positioned properly before reinserting
the dipstick.
7. Reinsert the dipstick fully.
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:
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.
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.
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 –30 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.
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. Coolant reservoir
Cooling fa nCooling system cap
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. CAUTION 
Radiator coolant will damage paint.
Rinse it off quickly if spilled. 
Use only soft (demineralized) water in
the coolant mixture. Water that contains
minerals will cut down on the coolant's
effectiveness. 
Do not add only water. Always add a
proper coolant mixture. 
The engine has aluminum parts and
must be protected by an ethylene-glycol-
based coolant to prevent corrosion and
freezing. 
DO NOT USE coolants Containing
Alcohol, methanol, Borate or Silicate.
These coolants could damage the
cooling system. 
DO NOT MIX alcohol or methanol with
the coolant. This could damage the
cooling system. 
Do not use a solution that contains more
than 60% antifreeze.
This would reduce effectiveness. 
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 coolant reservoir is empty or new
coolant is required frequently, consult an
Authorized Mazda Dealer.

Owner Maintenance
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.
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. 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.
Using Washer Fluid Without Anti-freeze
Protection in Cold Weather:
Operating your vehicle in temperatures
below 4 degrees C (40 degrees 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
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 –32 Maintenance and Care
Owner Maintenance Inspect fluid level in the washer fluid
reservoir; add fluid if necessary.
Use plain water if washer fluid is
unavailable.
But use only washer fluid in cold weather
to prevent it from freezing. 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.

Wiper BladesCAUTION 
Hot waxes applied by automatic car
washers have been known to affect 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. 
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 fingers
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. Replacing Windshield Wiper
Blades When the wipers no longer clean well, the
blades are probably worn or cracked.
Replace them.
CAUTION To prevent damage to the wiper arms
and other components, do not try to
sweep the wiper arm by hand.
NOTE
When raising both windshield wiper arms,
raise the driver's side wiper arm first.
When lowering the wiper arms, slowly
lower the wiper arm from the passenger's
side first while supporting it with your
hand. Forcefully lowering the wiper arms
could damage the wiper arm and blade,
and may scratch or crack the windshield.
(Type A)
1. Raise the wiper arm.
2. Open the clip and slide the blade
assembly in the direction of the arrow.

from the arm.
CAUTION To prevent damage to the windshield
let the wiper arm down easily, do not
let it slap down on the windshield.
4. Pull down the blade rubber and slide it
out of blade holder.
5. Remove the metal stiffeners from each
blade rubber and install them in the
new blade. CAUTION 
Do not bend or discard the stiffeners. You
need to use them again. 
If the metal stiffeners are switched,
the blade's wiping efficiency could be
reduced.
So do not use the driver's side metal
stiffeners on the passenger's side, or vice
versa. 
Be sure to reinstall the metal stiffeners in
the new blade rubber so that the curve
is the same as it was in the old blade
rubber.
6. Carefully insert the new blade rubber.
Then install the blade assembly in the
reverse order of removal.
(Type B)
1. Raise the wiper arm and turn the blade
assembly to expose the plastic locking
clip.
Compress the clip and slide the
assembly downward; then lift it off the
arm.

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:
