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. Shift into Park (P) 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
selector lever to P, 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 select lever is in P, which could result in
an accident.

▼ 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.

Overheating

If the temperature gauge indicates
overheating or the high engine coolant
temperature warning light turns on, the
vehicle loses power, or you hear a loud
knocking or pinging noise, the engine is
probably too hot.

WARNING

Pull over to a safe location, then switch

the ignition off and make sure the fan is
not running before attempting to work
near the cooling fan:
Working near the cooling fan when it is
running is dangerous. The fan could
continue running indefinitely even if the
engine has stopped and the engine
compartment temperature is high. You
could be hit by the fan and seriously
injured.

Do not remove either cooling

system cap when the engine and radiator
are hot:
When the engine and radiator are hot,
scalding coolant and steam may shoot out
under pressure and cause serious injury.

Open the hood ONLY after steam is no
longer escaping from the engine:
Steam from an overheated engine is
dangerous. The escaping steam could
seriously burn you.

If the temperature gauge indicates
overheating or the high engine coolant
temperature warning light turns on:

1. Drive safely to the side of the road and

park off the right-of-way.

2. Shift into park (P).
3. Apply the parking brake.
4. Turn off the air conditioner.
5. Check whether coolant or steam is

escaping from the engine
compartment.
