WARNING
Do not perform maintenance work if you lack suffi cient knowledge and experience
or the proper tools and equipment to do the work. Have maintenance work done by a
qualifi ed technician:
Performing maintenance work on a vehicle is dangerous if not done properly. You can
be seriously injured while performing some maintenance procedures.
If you must run the engine while working under the bonnet, make certain that you
remove all jewellery (especially rings, bracelets, watches, and necklaces) and all
neckties, scarves, and similar loose clothing before getting near the engine or cooling
fan which may turn on unexpectedly:
Working under the bonnet with the engine running is dangerous. It becomes even more
dangerous when you wear jewellery or loose clothing.
Either can become entangled in moving parts and result in injury.
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 leave items in the engine compartment:
After you have fi nished checking or doing servicing in the engine compartment, do not
forget and leave items such as tools or rags in the engine compartment.
Tools or other items left in the engine compartment could cause engine damage or a fi re
leading to an unexpected accident.

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.

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.

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.

Automatic Transaxle
Fluid (4-speed transaxle)
Inspecting Automatic Transaxle
Fluid Level
The automatic transaxle fl uid level should
be inspected regularly. Measure it as
described below.
The volume of fl uid changes with
temperature. Fluid must be checked while
idling the engine without driving at normal
operating temperature.
1. Park on a level surface and set the
parking brake fi rmly.
2. Start the engine and depress the brake
pedal.
3. Move the shift lever through all ranges
and set it at P.
WARNING
Make sure the brake pedal is applied
before shifting the shift lever:
Shifting the shift lever without
fi rst depressing the brake pedal is
dangerous. The vehicle could move
suddenly and cause an accident.
4. With the engine still idling, pull out the
dipstick, wipe it clean, and put it back.
5. Pull it out again.
The proper fl uid level is marked on the
dipstick as follows.
A
B Full
Full
Low
Low
Fluid hot scale A
When the vehicle has been driven and the
fl uid is at normal operating temperature,
about 65°C (150°F), the level must be
between Full and Low.
Fluid cold scale B
When the engine has not been running
and the outside temperature is about 20°C
(70°F), the level must be between Full and
Low.

CAUTION
  Use the cold scale only as a
reference.
  If outside temperature is lower
than about 20°C (70°F), start the
engine and inspect the fl uid level
after the engine reaches operating
temperature.
  If the vehicle has been driven for an
extended period at high speeds or in
city traffi c in hot weather, inspect the
level only after stopping the engine
and allowing the fl uid to cool for 30
minutes.
If the ATF level does not reach the
appropriate level, consult an expert
repairer, we recommend an Authorised
Mazda Repairer to have the vehicle
inspected.
NOTE
Inspect the fl uid on both sides of the
dipstick in a well lit area for an accurate
reading.

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.
