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 FULL and LOW
marks on the coolant reservoir when the
engine is cool.

If it is at or near LOW, add enough coolant
to the coolant reservoir to provide freezing
and corrosion protec tion and to bring the
level to FULL.
Securely tighten the coolant reservoir tank
cap after adding coolant.

Mazda3_8HE9-EA-18K_Edition1 2018-10-17 19:05:10

CAUTION
Radiator coolant will damage paint.
Rinse it off quickly if spilled.
 If the “FL22” mark is shown on or near
the cooling system cap, use of FL-22 is
recommended when replacing engine
coolant. Using engine coolant other than
FL-22 may cause serious damage to the
engine and cooling system.

If the coolant reser voir is empty or new
coolant is required frequently, consult an
Authorized Mazda Dealer.
Brake/Clutch Fluid
▼ Inspecting Brake/Clutch Fluid Level
WA R N I N G
If the brake/clutch fluid level is low, have
the brakes inspected:
A low brake/clutch
fluid level is dangerous.
A low level could indicate brake lining wear
or a brake system leak which could cause
the brakes to fail and lead to an accident.
The brakes and clutch draw fluid from the
same reservoir.
Inspect the fluid level in the reservoir
regularly. It should be kept between the
MAX and MIN lines.
The level normally drops with
accumulated distance, a condition
associated with wear of brake and clutch
linings. If it is exce ssively low, have the
brake/clutch system inspected by an
Authorized Mazda Dealer.

▼Aluminum Wheel Maintenance*
A protective coating is provided over the
aluminum wheels. Special care is needed
to protect t
his coating.
CAUTION
Do not use any detergent other than mild
detergent. Before using any detergent,
verify the ingredients. Otherwise, the
product could discolor or stain the
aluminum wheels.
NOTE
Do not use a wire brush or any abrasive
cleaner, polishing compound, or solvent
on aluminum wheels. They may damage
the coating.
Always use a sponge or soft cloth to
clean the wheels.
Rinse the wheels thoroughly with
lukewarm or cold wate r. Also, be sure to
clean the wheels after driving on dusty
or salted roads to help prevent
corrosion.
Avoid washing your vehicle in an
automatic car wash that uses high-speed
or hard brushes.
▼ Plastic Part Maintenance
When cleaning the plastic lenses of the
lights, do not use gasoline, kerosene,
rectified spirit, paint, thinner, highly
acidic detergents, or strongly alkaline
detergents. Otherwise, these chemical
agents can discolor or damage the
surfaces resulting in a significant loss in
functionality. If plastic parts become
inadvertently exposed to any of these
chemical agents, flush with water
immediately.
If plastic parts such as the bumpers
become inadvertently exposed to
chemical agents or fluids such as
gasoline, oil, engine coolant, or battery
fluid, it could cause discoloration,
staining, or paint peeling. Wipe off any
such chemical agents
or fluids using a
soft cloth immediately.
High water temperature and high water
pressure car washers are available
depending on the type of high pressure
car washer device. If the car washer
nozzle is put too close to the vehicle or
aimed at one area for an extended period
of time, it could deform plastic parts or
damage the paint.
Do not use wax containing compounds
(polish). Otherwise, it could result in
paint damage.
In addition, do not use an electrical or
air tool to apply wax. Otherwise, the
frictional heat generated could result in
deformation of plast ic parts or paint
damage.

Overheating
▼Overheating
If the engine coolant temperature gauge
indicates overheati
ng and the high engine
coolant temperature warning indication is
displayed, the vehicle loses power or you
hear a loud knocking or pinging noise, the
engine is probably too hot.
WA R N I N G
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.
Open the hood ONLY after steam is no
longer escaping from the engine:
Steam from an overheated engine is
dangerous. The escaping steam could
seriously burn you.
If the engine coolant temperature gauge
indicates overheating and the high engine
coolant temperature warning indication is
displayed:

1. Drive safely to the side of the road and
park off the right-of-way.
2. Put a vehicle with an automatic
transmission in park (P), a manual
transmission in neutral.
3. Apply the parking brake.
4. Turn off the air conditioner.
5. Check whether coolant or steam is escaping from the engine
compartment.

If steam is coming from the engine
compartment:
Do not go near the front of the vehicle.
Stop the engine.
Wait until the steam dissipates, then
open the hood and start the engine.

If neither coolant nor steam is
escaping:
Open the hood and idle the engine
until it cools.
CAUTION
If the cooling fan does not operate
while the engine is running, the engine
temperature will increase. Stop the
engine and call an Authorized Mazda
Dealer.
