Engine oil viscosity, or thickness, has an effect on fuel economy and cold-weather operation
(starting and oil À ow).
Low-viscosity engine oils can provide improved fuel economy and cold-weather
performance.
When choosing an oil, consider the temperature range your vehicle will operate in before
the next oil change.
Then select the recommended viscosity from the chart.
CAUTION
Using oils of viscosity besides those recommended for speci ¿ c temperature ranges could
result in engine damage.
NOTE
It is normal for all engines to consume engine oil under normal driving conditions.
Engine oil consumption may be as high as 0.8 L/1,000 km (1 L/800 miles). This may
be as a result of evaporation, internal ventilation or burning of the lubricating oil in the
working engine. Oil consumption may be higher when the engine is new due to the
running-in process. Oil consumption is also dependant on engine speed and engine load.
Under extreme driving conditions, oil consumption may be higher.

Vehicle Engine Control Unit Reset Procedure
NOTE
This procedure is intended for vehicles with the engine oil À exible maintenance setting
selected.
After replacing the engine oil, have a repair shop such as an Authorised Mazda Repairer
perform the initialization (engine oil data resetting) of the recorded 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
À ashes.

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 sump.
4. Pull out the dipstick, wipe it clean, and
reinsert it fully.
MIN MAX
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 over ¿ 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 À 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 inde ¿ 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.

NOTE
Changing the coolant should be done
by an expert repairer, we recommend an
Authorised Mazda Repairer.
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 travelling
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 fan
Cooling 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 (demineralised) 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 aluminium 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.

Body Lubrication
All moving points of the body, such as
door and bonnet 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 bonnet's secondary latch
keeps the bonnet 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 petrol, paraf ¿ n,
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 windscreen above the rain
sensor is touched.
If the windscreen above the rain
sensor is wiped with a cloth.
If the windscreen 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
¿ 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 windscreen 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.

Battery Maintenance
To get the best service from a battery:
Keep it securely mounted.
Keep the top clean and dry.
Keep terminals and connections clean,
tight, and coated with petroleum jelly or
terminal grease.
Rinse off spilled electrolyte immediately
with a solution of water and baking
soda.
If the vehicle will not be used for an
extended time, disconnect the battery
leads and charge the battery every six
weeks.
Inspecting Electrolyte Level
A low level of electrolyte À uid will cause
the battery to discharge quickly.
Upper level
Lower level
Inspect the electrolyte level at least once
a week. If it is low, remove the caps and
add enough distilled water to bring the
level between the upper and lower level
(illustration).
Do not over ¿ ll.
Examine the speci ¿ c gravity of the
electrolyte with a hydrometer, especially
during cold weather. If it is low, recharge
the battery.
Battery Recharging
NOTE
Before performing maintenance or
recharging the battery, turn off all
accessories and stop the engine.
To disconnect the battery, remove the
negative lead ¿ rst. Install it last when
connecting the battery.
Be sure to remove the caps before
recharging the battery.
(With i-stop system) Do not quick-charge the battery.
If the battery quickly discharges
because, for example, the lights were
left on too long with the engine off,
slow-charge it as required by battery
size and charger capacity.
If the battery gradually discharges
because of high electric load while the
vehicle is being used, recharge it as
required by battery size and charger
capacity.
Battery Replacement
Contact an Authorised Mazda Repairer for
a battery replacement purchase.
