Bluetooth®
NOTE
  When the OS of the device is updated, the pairing information may be deleted. If this
happens, reprogramme the pairing information to the Bluetooth ® unit.   If you pair your phone which has already been paired to your vehicle more than once
in the past, you need to delete “Mazda” on your mobile device. Then, execute the
Bluetooth
® search on your mobile device once again, and pair to a newly detected
“Mazda”.
  Before you pair your device, make sure that Bluetooth ® is “ON”, both on your phone
and on the vehicle.
Voice recognition related problems
Symptom Cause Solution method
Poor voice recognition
Excessive, slow speech. Excessive, forceful speech
(shouting).
Speaking before the beep sound
has ended.
Loud noise (speaking or noise from
outside/inside vehicle).
Airfl ow from A/C is blowing
against the microphone.
Speaking in off-standard
expressions (dialect). Regarding the causes indicated
on the left, be careful with how
you speak. In addition, when
numbers are spoken in a sequence,
recognition ability will improve
if no stop is placed between the
numbers. False recognition of numbers
Poor voice recognition There is a malfunction in the
microphone. A poor connection or malfunction
with the microphone may have
occurred. Consult an expert repairer,
we recommend an Authorised
Mazda Repairer.
Phone-related voice recognition is
disabled There is a problem with the
connection between the Bluetooth
®
unit and the device. If there is any malfunction after
checking the pairing situation, check
for device pairing or connection
problems.
Names in the phonebook are not
easily recognised The Bluetooth
® system is under a
condition in which recognition is
diffi cult. By carrying out the following
measures, the rate of recognition
will improve. Clear memory from the phonebook
which is not used very often.
Avoid shortened names, use full
names. (Recognition improves the
longer the name is. By not using
names such as “Mum”, “Dad”,
recognition will improve.)
When operating the audio, a song
name is not recognised Song names cannot be recognised
by voice. —

SKYACTIV-D 2.2
If it is at or near L, add enough coolant to
the coolant reservoir to provide freezing
and corrosion protection and to bring the
level to F.
Securely tighten the coolant reservoir tank
cap after adding coolant.
CAUTION
  Radiator coolant will damage paint.  Rinse it off quickly if spilled.


 Use only soft (demineralised) water
in the coolant mixture. Water that
contains minerals will cut down on
the coolant's effectiveness.
  Do not add only water. Always add a
proper coolant mixture.
  The engine has aluminium parts and
must be protected by an ethylene-
glycol-based coolant to prevent
corrosion and freezing.
  DO NOT USE coolants Containing
Alcohol, methanol, Borate or
Silicate.
 These coolants could damage the
cooling system.
CAUTION
  DO NOT MIX alcohol or methanol
with the coolant. This could damage
the cooling system.
  Do not use a solution that contains
more than 60% antifreeze.
 This would reduce effectiveness.
 
 If the “FL22” mark is shown on or
near the cooling system cap, use
of FL-22 is recommended when
replacing engine coolant. Using
engine coolant other than FL-22 may
cause serious damage to the engine
and cooling system.
If the coolant reservoir is empty or new
coolant is required frequently, consult
an expert repairer, we recommend an
Authorised Mazda Repairer.

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.

5. Insert a new fuse of the same amperage
rating, and make sure it fi ts tightly. If
it does not fi t tightly, have an expert
install it. We recommend an Authorised
Mazda Repairer.
If you have no spare fuses, borrow one
of the same rating from a circuit not
essential to vehicle operation, such as
the AUDIO or OUTLET circuit.
CAUTION
Always replace a fuse with a genuine
Mazda fuse or equivalent of the same
rating. Otherwise you may damage the
electric system.
6. Reinstall the cover and make sure that
it is securely installed.
Replacing the fuses under the bonnet
