qSpare Tire
Your Mazda has a temporary spare tire.
The temporary spare tire is lighter and
smaller than a conventional tire, and is
designed only for emergency use and
should be used only for VERY short
periods. Temporary spare tires should
NEVER be used for long drives or
extended periods.
WARNING
Do not install the temporary spare tire
on the front wheels (driving wheels):
Driving with the temporary spare tire
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 tire to the front wheel and
install the temporary spare tire to the
rear.

CAUTION
ØWhen using the temporary spare
tire, driving stability may decrease
compared to when using only the
conventional tire.
Drive carefully.
ØTo avoid damage to the temporary
spare tire or to the vehicle, observe
the following precautions:
ØDo not exceed 80 km/h (50
mph).
ØAvoid driving over obstacles.
Also, do not drive through an
automatic car wash. This tire's
diameter is smaller than a
conventional tire's, so the
ground clearance is reduced
about 25 mm (1 in).
ØDo not use a tire chain on this
tire because it will not fit
properly.
ØDo not use your temporary
spare tire on any other vehicle;
it has been designed only for
your Mazda.
ØUse only one temporary spare
tire on your vehicle at the same
time.
Ø(With limited slip differential)
When using the temporary spare
tire on the front axle, replace it
with a standard tire as soon as
possible. The size difference
between the spare and the
standard tire will cause the limited
slip differential to malfunction.
NOTE
(With Tire Pressure Monitoring System)
A tire pressure sensor is not installed to the
temporary spare tire. The warning light will
flash continuously while the temporary spare
tire is being used (page 5-31).
To remove the spare tire
1. Remove the trunk board and spare tire
cover.

2. Turn the tire hold-down bolt
counterclockwise with the lug wrench.

If you are unsure of how tight the nuts
should be, have them inspected at an
Authorized Mazda Dealer.
Nut tightening torque
N·m (kgf·m, ft·lbf) 88―118 (9―12, 65―87)
WARNING
Always securely and correctly tighten
the lug nuts:
Improperly or loosely tightened lug
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 lug 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.
5. Remove the center cap by tapping it
with the lug wrench.
6. Store the damaged tire, using the wing
bolt to hold it in place.

Wing bolt
NOTE
Always use the wing bolt to secure the
damaged tire. Store the tire hold-down bolt
used to tighten down the spare tire in the same
place as where the wing bolt had been stored.
7. Remove the tire blocks and store the
tools, jack, and damaged tire.
8. Check the inflation pressure. Refer to
Tires on page 10-7.
9. Have the flat tire repaired or replaced
as soon as possible.
WARNING
Do not drive with any tires that have
incorrect air pressure:
Driving on tires with incorrect air
pressure is dangerous. Tires with
incorrect pressure could affect
handling and result in an accident.
When you check the regular tires' air
pressure, check the spare tire, too.
NOTE
(With Tire Pressure Monitoring System)
A tire pressure sensor is not installed to the
temporary spare tire. The warning light will
flash continuously while the temporary spare
tire is being used (page 5-31).
NOTE
To prevent the jack and tool from rattling, store
them properly.

WARNING
Always tow a AWD vehicle with all four
wheels off the ground:
Towing a AWD vehicle with either the
front or rear wheels on the ground is
dangerous as the drive train could be
damaged, or the vehicle could trail
away from the tow truck and cause
an accident. If the drive train has
been damaged, transport the vehicle
on a flat bed truck.
Tiedown Hooks
CAUTION
Do not use the front and rear
tiedown eyelets for towing the
vehicle.
They have been designed only for
securing the vehicle to a transport
vessel during shipping.
Using the eyelets for any other
purpose could result in the vehicle
being damaged.

Engine Coolant
qInspecting Coolant Level
WARNING
Do not use a match or live flame in the
engine compartment. DO NOT ADD
COOLANT WHEN THE ENGINE IS HOT:
A hot engine is dangerous. If the
engine has been running, parts of the
engine compartment can become
very hot. You could be burned.
Carefully inspect the engine coolant
in the coolant reservoir, but do not
open it.
Switch the ignition to off and
make sure the fan is not running before
attempting to work near the cooling
fan:
Working near the cooling fan when it
is running is dangerous. The fan
could continue running indefinitely
even if the engine has stopped and
the engine compartment temperature
is high. You could be hit by the fan
and seriously injured.
Do not remove either cooling
system cap when the engine and
radiator are hot:
When the engine and radiator are
hot, scalding coolant and steam may
shoot out under pressure and cause
serious injury.
NOTE
Changing the coolant should be done by an
Authorized Mazda Dealer.
Inspect the antifreeze protection and
coolant level in the coolant reservoir at
least once a year―at the beginning of the
winter season―and before traveling
where temperatures may drop below
freezing.
Inspect the condition and connections of
all cooling system and heater hoses.
Replace any that are swollen or
deteriorated.
The coolant should be at full in the
radiator and between the FULL and LOW
marks on the coolant reservoir when the
engine is cool.
If it is at or near LOW, add enough
coolant to the coolant reservoir to provide
freezing and corrosion protection and to
bring the level to FULL.
Securely tighten the coolant reservoir tank
cap after adding coolant.

NOTE
Remove the battery cover before performing
battery maintenance.
qBattery Maintenance
To get the best service from a battery:lKeep it securely mounted.lKeep the top clean and dry.lKeep terminals and connections clean,
tight, and coated with petroleum jelly
or terminal grease.
lRinse off spilled electrolyte
immediately with a solution of water
and baking soda.
lIf the vehicle will not be used for an
extended time, disconnect the battery
cables.
Tires
For reasons of proper performance, safety,
and better fuel economy, always maintain
recommended tire inflation pressures and
stay within the recommended load limits
and weight distribution.
WARNING
Using Different Tire Types:
Driving your vehicle with different
types of tires is dangerous. It could
cause poor handling and poor
braking; leading to loss of control.
Except for the limited use of the
temporary spare tire, use only the
same type tires (radial, bias-belted,
bias-type) on all four wheels.
Using Wrong-Sized Tires:
Using any other tire size than what is
specified for your Mazda (page 10-7)
is dangerous. It could seriously affect
ride, handling, ground clearance, tire
clearance, and speedometer
calibration. This could cause you to
have an accident. Use only tires that
are the correct size specified for your
Mazda.
