▼Lane-Change Signals
Move the lever halfway toward the
direction of the lane change―until the

will return to the off position when
released.
▼Three-Flash Turn Signal
After releasing the turn signal lever, the
turn signal indicator flashes three times.
The operation can be cancelled by moving
the lever in the direction opposite to which
it was operated.
NOTE
The three-flash turn signal function can be
switched to operable/inoperable using the
personalization function.

Windshield Wipers and
Wa s h e r
The ignition must be switched ON to use
the wipers.
WA R N I N G
Use only windshield washer fluid or plain
water in the reservoir:
Using radiator antifreeze as washer fluid is
dangerous. If sprayed on the windshield, it
will dirty the windshield, affect your
visibility, and could result in an accident.
Only use windshield washer fluid mixed
with anti-freeze protection in freezing
weather conditions:
Using windshield washer fluid without
anti-freeze protection in freezing weather
conditions is dangerous as it could freeze
on the windshield and block your vision
which could cause an accident. In addition,
make sure the windshield is sufficiently
warmed using the defroster before
spraying the washer fluid.

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.
