Changing a Tire
WA R N I N G
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 plac e 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 firml y set the parking
brake.
2. Put a vehicle with an automatic
transmission in Pa rk (P), a manual
transmission in Reverse (R) or 1, and
turn off the engine.
3. Turn on the hazard warning flasher.

wood blocks of sufficient size if
possible to hold the tire in place.
▼ Removing a Tire
WA R N I N G
When jacking-up a vehicle, always shift the
shift lever to 1st or R (manual transmission
vehicle) or shift the selector lever to P
(automatic transmission 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, or the select lever
is in P, which could result in an accident.

▼Locking Lug Nuts*
If your vehicle has Mazda optional
antitheft wheel lu
g nuts, one on each
wheel will lock the tires and you must use
a special key to unlock them. This key will
attach to the lug wrench. Register them
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.

WA R N I N G
Make sure the mounting surfaces of the
wheel, hub and lug nuts are clean
before changing or replacing tires:
When changing or replacing a tire, not
removing dirt and grime from the
mounting surfaces of the wheel, hub
and hub bolts is dangerous. The lug
nuts could loosen while driving and
cause the tire to come off, resulting in
an accident.
2. Mount the tire.
3. Install the lug nuts with the beveled edge inward; tighten them by hand.

WA R N I N G
Do not apply oil or grease to lug nuts
and bolts and do not tighten the lug
nuts beyond the recommended
tightening torque:
Applying oil or grease to lug nuts and

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.
