How to set the car "level" function?

I looked through the FAQ, knowledge base, and did a search, but could not find the directions to reset the car as being "level."

My car still has the HID problem of the headlights pointing about ten feet in front of the car, but today in a parking deck I verified that they do in fact "move." The lights just want to point lower than I believe that they should.

So I am thinking that perhaps the car just doesn't know that it is level anymore.

Thoughts?

 

Oh come on... one of you guys knows the answer!

The Lexus HID auto level uses two, axle mounted sensors - one on the front and one on the rear.

I've only seen and heard of the Prius having the rear sensor.

 

A HA! Found it... I was looking for the wrong term... it's supposed to be "Inclination Setting." I am thinking that the HID auto-level uses this inclination setting as a base-line to compare against the reading from the level unit on the rear axle. Rick, do you know?

From Rick, our Prius Master Tech:

As for the Inclination Sensors,there are 2 located in the Combination Meter. They measure side to side and front to back angle of the Prius.Taking those readings and from the gauge in the tank,the meter knows how many bars to show the driver of fuel in the tank.Who knows why but sometimes the sensors need reset.The procedure is not hard but not done right can make the reading off more.It sometimes takes a couple of tries to get it going in the right pattern of pushes(see below).So here goes;

1. Park on a very level surface, Ready Mode, make sure Odometer reading is showing,then power off.
2. Hold down the Odo/Trip button while going to IGN ON ( foot off brake,not in Ready Mode!).
3. Release/press the Odo/Trip button 3 times in 5 secs. Should be holding the button in at this point.
4. 1st gen: You will see a set of numbers at this point within 5 secs. Release then press Odo/Trip again till you see a "1" which is Reset has begun.When finished,the Odometer will return to normal and you can release the button and power down.
2nd gen: You will also see numbers,but 6 in a row.Release and press again and you will see a set of 5 numbers.After the 3rd digit shows "1", release the button and Odometer should be back to normal.Power down.

For those with TSB acsess, the 1st gen is TSB EL008-03 and for the 2nd gen it is with the fuel tube upate. TSB EL010-04,see page 6.

 

I though so too, until I read the Lexus system uses two sensors.

It was then that it dawned on me that OF COURSE you need a baseline to determine if the car is level to begin with.

I crawled underneath the car and there was the load sensor and the sensing arm attached to the axle.

Now perhaps there is some adjustment that can be set to baseline the load sensor, but I'm thinking that they simply use whatever the inclination setting at "level" is, and then make the adjustments from the reading off the load sensor.

 

Thanks Rick.

I understand the car adjusting the lights as weight is added or removed from the rear of the car, BUT, how do you adjust the HID lamps while the car is empty and level?

How is this baseline established?

When I turn on the car with the HIDs lit, it is obvious that the mechanism is working because the HIDs immediately motor down until they are aimed about 12 feet in front of the car.
