Make sure the screw thread is
adequately lubricated.

▼ 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 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

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.

Changing a Flat Tire

NOTE
If the following occurs while driving, it
could indicate a flat tire.

•

Steering becomes difficult.

•

The vehicle begins to vibrate
excessively.

•

The vehicle pulls in one direction.

If you have a flat tire, drive slowly to a
level spot that is well off the road and out
of the way of traffic to change the tire.
Stopping in traffic or on the shoulder of a
busy road is dangerous.

WARNING

Be sure to follow the directions for
changing a tire:
Changing a tire is dangerous if not done
properly. The vehicle can slip off the jack
and seriously injure someone.
No person should place any portion of their
body under a vehicle that is supported by a
jack.

Never allow anyone inside a vehicle
supported by a jack:
Allowing someone to remain in a vehicle
supported by a jack is dangerous. The
occupant could cause the vehicle to fall
resulting in serious injury.

NOTE
Make sure the jack is well lubricated
before using it.

1. Park on a hard, level surface off the

right-of-way and firmly set the parking
brake.

2. Put a vehicle with an automatic

transaxle in Park (P), a manual
transaxle in Reverse (R) or 1, and turn
off the engine.

3. Turn on the hazard warning flasher.
4. Have everyone get out of the vehicle

and away from the vehicle and traffic.

5. Remove the jack, tool, and spare tire

(page 7-3).

6. Block the wheel diagonally opposite

the flat tire. When blocking a wheel,
place a tire block both in front and
behind the tire.

NOTE
When blocking a tire, use rocks or
wood blocks of sufficient size if
possible to hold the tire in place.

▼ Removing a Flat Tire

WARNING

When jacking-up a vehicle, always shift the
shift lever to 1st or R position (manual
transaxle vehicle) or shift the selector lever
to P position (automatic transaxle vehicle),
apply the parking brake, and place wheel
blocks in the position diagonally opposed
to the jack:
Changing a flat tire without using wheel
blocks is dangerous because the vehicle
may move and fall off the jack even with
the shift lever in 1st or R position, or the
selector lever is in P position, which could
result in an accident.

1. If your vehicle is equipped with a

wheel cover, pry off the wheel cover
with the beveled end of the jack lever.

NOTE
Force the end of the jack lever firmly
between wheel and cover, or removal
will be difficult.

8. Turn the jack handle clockwise and

raise 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 off the jack resulting in an
accident.

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 off the jack.

9. Remove the lug nuts by turning them

counterclockwise; then remove the
wheel and center cap.

▼ Locking Lug Nuts

If your vehicle has Mazda optional
antitheft wheel lug nuts, each wheel will
have one locking lug nut that locks the
wheel and tire, and you must use a special
key to unlock the locking lug nut. This key
is stored in the glove compartment.
Register the key and lug nuts with the lock
manufacturer by filling out the card
provided in the glove compartment and
mailing it in the accompanying envelope.
If you lose this key, consult an Authorized
Mazda Dealer or use the lock
manufacturer's order form, which is with
the registration card.
Accessory wheel locks cannot be used on
steel wheels. This includes situations when
the spare tire is installed. If the spare tire is
installed, one of the original lug nuts
(which should still be in the vehicle) must
be installed in place of the wheel lock.

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.
