light MAZDA MODEL 3 HATCHBACK 2019 Owners Manual (in English)

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 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
WA R N I N G
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.

Fuses
▼Fuses
Your vehicle's electrical system is
protected by fuses.

If any lights, accessori
es, 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. 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 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.

Insects, tar, tree sap, bird droppings,
industrial fallout, and similar deposits can
damage the finish if not removed
immediately. When prompt washing with
plain water is ineffective, use a mild soap
made for use on vehicles.

Thoroughly rinse off all soap with
lukewarm or cold water. Do not allow
soap to dry on the finish.

After washing the vehicle, dry it with a
clean chamois to prevent water spots from
forming.
WA R N I N G
Dry off brakes that have become wet by
driving slowly, releasing the accelerator
pedal and lightly applying the brakes
several times until the brake performance
returns to normal:
Driving with wet brakes is dangerous.
Increased stopping distance or the vehicle
pulling to one side when braking could
result in a serious accident. Light braking
will indicate whether the brakes have been
affected.
When using an automatic car wash
Retract the door mirrors.
The automatic car wash brushes could
reduce the paint lustre or hasten paint
deterioration.
When using a high water pressure car
wash
High water temperature and high water
pressure car washers are available
depending on the type of car wash
machine. If the car washer nozzle is put
too close to the vehicle, the force of the
spray could damage or deform the
molding, affect the se alability of parts, and
allow water to penetrate the interior. Keep
a sufficient space (30 cm (12 in) or more)
between the nozzle and the vehicle. In
addition, do not spend too much time
spraying the same area of the vehicle, and
be very careful when spraying between
gaps in doors and around windows.
Wa x i n g
Your vehicle needs to be waxed when
water no longer beads on the finish.
Always wash and dry the vehicle before
waxing it. In addition to the vehicle body,
wax the metal trim to m aintain its luster.

1. Use wax which contains no abrasives. Waxes containing abrasive will remove
paint and could damage bright metal
parts.
2. Use a good grade of natural wax for metallic, mica, and solid colors.
3. When waxing, coat evenly with the sponge supplied or a soft cloth.
4. Wipe off the wax with a soft cloth.
NOTE
A spot remover to remove oil, tar, and
similar materials will usually also take off
the wax. Rewax these areas even if the rest
of the vehicle does not need it.

▼Repairing Damage to the Finish
Deep scratches or chips on the finish
should be repaired
promptly. Exposed
metal quickly rusts and can lead to major
repairs.
CAUTION
If your Mazda is damaged and needs metal
parts repaired or replaced, make sure the
body shop applies anti-corrosion materials
to all parts, both repaired and new. This
will prevent them from rusting.
▼ Bright-Metal Maintenance
Use tar remover to r
emove road tar and
insects. Never do this with a knife or
similar tool.
To prevent corrosion on bright-metal
surfaces, apply wax or chrome
preservative and rub it to a high luster.
During cold weather or in coastal areas,
cover bright-metal parts with a coating
of wax or preservative heavier than
usual. It would also help to coat them
with noncorrosive p etroleum jelly or
some other protective compound.
CAUTION
Do not use steel wool, abrasive cleaners, or
strong detergents containing highly
alkaline or caustic agents on
chrome-plated or anodized aluminum
parts. This may result in damage to the
protective coating and cause discoloration
or paint deterioration.
▼ Underbody Maintenance
Road chemicals and s
alt used for ice and
snow removal and solvents used for dust
control may collect on the underbody. If
not removed, they will speed up rusting
and deterioration of such underbody parts
as fuel lines, frame, floor pan, and exhaust
system, even though these parts may be
coated with anti-corrosive material.

Thoroughly flush the underbody and
wheel housings with lukewarm or cold
water at the end of each winter. Try also to
do this every month.

Pay special attention to these areas
because they easily hide mud and dirt. It
will do more harm than good to wet
down the road grime without removing
it.

The lower edges of doors, rocker panels,
and frame members have drain holes that
should not be clogged. Water trapped there
will cause rusting.
WA R N I N G
Dry off brakes that have become wet by
driving slowly, releasing the accelerator
pedal and lightly applying the brakes
several times until the brake performance
returns to normal:
Driving with wet brakes is dangerous.
Increased stopping distance or the vehicle
pulling to one side when braking could
result in a serious accident. Light braking
