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 9-9 .
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
9-9 ).
(With tyre pressure monitoring system)
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 4-166 .
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 9-9 ) and inspect the
wheel nuts for tightness.
(With tyre pressure monitoring system)
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 4-166 .
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.

You should replace the tyre before the
band crosses the entire tread.
(With tyre pressure monitoring system)
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 4-166 .
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 9-9 .
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 6-45 ).

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.
CAUTION
A wrong-sized wheel may adversely
affect:
 
 Tyre fi t 
 Wheel and bearing life 
 Ground clearance 
 Snow-chain clearance 
 Speedometer calibration 
 Headlight aim 
 Bumper height 
 Tyre Pressure Monitoring System *
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.

Operating the compressor above 300
kPa (3.1 kgf/cm
2 , 3 bar, 43.5 psi) is
dangerous. When the infl ation pressure
rises above 300 kPa (3.1 kgf/cm
2 , 3 bar,
43.5 psi), heated air will be exhausted
from the back of the compressor and
you could be burned.

CAUTION
If the compressor operates slowly or
becomes hot, it indicates overheating.
Turn the compressor off immediately
and leave it turned off for 30 minutes or
longer.
NOTE
  Check the tyre infl ation pressure
label (driver's door frame) for the
correct tyre infl ation pressure.

 Do not use the compressor for longer
than 10 minutes because using the
compressor for long periods could
damage it.
  If the tyre does not infl ate, repair
of the tyre may not be possible. If
the tyre does not reach the correct
infl ation pressure within a 10-minute
period, it probably has received more
extensive damage.
 When this happens, the emergency
fl at tyre repair kit cannot be used
to repair the tyre. Contact an
expert repairer, we recommend an
Authorised Mazda Repairer.
  If the tyre has been over-infl ated,
loosen the screw cap on the
compressor and bleed some of the air
out.
18. When the tyre has been infl ated to
the proper infl ation pressure, turn the
compressor switch off and remove the
compressor hose from the tyre valve.
19. Install the tyre valve cap.
20. Put the emergency fl at tyre repair kit in
the luggage compartment and continue
driving.
CAUTION
  Drive carefully to an expert repairer,
we recommend an Authorised Mazda
Repairer and keep the vehicle speed
below 80 km/h (50 mph).
  If the vehicle is driven 80 km/h (50
mph) or higher, the vehicle might
begin to vibrate.
NOTE
(With tyre pressure monitoring
system)
If the tyre is not properly infl ated, the
tyre pressure monitoring system warning
light will illuminate.
21. After driving the vehicle for 10 minutes
or 5 km (3 miles), check the tyre
pressure with the tyre pressure gauge
equipped with the compressor. If the
tyre pressure has fallen below the
correct tyre pressure, infl ate the tyre to
the correct pressure again following the
steps from number 16.

CAUTION
  If the tyre infl ation pressure falls
below 130 kPa (1.3 kgf/cm 2 or bar,
18.9 psi), repair cannot be done with
the repair kit. Park the vehicle on
a level surface off the right-of-way
and contact an expert repairer, we
recommend an Authorised Mazda
Repairer.
  If the tyre infl ation pressure
continues to remain low after
repeating steps 15 to 21, park
the vehicle on a level surface off
the right-of-way and contact an
expert repairer, we recommend an
Authorised Mazda Repairer.
NOTE
When checking the tyre infl ation
pressure with the tyre pressure gauge
on the compressor unit, make sure the
compressor switch is turned off.
22. If the tyre infl ation pressure remains
stable, the tyre repair is complete.
Drive the vehicle with care to an expert
repairer, we recommend an Authorised
Mazda Repairer to have the tyre
replaced.
CAUTION
  A tyre that has been temporarily
repaired with the tyre sealant cannot
be reused. Mazda recommends
replacing the tyre with a new one.
  The wheel can be reused after any
sealant adhering to it is wiped off and
carefully inspected. However, replace
the tyre 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
use. Check the period of effective use
indicated on the bottle label and do not
use it if it has expired. Have the tyre
sealant replaced at an Authorised Mazda
Repairer before the period of effective
use has expired.

4. Turn the wheel brace anticlockwise and
lower the vehicle. Use the wheel brace
to tighten the nuts in the order shown.
If you are unsure of how tight the nuts
should be, have them inspected at an
expert repairer, we recommend an
Authorised Mazda Repairer.
Nut tightening torque

(12—14, 80—108)
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.
WARNING
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 9-9 .
8. Have the fl at tyre repaired or replaced
as soon as possible.
NOTE
(With tyre pressure monitoring
system)
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 4-36 ).
