2023 MAZDA CX3 Owners Manual

▼Tire Rotation
WARNING
Rotate tires periodically:
Irregular tire wear is dangerous. To
equalize tread wear for maintaining
good performance
in handling and
braking, rotate the tires periodically or
sooner if irregular wear develops.
Please refer to Scheduled maintenance
for your tire rotation interval.
During rotation, inspect them for
correct balance.

1. Forward
Do not include (TEMPORARY USE
ONLY) spare tire in rotation.

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Severe braking

After rotation, inflate all tire pressures
to specification on page 9-8 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 reduced if rotated from side to
side.
▼ Replacing a Tire
WARNING
Always use tires that are in good
condition:
Driving with worn tires is dangerous.
Reduced braking , steering , and
traction could result in an accident.
Replace all four tires at the same
time:
Replacing just one tire is dangerous. It
could cause poor handling and poor
braking resulting in loss of vehicle
control. Mazda strongly recommends
that you replace all four tires at the
same time.
If a tire wears evenly, a wear indicator
will appear as a solid band across the
tread.
Replace the tire when this happens.

3. Tread wear indicator

You should replace the tire before the
band crosses the entire tread.
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 8-23.
▼Temporary Spare Tire
Inspect the temporary spare tire at
least monthly to make sure it is
properly
inflated and stored.
NOTE
The temporary spare tire condition
gradually deteriorates even if it has not
been used.
The temporary spare tire is easier to
handle because of its construction
which is lighter and smaller than a
conventional 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 9-8.

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 6-32).
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 load ing 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 8-23.
▼ Replacing a Wheel
WARNING
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.

▼Replacing Light Bulbs
All the light bulbs are the LED type.
The LED bulb cannot be replaced as a
single unit because it is an integrated
unit.
The LED bulb has to be replaced with
the unit. If a replacement is necessary,
consult an Authorized Mazda Dealer.
Fuses
▼Fuses
Your vehicle's electrical system is
protected by fuses.

If any lights, accessories, or controls do
not work, inspect the appropriate
circuit protector. If a fuse has blown,
the inside element will be melted.

If the same fuse
blows again, avoid
using that system and consult an
Authorized Mazda Dealer as soon as
possible.
▼ Fuse Replacement
Replacing the fuses on the vehicle's
left side
If the electrical system does not work,
first inspect the fuses on the vehicle's
left side.

1. Make sure the ignition is switched
off, and other switches are off.
2. Open the fuse panel cover.

3. Pull the fuse straight out with thefuse puller provided on the fuse
block located in the engine
compartment.
4. Inspect the fuse and replace it if it is
blown.
1. Normal
2. Blown

5. Insert a new fuse of the same
amperage rating, and make sure it
fits tightly. If it does not
fit tightly,
have an expert install it. Consult an
Authorized Mazda Dealer.
If you have no spare fuses, borrow
one of the same rating from a
circuit not essential to vehicle
operation, such as the audio or
accessory socket circuit.
CAUTION
Always replace a fuse with a
genuine Mazda fuse or equivalent
of the same rating. Otherwise, you
may damage the electric system.
6. Reinstall the cover and make sure that it is securely installed.
Replacing the fuses under the hood
If the headlights or other electrical
components do not work and the fuses
in the cabin are normal, inspect the
fuse block under the hood.
If a fuse is blown, it must be replaced.
Follow these steps:

1. Make sure the ignition is switched
off, and other switches are
off.
2. Remove the fuse block cover.
3. If any fuse but the MAIN fuse is blown, replace it with a new one of
the same amperage rating .
1. Normal
2. Blown

WARNING
Do not replace the main fuse by
yourself. Have an Authorized
Mazda Dealer perform the
replacement:
Replacing the fuse by yourself is
dangerous because the MAIN fuse
is a high current fuse. Incorrect
replacement could cause an
electrical shock or a short circuit
resulting in a fire.
4. Reinstall the cover and make sure that it is securely installed.
