Battery Maintenance
To get the best service from a battery:




 Keep it securely mounted.



 Keep the top clean and dry.



 Keep terminals and connections clean,
tight, and coated with petroleum jelly or
terminal grease.
 


 Rinse off spilled electrolyte immediately
with a solution of water and baking
soda.
 


 If the vehicle will not be used for an
extended time, disconnect the battery
leads and charge the battery every six
weeks.
Inspecting Electrolyte Level *
A low level of electrolyte fl uid will cause
the battery to discharge quickly.
Upper level
Lower level
Inspect the electrolyte level at least once
a week. If it is low, remove the caps and
add enough distilled water to bring the
level between the upper and lower level
(illustration).
Do not overfi ll.
Examine the specifi c gravity of the
electrolyte with a hydrometer, especially
during cold weather. If it is low, recharge
the battery.
Battery Recharging
NOTE
  Before performing maintenance or
recharging the battery, turn off all
accessories and stop the engine.
  To disconnect the battery, remove the
negative lead fi rst. Install it last when
connecting the battery.
  Be sure to remove the caps before
recharging the battery.
 (With i-stop system) Do not quick-charge the battery.




 If the battery quickly discharges
because, for example, the lights were
left on too long with the engine off,
slow-charge it as required by battery
size and charger capacity.
 


 If the battery gradually discharges
because of high electric load while the
vehicle is being used, recharge it as
required by battery size and charger
capacity.
Battery Replacement
Contact an Authorised Mazda Dealer for a
battery replacement purchase.

Ty r e s
For reasons of proper performance, safety,
and better fuel economy, always maintain
recommended tyre infl ation pressures and
stay within the recommended load limits
and weight distribution.
WARNING
Using Different Tyre Types:
Driving your vehicle with different
types of tyres is dangerous. It could
cause poor handling and poor braking;
leading to loss of control.
Except for the limited use of the
temporary spare tyre, use only the same
type tyres (radial, bias-belted, bias-type)
on all four wheels.
Using Wrong-Sized Tyres:
Using any other tyre size than what is
specifi ed for the vehicle (page 9-13 )
is dangerous. It could seriously affect
ride, handling, ground clearance,
tyre clearance, and speedometer
calibration. This could cause you to
have an accident. Use only tyres that
are the correct size specifi ed for the
vehicle.

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.

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.
