Battery
▼ Battery
WA R N I N G
Wash hands after handling the battery and
related accessories:
Battery posts, terminals and related
accessories contain lead and lead
compounds, chemicals known to the State
of California to cause cancer and
reproductive harm.
Read the following precautions
carefully before using the battery or
inspecting to ensure safe and correct
handling:
Always wear eye protection when
working near the battery:
Working without eye protection is
dangerous. Battery fluid contains
SULFURIC ACID which could cause
blindness if splashed into your eyes. Also,
hydrogen gas produced during normal
battery operation, could ignite and cause
the battery to explode.

Wear eye protection and protective
gloves to prevent contact with battery
fluid:
Spilled battery fluid is dangerous.
Battery fluid contains SULFURIC ACID
which could cause serious injuries if it gets
in eyes, or on the skin or clothing. If this
happens, immediately flush your eyes with
water for 15 minutes or wash your skin
thoroughly and get medical attention.
Always keep batteries out of the
reach of children:
Allowing children to play near batteries is
dangerous. Battery fluid could cause
serious injuries if it gets in the eyes or on the
skin.
Keep flames and sparks away from
open battery cells and do not allow metal
tools to contact the positive (+) or negative
(-) terminal of the battery when working
near a battery. Do not allow the positive (+)
terminal to contact the vehicle body:
Flames and sparks near open battery cells
are dangerous. Hydrogen gas, produced
during normal battery operation, could
ignite and cause the battery to explode. An
exploding battery can cause serious burns
and injuries. Keep all flames including
cigarettes and sparks away from open
battery cells.
Keep all flames and sparks away
from open battery cells because hydrogen
gas is produced from open battery cells
while charging the battery or adding
battery fluid:
Flames and sparks near open battery cells
are dangerous. Hydr ogen gas, produced
during normal battery operation, could
ignite and cause the battery to explode. An
exploding battery can cause serious burns
and injuries. Keep all flames including
cigarettes and sparks away from open
battery cells.
NOTE
Before performing battery maintenance,
remove the battery cover.

▼Battery Maintenance
To get the best service from a battery:
Keep it securely mounted.
Keep the top clean and dry.
Keep terminals and connections clean,
tight, and coated with
petroleum jelly or
terminal grease.
Rinse off spilled electrolyte immediately
with a solution of water and baking
soda.
If the vehicle will not be used for an
extended time, disconnect the battery
cables and charge the battery every 6
weeks.
▼ Battery Replacement
Contact an Authorized Mazda Dealer for a
battery replacement purchase.
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 b
attery 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:
The KEY warning indication/warning
light (red) in the instrument cluster turns
on and a message, "Low Key Fob
Battery. Replace Battery", is displayed
on the multi-information display when
the ignition 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.
Replacing the battery at an Authorized
Mazda Dealer is recommended to prevent
damage to the key. If replacing the battery
by yourself, follow the instruction.
Replacing the key battery
1. Remove the lower cover while pressing the knob in the direction of
the arrow.
2. Press in the tab to unlock the upper
cover.

Tires
▼Tires
For reasons of proper performance, safety,
and better fuel economy, always maintain
recommended tire inflation pressures and
stay within the recommended load limits
and weight distribution.
WA R N I N G
Using Different Tire Types:
Driving your vehicle with
different 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
specified for the vehicle (page 9-9) is
dangerous. It could seriously affect 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 specified for
the vehicle.
▼ Tire Inflation Pressure
WA R N I N G
Always
inflate the tires to the correct
pressure:
Overinflation or
underinflation of tires is
dangerous. Adverse handling or
unexpected tire failure could result in a
serious accident.
Refer to Tires on page 9-9.
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
(including the spare) when the tires are
cold. Maintain recom mended pressures for
the best ride, handling, and minimum tire
wear.
Refer to the specification charts (page
9-9).
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.

Mazda3_8HE9-EA-18K_Edition3 2018-11-21 14:31:58

Underinflation can cause reduced fuel
economy, uneven and accelerated tire
wear, and poor sealing of the tire bead,
which will deform the wheel and cause
separation of tire from rim.
Overinflation 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 inflating,
have it inspected.
▼Tire Rotation
WA R N I N G
Rotate tires periodically:
Irregular tire wear is dangerous. To
equalize tread wear for maintaining good
performance in handling and braking,
rotate the tires every 16,000 km (10,000
miles). However Mazda recommends to
rotate every 8,000 km (5,000 miles) to help
increase tire life and distribute wear more
evenly.
Refer to Scheduled Maintenance (U.S.A.
and Puerto Rico) on page 6-4.
Refer to Scheduled Maintenance (Canada)
on page 6-6.
Refer to Scheduled Maintenance (Mexico)
on page 6-8.

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 (page 9-9) 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.
