2020 MAZDA MODEL CX-30 coolant level

Engine Coolant
▼Inspecting Coolant Level
WARNING
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
protection and to bring the level to
FULL.
Securely tighten the coolant reservoir
tank cap after adding coolant.
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 reservoir is empty or new
coolant is required frequently, consult
an Authorized Mazda Dealer.
Brake/Clutch Fluid
▼ Inspecting Brake/Clutch Fluid
Level
WARNING
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 excessively low,
have the brake/clutch system
inspected by an Authorized Mazda
Dealer.

Overheating
▼Overheating
If the engine coolant temperature
gauge indicates overheating 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.
WARNING
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.
6. Make sure the cooling fan is operating, then turn off the engine
after the temperature has
decreased.
7. When cool, check the coolant level.

4. Start the engine and check thewarning light.

If the light remains illuminated even
though the oil level is normal or after
adding oil, stop the engine
immediately and have your vehicle
towed to an Authorized Mazda Dealer.
▼ High Engine Coolant Temperature
Warning Indicat ion
Displays if the engine coolant
temperature has increased excessively.
“Elevated Engine Coolant Temp. Drive
Slowly” displayed
Drive slowly to reduce engine load
until you can find a safe place to stop
the vehicle and wait for the engine to
cool down.
“Excessive Engine Coolant Temp. Stop
the Vehicle in a Safe Location”
displayed
This indicates the possibility of
overheating. Park the vehicle in a safe
place immediately and stop the
engine.
Refer to Overheating on page 7-17.
CAUTION
Do not drive the vehicle with the high
engine coolant temperature warning
light illuminated. Otherwise, it could
result in damage to the engine.
▼ Power Steering Malfunction
Indication/Indicator Light
The message is displayed if the electric
power steering has a malfunction.
If the message is displayed, stop the
vehicle in a safe place and do not
operate the steering wheel. There is no
problem if the indication turns off
when the engine is restarted after
some time has passed. If the indication
displays even after the engine is
restarted, contact an Authorized
Mazda Dealer if the message is
displayed continuously.
NOTE
If the message is displayed, the
power steering will not operate
normally. In this case, the steering
wheel can still be operated,
however, the operation may feel
heavy compared to normal, or the
steering wheel could vibrate when
turning.
Repeatedly jerking the steering
wheel left and right while the vehicle
is stopped or moving extremely
slowly will cause the power steering
system to go into protective mode
which will make the steering feel
heavy, but this does not indicate a
problem. If this occurs, park the
vehicle safely and wait several
minutes for the system to return to
normal.
