engine MAZDA MODEL CX-9 2021 Owner's Manual

Modification and Add-OnEquipment
Mazda cannot guarantee the immobilizer
and the theft-deterrent systems' operation
if the system has been modified or if any
add-on equipment has been installed.
CAUTION
To avoid damage to the vehicle, do not
modify the system or install any add-on
equipment to the immobilizer and the
theft-deterrent systems or the vehicle.
Immobilizer System
The immobilizer system allows the engine
to start only with a key the system
recognizes.

If someone attempts to start the engine
with an unrecognized ke y, the engine will
not start, thereby helping to prevent
vehicle theft.
If you have a problem with the
immobilizer system or the key, consult an
Authorized Mazda Dealer.
CAUTION
 Radio equipment like this is governed by
laws in the United States.
Changes or modifications not expressly
approved by the party responsible for
compliance could void the user's
authority to operate the equipment.
 To avoid damage to the key, do not:
 Drop the key.
 Get the key wet.
 Expose the key to any kind of magnetic
field.
 Expose the key to high temperatures
on places such as the dashboard or
hood, under direct sunlight.
 If the engine does not start with the
correct key, and the security indicator
light keeps illuminating or flashing, the
system may have a malfunction. Consult
an Authorized Mazda Dealer.

NOTE
The keys carry a unique electronic code.
For this reason, and to assure your
safety, obtaining a replacement key
requires some waiting time. They are
only available through an Authorized
Mazda Dealer.
Always keep a spare key in case one is
lost. If a key is lost, consult an
Authorized Mazda Dealer as soon as
possible.
If you lose a key, an Authorized Mazda
Dealer, will reset the electronic codes of
your remaining keys and immobilizer
system. Bring all the remaining keys to
the Authorized Mazda Dealer to reset.
Starting the vehicle with a key that has
not been reset is not possible.
▼Operation
NOTE
The engine may not start and security
indicator light may illuminate or flash if
the key is placed in an area where it is
difficult for the system to detect the
signal, such as on the dashboard or in
the glove compartment. Move the key to
a location within
the signal range,
switch the ignition off, and then restart
the engine.
Signals from a TV or radio station, or
from a transceiver or mobile telephone
could interfere with your immobilizer
system. If you are using the proper key
and the engine fails to start, check the
security indicator light.
Arming
The system is armed when the ignition is
switched from ON to off.
The security indicator light in the
instrument cluster flashes every 2 seconds
until the system is disarmed.

Disarming
The system is disarmed when the ignition
is switched ON with the correct
programmed key. The security indicator
light illuminates for about 3 seconds and
then turns off. If the engine does not start
with the correct key, and the security
indicator light remains illuminated or
flashing, try the following:
Make sure the key is within the
operational range for signal transmission.
Switch the ignition off, and then restart the
engine. If the engine does not start after 3
or more tries, contact an Authorized
Mazda Dealer.
NOTE
If the security indicator light flashes
continuously while you are driving, do
not shut off the engine. Go to an
Authorized Mazda Dealer, and have it
checked. If the engine is shut off while
the indicator light is flashing, you will
not be able to restart it.
Because the electronic codes are reset
when the immobilizer system is repaired,
the keys are needed. Make sure to bring
all the keys to an Authorized Mazda
Dealer, so that they can be programmed.

