11. Insert the air compressor plug into theaccessory socket inside the vehicle and
switch the ignition to ACC.
Refer to Accessory Sockets on page
5-93.
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/cm
2, 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/ c m
2, 3 bar, 43.5 psi):
Using the air compressor at an inflation
pressure above 300 kPa (3.1 kgf/cm
2, 3
bar, 43.5 psi) continuously is
dangerous. If the air compressor
overheats, hot air will be exhausted and
you could get burned.
NOTE
Check the tire inflation pressure
label driver's door frame for the
correct tire inflation pressure.
Do not operate the air compressor
for a continuous 10 minutes or
longer because using it for long
periods could cause a malfunction.

4. Turn the lug wrench counterclockwiseand lower the vehicle.
5. 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.
6. Remove the tire blocks and store the tools and jack.
7. Check the inflation pressure. Refer to Tires on page 9-8.
WA R N I N G
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
To prevent the jack and tool from rattling,
store them properly.

Route the jumper cables away from parts that will be moving:
Connecting a jumper cable near or to moving parts (cooling fans, belts) is dangerous. The
cable 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 p ossible to your vehicle's
battery.
2. Make sure that the power such as for the headlights and air c onditioner is turned off.
3. Remove the battery cover.
4. Turn off the booster vehicle's engine and connect the jumper cables in the following
order.
Make sure that the jumper cables are securely connected so that they do not disconnect
due to engine vibrations.
