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 performed by a Honda
technician or other qualified
mechanic.

Maintenance
Replacing a Headlight Bulb
Your vehicle has two bulbs on each
side, four in total. Make sure you are
replacing the bulb that is burned out.
Your vehicle uses halogen headlight
bulbs. When replacing a bulb, handle
it by its plastic case 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.
NOTE: Halogen headlight bulbs get
very hot when lit. Oil, perspiration, or a
scratch on the glass can cause the bulb
to overheat and shatter.
