Hi,

The battery on my wife's 07 RX350 was replaced in late November. She was advised to drive it regularly so as not to run it down due to inactivity.

Knowing she'd be out of town for a month, we figured we'd just disconnect the battery like we'd done with our other cars. (Negative post was disconnected)

She connected the battery today and it started just fine. She had to reset the seats, radio, steering column, etc.

She noticed that the only the driver side window goes up and down. None of the other three windows work. She hasn't checked the moonroof.

She also noticed that when you turn off the car, it sounds almost like a jet engine that whines/winds down vs. a simple quick engine cutoff.

Questions:
- Is there a reset for the windows?
- Is the whining wind down sound the engine makes upon turning it off require some sort of a "reset" also? Done by the dealer perhaps?

Your help would be appreciated.

Thanks,
eagle

There is a dealer checklist of things to reset when power has been removed. For the windows I believe you need to go to each window and hold the button until the window goes all the way down and back up. For the roof you need to hold the tilt button until the roof tilts, closes, slides back and then slides forward then release. The easiest way to deal with long term storage is to buy a battery minder device. These can be had for as little as $25 at times and will keep your battery in good health.

You might also have lost some of your specific custom settings by removing the power, I can't recall if that is saved in non-volatile memory.

This process has also cleared your car's driving style memory. The vehicle learns from your driving and fine tunes the way it drives based on that history.

To reset the windows after disconnecting the battery:

Go to the local switch at each window (not from the driver's door) and manually run the window full down then full up. This must be done at each door as each window is individually manually reset by doing this. The windows will then operate automatically from both the local switch on each door and the remote switches on the driver's door.

As soon as I figure out how to reset the moon roof I will post direction on that too.

I disconnected the battery in an unsuccessful attempt to get a Hybrid 5.1/7.1 Nav disc to work. We later noticed the windows and roof were not working either properly or at all. We were just going to wait to the 1000 mile service in a few weeks to get this resolved but now that I know what caused the problem I will simply do the resetting myself.

I just managed to reset my roof so it works correctly. Unfortunately, I am not exactly sure what I did but it had something to do with manually running it full open and full closed along with some manipulation of the tilt switch.

Thanks.

Going to each window and running a cycle of up and down and holding the button a few seconds longer after it is all the way up worked.

Appreciate all the help.

Disconnecting the battery is a pain, and not near as good for the battery as a trickle charger, the most popular kind being the "Battery Tender." This charges the battery with a small charge and, to prevent damage from overcharging, senses a full charge and turns off the charging until needed. They are designed for long term storage of autos, motorcycles, etc.
They are not expensive, and come with a connector that attaches tightly to the battery contacts and terminates in a quick disconnect plug that you can leave accessible by the wipers or out the grill, etc.
For the situation you describe, this would be highly recommended.

Plus 2 on the above ^^.

Great battery saver. It is a pain to re-initialize everything.
