Owner Maintenance

WARNING

Do not perform maintenance work if you lack suꢀcient knowledge and experience

or the proper tools and equipment to do the work. Have maintenance work done by a

qualiꢁed technician:

Performing maintenance work on a vehicle is dangerous if not done properly. You can be

seriously injured while performing some maintenance procedures.

If you must run the engine while working under the hood, make certain that you

remove all jewelry (especially rings, bracelets, watches, and necklaces) and all

neckties, scarves, and similar loose clothing before getting near the engine or cooling

fan which may turn on unexpectedly:

Working under the hood with the engine running is dangerous. It becomes even more

dangerous when you wear jewelry or loose clothing.

Either can become entangled in moving parts and result in injury.

Switch the ignition to oꢂ and make sure the fan is not running before attempting

to work near the cooling fan:

Working near the cooling fan when it is running is dangerous. The fan could continue

running indeꢀnitely even if the engine has stopped and the engine compartment

temperature is high. You could be hit by the fan and seriously injured.

Do not leave items in the engine compartment:

After you have ꢀnished checking or doing servicing in the engine compartment, do not

forget and leave items such as tools or rags in the engine compartment.

Tools or other items left in the engine compartment could cause engine damage or a ꢀre

leading to an unexpected accident.

engine has been running, parts of the

engine compartment can become very

hot. You could be burned. Carefully

inspect the engine coolant in the

coolant reservoir, but do not open it.

Switch the ignition to oꢂ and make

sure the fan is not running before

attempting to work near the cooling

fan:

Working near the cooling fan when it

is running is dangerous. The fan could

continue running indeꢀnitely even if

the engine has stopped and the engine

compartment temperature is high. You

could be hit by the fan and seriously

injured.

Do not remove either cooling

system cap when the engine and

radiator are hot:

When the engine and radiator are hot,

scalding coolant and steam may shoot

out under pressure and cause serious

injury.

NOTE

Changing the coolant should be done by

an Authorized Mazda Dealer.

6

–29

Maintenance and Care

Owner Maintenance

Inspect the antifreeze protection and

coolant level in the coolant reservoir at

least once a year—at the beginning of the

winter season—and before traveling where

temperatures may drop below freezing.

CAUTION

ꢀ¾ꢀ

Radiator coolant will damage paint.

Rinse it oꢂ quickly if spilled.

ꢀ

ꢀ¾ꢀ

Use only soft (demineralized) water in

the coolant mixture. Water that contains

minerals will cut down on the coolant's

eꢂectiveness.

Inspect the condition and connections of

all cooling system and heater hoses.

Replace any that are swollen or

deteriorated.

ꢀ¾ꢀ

Do not add only water. Always add a

proper coolant mixture.

ꢀ¾ꢀ

The engine has aluminum parts and

must be protected by an ethylene-glycol-

based coolant to prevent corrosion and

freezing.

The coolant should be at full in the

radiator and between the F and L marks

on the coolant reservoir when the engine

is cool.

ꢀ¾ꢀ

DO NOT USE coolants Containing

Alcohol, methanol, Borate or Silicate.

These coolants could damage the

cooling system.

ꢀ

ꢀ¾ꢀ

DO NOT MIX alcohol or methanol with

the coolant. This could damage the

cooling system.

ꢀ¾ꢀ

Do not use a solution that contains more

than 60% antifreeze.

This would reduce eꢂectiveness.

ꢀ

NOTE

If the “FL22” mark is shown on or near

the cooling system cap, it is recommended

to use Mazda Genuine FL22 engine

coolant.

If it is at or near L, add enough coolant to

the coolant reservoir to provide freezing

and corrosion protection and to bring the

level to F.

Securely tighten the coolant reservoir tank

cap after adding coolant.

If the coolant reservoir is empty or new

coolant is required frequently, consult an

Authorized Mazda Dealer.

Brake/Clutch Fluid

Washer Fluid

Inspecting Washer Fluid Level

WARNING

Inspecting Brake/Clutch Fluid

Level

WARNING

Use only windshield washer ꢃuid or

plain water in the reservoir:

Using radiator antifreeze as washer

ꢁuid is dangerous. If sprayed on the

windshield, it will dirty the windshield,

aꢂect your visibility, and could result in

an accident.

