WARNING
Do not replace the xenon fusion bulbs
yourself:
Replacing the xenon fusion bulbs
yourself is dangerous. Because the
xenon fusion bulbs require high
voltage, you could receive an electric
shock if the bulbs are handled
incorrectly. Consult an Authorized
Mazda Dealer when the replacement is
necessary.

Never touch the glass portion of a
halogen bulb with your bare hands
and always wear eye protection when
handling or working around the bulbs:
When a halogen bulb breaks, it is
dangerous. These bulbs contain
pressurized gas. If one is broken, it will
explode and serious injuries could be
caused by the fl ying glass.
If the glass portion is touched with
bare hands, body oil could cause the
bulb to overheat and explode when lit.

Always keep halogen bulbs out of the
reach of children:
Playing with a halogen bulb is
dangerous. Serious injuries could be
caused by dropping a halogen bulb or
breaking it some other way.
NOTE
 


y To replace the bulb, contact an
Authorized Mazda Dealer.
 


y If the halogen bulb is accidentally
touched, it should be cleaned with
rubbing alcohol before being used.
 


y Use the protective cover and carton for
the replacement bulb to dispose of the
old bulb promptly and out of the reach
of children.
