Owner Maintenance

WARNING

Do not perform maintenance workif you lacksuꢀcient knowledge and experience or the

proper tools and equipment to do the work. Have maintenance workdone 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, loose clothing or have long hair or a long beard.

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

Pull over to a safe location, then switch the ignition oꢂ and make sure the fan is not

running before attempting to worknear 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.

NOTE

Engine Coolant

Changing the coolant should be done by

an Authorized Mazda Dealer.

Inspecting Coolant Level

▼

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.

WARNING

Do not use a match or live ꢃame in the

engine compartment. DO NOT ADD

COOLANT WHEN THE ENGINE IS HOT:

A hot engine is dangerous. If the 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.

Inspect the condition and connections of

all cooling system and heater hoses.

Replace any that are swollen or

deteriorated.

The coolant should be at full in the

radiator and between the FULL and LOW

marks on the coolant reservoir when the

engine is cool.

Pull over to a safe location, then switch

the ignition oꢂ and make sure the fan is

not running before attempting to work

near the cooling fan:

Cooling system cap

Coolant reservoir

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.

Cooling fan

If it is at or near LOW, add enough coolant

to the coolant reservoir to provide freezing

and corrosion protection and to bring the

level to FULL.

Securely tighten the coolant reservoir tank

cap after adding coolant.

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.

Maintenance and Care

Owner Maintenance

Brake/Clutch Fluid

CAUTION

Inspecting Brake/Clutch Fluid Level

▼

Radiator coolant will damage paint.

Rinse it oꢂ quickly if spilled.

WARNING

If the “FL22” mark is shown on or near

the cooling system cap, use of FL-22 is

recommended when replacing engine

coolant. Using engine coolant other than

FL-22 may cause serious damage to the

engine and cooling system.

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.

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.

If the coolant reservoir is empty or new

coolant is required frequently, consult an

Authorized Mazda Dealer.

6-26

Maintenance and Care

Owner Maintenance

Inspect fluid level in the washer fluid

reservoir; add fluid if necessary.

Washer Fluid

Inspecting Washer 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.

Use plain water if washer fluid is

unavailable.

Using Washer Fluid Without Anti-freeze

Protection in Cold Weather:

But use only washer fluid in cold weather

to prevent it from freezing.

Operating your vehicle in temperatures

below 4 °C (40 °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.

6-27

Maintenance and Care

Owner Maintenance

Body Lubrication

Wiper Blades

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.

CAUTION

Hot waxes applied by automatic car

washers have been known to aꢂect the

wiper's ability to clean windows.

To prevent damage to the wiper blades,

do not use gasoline, kerosene, paint

thinner, or other solvents on or near

them.

Make sure the hood's secondary latch

keeps the hood from opening when the

primary latch is released.

When the wiper lever is in the AUTO

position and the ignition is switched ON,

the wipers may move automatically in

the following cases:

If the windshield above the rain sensor

is touched.

If the windshield above the rain sensor

is wiped with a cloth.

If the windshield is struck with a hand

or other object.

If the rain sensor is struck with a hand

or other object from inside the vehicle.

Be careful not to pinch hands or ꢀngers

as it may cause injury, or damage the

wipers. When washing or servicing the

vehicle, make sure the wiper lever is in

the OFF position.

Contamination of either the windshield or

the blades with foreign matter can reduce

wiper effectiveness. Common sources are

insects, tree sap, and hot wax treatments

used by some commercial car washes.

If the blades are not wiping properly, clean

the window and blades with a good

cleaner or mild detergent; then rinse

thoroughly with clean water. Repeat if

necessary.

WARNING

10. Insert the tabs of the lower cover into

the slots of the transmitter and install

the lower cover.

Using Diꢂerent Tire Types:

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.

Using Wrong-Sized Tires:

Using any other tire size than what is

speciꢀed for the vehicle (page 9-8) 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.

Tire Inflation Pressure

▼

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.

Refer to Tires on page 9-8.

6-38

Maintenance and Care

Owner Maintenance

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.

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 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.

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 specification charts (page

9-8).

Refer to Scheduled Maintenance on page

6-4.

NOTE



Always check tire pressure when tires

are cold.

Warm tires normally exceed

▼

WARNING



Incorrect tire pressure

Improper wheel alignment

Out-of-balance wheel

Severe braking

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.

After rotation, inflate all tire pressures to

specification (page 9-8) 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.

If a tire wears evenly, a wear indicator will

appear as a solid band across the tread.

Replace the tire when this happens.

Tread wear indicator

(With limited-slip diꢂerential)

Do not use the following:

Tires not of the designated size

Tires of diꢂerent sizes or types at the

same time

Tires not suꢃciently inꢁated

If these instructions are not followed, the

rotation of the left and right wheels will be

diꢂerent and will thus apply a constant

load on the limited-slip diꢂerential.

This will cause a malfunction.

New tread

Worn tread

You should replace the tire before the band

crosses the entire tread.

6-40

Maintenance and Care

Owner Maintenance

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.



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.

Refer to Tire Labeling on page 8-25.

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 aꢂected,

leading to loss of control and an accident.

CAUTION

A wrong-sized wheel may adversely aꢂect:

Tire ꢀt

element will be melted.

4. Inspect the fuse and replace it if it is

blown.

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.

Blown

Normal

1. Make sure the ignition is switched off,

and other switches are off.

2. Open the fuse panel cover.

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.

6. Reinstall the cover and make sure that

it is securely installed.

Replacing the fuses under the hood

3. Remove the cover while lifting it

and sliding it to the rear.

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.

NOTE

If the lock is forcefully opened, the fuse

block cover may come in contact with

the frame when it is removed and

become scratched.

When removing the cover, remove it

slowly according to the following

procedure.

1. Disengage the rear lock by

pressing down on the front tab with

your fingers.

Normal

Blown

2. Remove the front tab while slightly

lifting the front of the cover.

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

ꢀre.

4. Reinstall the cover and make sure that

it is securely installed.
