2021 MAZDA MODEL CX-5 engine overheat

Brake System
▼Foot Brake
This vehicle has power-assisted brakes
that adjust automati
cally through normal
use.

Should power-assist fail, you can stop by
applying greater force than normal to the
brake pedal. But the distance required to
stop will be greater than usual.
WA R N I N G
Do not coast with the engine stalled or
turned off,
find a safe place to stop:
Coasting with the engine stalled or turned
off is dangerous. Braking will require more
effort, and the brake's power-assist could
be depleted if you pump the brake. This will
cause longer stopping distances or even an
accident.
Shift to a lower gear when going down
steep hills:
Driving with your foot continuously on the
brake pedal or steadily applying the brakes
for long distances is dangerous. This causes
overheated brakes, resulting in longer
stopping distances or even total brake
failure. This could cause loss of vehicle
control and a serious accident. Avoid
continuous application of the brakes.
Dry off brakes that have become wet by
driving slowly, releasing the accelerator
pedal and lightly applying the brakes
several times until the brake performance
returns to normal:
Driving with wet brakes is dangerous.
Increased stopping distance or the vehicle
pulling to one side when braking could
result in a serious accident. Light braking
will indicate whether the brakes have been
affected.
CAUTION
 Do not drive with your foot held on the
brake pedal. Doing so could result in the
following:
 The brake parts will wear out more
quickly.
 The brakes can overheat and adversely
affect brake performance.
 Always depress the brake pedal with the
right foot. Applying the brakes with the
unaccustomed left foot could slow your
reaction time to an emergency situation
resulting in insufficient braking
operation.
Wear shoes appropriate for driving in
order to avoid your shoe contacting the
brake pedal when depressing the
accelerator pedal.

The air conditioner may cause engine
overheating. If the warning light is
illuminated or flashing, turn the air
conditioner off (page 7-18).
NOTE
When maximum cooling is desired, set
the temperature control dial to the
extreme cold position and set the air
intake selector to the recirculated air
position, then turn the fan control dial
fully clockwise.
If warmer air is desired at floor level,
set the mode selector dial at the
position and adjust the temperature
control dial to maintain maximum
comfort.
The air to the floor is warmer than air
to the face (except wh en the temperature
control dial is set at the extreme hot or
cold position).
▼ Ventilation
1. Set the mode selector dial to the
position.
2. Set the air intake selector to the outside air position (indicator light turns off).
3. Set the temperature control dial to the desired position.
4. Set the fan control dial to the desired speed.
▼Windshield Defrosting and
Defogging
1. Set the mode selector dial to the
position.
2. Set the temperature control dial to the desired position.
3. Set the fan control dial to the desired speed.
4. If dehumidified heating is desired, turnon the air conditioner.
WA R N I N G
Do not defog the windshield using the
position with the temperature control set
to the cold position:
Using the
position with the temperature
control set to the cold position is
dangerous as it will cause the outside of the
windshield to fog up. Your vision will be
hampered, which could lead to a serious
accident. Set the temperature control to
the hot or warm position when using the
position.
NOTE
For maximum defrosting, turn on the air
conditioner, set the temperature control
dial to the extreme hot position, and turn
the fan control dial fully clockwise.
If warm air is desired at the floor, set the
mode selector dial to the
position.
In the or position, the air
conditioner is automatically turned on
and the outside air position is
automatically selected to defrost the
windshield. In the
or position, the
outside air position cannot be changed
to the recirculated air position.
▼ Dehumidifying
Operate the air conditioner in cool or cold
weather to help defog the windshield and
side windows.
1. Set the mode selector dial to the
desired position.
2. Set the air intake selector to the outside
air position (indicator light turns off).

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.

If it is low, look for coolant leaks from
the radiator and hoses.

If you find a leak or other damage, or if
coolant is still leaking:
Stop the engine and call an Authorized
Mazda Dealer.

CAUTION
If the engine continues to overheat or
frequently overheats, have the cooling
system inspected. The engine could be
seriously damaged unless repairs are
made. Consult an Authorized Mazda

ing Indication/Warning Light If the warning light illuminates while drivin
g, it indicates a malfunction of the alter‐
nator or of the charging system.
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.
