engine MAZDA MODEL CX-9 2020 Owners Manual (in English)

Starting a Flooded Engine
If the engine fails to start, 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 push button start. 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.
Push-Starting
Do not push-start your Mazda.
WA R N I N G
Never tow a vehicle to start it:
Towing a vehicle to start it is dangerous.
The vehicle being towed could surge
forward when its engine starts, causing the
2 vehicles to collide. The occupants could
be injured.
NOTE
You cannot start a vehicle with an
automatic transaxle by pushing it.

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.

CX-9_8HT8-EA-19I_Edition2_old 2019-9-24 13:14:55

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.

Coolant reservoir
Cooling fan
If you find no problems, the engine is
cool, and no leaks are obvious:
Carefully add coolant as required (page
6-24).
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.
