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 return to the oil pan.
4. Pull out the dipstick, wipe it clean, and
reinsert it fully.


MAX
MINOK

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 overfi ll 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
WARNING
Do not use a match or live fl ame 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 indefi nitely 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.

N O T E
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
 


¾ Radiator coolant will damage paint.
 Rinse it off quickly if spilled. 



¾ Use only soft (demineralized) water in
the coolant mixture. Water that contains
minerals will cut down on the coolant's
eff ectiveness.




¾ Do not add only water. Always add a
proper coolant mixture.
 


¾ The engine has aluminum parts and
must be protected by an ethylene-glycol-
based coolant to prevent corrosion and
freezing.
 


¾ DO NOT USE coolants Containing
Alcohol, methanol, Borate or Silicate.
  These coolants could damage the
cooling system.
 


¾ DO NOT MIX alcohol or methanol with
the coolant. This could damage the
cooling system.
 


¾ Do not use a solution that contains more
than 60% antifreeze.
  This would reduce eff ectiveness. 



¾ 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.

Brake Fluid
Inspecting Brake Fluid Level
WARNING
If the brake fl uid level is low, have the
brakes inspected:
A low brake fl 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.

Inspect the À uid 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 linings. If it
is excessively low, have the brake system
inspected by an Authorized Mazda Dealer.


Window Washer Fluid
Inspecting Washer Fluid Level
WARNING
Use only windshield washer fl uid or
plain water in the reservoir:
Using radiator antifreeze as washer
fl uid is dangerous. If sprayed on the
windshield, it will dirty the windshield,
aff ect 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 fl 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 fl uid with anti-
freeze protection.

N O T E
State or local regulations may restrict the
use of volatile organic compounds (VOCs),
which are commonly used as anti-freeze
agents in washer À uid. A washer À uid 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 À uid level in the washer À uid
reservoir; add À uid if necessary.

E

Use plain water if washer À uid is
unavailable.
But use only washer À uid in cold weather
to prevent it from freezing.
N O T E
Front and rear washer À uid 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
 


¾ Hot waxes applied by automatic car
washers have been known to aff ect the
wiper's ability to clean windows.
 


¾ To prevent damage to the wiper blades,
do not use gasoline, kerosene, paint
thinner, or other solvents on or near
them.
 


¾ When the wiper lever is in the AUTO
position and the ignition is switched ON,
the wipers may move automatically in
the following cases:
 


¾ If the windshield above the rain
sensor is touched.
 


¾ If the windshield above the rain
sensor is wiped with a cloth.
 


¾ If the windshield is struck with a hand
or other object.
 


¾ If the rain sensor is struck with a hand
or other object from inside the vehicle.
  Be careful not to pinch hands or fi 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.
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.

N O T E
When raising both windshield wiper arms,
raise the driver's side wiper arm ¿ rst.
When lowering the wiper arms, slowly
lower the wiper arm from the passenger's
side ¿ rst while supporting it with your
hand. Forcefully lowering the wiper arms
could damage the wiper arm and blade,