If the brake/clutch ꢃuid level is low, have

the brakes inspected:

A low brake/clutch ꢁuid level is

dangerous.

A low level could indicate brake lining

wear or a brake system leak which

could cause the brakes to fail and lead

to an accident.

Using Washer Fluid Without Anti-freeze

Protection in Cold Weather:

The brakes and clutch draw ﬂuid from the

same reservoir.

Inspect the ﬂuid level in the reservoir

regularly. It should be kept between the

MAX and MIN lines.

The level normally drops with

accumulated distance, a condition

associated with wear of brake and clutch

linings. If it is excessively low, have

the brake/clutch system inspected by an

Authorized Mazda Dealer.

Operating your vehicle in temperatures

below 4 degrees C (40 degrees F)

using washer ꢁuid without anti-freeze

protection is dangerous as it could

cause impaired windshield vision and

result in an accident. In cold weather,

always use washer ꢁuid with anti-

freeze protection.

NOTE

State or local regulations may restrict the

use of volatile organic compounds (VOCs),

which are commonly used as anti-freeze

agents in washer ﬂuid. A washer ﬂuid with

limited VOC content should be used only

if it provides adequate freeze resistance

for all regions and climates in which the

vehicle will be operated.

6

–31

Maintenance and Care

Owner Maintenance

Inspect ﬂuid level in the washer ﬂuid

reservoir; add ﬂuid if necessary.

Body Lubrication

All moving points of the body, such as

door and hood hinges and locks, should

be lubricated each time the engine oil is

changed. Use a nonfreezing lubricant on

locks during cold weather.

Make sure the hood's secondary latch

keeps the hood from opening when the

primary latch is released.

L

Use plain water if washer ﬂuid is

unavailable.

But use only washer ﬂuid in cold weather

to prevent it from freezing.

NOTE

Front and rear washer ﬂuid is supplied

from the same reservoir.

Tire Inﬂation Pressure

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.

WARNING

Always inꢃate the tires to the correct

pressure:

Overinꢁation or underinꢁation of tires

is dangerous. Adverse handling or

unexpected tire failure could result in a

serious accident.

WARNING

Using Diꢂerent Tire Types:

Refer to Tires on page 9-10.

Driving your vehicle with diꢂerent

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.

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.

Using Wrong-Sized Tires:

Using any other tire size than what is

speciꢀed for the vehicle (page 9-10)

is dangerous. It could seriously aꢂect

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 speciꢀed for the

vehicle.

Inspect all tire pressures monthly

(including the spare) when the tires are

cold. Maintain recommended pressures for

the best ride, handling, and minimum tire

wear.

Refer to the speciﬁcation charts (page

9-10).

After adjusting the tire pressure,

initialization of the tire pressure

monitoring system is necessary to make

the system operates normally.

Refer to Tire Pressure Monitoring System

Initialization on page 4-106.

Maintenance and Care

Owner Maintenance

NOTE

During rotation, inspect them for correct

balance.

^ꢀyꢀAlways check tire pressure when tires

are cold.

^ꢀyꢀWarm tires normally exceed

recommended pressures. Do not release

air from warm tires to adjust the

pressure.

^ꢀyꢀUnderinﬂation 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.

^ꢀyꢀOverinﬂation can produce a harsh ride,

uneven and accelerated tire wear, and a

greater possibility of damage from road

hazards.

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:

^ꢀKeep your tire pressure at the correct

levels. If one frequently needs inﬂating,

have it inspected.

ꢀyꢀ

Incorrect tire pressure

ꢀyꢀ

Improper wheel alignment

Tire Rotation

ꢀyꢀ

Out-of-balance wheel

ꢀyꢀ

Severe braking

WARNING

Rotate tires periodically:

After rotation, inﬂate all tire pressures to

speciﬁcation (page 9-10) and inspect the

lug nuts for tightness.

After adjusting the tire pressure,

initialization of the tire pressure

monitoring system is necessary to make

the system operates normally.

