Engine oil viscosity, or thickness, has an effect on fuel economy and cold-weather operation
(starting and oil fl 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 above.
CAUTION
  Using oils of viscosity besides those recommended for specifi c temperature ranges
could result in engine damage.
 
(SKYACTIV-D 2.2) SKYACTIV-D 2.2 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
(MZR 1.6, SKYACTIV-G 1.5 and 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 2.2)
 
 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 6-28 .
  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.

Vehicle Engine Control Unit Reset Procedure
NOTE
This procedure is intended for vehicles with SKYACTIV-D 2.2 and vehicles with
SKYACTIV-G 1.5 or SKYACTIV-G 2.0 which the engine oil fl exible maintenance setting
is 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
fl ashes.

3. After the master warning light fl ashes for several seconds, the initialization is
completed.

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.

NOTE
(SKYACTIV-D 2.2)
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.
5. Pull it out again and examine the level.
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 and L marks
on the coolant reservoir when the engine
is cool.

SKYACTIV-G 2.0

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 (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.
CAUTION
  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 expert repairer, we recommend an
Authorised Mazda Repairer.

Brake/Clutch Fluid
Inspecting Brake/Clutch Fluid
Level
WARNING
If the brake/clutch fl uid level is low,
have the brakes inspected:
A low brake/clutch fl uid level is
dangerous.
A low level could indicate brake lining
wear or a brake system leak which
could cause the brakes to fail and lead
to an accident.
The brakes and clutch draw fl uid from the
same reservoir.
Inspect the fl uid level in the reservoir
regularly. It should be kept between the
MAX and MIN lines.
The level normally drops with
accumulated distance, a condition
associated with wear of brake and clutch
linings. If it is excessively low, have the
brake/clutch system inspected by an expert
repairer, we recommend an Authorised
Mazda Repairer.
