2020 MAZDA MODEL CX-30 Owners Manual

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 6-30).
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 8-22.
▼ 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.

Light Bulbs
▼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. We recommend an
Authorized Mazda Dealer when the
replacement is necessary.
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 the
fuse puller provided on the fuse

block located in the engine
compartment.
4. Inspect the fuse and replace it if it isblown.
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.
