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.

MAXOK
MIN
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
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.

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 F and L marks
on the coolant reservoir when the engine
is cool.
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.
 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.

Maintenance and Care
Appearance Care
*Some models.
Pay special attention to these areas
because they easily hide mud and dirt.
It will do more harm than good to wet
down the road grime without removing
it.
The lower edges of doors, rocker panels,
and frame members have drain holes that
should not be clogged. Water trapped there
will cause rusting.
WARNING
Dry off brakes that have become
wet by driving slowly, releasing the
accelerator pedal and lightly applying
the brakes several times until the brake
performance returns to normal:Driving with wet brakes is dangerous.
Increased stopping distance or the
vehicle pulling to one side when
braking could result in a serious
accident. Light braking will indicate
whether the brakes have been affected.
Aluminum Wheel Maintenance*
A protective coating is provided over the
aluminum wheels. Special care is needed
to protect this coating.
CAUTION
Do not use any detergent other than
mild detergent. Before using any
detergent, verify the ingredients.
Otherwise, the product could discolor
or stain the aluminum wheels.
NOTE
 Do not use a wir e brush or any abrasive
cleaner, polishing compound, or solvent
on aluminum wheels. They may damage
the coating.
 Always use a sponge or soft cloth to
clean the wheels.
Rinse the wheels thor oughly with
lukewarm or cold water. Also, be sure
to clean the wheels after driving on
dusty or salted roads to help prevent
corrosion.
 Avoid washing your vehicle in an
automatic car wash that uses high-
speed or hard brushes.
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.

If Trouble Arises
Overheating
Overheating
If the high engine coolant temperature
warning light illuminates, 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 illuminates:
1. Drive safely to the side of the road and
park off the right-of-way.
2. Put a vehicle with an automatic
transaxle in park (P), a manual
transaxle 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.