Irregular tire wear is dangerous. To

equalize tread wear for maintaining

good performance in handling and

braking, rotate the tires every 12,000

km (7,500 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 on

page 6-4.

Refer to Tire Pressure Monitoring System

Initialization on page 4-106.

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.

Maintenance and Care

Owner Maintenance

NOTE

Replacing a Tire

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.

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.

Refer to Tire Labeling on page 8-24.

Temporary Spare Tire

Inspect the temporary spare tire at least

monthly to make sure it is properly

inﬂated and stored.

If a tire wears evenly, a wear indicator will

appear as a solid band across the tread.

Replace the tire when this happens.

NOTE

Tread wear indicator

The temporary spare tire condition

gradually deteriorates even if it has not

been used.

The temporary spare tire is easier to

handle because of its construction which

is lighter and smaller than a conventional

tire. This tire should be used only for an

emergency and only for a short distance.

New tread

Worn tread

Use the temporary spare tire only until the

conventional tire is repaired, which should

be as soon as possible.

You should replace the tire before the band

crosses the entire tread.

Refer to Tires on page 9-10.

After adjusting the tire pressure,

initialization of the tire pressure

monitoring system is necessary to make

the system operates normally.

Refer to Tire Pressure Monitoring System

Replacing a Wheel

CAUTION

ꢀ¾ꢀ

Do not use your temporary spare tire

rim with a snow tire or a conventional

tire. Neither will properly ꢀt and could

damage both tire and rim.

WARNING

Always use wheels of the correct size on

your vehicle:

Using a wrong-sized wheel is

dangerous. Braking and handling

could be aꢂected, leading to loss of

control and an accident.

ꢀ¾ꢀ

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.

ꢀ¾ꢀ

The temporary spare tire is for limited

use, however, if the tread wear solid-

NOTE

ꢀ¾ꢀ

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.

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).

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.

Refer to Tire Labeling on page 8-24.

Replacing Exterior Light Bulbs

WARNING

Headlights (With xenon fusion

headlights)

Do not replace the xenon fusion bulbs

yourself:

Replacing the xenon fusion bulbs

yourself is dangerous. Because the

xenon fusion bulbs require high

voltage, you could receive an electric

shock if the bulbs are handled

incorrectly. Consult an Authorized

Mazda Dealer when the replacement is

necessary.

Low/High beam bulbs

You cannot replace the low/high beam

bulbs by yourself. The bulbs must be

replaced at an Authorized Mazda Dealer.

Headlights (With halogen headlights)

the engine, turn the steering wheel all

the way to the left, and turn off engine.

If you are changing the left bulb, turn

the steering wheel to the right, and turn

pressurized gas. If one is broken, it will

explode and serious injuries could be

caused by the ꢁying glass.

2. Make sure the headlight switch is off.

3. Pull the center of each plastic retainer

and remove the retainers.

If the glass portion is touched with

bare hands, body oil could cause the

bulb to overheat and explode when lit.

Removal

Always keep halogen bulbs out of the

reach of children:

Playing with a halogen bulb is

dangerous. Serious injuries could be

caused by dropping a halogen bulb or

breaking it some other way.

Installation

NOTE

^ꢀyꢀTo replace the bulb, contact an

Authorized Mazda Dealer.

^ꢀyꢀIf the halogen bulb is accidentally

touched, it should be cleaned with

rubbing alcohol before being used.

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

4. Inspect the fuse and replace it if it is

blown.

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.

Blown

Normal

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 OUTLET circuit.

CAUTION

Always replace a fuse with a genuine

Mazda fuse or equivalent of the same

rating. Otherwise you may damage

the electric system.

Have an Authorized Mazda Dealer

perform the replacement:

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:

Replacing these fuses by yourself is

dangerous because they are high

current fuses. Incorrect replacement

could cause an electrical shock or a

short circuit resulting in a ꢀre.

1. Make sure the ignition is switched off,

and other switches are off.

2. Remove the fuse block cover.

4. Reinstall the cover and make sure that

it is securely installed.

3. If any fuse but the MAIN fuse is

blown, replace it with a new one of the

same amperage rating.
