engine coolant MAZDA CX5 2023 Owner's Manual

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. 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
Dealer.

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.
▼ 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 7-15.
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.
