Key Battery Replacement
▼Key Battery Replacement
If the buttons on the transmitter are
inoperable and the operation indicator
light does not
flash, the battery may be
dead.
Replace with a new battery before the
transmitter becomes unusable.
CAUTION
¾Make sure the battery is installed
correctly. Battery leakage could occur
if it is not installed correctly.
¾When replacing the battery, be
careful not to touch any of the
internal circuitry and electrical
terminals, bend the electrical
terminals, or get dirt in the
transmitter as the transmitter could
be damaged.
¾There is the danger of explosion if
the battery is not correctly replaced.
¾Dispose of used batteries according
to the following instructions.
¾Insulate the plus and minus
terminals of the battery using
cellophane or equivalent tape.
¾Never disassemble.
¾Never throw the battery into fire or
water.
¾Never deform or crush.
¾Replace only with the same type
battery (CR2032 or equivalent).
The following conditions indicate that
the battery power is low:
xA message, “Low Key Fob Battery.
Replace Battery” is displayed on the
multi-information display when the
ignition is switched OFF.
xThe system does not operate and the
operation indicator light on the
transmitter does not flash when the
buttons are pressed.
xThe system's operational range is
reduced.
Incorrect battery replacement
operation may damage the key.
Replacing the battery at an expert
repairer (we recommend an
Authorised Mazda Repairer) is
recommended. If replacing the battery
by yourself, follow the instruction.

Ty re s
▼Ty re s
For reasons of proper performance,
safety, and better fuel economy, always
maintain recommended tyre
inflation
pressures and stay within the
recommended load limits and weight
distribution.
WARNING
Using
Different Ty re Ty p e s :
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
specified for the vehicle (page 9-10)
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 specified for the
vehicle.
▼Tyre Inflation Pressure
WARNING
Always inflate the tyres to the correct
pressure:
Overinflation or underinflation of tyres
is dangerous. Adverse handling or
unexpected tyre failure could result in
a serious accident.
Refer to Tyres on page 9-10.
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 when
the tyres are cold. Maintain
recommended pressures for the best
ride, handling, and minimum tyre
wear.
Refer to the specification charts (page
9-10).
NOTE
xAlways check tyre pressure when
tyres are cold.
xWarm tyres normally exceed
recommended pressures. Do not
release air from warm tyres to adjust
the pressure.
xUnderinflation 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.
xOverinflation 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
inflating, have it inspected.

▼Ty re Ro ta t i o n
WARNING
Rotate tyres periodically:
Irregular tyre wear is dangerous. To
equalize tread wear for maintaining
good performance in handling and
braking, rotate the tyres periodically or
sooner if irregular wear develops.
Please refer to Scheduled maintenance
for your tyre rotation interval.
During rotation, inspect them for
correct balance.
NOTE
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.

1. Forward
Do not include (TEMPORARY USE
ONLY) spare tyre in rotation.

Also, inspect them for uneven wear
and damage. Abnormal wear is usually
caused by one or a combination of the
following:

xIncorrect tyre pressurexImproper wheel alignment
xOut-of-balance wheelxSevere braking

After rotation, inflate all tyre pressures
to specification (page 9-10) and
inspect the wheel nuts for tightness.
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.
Maintenance and Care
Owner Maintenance
6-42

Replace the tyre when this happens.
1. New tread
2. Worn tread
3. Tread wear indicator
You should replace the tyre before the
band crosses the entire tread.
▼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:
¾Ty re
fit
¾Wheel and bearing life
¾Ground clearance
¾Snow-chain clearance
¾Speedometer calibration
¾Headlight aim
¾Bumper height
¾Tyre Pressure Monitoring System
*
NOTE
xWhen replacing a wheel, make sure
the new one is the same as the
original factory wheel in diameter,
rim width, and offset (inset/outset).
xFor details, contact an expert repairer
(we recommend an Authorised
Mazda Repairer).

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
flat spots.

Fuses
▼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,
first 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.
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.
