auto leveling head lights

buzzard bill · 09-09-2006, 07:38 AM

I have two 2005 Prius with auto leveling head lights. My question is how do they work?? (motors, gravity, electric, etc)

Thanks,
Bill

Motors. There is a sensor in the back of the car that measures how much the suspension is compressed, which then turns leveling motors in the light assemblies.

If I recall correctly, the sensor can be seen on the left rear suspension. It's a part that has failed for a few owners BTW.

Good info. I've looked the system over in the on-line service manuals at techinfo.toyota.com. You can test the system easily by turning the lights on while close to a wall (inside of garage works well). Open the rear hatch, and kneel at the back of the cargo compartment. Watch the light pattern. First it will rise as your weight compresses the rear suspension. About five seconds later, the system will re-aim them to the correct level. Then get out, and watch the lights dip. Another five seconds, and back to normal.
