HONDA 2010 Ridgeline - Manual (Page 340)

The headlights were properly aimed
when your vehicle was new. If you
regularly carry heavy items on the
pickup bed or pull a trailer,
readjustment may be required.
Adjustments should be done by your
dealer or other qualified technician. 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. The timing belt should be replaced
at the intervals shown in the
maintenance minder schedule.
Replace the timing belt every 60,000
miles (U.S.) or every 100,000 km
(Canada) if you regularly drive your
vehicle in any of the following
conditions:
In very high temperatures
(over 110°F, 43°C).
In very low temperatures
(under
20°F, 29°C).
Frequently towing a trailer.

Halogen headlight bulbs get very hot
when lit. Oil, perspiration, or a scratch
on the glass can cause the bulb to
overheat and shatter.
