spare wheel MAZDA MODEL CX-3 2021 Owners Manual

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.

Mexico
The vehicle is originally equipped with
summer tires desi gned for optimum
traction on wet and dry roads. If your
vehicle is to be used on snow and ice
covered roads, Mazda recommends that
you replace the tires originally equipped
on your vehicle with snow tires during the
winter months.
Except Mexico
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 vehicle's handling could
be greatly affected and result in an
accident.
CAUTION
Check local regulations before using
studded tires.
NOTE
If your vehicle is equipped with the tire
pressure monitoring system, the system
may not function correctly when using
tires with steel wire reinforcement in the
sidewalls (page 4-141).
▼ Tire Chains
Check local regulations before using tire
chains.
CAUTION

Chains may affect handling.
 Do not go faster than 50 km/h (30 mph)
or the chain manufacturer's
recommended limit, whichever is lower.
 Drive carefully and avoid bumps, holes,
and sharp turns.
 Avoid locked-wheel braking.
 Do not use chains on a temporary spare
tire; it may result in damage to the
vehicle and to the tire.
 Do not use chains on roads that are free
of snow or ice. The tires and chains could
be damaged.

Dynamic Stability Control(DSC)
The Dynamic Stability Control (DSC)
automatically controls braking and engine
torque in conjunction with systems such as
ABS and TCS to help control side slip
when driving on slippery surfaces, or
during sudden or evasive maneuvering,
enhancing vehicle safety.

Refer to ABS (page 4-65) and TCS (page
4-66).

DSC operation is possible at speeds
greater than 20 km/h (12 mph).

The warning light turns on when the
system has a malfunction.
Refer to Contact Authorized Mazda
Dealer and Have Vehicle Inspected on
page 7-29.
WA R N I N G
Do not rely on the Dynamic Stability
Control as a substitute for safe driving:
The Dynamic Stability Control (DSC)
cannot compensate for unsafe and reckless
driving, excessive speed, tailgating
(following another vehicle too closely), and
hydroplaning (reduced tire friction and
road contact because of water on the road
surface). You can still have an accident.
CAUTION
 The DSC may not operate correctly
unless the following are observed:
 Use tires of the correct size
specified for
your Mazda on all 4 wheels.
 Use tires of the same manufacturer,
brand and tread pattern on all 4
wheels.
 Do not mix worn tires.
 The DSC may not operate correctly when
tire chains are used or a temporary spare
tire is installed because the tire diameter
changes.
▼ TCS/DSC Indicator Light
This indicator light stays on for a few
seconds when the ignition is switched ON.
If the TCS or DSC is operating, the
indicator light flashes.

If the light stays on, the TCS, DSC or the
brake assist system may have a
malfunction and they may not operate
correctly. Take your vehicle to an
Authorized Mazda Dealer.

Do not use the front bumper to push other vehi cles or obstructions such as when pulling
out of a parking space. Otherwise, the radar sensor (front) could be hit and its position
deviated.
 Do not remove, disassemble, or modify the radar sensor (front).
 For repairs, replacement or paint work around the radar sensor (front), consult an
Authorized Mazda Dealer.
 Do not modify the suspension. If the suspensi on are modified, the vehicle's posture could
change and the radar sensor (front) may not be able to correctly detect a vehicle ahead or
an obstruction.
NOTE
Under the following conditions, the radar sensor (front) may not be able to detect vehicles
ahead or obstructions correctly and each system may not operate normally.
The rear surface of a vehicle ahead does not reflect radio waves effectively, such as an
unloaded trailer or an automobile with a loading platform covered by a soft top,
vehicles with a hard plastic tailgate, and round-shaped vehicles.
Vehicles ahead with low vehicle height and thus less area for reflecting radio waves.
Visibility is reduced due to a vehicle ahead ca sting off water, snow, or sand from its tires
and onto your windshield.
The luggage compartment is loaded with heavy objects or the rear passenger seats are
occupied.
Ice, snow, or soiling is on the front surface of the front emblem.
During inclement weather such as rain, snow, or sand storms.
When driving near facilities or objects emitting strong radio waves.
Under the following conditions, the radar sensor (front) may not be able to detect vehicles
ahead or obstructions.
The beginning and end of a curve.
Roads with continuous curves.
Narrow lane roads due to road construction or lane closures.
The vehicle ahead enters the radar sensor's blind spot.
The vehicle ahead is running abnormally due to accident or vehicle damage.
Roads with repeated up and down slopes
Driving on poor roads or unpaved roads.
The distance between your vehicle and the vehicle ahead is extremely short.
A vehicle suddenly comes close such as by cutting into the lane.
To prevent incorrect operation of the system, use tires of the same specified size,
manufacturer, brand, and tread pattern on all four wheels. In addition, do not use tires
with significantly different wear patterns or tire pressures on the same vehicle (Including
the temporary spare tire).
If the battery power is weak, the system may not operate correctly.

