Engine Coolant
▼Inspecting Coolant Level
WA R N I N G
Do not use a match or live flame in the
engine compartment. DO NOT ADD
COOLANT WHEN THE ENGINE IS HOT:
A hot engine is dangerous. If the engine has
been running, parts of the engine
compartment can become very hot. You
could be burned. Carefully inspect the
engine coolant in the coolant reservoir, but
do not open it.
Pull over to a safe location, then switch
the ignition off and make sure the fan is
not running before attempting to work
near the cooling fan:
Working near the cooling fan when it is
running is dangerous. The fan could
continue running indefinitely even if the
engine has stopped and the engine
compartment temperature is high. You
could be hit by the fan and seriously
injured.
Do not remove either cooling
system cap when the engine and radiator
are hot:
When the engine and radiator are hot,
scalding coolant and steam may shoot out
under pressure and cause serious injury.
NOTE
Changing the coolant should be done by
an Authorized Mazda Dealer.
Inspect the antifreeze protection and
coolant level in the coolant reservoir at
least once a year ―at the beginning of the
winter season ―and before traveling where
temperatures may drop below freezing.

Inspect the condition and connections of
all cooling system and heater hoses.
Replace any that are swollen or
deteriorated.

The coolant should be at full in the
radiator and between the F and L marks on
the coolant reservoir when the engine is
cool.

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 (

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.

minerals will concentrate and harden to
form white rings. The rings can damage
your vehicle's finish.
Prevention
It is necessary to wash and wax your
vehicle to preserve its finish according to
the instructions in this section. These steps
should be taken immediately after you find
water marks on your vehicle's finish.
Paint Chipping
Occurrence
Paint chipping occurs when gravel thrown
in the air by another vehicle's tires hits
your vehicle.
How to avoid paint chipping
Keeping a safe distance between you and
the vehicle ahead reduces the chances of
having your paint chipped by flying
gravel.
NOTE
The paint chipping zone varies with the
speed of the vehicle. For example, when
traveling at 90 km/h (56 mph), the paint
chipping zone is 50 m (164 ft).
In low temperatures a vehicle's finish
hardens. This increases the chance of
paint chipping.
Chipped paint can lead to rust forming
on your Mazda. Before this happens,
repair the damage by using Mazda
touch-up paint according to the
instructions in this section. Failure to
repair the affected area could lead to
serious rusting and expensive repairs.

Follow all label and container directions
when using a chemical cleaner or polish.
Read all warnings and cautions.
▼ Maintaining the Finish
Wa s h i n g
CAUTION

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 or wiped with a cloth.
 If the windshield is struck with a hand
or other object from either outside or
inside the vehicle.
Keep hands and scrapers clear of the
windshield when the wiper lever is in the
AUTO position and the ignition is
switched ON as fingers could be pinched
or the wipers and wiper blades damaged
when the wipers activate automatically.
If you are going to clean the windshield,
be sure the wipers are turned off
completely (when it is most likely that the
engine is left running) this is particularly
important when clearing ice and snow.
