Cooling system cap Coolant reservoir
Cooling fan

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 or FULL.
Securely tighten the coolant reservoir tank
cap after adding coolant.
CAUTION
  Radiator coolant will damage paint.  Rinse it off quickly if spilled. 

 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 À 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 over¿ ll.
Examine the speci¿ 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 ¿ 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 Repairer for
a battery replacement purchase.

Fuses
Your vehicle's electrical system is
protected by fuses.

If any lights, accessories, or controls do
not work, inspect the appropriate circuit
protector. If a fuse has blown, the inside
element will be melted.

If the same fuse blows again, avoid using
that system and consult an expert repairer,
we recommend an Authorised Mazda
Repairer as soon as possible.
Fuse Replacement
Replacing the fuses on the vehicle's left
side
If the electrical system does not work, ¿ rst
inspect the fuses on the vehicle's left side.


1. Make sure the ignition is switched off,
and other switches are off.
2. Open the fuse panel cover.

3. Pull the fuse straight out with the
fuse puller provided on the fuse block
located in the engine compartment.


4. Inspect the fuse and replace it if it is
blown.

NormalBlown

5. Insert a new fuse of the same amperage
rating, and make sure it ¿ ts tightly. If
it does not ¿ 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
If the headlights or other electrical
components do not work and the fuses
in the cabin are normal, inspect the fuse
block under the bonnet. If a fuse is blown,
it must be replaced. Follow these steps:


1. Make sure the ignition is switched off,
and other switches are off.
2. Remove the fuse block cover.


3. If any fuse but the MAIN fuse is
blown, replace it with a new one of the
same amperage rating .

Normal
Blown

WARNING
Do not replace the main fuse by
yourself. Have an Authorised Mazda
Repairer perform the replacement:
Replacing the fuse by yourself is
dangerous because the MAIN fuse
is a high current fuse. Incorrect
replacement could cause an electrical
shock or a short circuit resulting in a
¿ re.
4. Reinstall the cover and make sure that
it is securely installed.

NOTE
If the jack is not completely secured, it
could rattle while driving. Make sure the
jack screw is suf¿ ciently tightened.
4. Insert the cover tabs and install the
cover.
NOTE
Verify that the cover is securely
installed.
M a i n t e n a n c e
 




 Always keep the jack clean.



 Make sure the moving parts are kept
free from dirt or rust.
 


 Make sure the screw thread is
adequately lubricated.

Spare Tyre *
Your Mazda has a temporary spare tyre.
The temporary spare tyre is lighter and
smaller than a conventional tyre, and is
designed only for emergency use and
should be used only for VERY short
periods. Temporary spare tyres should
NEVER be used for long drives or
extended periods.
WARNING
Do not install the temporary spare tyre
on the front wheels (driving wheels):
Driving with the temporary spare tyre
on one of the front driving wheels is
dangerous. Handling will be affected.
You could lose control of the vehicle,
especially on ice or snow bound roads,
and have an accident. Move a regular
tyre to the front wheel and install the
temporary spare tyre to the rear.

4. For vehicles equipped with a sub-
woofer, uncouple the connector.

NOTE
Extra strength may be required to
uncouple the connector. Be sure to
squeeze the tab ¿ rmly.
5. For vehicles equipped with a sub-
woofer, loosen the hold-down bolt and
remove the woofer and spare tyre.



For vehicles not equipped with a sub-
woofer, turn the spare tyre hold-down
bolt anticlockwise and remove the
spare tyre.

To secure the spare tyre
Store the spare tyre in the reverse order
of removal. After storing, verify that the
spare tyre is stored securely.

4. Turn the wheel brace anticlockwise and
lower the vehicle.
5. 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
N·m (kgf·m, ft·lbf) 108—147 (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.

Be sure to reinstall the same nuts you
removed or replace them with metric
nuts of the same con¿ 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.
6. Remove the tyre blocks and store the
tools and jack.
7. Store the damaged tyre in the luggage
compartment.
8. Check the inÀ ation pressure. Refer to
Tyres on page 9-9 .
9. Have the À 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 À at tyre or installing a
replacement tyre (page 4-36 ).

If Trouble Arises
Battery Runs Out
1. Remove the battery cover.



2. Make sure the booster battery is
12 V and that its negative terminal is
grounded.
3. If the booster battery is in another
vehicle, do not allow both vehicles
to touch. Turn off the engine of the
vehicle with the booster battery and
all unnecessary electrical loads in both
vehicles.
4. Connect the jumper leads in the exact
sequence as in the illustration.
 

 
 Connect one end of a lead to the
positive terminal on the discharged
battery (1).
 

 
 Attach the other end to the positive
terminal on the booster battery (2).
 

 
 Connect one end of the other lead to
the negative terminal of the booster
battery (3).
 

 
 Connect the other end to the ground
point indicated in the illustration
away from the discharged battery (4).

5. Start the engine of the booster vehicle
and run it a few minutes. Then start the
engine of the other vehicle.
6. When ¿ nished, carefully disconnect the
leads in the reverse order described in
the illustration. 7. If the battery cover has been removed,
install it in the reverse order of
removal.

NOTE
Verify that the covers are securely
installed.
