Owner Maintenance
Owner Maintenance PrecautionsThe owner or a qualified service technician should make these ve hicle inspections at the
indicated intervals to ensure safe and dependable operation.
Bring any problem to the attention of an Authorized Mazda Dealer or qualified service
technician as soon as possible.
When Refueling 
Brake and clutch fluid level (page 6-31 )

At Least Twice a Year (For Example, Every Spring and Fall)
You can do the following scheduled maintenance items if you have some mechanical ability
and a few basic tools and if you closely follow the directions in this manual. 
Engine coolant (page 6-29 )

Improper or incomplete service may result in problems. This section gives instructions only
for items that are easy to perform.
As explained in the Introduction (page 6-2 ), several procedures can be done only by a
qualified service technician with special tools.
Improper owner maintenance during the warranty period may affect warranty coverage.
Refer to Introduction (page 6-2 ) for owner's responsibility in protecting your investment.
For details, read the separate Mazda Warranty statement provided with the vehicle. If you
are unsure about any servicing or maintenance procedure, have it done by an Authorized
Mazda Dealer.
There are strict environmental laws regarding the disposal of w aste oil and fluids. Please
dispose of your waste properly and with due regard to the environment.
We recommend that you entrust the oil and fluid changes of your vehicle to an Authorized
Mazda Dealer.

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.
