▼Spare 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 a
ffected.
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
 When using the temporary spare tire,
driving stability may decrease
compared to when using only the
conventional tire. Drive carefully.
 To avoid damage to the temporary
spare tire or to the vehicle, observe
the following precautions:
 Do not exceed 80 km/h (50 mph).
 Avoid driving over obstacles. Also,
do not drive through an automatic
car wash. This tire's diameter is
smaller than a conventional tire, so
the ground clearance is reduced.
 Do not use a tire chain on this tire
because it will not
fit properly.
 Do not use your temporary spare
tire on any other vehicle, it has
been designed only for your
Mazda.
 Use only one temporary spare tire
on your vehicle at the same time.

NOTE
When raising the jack head into the
jacking position and aligning the
groove in the jack head with the rail
under the vehicle body, the top of
the jack head contacts the vehicle's
underbody without the rail
contacting the bottom of the
groove.

8. Turn the jack handle clockwise andraise the vehicle high enough so
that the spare tire can be installed.
Before removing the lug nuts, make
sure your Mazda is firmly in
position and that it cannot slip or
move.

WARNING
Do not jack up the vehicle higher
than is necessary:
Jacking up the vehicle higher than is
necessary is dangerous as it could
destabilize the vehicle resulting in
an accident.
Do not start the engine or shake
the vehicle while it is jacked up:
Starting the engine or shaking the
vehicle while it is jacked up is
dangerous as it could cause the
vehicle to fall o ff the jack resulting
in an accident.
Never go under the vehicle while it
is jacked up:
Going under the vehicle while it is
jacked up is dangerous as it could
result in death or serious injury if
the vehicle were to fall o ff the jack.
9. Remove the lug nuts by turning them counterclockwise; then
remove the wheel and center cap.
▼Locking Lug Nuts
If your Mazda is equipped with the
optional antitheft wheel lug nuts, a
special key must be used to unlock the
locking lug nut for each wheel. The key
is stored in the glove compartment,
center console storage, storage box, or
trunk. Register the key and lug nuts
with the lock manufacturer by
filling
out the registration card and mailing it
in using the accompanying envelope. If
the key is lost, consult an Authorized
Mazda Dealer or use the lock
