Mazda CX-3 (2019 year). Manual

After rotation, inflate all tire pressures to
specification (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 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.

New tread

Tread wear indicator

Worn tread

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 8-25.

▼ 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 9-7.

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).

▼ 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.

WARNING

Never touch the glass portion of a halogen
bulb with your bare hands and always
wear eye protection when handling or
working around the bulbs:
When a halogen bulb breaks, it is
dangerous. These bulbs contain
pressurized gas. If one is broken, it will
explode and serious injuries could be
caused by the flying glass.
If the glass portion is touched with bare
hands, body oil could cause the bulb to
overheat and explode when lit.

Always keep halogen bulbs out of the reach
of children:
Playing with a halogen bulb is dangerous.
Serious injuries could be caused by
dropping a halogen bulb or breaking it
some other way.

CAUTION

When removing the lens or lamp unit using
a flathead screwdriver, make sure that the
flathead screwdriver does not contact the
interior terminal. If the flathead screwdriver
contacts the terminal, a short circuit may
occur.

NOTE

•

To replace the bulb, contact an
Authorized Mazda Dealer.

•

If the halogen bulb is accidentally
touched, it should be cleaned with
rubbing alcohol before being used.

•

Use the protective cover and carton for
the replacement bulb to dispose of the
old bulb promptly and out of the reach
of children.

▼ Replacing Exterior Light Bulbs

Headlights (With LED headlights)

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. We recommend an Authorized
Mazda Dealer when the replacement is
necessary.

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 the fuse

puller provided on the fuse block
located in the engine compartment.

4. Inspect the fuse and replace it if it is

blown.

Normal

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. We recommend 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 OUTLET 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.

Normal

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.
