MAZDA MODEL 3 4-DOOR 2018 Owners Manual

WA R N I N G
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 flying 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.
CAUTION
When removing the lens or lamp unit using
a flathead screwdriver, make sure that the
flathead screwdriver does not contact the
interior terminal. If the flathead screwdriver
contacts the terminal, a short circuit may
occur.
NOTE
To replace the bulb, contact an
Authorized Mazda Dealer.
If the halogen bulb is accidentally
touched, it should be cleaned with
rubbing alcohol before being used.
Use the protective cover and carton for
the replacement bulb to dispose of the
old bulb promptly and out of the reach
of children.
