Window Tinting Confusion
I'm working on a MY25 GLE 580 build, and I would like to spec the same tinting as this vehicle received. Here's the data I've collected, some from test drives I did two days ago, and not all of it reconciles:
1. From MBWorld, posters have said the uniform tinting (exclusive of the windshield) is NOT a feature of the DC5 Acoustic Comfort Package, which I am including in my build regardless.
2. My CA said this 350 came from the factory like that.
3. He also said -- and I believe that I observed it to be true on other vehicles there, can't be 100% certain, once he pointed it out -- that tinting darkness is a function of interior color: lighter interiors get lighter tinting, darker interiors get darker tinting.
4. BUT... this 350 appears to be Twilight Blue over Macchiato... the lightest color interior on offer... and this uniform tinting is the darkest shade I observed on any vehicle there that day.
So... I'm unable to reconcile points 2, 3, and 4.
What I do know is that I would really like my 580 to come from the factory, versus using an aftermarket solution, with first row tinting to match that of the rest of the vehicle, exclusive of the windshield, for both aesthetic and functional reasons.
Thanks in advance for any insights.

Tint does become darker if the interior is darker. It's all about light that's being let in. Also if you have a black headliner the tint becomes darker. Samething if you have a pano roof vs don't. I have a panoroof, but I have a black interior. My windshield isn't tinted.
Sunroof closed in the first photo, sunroof open in the second one. Only the two front windows have been tinted by my tinter.

Rear windows are at a 15% tint, at least on the 2024 GLE. I used a meter on my factory tinted rear windows and it let in about 13.36% light.
I had my front windows done with 20% and I can notice they are lighter. (I also have a pano roof and light interior). I'm actually going tomorrow to get the 20% removed and replaced with 15% on the front windows.




If front and rear are equal, the front can still look lighter with incoming light from windshield and with the beige interior.
I forgot what my windows measured, but if I remember correctly 17% rear and high 80s% front (CA law says must be >88% so it may be been 88%). I told installer I want them to match. I chose the second highest ceramic offering from SunTek (the highest one was way more expensive and seemed pointless with the IR glass) that comes in 20% or 30%. Installer told me the % on the meter after the install won't match between the front and rear, said I can choose either very slightly darker or slightly lighter for the front vs the rear. I chose slightly lighter option, didn't want windows to be too dark. He also had the highest end Suntek offering came in 25% which would make a closer match according to a meter.
In real life, I can't tell the difference.
edit: my 20% or 30% vs. ideal match 25% numbers might be off, but the idea is the same.

The CA also made it sound like, not that the tinting dynamically changes transmission %, rather, that the factory installs windows with different transmission percentages based on the color of the interior. That sounded squirrelly to me. In hindsight, the differences I perceived were likely due to the factors you mentioned.
@taphil Thanks, as always. Great stuff.

@graffixnyc Thanks. That is my understanding as well... which is why the CA's initial statement that that 350 came from the factory that way didn't make sense to me. I'd hoped that was the case, but, my take away at this point is that it is not

In NJ, they only do emissions inspections and it's not required to do a safety inspection like in NY, so they don't check/care if your windows are tinted when you go for inspection.

So I’ve established that to get my front row to match the factory second row, it’s an aftermarket solution. Got that now.
But I’m curious about the ease with which it can be safely changed/replaced, as @graffixnyc described, without damaging the factory-installed treatments: I plan to order the DC5 Acoustic Comfort Package on my GLE 580, which is described in the DOG as “Increased Cabin Insulation, Windshield with Infrared-Reflecting film, Side Windows with Acoustic Infrared-Absorbing Film.”
Any issues with applying aftermarket tinting on top of this other films? If the tinting film ever needs to be removed, will doing so somehow damage this other film underneath, and or void factory warranty?

I'm originally from NY. The one worse thing about tint in NY is that they will fail you for inspection if your windows are tinted. Unless, you find someone that is willing to pass it anyway. Which isn't that difficult. Some shops are pains about it, some don't care.
In NJ, they only do emissions inspections and it's not required to do a safety inspection like in NY, so they don't check/care if your windows are tinted when you go for inspection.

So if you put 20% on your front windows, the actual percentage will be around 14%.
I just had my S580 done in Sun Tek CIR 40%, which actually has 44% light transmission, so my net VLT is now 30.8, it would still fail if I got stopped.




Go to a reputable car window tint shop. I found mine on yelp. They’ll have options for different film types and darkness. They’ll have a meter to measure stock glass. They can place samples on the window and measure % and you can look for yourself. Besides matching tint darkness/%, the other problem is matching tone. The stock rear windows are slightly bluish. The first ceramic Suntek tint I got 7y ago on my GLC was slightly hazy and slightly greenish, but ceramic was kinda new at the time. Subsequent Suntek ceramic films I got on my newer cars are crystal clear and neutral but doesn’t exactly match the bluish rear windows. You don’t notice it unless you’re inside the car and carefully looking out both front and rear windows at the same time to compare.
One of my GLE window tints had a spec of dust in the install that I found a day after, the shop redid it for free a week later.
If you want to boggle your mind, you can research 3M films vs competitors.

My tint guy removed it and replaced it for free which was a nice surprise as I was expecting to have to pay for it again. He took the blame for it since I originally went in asking for the front tint to match the factory tint on the back windows and he just assumed it was 20% without checking with the meter first.

When you put 30% tint on 70% factory tinted windows you wind up with windows that are 21% tint. They let 21% of light through.

OP is confused and I'm sure the other guys post just confused him even more.
