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.

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.

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.

Key Battery Replacement
If the buttons on the transmitter are
inoperable and the operation indicator
light does not fl ash, the battery may be
dead.
Replace with a new battery before the
transmitter becomes unusable.
CAUTION
Make sure the battery is installed
correctly. Battery leakage could
occur if it is not installed correctly.
When replacing the battery, be
careful not to touch any of the
internal circuitry and electrical
terminals, bend the electrical
terminals, or get dirt in the
transmitter as the transmitter could
be damaged.
There is the danger of explosion if
the battery is not correctly replaced.
Dispose of used batteries according
to the following instructions.
Insulate the plus and minus
terminals of the battery using
cellophane or equivalent tape.
Never disassemble.
Never throw the battery into fi re or
water.
Never deform or crush.
Replace only with the same type
battery (CR2025 or equivalent).
The following conditions indicate that the
battery power is low:
The KEY indicator light (green) fl ashes
in the instrument cluster for about 30
seconds after the engine is turned off.
The system does not operate and
the operation indicator light on the
transmitter does not fl ash when the
buttons are pressed.
The system's operational range is
reduced.
Replacing the battery at an Authorised

Tyre Infl ation Pressure
WARNING
Always infl ate the tyres to the correct
pressure:
Overinfl ation or underinfl ation of tyres
is dangerous. Adverse handling or
unexpected tyre failure could result in
a serious accident.
Refer to Tyres on page 9-13 .
Use only a Mazda-genuine tyre valve
cap:
Use of a non-genuine part is dangerous
as the correct tyre air pressure cannot
be maintained if the tyre valve becomes
damaged. If the vehicle is driven under
this condition, the tyre air pressure
will decrease which could result in a
serious accident. Do not use any part
for the tyre valve cap that is not a
Mazda-genuine part.
Inspect all tyre pressures monthly
(including the spare
* ) when the tyres are
cold. Maintain recommended pressures for
the best ride, handling, and minimum tyre
wear.
Refer to the specifi cation charts (page
9-13 ).
After adjusting the tyre pressure,
initialization of the tyre pressure
monitoring system is necessary to make
the system operate normally.
Refer to Tyre Pressure Monitoring System
Initialization on page 4-164 .
NOTE
Always check tyre pressure when
tyres are cold.
Warm tyres normally exceed
recommended pressures. Do not
release air from warm tyres to adjust
the pressure.
Underinfl ation can cause reduced
fuel economy, uneven and
accelerated tyre wear, and poor
sealing of the tyre bead, which
will deform the wheel and cause
separation of tyre from rim.
Overinfl ation can produce a harsh
ride, uneven and accelerated tyre
wear, and a greater possibility of
damage from road hazards.
Keep your tyre pressure at the correct
levels. If one frequently needs
infl ating, have it inspected.
Tyre Rotation
WARNING
Rotate tyres periodically:
Irregular tyre wear is dangerous. To
equalize tread wear for maintaining
good performance in handling and
braking, rotate the tyres every 10,000
km (6,250 miles), or sooner if irregular
wear develops.
During rotation, inspect them for correct
balance.

Maintenance and Care
Owner Maintenance
NOTE
(Without temporary spare tyre)
Because your vehicle is not equipped
with a spare tyre, you cannot do a tyre
rotation safely with the jack that comes
with your vehicle. Have an expert
repairer, we recommend an Authorised
Mazda Repairer perform tyre rotation.
Do not include (TEMPORARY USE ONLY)
spare tyre in rotation.Forward
Also, inspect them for uneven wear and
damage. Abnormal wear is usually caused
by one or a combination of the following:
Incorrect tyre pressure
Improper wheel alignment
Out-of-balance wheel
Severe braking
After rotation, infl ate all tyre pressures to
specifi cation (page 9-13 ) and inspect the
wheel nuts for tightness.
After adjusting the tyre pressure,
initialization of the tyre pressure
monitoring system is necessary to make
the system operate normally.
Refer to Tyre Pressure Monitoring System
Initialization on page 4-164 .
CAUTION
Rotate unidirectional tyres and radial
tyres that have an asymmetrical tread
pattern or studs only from front to rear,
not from side to side. Tyre performance
will be reduced if rotated from side to
side.
Replacing a Tyre
WARNING
Always use tyres that are in good
condition:
Driving with worn tyres is dangerous.
Reduced braking, steering, and traction
could result in an accident.
Replace all four tyres at the same time:
Replacing just one tyre is dangerous.
It could cause poor handling and poor
braking resulting in loss of vehicle
control. Mazda strongly recommends
that you replace all four tyres at the
same time.

If a tyre wears evenly, a wear indicator
will appear as a solid band across the
tread.
Replace the tyre when this happens.
New treadTread wear indicator
Worn tread
You should replace the tyre before the
band crosses the entire tread.
After adjusting the tyre pressure,
initialization of the tyre pressure
monitoring system is necessary to make
the system operate normally.
Refer to Tyre Pressure Monitoring System
Initialization on page 4-164 .
Temporary Spare Tyre *
Inspect the temporary spare tyre at least
monthly to make sure it is properly
infl ated and stored.
NOTE
The temporary spare tyre condition
gradually deteriorates even if it has not
been used.
The temporary spare tyre is easier to
handle because of its construction which
is lighter and smaller than a conventional
tyre. This tyre should be used only for an
emergency and only for a short distance. Use the temporary spare tyre only until
the conventional tyre is repaired, which
should be as soon as possible.
Refer to Tyre on page 9-13 .
CAUTION
Do not use your temporary spare
tyre rim with a snow tyre or a
conventional tyre. Neither will
properly fi t and could damage both
tyre and rim.
The temporary spare tyre has a tread
life of less than 5,000 km (3,000
miles). The tread life may be shorter
depending on driving conditions.
The temporary spare tyre is for
limited use, however, if the tread
wear solid-band indicator appears,
replace the tyre with the same type of
temporary spare (page 6-48 ).
Replacing a Wheel
WARNING
Always use wheels of the correct size
on your vehicle:
Using a wrong-sized wheel is
dangerous. Braking and handling
could be affected, leading to loss of
control and an accident.

If Trouble Arises
Overheating
Overheating
If the High engine coolant temperature
warning light illuminates, the vehicle loses
power, or you hear a loud knocking or
pinging noise, the engine is probably too
hot.
WARNING
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.
Open the bonnet ONLY after steam is
no longer escaping from the engine:
Steam from an overheated engine is
dangerous. The escaping steam could
seriously burn you.
If the High engine coolant temperature
warning light illuminates:
1. Drive safely to the side of the road and
park off the right-of-way.
2. Put a vehicle with an automatic
transaxle in park (P), a manual
transaxle in neutral.
3. Apply the parking brake.
4. Turn off the air conditioner.
5. Check whether coolant or steam is
escaping from the engine compartment.
If steam is coming from the engine
compartment:
Do not go near the front of the vehicle.
Stop the engine.
Wait until the steam dissipates, then
open the bonnet and start the engine.
If neither coolant nor steam is
escaping:
Open the bonnet and idle the engine
until it cools.
CAUTION
If the cooling fan does not operate
while the engine is running, the engine
temperature will increase. Stop the
engine and call an expert repairer,
we recommend an Authorised Mazda
Repairer.
6. Make sure the cooling fan is operating,
then turn off the engine after the
temperature has decreased.
7. When cool, check the coolant level.
If it is low, look for coolant leaks from
the radiator and hoses.
