WARNING
Xenon Fusion Bulb Replacement:
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. Do not replace the xenon
fusion bulbs yourself. Consult an
Authorized Mazda Dealer when the
replacement is necessary.
Handling Halogen 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 flying glass.
If the glass portion is touched with
bare hands, body oil could cause the
bulb to overheat and explode when lit.
Never touch the glass portion of the
bulb with your bare hands and always
wear eye protection when handling or
working around halogen bulbs.
Children and Halogen Bulbs:
Playing with a halogen bulb is
dangerous. Serious injuries could be
caused by dropping a halogen bulb or
breaking it some other way.
Always keep halogen bulbs out of the
reach of children.
