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.

6 –68 Maintenance and Care
Appearance Care Plastic Part Maintenance 
When cleaning the plastic lenses of the
lights, do not use gasoline, kerosene,
rectified spirit, paint, thinner, highly
acidic detergents, or strongly alkaline
detergents. Otherwise, these chemical
agents can discolor or damage the
surfaces resulting in a significant loss
in functionality. If plastic parts become
inadvertently exposed to any of these
chemical agents, flush with water
immediately. 
If plastic parts such as the bumpers
become inadvertently exposed to
chemical agents or fluids such as
gasoline, oil, engine coolant, or battery
fluid, it could cause discoloration,
staining, or paint peeling. Wipe off any
such chemical agents or fluids using a
soft cloth immediately. 
High water temperature and high water
pressure car washers are available
depending on the type of high pressure
car washer device. If the car washer
nozzle is put too close to the vehicle or
aimed at one area for an extended period
of time, it could deform plastic parts or
damage the paint. 
Do not use wax containing compounds
(polish). Otherwise, it could result in
paint damage. 
In addition, do not use an electrical or
air tool to apply wax. Otherwise, the
frictional heat generated could result
in deformation of plastic parts or paint
damage. Interior Care WARNING Do not spray water into the vehicle
cabin:
Spraying water into the vehicle cabin is
dangerous as electrical devices such as
the audio and switches could get wet
resulting in a malfunction or vehicle
fire.
NOTE 
Do not wipe the interior using alcohol,
chlorine bleach, or organic solvents
such as thinner, benzene, and gasoline.
Otherwise, it may cause discoloration
or stains. 
Rubbing hard with a stiff brush or cloth
may cause damage.
If the vehicle interior becomes soiled
by any of the following, wipe it off
immediately using a soft cloth.
Leaving it uncleaned could cause
discoloration, stains, cracks, or peeling
of the coating, and it will make it hard to
wipe off later. 
Beverage or fragrance 
Grease or oil 
Soiling
Seat Belt Maintenance
1. Clean the soiled area by lightly dabbing
it with a soft cloth soaked in a mild
detergent (approx. 5%) diluted with
water.
2. Wipe off the remaining detergent using
a cloth soaked in clean water and
wrung out well.
3. Before retracting seat belts which have
been pulled out for cleaning, dry them
off thoroughly and make sure there is
no remaining moisture on them.

7 –27 If Trouble Arises
Overheating
OverheatingIf the high engine coolant temperature
warning light turns on, the vehicle loses
power, or you hear a loud knocking or
pinging noise, the engine is probably too
hot.
WARNING 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.
Open the hood ONLY after steam is no
longer escaping from the engine:
Steam from an overheated engine is
dangerous. The escaping steam could
seriously burn you. If the high engine coolant temperature
warning light turns on:
1. Drive safely to the side of the road and
park off the right-of-way.
2. Put a vehicle with an automatic
transmission in park (P), a manual
transmission in neutral.
3. Apply the parking brake.
4. Turn off the air conditioner.
5. Check whether coolant or steam is
escaping from the engine compartment.

If steam is coming from the engine
compartment:
Do not go near the front of the vehicle.
Stop the engine.
Wait until the steam dissipates, then
open the hood and start the engine.

If neither coolant nor steam is
escaping:
Open the hood and idle the engine until
it cools.
CAUTION If the cooling fan does not operate
while the engine is running, the engine
temperature will increase. Stop the
engine and call an Authorized Mazda
Dealer.
6. Make sure the cooling fan is operating,
then turn off the engine after the
temperature has decreased.
7. When cool, check the coolant level.
If it is low, look for coolant leaks from
the radiator and hoses.
