So I did some searches and also looked at the features listed on the Acura site but didn't find all the answers.

For sure the Acura site lists the perforated leather on the seats and the doors. It also mentions the leather wrapped steering wheel.

In addition to that I am sure (on the 6-speed anyway) that the gear shift knob is wrapped in leather and the shifter skirt is leather.

I am pretty sure the seat panels immediate attached to the preforated leather are also leather. Is that correct?

I do not think the center console arm rest has any leather on it. I also don't think any of the head rests have any leather. Nor is any other surface in the car leather.

Are my assumptions correct?

 

Take a look at this post https://acurazine.com/forums/religion-politics-18/veterans-day-120842/

 

If its anything like the Hoda Accord I owned its all the surfaces you normally come in contact with. The center part of the seat you touch sitting normally, the armrest, the center/front part of the headrest and the center part of the door next to the controls are. I think its the same with my 06.

 

Based on my observation, the leather parts are:
-seating surfaces of the front seats
-seating surfaces of the rear seat, except the middle cushion and seat back including the arm rest.
-front headrests
-perforated door panels and arm rests
-perforated part of the steering wheel

Everything else feels like vinyl to me: center console cover, rear headrests, part of the steering wheel, middle section of the rear seat, the sides and back of the front seats. Shift knob, shifter skirt, e-brake handle and cover feel like vinyl but I'm not 100% sure.

 

-shift knob
-steering wheel (except horn)
-center console cover/arm rest
i think those are all real leather
and these are vinyl
-Ebrake boot
-back of front seats
-parts of back seat

i'm assuming all of these, but i'm not sure

 

Center console cover is definitely not leather, at least on 04 and 05 cars that I have seen. The texture is too smooth and if you press it with your finger, it's doesn't wrinkle or stretch like leather.

 

So...no one really knows anything for sure?

Would it be bad for any vinyl to use leather cleaner and conditioners on it? If I can't tell the difference, I'd probably treat it all like leather - is that bad?

 

This is exactly why I am asking.
I just got my TL last week. And I am putting Lexol on the leather and 303 on most everything else. I don't think lexol will hurt the vinyl, but the lexol doesn't seem to soak in on some surfaces that I had thought was leather. But I don't want to skip treating anything that IS leather. And although 303 lists leather as one of the surfaces it can be used on it just makes it slippery, which is why I prefer the lexol for the leather. Anyway, thanks for the responses so far.

 

That's exactly how you determine if something is vinyl and not leather: vinyl won't absorb leather conditioner. Leather conditioner won't hurt vinyl.

Most leather though will lightly wrinkle and stretch a little if you push it with your finger. Unfortunately, this is hard to do on surfaces with no or little cushioning, like the steering wheel and shifter.

However, you can generally see the difference in vinyl and leather texture. Vinyl generally looks smoother and flawless. Leather usually show some imperfections and coarser texture.
