2021 MAZDA MODEL CX-3 spare wheel

2. Put a vehicle with an automatictransaxle in Park (P), a manual
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.

Antitheft lug nut
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.

▼Mounting the Spare Tire
1. Remove dirt and grime from the
mounting surfaces of the wheel and
hub, including the hub bolts, with a
cloth.

WA R N I N G
Make sure the mounting surfaces of the
wheel, hub and lug nuts are clean
before changing or replacing tires:
When changing or replacing a tire, not
removing dirt and grime from the
mounting surfaces of the wheel, hub
and hub bolts is dangerous. The lug
nuts could loosen while driving and
cause the tire to come off, resulting in
an accident.
2. Mount the spare tire.
3. Install the lug nuts with the beveled edge inward; tighten them by hand.

WARNING
Do not apply oil or grease to lug nuts
and bolts and do not tighten the lug
nuts beyond the recommended
tightening torque:
Applying oil or grease to lug nuts and
bolts is dangerous. The lug nuts could
loosen while driving and cause the tire
to come off, resulting in an accident. In
addition, lug nuts and bolts could be
damaged if tightened more than
necessary.
4. Turn the lug wrench counterclockwise and lower the vehicle.

12. Thread the buckle through the wheel asshown in the figure.

13. Thread the belt through the bucklewhile pressing the tire to the seatback.

14. Pull the belt end to secure the flat tire.
15. Insert the luggag e compartment cover
from the top of the luggage
compartment opening with the cloth
side of the cover facing outward, and
slide it between the flat tire and the
inside perimeter of the luggage
compartment opening.

16. Check the tire inflation pressure. Refer to the specification charts on
page 9-7.
17. Have the flat tire repaired or replaced as soon as possible.
WA R N I N G
Do not drive with any tires that have
incorrect air pressure:
Driving on tires with incorrect air pressure
is dangerous. Tires with incorrect pressure
could affect handling and result in an
accident. When you check the regular tires'
air pressure, check the spare tire, too.
NOTE
To prevent the jack and tool from rattling,
store them properly.

Tire Maintenance
Improper or inadequate vehicle maintenance can cause tires to wear abnormally. Here are
some important maintenance points:
▼Tire Inflation Pressure
Inspect all tire pressure monthly (including the spare) when the tires are cold. Maintain
recommended pressures for the best ride, top handling, and minimum tire wear. Use the
pressures specified on the vehicle tire informat
ion placard or tire label for optimum service.
▼Tire Rotation
To equalize tread wear, rotate the tires every 12,000 km (7,500 miles) at the latest or sooner
if irregular wear develops. Mazda recommends to rotate every 8,000 km (5,000 miles) to
help increase tire life and di
stribute wear more evenly.
Do not include (TEMPORARY USE ONLY)
spare tire in rotation.Forward
Inspect the tires 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
Severe braking
After rotation, inflate all tire pressures to sp ecification (page 9-7) and inspect the lug nuts
for tightness.
CAUTION
Rotate unidirectional tires and radial tires that have an asymmetrical tread pattern or studs
only from front to rear, not from side to side . Tire performance will be weakened if rotated
from side to side.
