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.
▼ Diesel Exhaust Fluid (DEF)
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 (

Replenishment of DEF by an Authorized
Mazda Dealer is recommended. If you
want to replenish the DEF yourself,
follow the replenishment procedure
below.
Replenishment Procedure

CAUTION
If too much DEF is added, the SCR
system might display a warning.
Contact an Authorized Mazda Dealer if
a warning is displayed. If the warning
remains displayed, the urea tank may
have a problem or it may be damaged.
NOTE
If excessive force is applied when
pressing in the bottom of the bottle,
the bottle or the DEF filler port may
be damaged.
When the urea tank is full, stop
adding DEF because the flow from
the bottle slows down by the bottle's
auto-stop function. If you continue
adding DEF, the urea tank will
overfill.
7. Press in the bottom of the bottle straight and add DEF.

8. Remove the bottle in the reverse order
of the insertion. At this time, be careful
of DEF dripping from the bottle.
9. Tighten the cap of the DEF filler port
until you hear two or more click
sounds.
10. Switch the ignition ON once.
11. Check the followi ng while the vehicle
is stopped.
No DEF level warn ing indication is
displayed on the multi-information
display.
The DEF level (%) indication on the
multi-information display shows an
increase.
(Instrument cluster (Type A))

Wiper Blades
CAUTION
Hot waxes applied by automatic car
washers have been known to affect the
wiper's ability to clean windows.
To prevent damage to the wiper blades,
do not use gasoline, kerosene, paint
thinner, or other solvents on or near
them.
When the wiper lever is in the AUTO
position and the ignition is switched ON,
the wipers may move automatically in
the following cases:
If the windshield above the rain sensor
is touched.
If the windshield above the rain sensor
is wiped with a cloth.
If the windshield is struck with a hand
or other object.
If the rain sensor is struck with a hand
or other object from inside the vehicle.
Be careful not to pinch hands or fingers
as it may cause injury, or damage the
wipers. When washing or servicing the
vehicle, make sure the wiper lever is in
the OFF position.
Contamination of either the windshield or
the blades with foreign matter can reduce
wiper effectiveness. Common sources are
insects, tree sap, and hot wax treatments
used by some commercial car washes.
If the blades are not wiping properly, clean
the window and blades with a good
cleaner or mild detergent; then rinse
thoroughly with clean water. Repeat if
necessary.
▼ Replacing Windshield Wiper Blades
When the wipers no longer clean well, the
blades are probably worn or cracked.
Replace them.
CAUTION
To prevent damage to the wiper arms
and other components, do not try to
sweep the wiper arm by hand.
Do not bend the blade rubber
unnecessarily when replacing it.
Otherwise, the metal stiffener in the
blade may deform and the windshield
wiper operation may be adversely
affected.
NOTE
When raising both windshield wiper arms,
raise the driver's side wiper arm first.
When lowering the wiper arms, slowly
lower the wiper arm fr om the passenger's
side first while supporting it with your
hand. Forcefully lowering the wiper arms
could damage the wiper arm and blade,
and may scratch or crack the windshield.
Replace the wiper blades using the
following procedure.
1. Raise the wiper arm.
CAUTION
To prevent damage to the windshield
let the wiper arm down easily, do not
let it slap down on the windshield.
2. Slide the blade component in the direction of the arrow while pressing

Battery
WARNING
Wash hands after handling the battery and related accessories:
Battery posts, terminals and related accessories contain lead and lead compounds, chemicals
known to the State of California to cause cancer and reproductive harm.
Read the following precautions carefully before using the battery or inspecting to
ensure safe and correct handling:
Always wear eye protection when working near the battery:
Working without eye protection is dangerous. Battery fluid contains SULFURIC ACID which
could cause blindness if splashed into your ey es. Also, hydrogen gas produced during normal
battery operation, could ignite and cause the battery to explode.
Wear eye protection and protective gloves to prevent contact with battery fluid:
Spilled battery fluid is dangerous.
Battery fluid contains SULFURIC ACID which could ca use serious injuries if it gets in eyes, or on
the skin or clothing. If this happens, immediately
flush your eyes with water for 15 minutes or
wash your skin thoroughly and get medical attention.
Always keep batteries out of the reach of children:
Allowing children to play near batteries is dangerous. Battery
fluid could cause serious injuries
if it gets in the eyes or on the skin.
Keep flames and sparks away from open battery cells and do not allow metal tools to
contact the positive (
) or negative () terminal of the battery when working near a battery.
Do not allow the positive (
) terminal to contact the vehicle body:
Flames and sparks near open battery cells are da ngerous. Hydrogen gas, produced during normal
battery operation, could ignite and cause the battery to explode. An exploding battery can cause serious
burns and injuries. Keep all flames including cigarettes and sparks away from open battery cells.
