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.

Replenishment
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.
NOTE
When adding DEF during low
temperatures (
