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 above.
CAUTION
  Using oils of viscosity besides those recommended for specifi c temperature ranges
could result in engine damage.
 
(SKYACTIV-D 1.5) SKYACTIV-D 1.5 uses specifi ed oil. Please confi rm the specifi cation in owner's
manual. If engine oil other than the specifi ed oil is used, the Diesel Particulate Filter
effective period of use will be shortened or the Diesel Particulate Filter may be
damaged.

NOTE
(SKYACTIV-G 2.0)
 
 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/1000 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.
(SKYACTIV-D 1.5)
 
 Whenever the engine oil is replaced, the vehicles engine control unit needs to be
reset as soon as possible. Otherwise the wrench indicator light or engine oil warning
light may turn on. To reset the engine control unit, consult an expert repairer, we
recommend an Authorised Mazda Repairer or refer to the vehicle engine control unit
reset procedure on page 6-27 .
 Inspect the engine oil level periodically. When inspecting the engine oil, if the engine
oil level is exceeds the “X” mark on the dipstick, replace the engine oil. This should
be done by an expert repairer, we recommend an Authorised Mazda Repairer. When
replacing the engine oil, inspect the oil level using the oil dipstick and refi ll so that the
engine oil level is within the range between Full to Low as shown in the fi gure.

NOTE
(SKYACTIV-D 1.5)
When inspecting the engine oil level,
pull out the dipstick straight without
twisting. In addition, when inserting
the dipstick, always insert it without
twisting so that the “X” mark faces the
front of the vehicle.

The level is normal if it is between
Low and Full.
If it is near or below Low, add enough
oil to bring the level to Full.
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.
Switch the ignition to 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.
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 F or FULL 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 or 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.
CAUTION
  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 expert repairer, we recommend an
Authorised Mazda Repairer.

Washer Fluid
Inspecting Washer Fluid Level
WARNING
Use only windscreen washer fl uid or
plain water in the reservoir:
Using radiator antifreeze as washer
fl uid is dangerous. If sprayed on the
windscreen, it will dirty the windscreen,
affect your visibility, and could result in
an accident.
Inspect fl uid level in the washer fl uid
reservoir; add fl uid if necessary.
E

Use plain water if washer fl uid is
unavailable.
But use only washer fl uid in cold weather
to prevent it from freezing.
NOTE
Front and rear washer fl uid is supplied
from the same reservoir.
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.

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 fl 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 overfi ll.
Examine the specifi 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 fi 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 Dealer for a
battery replacement purchase.
