Always keep batteries out of
the reach of children:
Allowing children to play near batteries
is dangerous. Battery fluid could cause
serious injuries if it gets in the eyes or
on the skin.
Keep flames and sparks away
from open battery cells and do not
allow metal tools to contact the
positive (+) or negative (-) terminal of
the battery when working near a
battery. Do not allow the positive (+)
terminal to contact the vehicle body:
Flames and sparks near open battery
cells are dangerous. Hydrogen gas,
produced during normal battery
operation, could ignite and cause the
battery to explode. An exploding
battery can cause serious burns and
injuries. Keep all flames including
cigarettes and sparks away from open
battery cells.
Keep all flames and sparks
away from open battery cells because
hydrogen gas is produced from open
battery cells while charging the
battery or adding battery
fluid:

block located in the engine
compartment.
4. Inspect the fuse and replace it if it is
blown.
1. Normal
2. Blown

5. Insert a new fuse of the same
amperage rating , and make sure it
fits tightly. If it does not
fit tightly,
have an expert install it. Consult an
expert repairer (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
accessory socket 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.
1. Normal
2. Blown

WARNING
Do not replace the main fuse by
yourself. Have an expert repairer
(we recommend 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 fire.
4. Reinstall the cover and make sure
that it is securely installed.

Parking in an Emergency
▼Parking in an Emergency
The hazard warning lights should
always be used when you stop on or
near a roadway in an emergency.

The hazard warning lights warn other
drivers that your vehicle is a traffic
hazard and that they must take
extreme caution when near it.

Depress the hazard warning flasher
and all the direction indicators will
flash. The hazard warning indicator
lights in the instrument cluster flash
simultaneously.
NOTE
xThe direction indicators do not work
when the hazard warning lights are
on.
xCheck local regulations about the
use of hazard warning lights while
the vehicle is being towed to verify
that it is not in violation of the law.

▼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.
CAUTION
¾When using the temporary spare
tyre, driving stability may decrease
compared to when using only the
conventional tyre. Drive carefully.
¾To avoid damage to the temporary
spare tyre or to the vehicle, observe
the following precautions:
If Trouble Arises
Flat Tyre
*Some models.7-25

¾Do not exceed 80 km/h (50 mph).
¾Avoid driving over obstacles. Also,
do not drive through an automatic
car wash. This tyre's diameter is
smaller than a conventional tyre,
so the ground clearance is
reduced.
¾Do not use a tyre chain on this tyre
because it will not fit properly.
¾Do not use your temporary spare
tyre on any other vehicle, it has
been designed only for your
Mazda.
¾Use only one temporary spare tyre
on your vehicle at the same time.
To remove the spare tyre
1. Remove the luggage mat.

2.(Vehicles with sub-woofer)
Uncouple the sub-woofer
connector.

1. Sub-woofer

NOTE
Extra strength may be required to
uncouple the connector. Be sure to
squeeze the tab firmly.
3.(Vehicles with sub-woofer)
Turn the spare tyre hold-down bolt
anticlockwise and remove the
sub-woofer and the spare tyre.

(Vehicles without sub-woofer)
Turn the spare tyre hold-down bolt
anticlockwise and remove the spare
tyre.

1. Spare tyre hold-down bolt

NOTE
If the spare tyre hold-down bolt
cannot be loosened, hold the edge
of the tyre and turn it anticlockwise
until the spare tyre hold-down bolt
rotates.
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.

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)108Š147 (12Š14,
80Š108)
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
configuration:
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 inflation pressure. Refer
to Tyres on page 9-10.
9. Have the flat tyre repaired or
replaced as soon as possible.
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.

Route the jumper leads away from parts that will be moving:
Connecting a jumper lead near or to moving parts (cooling fans, belts) is dangerous.
The lead could get caught when the engine starts and cause serious injury.
CAUTION
Use only a 12 V booster system. You can damage a 12 V starter, ignition system, and
other electrical parts beyond repair with a 24 V power supply (two 12 V batteries in
series or a 24 V motor generator set).
1. Move the booster vehicle so that its battery is as close as possible to your
vehicle's battery.
2. Make sure that the power such as for the headlights and air conditioner is turned
off.
3. Remove the battery cover.
4. Turn off the booster vehicle's engine and connect the jumper leads in the
following order.
Make sure that the jumper leads are securely connected so that they do not
disconnect due to engine vibrations.
