling at a stop. Since I'm venting from the outside, is this simply the car in front of me, or could it be my engine emission that is leaking inside?

Thanks.

I believe it takes the air in from the rear bumper (the crack b/t the bumper and the car) on the driver's side. Turn it on "outside air" and go out and listen; you'll hear it sucking the air in.

I don't know if this helps.

I don't think you'll see any car drawing the air intake for the ventilation and heating system from the rear of the car! In fact, you're warned not to drive with the hatch open for just that reason. The intake is just below the windshield, and the same air is drawn for vent, heat, or a/c. Just make sure that area is clear of debris.
