2021 MAZDA MODEL CX-5 coolant level

Owner Maintenance Precautions
The owner or a qualified service technician should make these vehicle inspections at the
indicated intervals to ensure safe and dependable operation.

Bring any problem to the attention of an Authorized Mazda Dealer or qualified service
technician as soon as possible.
When Refueling
Brake fluid level (page 6-28)
Engine coolant level (page 6-26)
Engine oil level (page 6-24)
Washer fluid level (page 6-28)
At Least Monthly
Tire inflation pressures (page 6-43)
At Least Twice a Year (For Example, Every Spring and Fall)
You can do the following sche duled maintenance items if you have some mechanical ability
and a few basic tools and if you closely follow the directions in this manual.
Engine coolant (page 6-26)
Engine oil (page 6-22)

Improper or incomplete service may result in problems. This section gives instructions only
for items that are easy to perform.

As explained in the Introduction (page 6-2), several procedures can be done only by a
qualified service technician with special tools.

Improper owner maintenance during the warranty period may affect warranty coverage.
Refer to Introduction (page 6-2) for owner's re sponsibility in protecting your investment.
For details, read the separate Mazda Warranty statement provided with the vehicle. If you
are unsure about any servicing or maintenance procedure, have it done by an Authorized
Mazda Dealer.

There are strict environmental laws regarding the disposal of waste oil and fluids. Please
dispose of your waste properly and with due regard to the environment.

We recommend that you entrust the oil and flu id changes of your vehicle to an Authorized
Mazda Dealer.

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.

SKYACTIV-D 2.2

If it is at or near L, add enough coolant to
the coolant reservoir to provide freezing
and corrosion protection and to bring the
level to F.
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.

Overheating
If the temperature gauge indicates
overheating or the high engine coolant
temperature warning light turns on, 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 temperature gauge indicates
overheating or the high engine coolant
temperature warning light turns on:

1. Drive safely to the side of the road and
park off the right-of-way.
2. Shift into park (P).
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.

Drive to the side of the road and park off the right-of-way. Consult an Authorized
Mazda Dealer.
CAUTION
Do not continue driving when the charging system warning light is illuminated be‐
cause the engine could stop unexpectedly.
Engine Oil Warning Light This warning light indicates
low engine oil pressure.
CAUTION
Do not run the engine if the oil pressure is low. Otherwise, it could result in extensive
engine damage.
If the light illuminates or the warni ng indication is displayed while driving:
1. Drive to the side of the road and park off the right-of-way on level ground.
2. Turn off the engine and wait 5 minutes for the oil to drain ba ck into the oil pan.
3. Inspect the engine oil level (page 6-24). If it's low, add the appropriate amount of
engine oil while being careful not to overfill.
CAUTION
Do not run the engine if the oil level is low. Otherwise, it could result in extensive
engine damage.
4. Start the engine and check the warning 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.
(Red)
High Engine Coolant
Temperature Warning Indication/Warning Light The light flashes when the en
gine coolant temperature is extremely high, and illumi‐
nates when the engine coolant temperature increases further.
Handling Procedure
Flashing light
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.
Illuminated light
This indicates the possibility of overheating. Park the vehicle in a safe place immedi ‐
ately and stop the engine.
Refer to Overheating on page 7-18.
CAUTION
Do not drive the vehicle with the high engi ne coolant temperature warning light illumi‐
nated. Otherwise, it could resu lt in damage to the engine.
