Start MAZDA CX90 2024 Manual PDF

Starting a Flooded Engine
If the engine stops unexpectedly, it
may be flooded (excessive fuel in the
engine).

Follow this procedure:

1. If the engine does not start within 5seconds on the first try, wait 10
seconds and try again.
2. Make sure the parking brake is on.
3. Depress the accelerator all the way
and hold it there.
4. Depress the brake pedal, then press the power switch. If the engine
starts, release the accelerator
immediately because the engine
will suddenly rev up.
5. If the engine fails to start, crank it without depressing the accelerator.

If the engine still does not start using
the previous procedure, have your
vehicle inspected by an Authorized
Mazda Dealer.

Ta k i n g A c t i o n w i t hOverheating
If the engine coolant temperature
gauge indicates overheating and the
high engine coolant temperature
warning light 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 vehicle power 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.

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.

Do not start the engine or shake
the vehicle while it is jacked up.
Starting the engine or shaking the
vehicle while it is jacked up is
dangerous as it could cause the
vehicle to fall off the jack resulting
in an accident.
Never go under the vehicle while it
is jacked up.
Going under the vehicle while it is
jacked up is dangerous as it could
result in death or serious injury if
the vehicle were to fall off the jack.
8. Remove the lug nuts by turning them counterclockwise; then
remove the wheel and center cap.
Locking Lug Nuts
If your Mazda is equipped with the
optional antitheft wheel lug nuts, a
special key must be used to unlock the
locking lug nut for each wheel. The key
is stored in the glove compartment,
center console storage, storage box, or
trunk. Register the key and lug nuts
with the lock manufacturer by filling
out the registration card and mailing it
in using the accompanying envelope. If
the key is lost, consult an Authorized
Mazda Dealer or use the lock
manufacturer’s order form to order a
new key.
Antitheft wheel lug nuts cannot be
installed on a steel wheel spare tire.
When installing a temporary spare tire,
use one of the original lug nuts in place
of the locking lug nut. The original lug
nuts are stored inside your Mazda.
1. Antitheft lug nut
2. Special key
To remove an antitheft lug nut
1. Obtain the special key for the antitheft lug nut.
2. Place the special key on top of the antitheft lug nut, and be sure to
hold the key square to it. If you
hold the key at an angle, you may
damage both key and nut. Do not
use a power impact wrench.
3. Place the lug wrench on top of the key and apply pressure. Turn the
wrench counterclockwise.
To install the antitheft lug nut