Break-In Period
No special break-in is necessary, but a few
precautions in the first 1,000 km (600
miles) may add to the performance,
economy, and life of the vehicle.
Do not race the engine.
Do not maintain one constant speed,
either slow or fast, for a long period of
time.
Do not drive constantly at full-throttle or
high engine rpm for extended periods of
time.
Avoid unnecessary hard stops.
Avoid full-throttle starts.
Do not tow a trailer.
Saving Fuel and Protectionof the Environment
How you operate your Mazda determines
how far it will travel on a tank of fuel. Use
these suggestions to help save fuel and
reduce CO
2.
Avoid long warm-ups. Once the engine
runs smoothly, begin driving.
Avoid fast starts.
Drive at lower speeds.
Anticipate when to apply the brakes
(avoid sudden braking).
Follow the maintenance schedule (page
6-4) and have an Authorized Mazda
Dealer perform inspections and
servicing.
Use the air conditioner only when
necessary.
Slow down on rough roads.
Keep the tires properly inflated.
Do not carry unnecessary weight.
Do not rest your foot on the brake pedal
while driving.
Keep the wheels in correct alignment.
Keep windows closed at high speeds.
Slow down when driving in crosswinds
and headwinds.
WA R N I N G
Never stop the engine when going down a
hill:
Stopping the engine when going down a
hill is dangerous. This causes the loss of
power steering and power brake control,
and may cause damage to the drivetrain.
Any loss of steering or braking control
could cause an accident.

Floor Mat
We recommend the use of Genuine
Mazda floor mats.
WARNING
Make sure the floor mats are hooked on the
retention pins to prevent them from
bunching up under the foot pedals:
Using a floor mat that is not secured is
dangerous as it will interfere with the
accelerator and brake pedal operation,
which could result in an accident.
Do not install two floor mats, one on top of
the other, on the driver's side:
Installing two floor mats, one on top of the
other, on the driver's side is dangerous as
the retention pins can only keep one floor
mat from sliding forward.
Loose floor mat(s) will interfere with the
foot pedals and could result in an accident.
If using an all-weather mat for winter use
always remove the original floor mat.
When setting a floor mat, position the
floor mat so that its grommets are inserted
over the pointed end of the retention posts.
Rocking the Vehicle
WA R N I N G
Do not spin the wheels at more than 56
km/h (35 mph), and do not allow anyone
to stand behind a wheel when pushing the
vehicle:
When the vehicle is stuck, spinning the
wheels at high speed is dangerous. The
spinning tire could overheat and explode.
This could cause serious injuries.
CAUTION
Too much rocking may cause engine
overheating, transaxle failure, and tire
damage.
If you must rock the vehicle to free it from
snow, sand or mud, depress the accelerator
slightly and slowly move the selector lever
from D to R position.

Winter Driving
Carry emergency gear, including tire
chains, window scraper, flares, a small
shovel, jumper cables, and a small bag of
sand or salt.
Ask an Authorized Mazda Dealer to check
the following:
Have the proper ratio of antifreeze in the
radiator.
Refer to Engine Coolant on page 6-22.
Inspect the battery and its cables. Cold
reduces battery capacity.
Use an engine oil appropriate for the
lowest ambient temperatures that the
vehicle will be driven in (page 6-20).
Inspect the ignition system for damage
and loose connections.
Use washer fluid made with
antifreeze―but do not use engine
coolant antifreeze for washer fluid (page
6-24).
NOTE
Remove snow before driving. Snow left
on the windshield is dangerous as it
could obstruct vision.
Do not apply excessive force to a
window scraper when removing ice or
frozen snow on the mirror glass and
windshield.
Never use warm or hot water for
removing snow or ice from windows and
mirrors as it could result in the glass
cracking.
Drive slowly. Braking performance can
be adversely affected if snow or ice
adheres to the brake components. If this
situation occurs, drive the vehicle
slowly, releasing the accelerator pedal
and lightly applying the brakes several
times until the brake performance
returns to normal.
▼ Snow Tires
Use snow tires on all 4 wheels
Do not go faster than 120 km/h (75 mph)
while driving with snow
tires. Inflate snow
tires 30 kPa (0.3 kgf/cm
2, 4.3 psi) more
than recommended on the tire pressure
label (driver's door frame), but never more
than the maximum cold-tire pressure
shown on the tires.

