Key Battery Replacement
▼Key Battery Replacement
If the buttons on the transmitter are
inoperable and the operation indicator
light does not
flash, the battery may be
dead.
Replace with a new battery before the
transmitter becomes unusable.
CAUTION
 Make sure the battery is installed
correctly. Battery leakage could occur
if it is not installed correctly.
 When replacing the battery, be
careful not to touch any of the
internal circuitry and electrical
terminals, bend the electrical
terminals, or get dirt in the
transmitter as the transmitter could
be damaged.
 There is the danger of explosion if
the battery is not correctly replaced.
 Dispose of used batteries according
to the following instructions.
 Insulate the plus and minus
terminals of the battery using
cellophane or equivalent tape.
 Never disassemble.
 Never throw the battery into fire or
water.
 Never deform or crush.
 Replace only with the same type
battery (CR2032 or equivalent).
The following conditions indicate that
the battery power is low:
A message, “Low Key Fob Battery.
Replace Battery” is displayed on the
multi-information display when the
power switch is switched OFF.
The system does not operate and the
operation indicator light on the
transmitter does not flash when the
buttons are pressed.
The system's operational range is
reduced.
Incorrect battery replacement
operation may damage the key.
Replacing the battery at an Authorized
Mazda Dealer is recommended. If
replacing the battery by yourself,
follow the instruction.
Replacing the key battery

Tires
▼Tires
For reasons of proper performance,
safety, and better energy
effi ciency,
always maintain recommended tire
in flation pressures and stay within the
recommended load limits and weight
distribution.
WARNING
Using Di fferent Tire Types:
Driving your vehicle with di fferent
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
speci fied for the vehicle (page 9-5)
is dangerous. It could seriously a ffect
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 speci fied for the
vehicle.
▼ Tire In
flation Pressure
WARNING
Always in flate the tires to the correct
pressure:
Overin flation or underinfl ation of tires
is dangerous. Adverse handling or
unexpected tire failure could result in a
serious accident.
Refer to Tires on page 9-5.
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 when
the tires are cold. Maintain
recommended pressures for the best
ride, handling , and minimum tire
wear.
Refer to the speci fication charts (page
9-5).
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.
Underin flation can cause reduced
energy e fficiency, uneven and
accelerated tire wear, and poor
sealing of the tire bead, which will
deform the wheel and cause
separation of tire from rim.
Overin flation 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 in flating, have it inspected.

▼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.
NOTE
Because your vehicle is not equipped
with a spare tire, you cannot do a tire
rotation safely with the jack that comes
with your vehicle. Have an Authorized
Mazda Dealer perform tire rotation.

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, in flate all tire pressures
to specifi cation on page 9-5 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.
Maintenance and Care
Owner Maintenance

MX
-30_8JD4-EA -21G_Edition2_new 2021-5-18 14:38:07

Replace the tire when this happens.
1. New tread
2. Worn tread
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. 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 8-21.
▼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
aff ected, leading to loss of control
and an accident.
CAUTION
A wrong-sized wheel may adversely
a ff ect:
 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.

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,
fi
rst inspect the fuses on the vehicle's
left side.

1. Make sure the power switch is
switched o ff, 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 motor
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 rat ing , 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.
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 power switch isswitched off , and other switches
are o ff.
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.
