▼Vehicle Engine Control Unit Reset Procedure
NOTE
This procedure is intended for vehicles with
the engine oil flexible maintenance setting
selected.
After replacing the engine oil, have a repair shop such as an A uthorized Mazda Dealer
perform the initialization (engine oil data resetting) of the r ecorded value. If the value
recorded by the computer is not initialized, the wrench indicator light may not turn off or it
may turn on earlier than normal.
NOTE
The initialization (engine oil data resetting) of the recorded value can be performed using
the following procedure:
1. Switch the ignition OFF.
2. Switch the ignition ON with the selector pressed, and press and hold the selector for
about 5 seconds until the master warning light
flashes.

3. After the master warning light flashes for several seconds, the initialization is
completed.

▼Inspecting Engine Oil Level
1. Be sure the vehicle is on a level
surface.
2. Warm up the engine to normal operating temperature.
3. Turn it off and wait at least 5 minutes for the oil to ret urn to the oil pan.
4. Pull out the dipstick, wipe it clean, and reinsert it fully.

MAX
MIN OK
5. Pull it out again and examine the level.
The level is normal if it is between the
MIN and MAX marks.
If it is near or below MIN, add enough
oil to bring the level to MAX.
CAUTION
Do not overfill the engine oil. This may
cause engine damage.
6. Make sure the O-ring on the dipstick is positioned properly before reinserting
the dipstick.
7. Reinsert the dipstick fully.
Engine Coolant
▼ Inspecting Coolant Level
WA R N I N G
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.
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 F and L marks on
the coolant reservoir when the engine is
cool.

Cooling system cap Coolant reservoir
Cooling fan
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.
CAUTION
 Radiator coolant will damage paint.
Rinse it off quickly if spilled.
 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 reserv oir is empty or new
coolant is required frequently, consult an
Authorized Mazda Dealer.

Brake/Clutch Fluid
▼Inspecting Brake/Clutch Fluid Level
WA R N I N G
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.
Window Washer Fluid
▼ Inspecting Washer Fluid Level
WA R N I N G
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.

Inspect fluid level in the washer fluid
reservoir; add fluid if necessary.
E

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.
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 Blades
CAUTION
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.
1. Raise the wiper arm.
2. Open the clip and slide the blade
assembly in the direction of the arrow.

3. Tilt the blade assembly and remove itfrom 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 eachblade 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 blad e assembly in the
reverse order of removal.
▼ Replacing Rear Window Wiper
Blade
When the wiper no longer cleans well, the
blade is probably worn or cracked.
Replace it.
CAUTION
To prevent damage to the wiper arm and
other components, do not move the wiper
by hand.