Tire Pressure Monitoring System*
The Tire Pressure Monitoring System (TPMS) monitors the pressure for each tire.
If tire pressure is too low in one or more tires, the system will inform the driver via the
warning light in the instrument cluster and by the warning beep sound.
Refer to Contact Authorized Mazda Dealer and Have Vehicle Inspected on page 7-29.
Refer to Taking Action on page 7-33.
Refer to Tire Inflation Pressure Warning Beep on page 7-44.

The tire pressure sensors installed on each wheel send tire pressure data by radio signal to
the receiver unit in the vehicle.
Tire pressure sensors
NOTE
When the ambient temperature is low due to seasonal changes, tire temperatures are also
lower. When the tire temperature decreases, the air pressure decreases as well. The TPMS
warning light may illumina te more frequently. Visually inspect the tires daily before driving,
and check tire pressures monthly with a tire pressure gauge. When checking tire pressures,
use of a digital tire pressure gauge is recommended.

TPMS does not alleviate your need to check the pressure and condition of all four tires
regularly.
CAUTION
 Each tire, including the spare (if provided), should be checked monthly when cold and
inflated to the inflation pressure recommended by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your vehicle has tires of a different size than the
size indicated on the vehicle placard or tire in flation pressure label, you should determine
the proper tire inflation pressure for those tires.)

Tires
For reasons of proper performance, safety,
and better fuel economy, always maintain
recommended tire inflation pressures and
stay within the recommended load limits
and weight distribution.
WA R N I N G
Using Different Tire Types:
Driving your vehicle with different types of
tires is dangerous. It could cause poor
handling and poor braking; leading to loss
of control.
Except for the limited use of the temporary
spare tire, use only the same type tires
(radial, bias-belted, bias-type) on all four
wheels.
Using Wrong-Sized Tires:
Using any other tire size than what is
specified for the vehicle (page 9-7) is
dangerous. It could seriously affect ride,
handling, ground clearance, tire clearance,
and speedometer calibration. This could
cause you to have an accident. Use only
tires that are the correct size specified for
the vehicle.
▼ Tire Inflation Pressure
WA R N I N G
Always inflate the tires to the correct
pressure:
Overinflation or underinflation of tires is
dangerous. Adverse handling or
unexpected tire failure could result in a
serious accident.
Refer to Tires on page 9-7.

CX-3_8JL1-EA-20G_Edition1_old
2020-5-22 15:31:00

Use only a Mazda-genuine tire valve cap:
Use of a non-genuine part is dangerous as
the correct tire air pressure cannot be
maintained if the tire valve becomes
damaged. If the vehicle is driven under this
condition, the tire air pressure will decrease
which could result in a serious accident. Do
not use any part for the tire valve cap that
is not a Mazda-genuine part.
Inspect all tire pressures monthly
(including the spare) when the tires are
cold. Maintain recommended pressures for
the best ride, handlin g, and minimum tire
wear.
Refer to the specification charts (page
9-7).
NOTE
Always check tire pressure when tires
are cold.
Warm tires normally exceed
recommended pressures. Do not release
air from warm tires to adjust the
pressure.
Underinflation can cause reduced fuel
economy, uneven and accelerated tire
wear, and poor sealing of the tire bead,
which will deform the wheel and cause
separation of tire from rim.
Overinflation can produce a harsh ride,
uneven and accelerated tire wear, and a
greater possibility of damage from road
hazards.
Keep your tire pressure at the correct
levels. If one frequently needs inflating,
have it inspected.
▼ Tire Rotation
WA R N I N G
Rotate tires periodically:
Irregular tire wear is dangerous. To
equalize tread wear for maintaining good
performance in handling and braking,
rotate the tires every 12,000 km (7,500
miles). However Mazda recommends to
rotate every 8,000 km (5,000 miles) to help
increase tire life and distribute wear more
evenly.
Refer to Scheduled Maintenance on page
6-4.

During rotation, inspect them for correct
balance.

Do not include (TEMPORARY USE ONLY)
spare tire in rotation.Forward
Also, inspect them for uneven wear and
damage. Abnormal wear is usually caused
by one or a combination of the following:

Incorrect tire pressure
Improper wheel alignment
Out-of-balance wheel

tire. This tire should be used only for an
emergency and only for a short distance.

Use the temporary spare tire only until the
conventional tire is repaired, which should
be as soon as possible.
Refer to Tires on page 9-7.

