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.

When replacing a wheel, make sure the
new one is the same as the original factory
wheel in diameter, rim width, and offset
(inset/outset).
Proper tyre balancing provides the best
riding comfort and helps reduce tread
wear. Out-of-balance tyres can cause
vibration and uneven wear, such as
cupping and fl at spots.

CAUTION
When inserting the air compressor
plug into or removing it from the
accessory socket, make sure that the air
compressor switch is OFF. When turning
the air compressor ON/OFF, use the air
compressor switch.
12. The sealant is injected into the tyre
when the air compressor is switched
ON. After the sealant is injected
completely, wait until the tyre infl ation
pressure increases to the specifi ed tyre
infl ation pressure.
NOTE
The infl ation pressure may increase
to about 300 kPa (3.1 kgf/cm 2 , 3 bar,
43.5 psi) temporarily to inject the
sealant through the valve. Normally, the
infl ation pressure decreases gradually
and it reaches the actual infl ation
pressure after about 30 seconds.

WARNING
Never use the air compressor above 300
kPa (3.1 kgf/cm 2 , 3 bar, 43.5 psi):
Using the air compressor at an
infl ation pressure above 300 kPa (3.1
kgf/cm
2 , 3 bar, 43.5 psi) continuously
is dangerous. If the air compressor
overheats, hot air will be exhausted and
you could get burned.
CAUTION
If the air compressor operates slowly or
becomes hot, this indicates overheating.
Turn the air compressor OFF
immediately and cancel the procedure.
In this case, leave the air compressor
turned OFF for about 30 minutes or
longer and wait until the temperature
decreases.
NOTE
  Check the tyre infl ation pressure
label (driver's door frame) for the
correct tyre infl ation pressure.

 Do not operate the air compressor for
a continuous 10 minutes or longer
because using it for long periods
could cause a malfunction.
  If the tyre infl ation pressure does
not increase, repair of the tyre is not
possible. If the tyre does not reach
the specifi ed tyre infl ation pressure
within 10 minutes, it may have
received extensive damage. In this
case, the repair using the emergency
fl at tyre repair kit was not successful.
Contact an expert repairer, we
recommend an Authorised Mazda
Repairer.

Adhering the speed restriction sticker
to the padded area on the steering
wheel is dangerous because the air
bag may not operate (deploy) normally
resulting in serious injury. In addition,
do not adhere the sticker to areas where
warning lights or the speedometer
cannot be viewed.
14. When the tyre infl ates to the specifi ed
tyre infl ation pressure, turn the air
compressor switch OFF, turn the sleeve
of the injection hose to the left, and pull
it out of the tyre valve. Turn the sleeve
of the injection hose to the left, and pull
it out of the tyre valve.
15. Remove the compressor hose from the
injection valve of the bottle. After that,
install the injection hose to the injection
valve of the bottle to prevent leakage of
any remaining sealant.
CAUTION
The remaining sealant in the hose may
spray out when the hose is removed.
Remove the hose carefully because you
may not be able to remove the sealant
contacting clothing or other objects.
16. Install the tyre valve cap.
17. Put the puncture tyre repair kit into the
boot/luggage compartment.
18. Start driving immediately to spread the
sealant in the tyre.
CAUTION
Carefully drive the vehicle at a speed of
80 km/h (50 mph) or less. If the vehicle
is driven at a speed of 80 km/h (50 mph)
or more, the vehicle may vibrate.
NOTE
(With Tyre Pressure Monitoring
System)
If the tyre is not properly infl ated, the
tyre pressure monitoring system warning
light will illuminate (page 4-40 ).
19. After driving the vehicle for about 10
minutes or 5 km (3 miles), connect
the air compressor to the tyre using
Step 9 of the procedure, and check the
tyre infl ation pressure using the tyre
pressure gauge on the air compressor. If
the tyre infl ation pressure is lower than
the specifi ed tyre infl ation pressure,
turn the air compressor ON and wait
until it reaches the specifi ed tyre
infl ation pressure.

repeatedly, stop driving:
Contact an expert repairer, we
recommend an Authorised Mazda
Repairer.
CAUTION
Before checking the tyre infl ation
pressure using the tyre pressure gauge,
turn the air compressor switch OFF.
20. The emergency fl at tyre repair is
completed successfully if the tyre
infl ation pressure does not decrease.
Carefully drive the vehicle to the
nearest expert repairer, we recommend
an Authorised Mazda Repairer
immediately and have the fl at tyre
replaced. Replacement with a new tyre
is recommended. If the tyre is to be
repaired or reused, consult an expert
repairer, we recommend an Authorised
Mazda Repairer.
NOTE
  If an emergency fl at tyre repair has
been performed using the puncture
tyre repair kit, Mazda recommends
that the tyre be replaced with a new
one as soon as possible. If the tyre is
to be repaired or reused, consult an
expert repairer, we recommend an
Authorised Mazda Repairer.
  The wheel can be reused if the
sealant adhering to it is removed.
However, replace the valve with a
new one.
Inspecting the Emergency Flat
Tyre Repair Kit
Inspect the emergency fl at tyre repair kit at
regular intervals.
 


 Check the tyre sealant period of
effective use.
 


 Check the operation of the tyre
compressor.
NOTE
The tyre sealant has a period of effective

If Trouble Arises
Flat Tyre
WARNING
Always securely and correctly tighten
the wheel nuts:
Improperly or loosely tightened wheel
nuts are dangerous. The wheel could
wobble or come off. This could result
in loss of vehicle control and cause a
serious accident.
Be sure to reinstall the same nuts you
removed or replace them with metric
nuts of the same confi guration:
Because the wheel studs and wheel
nuts on your Mazda have metric
threads, using a non-metric nut is
dangerous. On a metric stud, it would
not secure the wheel and would
damage the stud, which could cause the
wheel to slip off and cause an accident.
5. Remove the tyre blocks and store the
tools and jack.
6. Store the damaged tyre in the luggage
compartment.
7. Check the infl ation pressure. Refer to
Tyres on page 9-13 .
8. Have the fl at tyre repaired or replaced
as soon as possible.
NOTE
Do not press the tyre pressure
monitoring system set switch after
installing the spare tyre. The switch
is only to be pressed after installing
the repaired fl at tyre or installing a
replacement tyre (page 4-40 ).
WARNING
Do not drive with any tyres that have
incorrect air pressure:
Driving on tyres with incorrect air
pressure is dangerous. Tyres with
incorrect pressure could affect
handling and result in an accident.
When you check the regular tyres' air
pressure, check the spare tyre, too.
NOTE
To prevent the jack and tool from
rattling, store them properly.
