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.

Engine Coolant

Inspecting Coolant Level

▼

WARNING

Do not use a match or live ﬂame in

the engine compartment. DO NOT

ADD COOLANT WHEN THE ENGINE

IS HOT:

Inspect the condition and connections

of all cooling system and heater hoses.

Replace any that are swollen or

deteriorated.

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.

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 oﬀ 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 indeﬁnitely even if

the engine has stopped and the engine

compartment temperature is high. You

could be hit by the fan and seriously

injured.

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.

CAUTION

Radiator coolant will damage paint.

Rinse it oﬀ quickly if spilled.

NOTE

Changing the coolant should be done

by an Authorized Mazda Dealer.

6-17

O^Maiw^ntenn^ane^cer^anM^{d C}a^areintenance

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.

Brake/Clutch Fluid

Inspecting Brake/Clutch Fluid

Level

▼

WARNING

If the brake/clutch ﬂuid level is low,

have the brakes inspected:

A low brake/clutch ﬂuid 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.

If the coolant reservoir is empty or new

coolant is required frequently, consult

an Authorized Mazda Dealer.

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.

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 ﬂuid or

plain water in the reservoir:

Using radiator antifreeze as washer

ﬂuid is dangerous. If sprayed on the

windshield, it will dirty the windshield,

aﬀect your visibility, and could result in

an accident.

The top of the ﬂoat should be between

F and E.

Using Washer Fluid Without

Anti-freeze Protection in Cold

Weather:

Use plain water if washer ﬂuid is

unavailable.

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 ﬂuid

without anti-freeze protection is

dangerous as it could cause impaired

windshield vision and result in an

accident. In cold weather, always use

washer ﬂuid with anti-freeze

protection.

NOTE

Front and rear washer ﬂuid is supplied

from the same reservoir.

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.

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.

10.Insert the tabs of the lower cover

into the slots of the transmitter and

Using Wrong-Sized Tires:

Using any other tire size than what is

speciﬁed for the vehicle (page 9-7)

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

▼

WARNING

Always inﬂate the tires to the correct

CAUTION

You should replace the tire before the

band crosses the entire tread.

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.

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.

Replacing a Tire

▼

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.

Refer to Tire Labeling on page 8-22.

Replace all four tires at the same

time:

Temporary Spare Tire

▼

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.

Inspect the temporary spare tire at

least monthly to make sure it is

properly inﬂated and stored.

NOTE

The temporary spare tire condition

gradually deteriorates even if it has not

been used.

If a tire wears evenly, a wear indicator

will appear as a solid band across the

tread.

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.

Replace the tire when this happens.

Use the temporary spare tire only until

the conventional tire is repaired, which

should be as soon as possible.

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.

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.



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 8-22.

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.

All the light bulbs are the LED type.

The LED bulb cannot be replaced as a

single unit because it is an integrated

unit.

The LED bulb has to be replaced with

the unit. We recommend an

Authorized Mazda Dealer when the

replacement is necessary.

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.

circuit not essential to vehicle

operation, such as the audio or

accessory socket circuit.

1. Normal

CAUTION

Always replace a fuse with a

genuine Mazda fuse or equivalent

of the same rating. Otherwise you

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.
