Maintenance and Care
Appearance Care
Cleaning the Floor Mats
Rubber floor mats should be cleaned with
mild soap and water only.
WARNING
Do not use rubber cleaners, such as tire
cleaner or tire shine, when cleaning
rubber floor mats:
Cleaning the rubber floor mats with
rubber cleaning products makes the
floor mats slippery.
This may cause an accident when
depressing the accelerator, brake, or
clutch (Manual transmission) pedal or
when getting in or out of the vehicle.
After removing the floor mats for cleaning,
always reinstall them securely (page
3-44).

6. Shake the sealant bottle to mix the
contents. Then extend the injection
hose.
Injection hose
CAUTION
Do not shake the bottle excessively.
Otherwise, the sealant could spray out
of the injection hose, and if the sealant
contacts clothing or other objects, you
may not be able to remove it.
NOTE
The sealant hardens easily and injecting
it will be difficult under cold weather
conditions (0 °C (32 °F) or below). Warm
the sealant inside the vehicle to facilitate
injection.
7. Pull out the air compressor hose and
the air compressor plug from the air
compressor.
Compressor hose
8. Install the air compressor hose which
was pulled out of the air compressor to
the injection valve of the bottle.

CAUTION
Make sure that the air compressor
switch is off before inserting the air
compressor hose to the injection valve
of the bottle. If the air compressor hose
is not installed to the injection valve
of the bottle securely, the sealant may
leak.
9. Remove the valve cap from the valve
of the flat tire, install the injection hose
to the tire valve, turn the sleeve to the

Refer to Accessory Sockets on page
5-133.
Compressor
Compressor plug
CAUTION
When inserting the air compressor
plug into or removing it from the
accessory socket, make sure that the
air compressor switch is off. When
turning the air compressor on/off, use
the air compressor switch.
12. The sealant is injected into the tire
when the air compressor is switched
on. After the sealant is injected
completely, wait until the tire inflation
pressure increases to the specified tire
inflation pressure.
NOTE
The inflation pressure may increase to
about 300 kPa (3.1 kgf/cm2, 3 bar, 43.5
psi) temporarily to inject the sealant
through the valve. Normally, the inflation
pressure decreases gradually and it
reaches the actual inflation pressure after
about 30 seconds.
WARNING
Never use the air compressor above 300
kPa (3.1 kgf/cm2, 3 bar, 43.5 psi):
Using the air compressor at an
inflation pressure above 300 kPa (3.1
kgf/cm2, 3 bar, 43.5 psi) continuously
is dangerous. If the air compressor
overheats, hot air will be exhausted
and you could get burned.
CAUTION
If the air compressor operates slowly
or becomes hot, this indicates
overheating. Turn the air compressor
off immediately and cancel the
procedure. In this case, leave the air
compressor turned off for about 30
minutes or longer and wait until the
temperature decreases.

4. Turn the lug wrench counterclockwise
and lower the vehicle. Use the lug
wrench to tighten the nuts in the order
shown.

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)108—147 (12—14, 80—108)
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 tire blocks and store the
tools and jack.
6. Check the inflation pressure. Refer to
Tires on page 9-8.
NOTE
(With tire pressure monitoring system)
Do not press the tire pressure monitoring
system set switch after installing the spare
tire. The switch is only to be pressed after
installing the repaired flat tire or installing
a replacement tire (page 4-16).

the negative terminal of the booster
battery (3). Connect the other end to the ground
point indicated in the illustration

5. Start the engine of the booster vehicle
and run it a few minutes. Then start the
engine of the other vehicle.
6. When finished, carefully disconnect the
cables in the reverse order described in
the illustration.
