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 or pull a trailer, 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. 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 Bulb Your vehicle has halogen headlight bulbs. When replacing a bulb, 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. BULB CONNECTOR Halogen headlight 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 the front bulkhead cover (see page 392). 3. Remove the electrical connector from the bulb by pushing on the tab and pulling the connector down. 4. Remove the bulb by turning it about one-quarter turn counterclockwise.
