I thought it was for the
subwoofer, until I found out there was no subwoofer in the Sequoia.
Then I saw this post at Tundra
Solutions Club Forums - Sequoia:
"The
rear area heater core, air conditioner coils, and blower fan are
located there. The panel itself is the air intake."

panel on Seq."
The Canadian brochure
lists this as a standard feature on the 2003 Sequoia Limited but there
is no information about it in the owner's manual and my sales guy had no
idea what it was. When I asked a service tech he told me it was just an
automatic system that I wouldn't notice until I towed
something. It still didn't explain to me how the whole thing actually worked.
The
following is from Tundra
Solutions Club Forums - Sequoia:
"The
Sequoia does NOT have an airbag or airshock setup and there is no
compressor. I got boned thinking that's what it was and dealer had no
other info either. Essentially it is a set of cargo coil type springs
with a different shock absorber also. Supposedly their is an internal
valve that will allow the shock to "pump" itself up based on
the load (aka Monroe sensa-trac?). I have not tried it towing yet (and
probably won't for a while). I had originally wanted it with plans of
adding HID lights and wanted the truck to stay level if loaded so I
wouldn't blind anybody. I did confirm at 3 different dealers that the
shocks and springs for my vehicle (based on VIN) are different from 98%
of the others. If your thinking your gonna get some kind of air bag type
setup, WRONG, thanks for playing our game(and spending $300). I was
quite disappointed when I found out and told the dealership with a few
colorful detailed words WTF(they took a couple more bucks off and tossed
in a couple goodies) just because they also were "misled". The
positive side is that I feel I got a little better load capacity with
the cargo coil type setup, I'm not concerned with any compressor
breaking down or broken air lines. My friends Expedition has been back
to dealer four times just for these problems." (sic)

More from sequoiasoon
at Edmunds.com:
"I
ordered the QA last year from a dealer in NC after all the NY
dealerships said it was not available (and brought it by to show them
after). I had to wait the 10 weeks also. The system is actually a
different pair of shocks and possibly springs. I went through the
factory service manual and describes exactly how they work. The shock
has extra fluid reservoirs internal with a high pressure / low pressure
setup. It works when you are driving by the action / position of the
internal piston. It does work and I have tried it. You will not notice
it when you put the trailer on (the rear end will drop) but within a
short distance it brings it back up to std ride height. the increased
load forces the piston past an internal valve allowing the extra high
pressure fluid to move the low pressure side where it is needed to
increase the ride height. Once the load is removed, it extends past the
valve in the opposite direction releasing the pressure and letting the
ride height drop to normal. Actually a very smart, reliable system with
out all the compressors and sensors to possibly fail. Many friends have
Expeditions and Navigators and all have had issues with the factory load
leveling. With the Toyota setup I'm not worried. Technically it
"should" be able to be added after just by upgrading to these
shocks. I called the dealer with my VIN and my Aunts VIN (she does not
have QA) and the part #'s were different for the rear shocks but I
forget the price. I was disappointed originally when I found out that it
was not a compressor setup but after reading about and trying it and
knowing everybody elses problems, I'm glad for long term that I have
this setup instead. Long post hope it helps you (and ease your mind)"
