Changing a Tire
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, le vel surface off the
right-of-way and firm ly set the parking
brake.
2. Put a vehicle with an automatic
transmission in Park (P), a manual
transmission in Reve rse (R) or 1, and
turn off the engine.
3. Turn on the hazard warning flasher.
4. Have passengers get out of the vehicle and away from the vehicle and traffic.
5. Remove the jack and tool (page 7-3).
6. Block the wheel diagonally opposite the tire to be changed. 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 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.

WA R N I N G
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.
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 off the jack.
8. Remove the lug nuts by turning them counterclockwise; then remove the
wheel.
▼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 l
ug 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. When installing
a spare tire, original lug nut must be used
in place of the wheel lock.
Special key
Antitheft lug nut
To remove an antitheft lug nut
1. Obtain the special key for the antitheft
lug nut.
2. Place the special key on top of the antitheft lug nut, and be sure to hold
the key square to it. If you hold the key
at an angle, you may damage both key
and nut. Do not use a power impact
wrench.

To install the antitheft lug nut
1. Place the special key on top of the nut, and be sure to hold the key square to it.
If you hold the key at an angle, you
may damage both key and nut. Do not
use a power impact wrench.
2. Place the lug wrench on top of the
special key, apply pressure, and turn it

▼Mounting the Tire
1. Remove dirt and grime from the
mounting surfaces of the wheel and
hub, including the hub bolts, with a
cloth.

WARNING
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.

WARNING
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
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.

WA R N I N G
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 9-9.
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.

Towing Description
We recommend that towing be done only
by an Authorized Mazda Dealer or a
commercial tow-truck service.

Proper lifting and towing are necessary to
prevent damage to the vehicle.
Government and local laws must be
followed.

A towed vehicle usually should have its
drive wheels (rear wheels) off the ground.
If excessive damage or other conditions
prevent this, use wheel dollies.
Wheel dollies

When towing with the rear wheels on the
ground, release the parking brake.
CAUTION
Do not tow the vehicle pointed backward
with driving wheels on the ground. This
may cause internal damage to the
transmission.
Do not tow with sling-type equipment.
This could damage your vehicle. Use
wheel-lift or flatbed equipment.

Electronic Brake Force
Distribution System Wa r n i n g If the electronic brake force di
stribution control unit determines that some compo‐
nents are operating incorrectly , the control unit may illuminate the brake system
warning light and the ABS warni ng light simultaneously. The problem is likely to be
the electronic brake force distribution system.
WA R N I N G
Do not drive with both the ABS warning light and brake warning light illuminated.
Have the vehicle towed to an Authorized Mazda Dealer to have the brakes inspected as
soon as possible:
Driving when the brake system warning li ght and ABS warning light are illuminated
simultaneously is dangerous.
When both lights are illuminate d, the rear wheels could lock more quickly in an emer‐
gency stop than under normal circumstances.
Charging System Warn‐ ing Indication/Warning Light If the warning light illuminates while driving, it indicates a
malfunction of the alter‐
nator or of the charging system.
Drive to the side of the road and park off the right-of-way. Co nsult an Authorized
Mazda Dealer.
CAUTION
Do not continue driving when the charging system warning light is illuminated be‐
cause the engine could stop unexpectedly.
Engine Oil Warning Light This warning light indicates low engine oil pressure.
CAUTION
Do not run the engine if the oil pressure is
low. Otherwise, it could result in extensive
engine damage.
If the light illuminates or the w arning indication is displayed while driving:
1. Drive to the side of the road and park off the right-of-way o n level ground.
2. Turn off the engine and wait 5 minutes for the oil to drain b ack into the oil pan.
3. Inspect the engine oil level (p age 6-21). If it's low, add the appropriate amount of
engine oil while being careful not to overfill.
CAUTION
Do not run the engine if the oil level is low. Otherwise, it could result in extensive
engine damage.
4. Start the engine and check the warning light.

If the light remains illuminated even though the oil level is normal or after adding oil,
