Do not put DEF into a
different container.
There may be foreign matter in the
container. If DEF containing foreign
matter is used, it could cause a problem
with the SCR system. In addition,
changing containers is dangerous
because it increases the risk of accidental
ingestion.
NOTE
DEF is a colorless, transparent,
odorless, and nonpoisonous solution
(urea: 32.5 %, aqueous solution
(AUS32)).
Store DEF in a cool, dark place.
DEF freezes at –11 °C (12 °F), however,
when the temperature increases, the
DEF returns to its original condition.
When opening the container, there may
be a smell of ammonia. Open the
container in a well-ventilated area.
If DEF gets on your hands, wash them
with running water immediately.

CAUTION

Use a Mazda genuine product or a
product conforming to ISO22241-1 for
DEF. If incompatible DEF is used, the
Selective Catalytic Reduction (SCR)
system may not operate normally. For
the recommended DEF, consult the
nearest Authorized Mazda Dealer.
 Do not dilute DEF with water. If diluted
DEF is used, it could cause a problem
with the SCR system or damage it.
Do not add any
fluid other than DEF to
the urea tank. If any fluid other than DEF
is added, it could cause a problem with
the SCR system or damage it. Do not
switch the ignition ON, and contact an
Authorized Mazda Dealer.
 When adding DEF, use a bottle with an
anti-spill nozzle. If a bottle without an
anti-spill nozzle or a commercial
dispenser at a gasoline station is used, it
could cause leakage or the DEF to spray
out.
 Do not overfill the DEF. If the DEF is
overfilled, it may freeze during cold
temperatures (–11°C (12 °F) or less).
When urea freezes, it expands and could
cause tank breakage. Always use a bottle
with an auto-stop function and stop
adding fluid when the auto-stop
function operates.
