2009 Acura TL Owner's Manual - Page 559

Main Menu Table Of Contents Lights Headlight Aiming The headlights were properly aimed when your vehicle was new. If you regularly carry heavy items in the trunk, readjustment may be required. Adjustments should be done by your dealer or another qualified technician. Low Beam Headlight Bulb Replacement The low beam headlight bulbs are a type of high voltage discharge tube. High voltage can remain in the circuit even with the light switch off and the key removed (or the vehicle is in VEHICLE OFF (LOCK) mode on models with keyless access system). 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. Replacing a High Beam Headlight/Daytime Running Light Bulb Your vehicle has halogen high beam headlight bulbs which are also used for the daytime running light. Handle it by its base and protect the glass from contact with your skin or hard objects. If you touch the glass, clean it with denatured alcohol and a clean cloth. HOLDING CLIP Halogen bulbs get very hot when lit. Oil, perspiration, or a scratch on the glass can cause the bulb to overheat and shatter. 1. Open the hood. 2. Remove all engine compartment covers (see page 546 ). If you are replacing the bulb on the driver's side, remove the three holding clips with a flat-tipped screwdriver. Then remove the upper part of the air intake duct by pulling it straight up. 556 2009 TL
