For the proper type of replacement
bulbs, see
.
For any bulb changing procedure
not listed in this section, contact
your dealer/retailer.
Halogen bulbs have pressurized
gas inside and can burst if you
drop or scratch the bulb. You or
others could be injured. Be sure
to read and follow the instructions
on the bulb package.
The low beam high intensity
discharge lighting system
operates at a very high voltage.
If you try to service any of the
system components, you could be
seriously injured. Have your
dealer/retailer or a qualified
technician service them.
The up-level vehicle has HID
headlamps. The park lamp function
is also a function of the HID
headlamp. After an HID headlamp
bulb has been replaced, the beam
might be a slightly different shade
than it was originally. This is normal.
To replace fog lamp bulb:
1. Pull out the push-pins located on
the underside of the protection
shield to remove the shield.
2. Reach up behind the front
bumper area from under the
vehicle to access the lamp
housing.
3. Remove the electrical connector
from the bulb by lifting the two
plastic clips.
