¾(SKYACTIV-D 2.2)
SKYACTIV-D 2.2 uses specified oil. Please confirm the specification in owner's manual. If
engine oil other than the
specified 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, SKYACTIV-G 2.5, and SKYACTIV-G 2.5T)
xIt 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.
(SKYACTIV-D 2.2)
xWhenever 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.
xInspect 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 refill so that the engine oil level
is within the range between MIN and MAX as shown in the figure.

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 expert repairer, we recommend an
Authorised Mazda Repairer.

¾Radiator coolant will damage paint.
Rinse it off quickly if spilled.
¾If 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 brake/clutch fluid level is low, have
the brakes inspected:
A low brake/clutch
fluid 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.
