Battery

WARNING

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

À uid contains SULPHURIC

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

À uid:

Spilled battery

À uid is dangerous.

Battery

À uid contains SULPHURIC ACID which could cause serious injuries if it gets

in eyes, or on the skin or clothing. If this happens, immediately

À ush 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

À uid could cause serious

injuries if it gets in the eyes or on the skin.

Keep

À ames 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

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
leads and charge the battery every six
weeks.

Inspecting Electrolyte Level

A low level of electrolyte

À uid will cause

the battery to discharge quickly.

Upper level

Lower level

Inspect the electrolyte level at least once
a week. If it is low, remove the caps and
add enough distilled water to bring the
level between the upper and lower level
(illustration).

Do not over

¿ ll.

Examine the speci

¿ c gravity of the

electrolyte with a hydrometer, especially
during cold weather. If it is low, recharge
the battery.

Battery Recharging

NOTE

Before performing maintenance or

recharging the battery, turn off all
accessories and stop the engine.

To disconnect the battery, remove the

negative lead

¿ rst. Install it last when

connecting the battery.

Be sure to remove the caps before

recharging the battery.

(With i-stop system)

Do not quick-charge the battery.

If the battery quickly discharges

because, for example, the lights were
left on too long with the engine off,
slow-charge it as required by battery
size and charger capacity.

If the battery gradually discharges

because of high electric load while the
vehicle is being used, recharge it as
required by battery size and charger
capacity.

Battery Replacement

Contact an Authorised Mazda Repairer for
a battery replacement purchase.

If the buttons on the transmitter are
inoperable and the operation indicator
light does not

À ash, 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

¿ re or

water.

Never deform or crush.

Replace only with the same type

battery (CR2025 or equivalent).

Tyres

For reasons of proper performance, safety,
and better fuel economy, always maintain
recommended tyre in

À ation pressures and

stay within the recommended load limits
and weight distribution.

WARNING

Using Different Tyre Types:
Driving your vehicle with different
types of tyres is dangerous. It could
cause poor handling and poor braking;
leading to loss of control.
Except for the limited use of the
temporary spare tyre, use only the same
type tyres (radial, bias-belted, bias-type)
on all four wheels.

Using Wrong-Sized Tyres:
Using any other tyre size than what is
speci

¿ ed for the vehicle (page 9-8 )

is dangerous. It could seriously affect
ride, handling, ground clearance,
tyre clearance, and speedometer
calibration. This could cause you to
have an accident. Use only tyres that
are the correct size speci

¿ ed for the

vehicle.

Owner Maintenance

Tyre In

À ation Pressure

WARNING

Always in

À ate the tyres to the correct

pressure:
Overin

À ation or underinÀ ation of tyres

is dangerous. Adverse handling or
unexpected tyre failure could result in
a serious accident.
Refer to Tyres on page 9-8 .

Use only a Mazda-genuine tyre valve
cap:
Use of a non-genuine part is dangerous
as the correct tyre air pressure cannot
be maintained if the tyre valve becomes
damaged. If the vehicle is driven under
this condition, the tyre air pressure
will decrease which could result in a
serious accident. Do not use any part
for the tyre valve cap that is not a
Mazda-genuine part.

Inspect all tyre pressures monthly when
the tyres are cold. Maintain recommended
pressures for the best ride, handling, and
minimum tyre wear.
Refer to the speci

¿ cation charts (page

9-8 ).
(With tyre pressure monitoring system)
After adjusting the tyre pressure,
initialization of the tyre pressure
monitoring system is necessary to make
the system operate normally.
Refer to Tyre Pressure Monitoring System
Initialization on page 4-143 .

NOTE

Always check tyre pressure when

tyres are cold.

Warm tyres normally exceed

recommended pressures. Do not
release air from warm tyres to adjust
the pressure.

Underin

À ation can cause reduced

fuel economy, uneven and
accelerated tyre wear, and poor
sealing of the tyre bead, which
will deform the wheel and cause
separation of tyre from rim.

Overin

À ation can produce a harsh

ride, uneven and accelerated tyre
wear, and a greater possibility of
damage from road hazards.

Keep your tyre pressure at the correct

levels. If one frequently needs
in

À ating, have it inspected.

Tyre Rotation

WARNING

Rotate tyres periodically:
Irregular tyre wear is dangerous. To
equalize tread wear for maintaining
good performance in handling and
braking, rotate the tyres every 10,000
km (6,250 miles), or sooner if irregular
wear develops.

During rotation, inspect them for correct
balance.

/:A

6–35

Maintenance and Care

Owner Maintenance

NOTE

Because your vehicle is not equipped
with a spare tyre, you cannot do a tyre
rotation safely with the jack that comes
with your vehicle. Have an expert
repairer, we recommend an Authorised
Mazda Repairer perform tyre rotation.

Do not include (TEMPORARY USE ONLY)
spare tyre in rotation.

Forward

Also, inspect them for uneven wear and
damage. Abnormal wear is usually caused
by one or a combination of the following:

Incorrect tyre pressure

Improper wheel alignment

Out-of-balance wheel

Severe braking

After rotation, in

À ate all tyre pressures to

speci

¿ cation (page 9-8 ) and inspect the

wheel nuts for tightness.
(With tyre pressure monitoring system)
After adjusting the tyre pressure,
initialization of the tyre pressure
monitoring system is necessary to make
the system operate normally.
Refer to Tyre Pressure Monitoring System
Initialization on page 4-143 .

CAUTION

Rotate unidirectional tyres and radial
tyres that have an asymmetrical tread
pattern or studs only from front to rear,
not from side to side. Tyre performance
will be reduced if rotated from side to
side.
(With limited-slip differential)
Do not use the following:

Tyres not of the designated size

Tyres of different sizes or types at the

same time

Tyres not suf

¿ ciently inÀ ated

If these instructions are not followed,
the rotation of the left and right wheels
will be different and will thus apply
a constant load on the limited-slip
differential.
This will cause a malfunction.

Replacing a Tyre

WARNING

Always use tyres that are in good
condition:
Driving with worn tyres is dangerous.
Reduced braking, steering, and traction
could result in an accident.

Replace all four tyres at the same time:
Replacing just one tyre is dangerous.
It could cause poor handling and poor
braking resulting in loss of vehicle
control. Mazda strongly recommends
that you replace all four tyres at the
same time.

*Some models.

If a tyre wears evenly, a wear indicator
will appear as a solid band across the
tread.
Replace the tyre when this happens.

New tread

Tread wear indicator

Worn tread

  You should replace the tyre before the
band crosses the entire tread.
(With tyre pressure monitoring system)
  After adjusting the tyre pressure,
initialization of the tyre pressure
monitoring system is necessary to make
the system operate normally.
  Refer to Tyre Pressure Monitoring System
Initialization on page 4-143 .

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:

Tyre

¿ t

Wheel and bearing life

Ground clearance

Snow-chain clearance

Speedometer calibration

Headlight aim

Bumper height

Tyre 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 expert

repairer, we recommend an
Authorised Mazda Repairer.

Proper tyre balancing provides the best
riding comfort and helps reduce tread
wear. Out-of-balance tyres can cause
vibration and uneven wear, such as
cupping and

À at spots.
