Just bought this IS350 from my brother and want to give it a deep clean. I'd like to detach the front driver seat to access all the crevices.

I've read another post and have a pretty good idea what to do for this to be accomplished. That being said, some of the posts mentioned being extra careful when reattaching the seats. Like getting the exact torque for each bolt is mandatory.

Are there sensors for these bolts or something? That might cause an issue if the proper torque is not applied? Or were they simply referencing potential stripped bolts? If there are sensors or something else that might cause serious issues, what tools would I need to buy in order to check the torque level?

Lastly, is there an easier way to go about doing this altogether? I just want to clean under the driver seat and in between the center console.

Thanks

 

There are no sensors for the seat bolts. It is, however, a good idea to torque them down correctly because you don't want the seat coming loose in case of an accident.

You'll likely see that the seat bolts have Sharpie marks on them. I would take note of the position of the Sharpie marks and make sure that when you tighten down the seat, that the Sharpie mark is back in the same, original location. The marks are placed there in the factory and it allows one to quickly determine if the seat bolts have come loose over ownership of the car.

Here's an example of what I'm talking about. It's not a car seat but marking critical fasteners is common:

 

I would not worry about bolts or exact torque. The hardware is not going to strip. I would disconnect the battery tho! At some level seat power is hot so, battery is the first thing I do.
Reverse order when done. I'm not sure where you read crazy stuff about bolt sensors... Forget about that...

 

This reminds me of when I had to take out the passenger seat in my LS400 a few years ago. I got 3 of the bolts back in, but I could never get the right front corner seat bolt back into the threaded hole. It just didn't want to thread in correctly for some reason. It's been a few years, and I think that the hardware might have been left/right specific? Who knows. I was the first, and last, person to take out that bolt. I probably just did something dumb.

 

Seats and seat belts use high grade hardware. You can still cross thread them, make burrs, drive them in at bad angles but generally speaking, they will not strip easily. Most will be grade 12 or something like that and have high anti-corrosion properties with good washers and all that. Death by seat or belt failure is highly frowned upon.

The trick with seats is to start all bolts loosely, and then tighten them. If that can't be done, loosen the bracket at the seat level until it all aligns.
