Does anybody have any idea how to adjust the headlights up and down on an 04 Sienna. I was towing a trailer the other night and I was being flashed with high beams from other drivers. I found what I think is an adjuster but it looks like it's the side to side adjuster. Thanks for any help.

Were you towing a heavy load? It may just be that the weight of the trailer pulled down on the back end enough to cause the front end to come up just enough to cause the lights to bother the on coming traffic.

How do you like your Sienna, we will probably be purchasing one in the very near future (which is why I was checking this board out).

The trailer hitch (for the 2004 Sienna installed at Toyota dealership) scrapes almost every time we pull in or out of a parking lot (with a medium to small dip), or go over speedbumps etc. It happens intermitently when the only person in the van is the driver, and happens all the time if we have passengers. We cringe at the thought of trying to pull pull a loaded trailer, with the van loaded. It seems to me that the hitch we have should not have been offered as an accessory for this vehicle. We're waiting to see how our dealership plans to rectify this problem.
Does anyone else has a similar problem?

On our 04, we have a headlight adjuster next to the steering wheel. Its a roller/wheel type adjuster from 0 to 5 (0 being neutral, and 5 being down about 5 degrees). I'm not sure if this is on all models but we have the HID lights...

hope that helps

Well, you have to remember that the XLE Limited model is the only 04' model to have the adjusting headlights. Its next to the steering wheel if you have the XLE Limited model. I rarely use it, since I don't find the need.
