Bulb Replacement
For the proper type of replacement
bulbs, seeReplacement Bulbs on
page 10‑39.
For any bulb‐changing procedure
not listed in this section, contact
your dealer.
Halogen Bulbs
{WARNING
Halogen bulbs have pressurized

drop or scratch the bulb. You or
others could be injured. Be sure
to read and follow the instructions
on the bulb package.
High Intensity Discharge

shield to remove the shield.
2. Reach up behind the front bumper area from under the
vehicle to access the lamp