CAUTION
Do not use your temporary spare tire rim
with a snow tire or a conventional tire.
Neither will properly fit and could
damage both tire and rim.
 The temporary spare tire has a tread life
of less than 5,000 km (3,000 miles). The
tread life may be shorter depending on
driving conditions.
 The temporary spare tire is for limited
use, however, if the tread wear
solid-band indicator appears, replace the
tire with the same type of temporary
spare (page 6-38).
NOTE
Tires degrade over time, even when they
are not being used on the road. It is
recommended that tires generally be
replaced when they are 6 years or older.
Heat caused by hot climates or frequent
high loading conditions can accelerate the
aging process. You should replace the
spare tire when you replace the other road
tires due to the aging of the spare tire. The
period in which the tire was manufactured
(both week and year) is indicated by a
4-digit number.
Refer to Tire Labeling on page 8-25.
▼ Replacing a Wheel
WA R N I N G
Always use wheels of the correct size on
your vehicle:
Using a wrong-sized wheel is dangerous.
Braking and handling could be
affected,
leading to loss of control and an accident.
CAUTION
A wrong-sized wheel may adversely affect:
 Tire fit
 Wheel and bearing life
 Ground clearance
 Snow-chain clearance
 Speedometer calibration
 Headlight aim
 Bumper height
 Tire Pressure Monitoring System
*
NOTE
When replacing a wheel, make sure the
new one is the same as the original
factory wheel in diameter, rim width,
and offset (inset/outset).
For details, contact an Authorized
Mazda Dealer.

Proper tire balancing provides the best
riding comfort and helps reduce tread
wear. Out-of-balance tires can cause
vibration and uneven wear, such as
cupping and flat spots.

3. Turn the wing bolt completely to secure the jack.
NOTE
If the jack is not completely secured, it
could rattle while driving. Make sure
the jack screw is sufficiently tightened.
4. Insert the cover tabs and install the cover.
NOTE
Verify that the cover is securely
installed.
Maintenance
Always keep the jack clean.
Make sure the moving parts are kept
free from dirt or rust.
Make sure the screw thread is
adequately lubricated.
▼ Spare Tire
Your Mazda has a temporary spare tire.
The temporary spare tire is lighter and
smaller than a conventional tire, and is
designed only for emergency use and
should be used only for VERY short
periods. Temporary spare tires should
NEVER be used fo
r long drives or
extended periods.
WA R N I N G
Do not install the temporary spare tire on
the front wheels (driving wheels):
Driving with the temporary spare tire on
one of the front driving wheels is
dangerous. Handling will be affected. You
could lose control of the vehicle, especially
on ice or snow bound roads, and have an
accident. Move a regular tire to the front
wheel and install the temporary spare tire
to the rear.
CAUTION
 When using the temporary spare tire,
driving stability may decrease compared
to when using only the conventional tire.
Drive carefully.
 To avoid damage to the temporary spare
tire or to the vehicle, observe the
following precautions:
 Do not exceed 80 km/h (50 mph).
 Avoid driving over obstacles. Also, do
not drive through an automatic car
wash. This tire's diameter is smaller
than a conventional tire, so the ground
clearance is reduced.
 Do not use a tire chain on this tire
because it will not fit properly.
 Do not use your temporary spare tire
on any other vehicle, it has been
designed only for your Mazda.
 Use only one temporary spare tire on
your vehicle at the same time.

transaxle in Reverse (R) or 1, and turn
off the engine.
3. Turn on the hazard warning flasher.
4. Have passengers get out of the vehicle
and away from the vehicle and traffic.
5. Remove any luggage, the jack, tools, and spare tire (page 7-3).
6. Block the wheel diagonally opposite the flat tire. When blocking a wheel,
place a tire block both in front and
behind the tire.
NOTE
When blocking a tire, use rocks or
wood blocks of sufficient size if
possible to hold the tire in place.
▼Removing a Flat Tire
WARNING
When jacking-up a vehicle, always shift the
shift lever to 1st or R position (manual
transaxle vehicle) or shift the selector lever
to P position (automatic transaxle vehicle),
apply the parking brake, and place wheel
blocks in the position diagonally opposed
to the jack:
Changing a flat tire without using wheel
blocks is dangerous because the vehicle
may move and fall off the jack even with
the shift lever in 1st or R position, or the
selector lever is in P position, which could
result in an accident.
1. If your vehicle is equipped with a
wheel cover, pry off the wheel cover
with the beveled end of the jack lever.

NOTE
Force the end of the jack lever firmly
between wheel and cover, or removal
will be difficult.
CAUTION
Align the notch on the wheel cover with
the valve stem when installing it.

WA R N I N G
Do not jack up the vehicle higher than
is necessary:
Jacking up the vehicle higher than is
necessary is dangerous as it could
destabilize the vehicle resulting in an
accident.
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.
9. Remove the lug nuts by turning them counterclockwise; then remove the
wheel and center cap.
▼Locking Lug Nuts*
If your vehicle has Mazda optional
antitheft wheel lug nuts, each wheel will
have one locking lug nut that locks the
wheel and tire, and you must use a special
key to unlock the lock
ing lug nut. This key
is stored in the glove compartment.
Register the key and lug nuts with the lock
manufacturer by filling out the card
provided in the glove compartment and
mailing it in the accompanying envelope.
If you lose this key, consult an Authorized
Mazda Dealer or use the lock
manufacturer's order form, which is with
the registration card.
Accessory wheel locks cannot be used on
steel wheels. This includes situations when
the spare tire is installed. If the spare tire is
installed, one of th e original lug nuts
(which should still be in the vehicle) must
be installed in place of the wheel lock.
