qFlexible Floor Board (5 Door)í
The luggage compartment can be
separated vertically and/or horizontally,
using the trunk board and the trunk board
loops.
CAUTION
Make sure the trunk board is firmly
secured when it is fitted into the trunk
board loops. If it is not firmly secured,
it could unexpectedly disengage
causing damage to the trunk board
loops or the trunk board.
NOTE
The trunk board loops can be used in
the same way as the cargo securing
loops. The tensile strength of the loops
is 147 N (15 kgf, 33 lbf). Do not apply
excessive force to the trunk board loops
as it will damage them (page 6-43).

qJack
To remove the jack
1. Turn the knob and remove the cover.
2. Turn the wing bolt counterclockwise.
To secure the jack
Perform the removal procedure in reverse.
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 spares should
NEVER be used for long drives or
extended periods.
WARNING
Driving with a Temporary Spare Tire
on Ice or Snow:
Driving with a spare tire on the front
(driving) wheels on ice or snow is
dangerous. Handling will be affected.
You could lose control of the vehicle
and have an accident. Put the spare
tire on the rear axle and move a
regular tire to the front.
CAUTION
To avoid damage to the temporary
spare or to the vehicle, observe the
following precautions:
lDon't exceed 80 km/h (50 mph).
lAvoid driving over obstacles.
Also, don't 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).
lDon't use a tire chain on this tire
because it won't fit properly.
lDon't use your temporary spare on
any other vehicle; it has been
designed only for your Mazda.
lUse only one temporary spare tire on
your vehicle at the same time.

3. Install the lug nuts with the beveled
edge inward; tighten them by hand.
WARNING
Don't Apply Oil or Grease to Lug
Nuts, Bolts:
Applying oil or grease to lug nuts and
bolts is dangerous. The lug nuts could
loosen while driving and cause the tire
to come off, resulting in an accident.
In addition, lug nuts and bolts could
be damaged if tightened more than
necessary. Do not apply oil or grease
to lug nuts and bolts and do not
tighten the lug nuts beyond the
recommended tightening torque.4. Turn the jack handle counterclockwise
and lower the vehicle. Use the lug
wrench to tighten the nuts in the order
shown.
If you're unsure of how tight the nuts
should be, have them inspected at an
Authorized Mazda Dealer.

WARNING
Loose 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. Always securely and
correctly tighten the lug nuts.

WARNING
Metric Studs and Lug Nuts:
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. Be sure to
reinstall the same nuts you removed or
replace them with metric nuts of the
same configuration.
Incorrect Tire Air Pressure:
Driving on tires with incorrect air
pressure is dangerous. Tires with
incorrect pressure could affect
handling and result in an accident.
Don't drive with any tires that have
incorrect air pressure. When you
check the regular tires' air pressure,
check the spare tire, too.
5. Store the damaged tire, using the tire
hold-down bolt to hold it in place.
Have the damaged tire repaired as soon
as possible.

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
5-22).
NOTE
To prevent the jack and tool from
rattling, store them properly.

lConnect the other end to a solid,
stationary, exposed metallic point
(for example, the right hand side
engine mounting bolt) away from
the discharged battery (4).
6. Start the engine of the booster vehicle
and run it a few minutes. Then start the
engine of the other vehicle.

Push-Starting
WARNING
Towing a Vehicle to Start It:
Towing a vehicle to start it is
dangerous. The vehicle being towed
could surge forward when its engine
starts, causing the two vehicles to
collide. The occupants could be
injured. Never tow a vehicle to start it.
You can't start a vehicle with an automatic
transaxle by pushing it.
CAUTION
You shouldn't push-start a vehicle that
has a manual transaxle. It can damage
the emission control system.

WARNING
Keep Flames Away:
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. When working near a battery, do
not allow metal tools to contact the positive (
) or negative () terminal of the
battery. Do not allow the positive (
) terminal to contact the vehicle body.
Battery-Related Explosion:
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.
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