The vehicle is originally equipped with all
season radials designed to be used all year
around. In some extreme climates you
may find it necessary to replace them with
snow tires during the winter months to
further improve traction on snow and ice
covered roads.
WA R N I N G
Use only the same size and type tires (snow,
radial, or non-radial) on all 4 wheels:
Using tires different in size or type is
dangerous. Your vehi cle's handling could
be greatly affected and result in an
accident.
CAUTION
Check local regulations before using
studded tires.

Driving In Flooded Area
WA R N I N G
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 the vehicle on flooded roads
as it could cause short circuiting of
electrical/electronic parts, or engine
damage or stalling from water absorption.
If the vehicle has been immersed in water,
consult an Authorized Mazda Dealer.
Overloading
WA R N I N G
Be careful not to overload your vehicle:
The gross axle weight rating (GAWR) and
the gross vehicle weight rating (GVWR) of
the vehicle are on the Motor Vehicle Safety
Standard Label on the driver's door frame.
Exceeding these ratings can cause an
accident or vehicle damage. You can
estimate the weight of the load by
weighing the items (or people) before
putting them in the vehicle.

Turbocharger Information
CAUTION
After driving at freeway speeds or up a long hill, trailer towing for a long time, idle the
engine at least 30 seconds before stoppi ng it. Otherwise, the turbocharger could be
damaged.
 Racing or over-revving the engine, particularly after it's just been started, can damage the
turbocharger.
 To protect the engine from damage, the engine is designed so that it cannot be raced just
after starting it in extremely cold weather.
The turbocharger greatly enhances engine power. Its advanced design provides improved
operation and requires minimum maintenance.

To get the most from it, observe the following.
1. Change engine oil and filter accordi ng to Scheduled Maintenance (page 6-4).
2. Use only recommended engine oil (page 6-20). Extra additives are NOT recommended.

Trailer Towing (U.S.A. and Canada)
Your Mazda was designed and built primarily to carry passengers and cargo.
If you tow a trailer, follow these instructions because driver and passenger safety depends
on proper equipment and safe driving habits. Towing a trailer will affect handling, braking,
durability, performance, and fuel economy.
Never overload your vehicle or trailer. Cons ult an Authorized Mazda Dealer if you need
further details.
CAUTION
Do not tow a trailer during the first 1,000 km (600 miles) of your new Mazda. If you do, you
may damage the engine, transaxle, differential, wheel bearings, and other power-train
components.
NOTE
When towing, use of gasoline with a octane rating of 91 or higher is recommended.
Your vehicle is equipped with a Trailer Stability Control (TSC) mechanism, which
enhances vehicle stability when towing a trailer.
Refer to Trailer Stability Control (TSC) on page 4-106.
▼ We i g h t L i m i t s
TTW and GCWR
The total trailer weight (
TTW), gross combination weight rating (GCWR), gross axle
weight rating (GAWR), trailer load, and tr ailer tongue load must be within the
prescribed limits.
The total trailer weight (TTW ) is the sum of the weights of the trailer load (trailer
weight plus cargo), trailer hitch, 2 passen gers, and vehicle load (baggage, food, camp
gear, etc.). Never allow the to tal trailer weight (TTW) to exceed specifications in the
Trailer Towing-Load Table.
The maximum GCWR is the combination weig ht of the trailer and load plus the
towing vehicle (including tr ailer hitch, vehicle passengers, and load). It must not
exceed specifications in the load table.
GAWR and GVWR
Do not exceed front and rear GAWR (gross axle weight rating) and GVWR (gross vehicle
weight rating). If you do, vehicle handling, brak ing, and performance will be affected. These
values are also on the Motor Vehicle Safety Certification Label posted on the driver's door
frame.

High-altitude operation
CAUTION
Be aware of the towing load weight differences when towing at high altitudes. For altitudes
exceeding 1,000 meter (3,280 ft 10 in), always reduce the towing load by 10 % for every 1,000
meter (3,280 ft 10 in) increase in altitude from the load indicated under the maximum GCWR
heading in the trailer towing-load table. If the determined maximum total towing load
weight is exceeded, the engine and other power-train parts may be damaged.
