2010 Acura RL Owner's Manual - Page 465

Lights Headlight Aiming Your vehicle is equipped with an automatic headlight adjusting system that adjusts the vertical angle of the headlights automatically. Refer to page 145 for more information. The headlights were properly aimed when your vehicle was new. If you regularly carry heavy items in the trunk or pull a trailer (if applicable), readjustment may be required. Adjustments should be done by your dealer or another qualified technician. The low beam headlight bulbs are high voltage discharge tube bulbs. High voltage can remain in the circuit even with the light switch off and the key removed. Because of this, you should not attempt to examine or change a low beam headlight bulb yourself. If a low beam headlight bulb fails, take the vehicle to your dealer to have it replaced. 462 2010 RL
