▼ 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 fo
r long drives or
extended periods.
WA R N I N G
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.
 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.

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.
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 firmly set the parking
brake.

5. Use the lug wrench to tighten the nutsin the order shown.

If you are unsure of how tight the nuts
should be, have them inspected at an
Authorized Mazda Dealer.

―147 (12 ―14,

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. (Without flat tire belt)
Store the damaged tire in the luggage
compartment.
(With flat tire belt)
Remove the luggage compartment
cover (if equipped).

17. Have the flat tire repaired or replaced as soon as possible.
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.

Route the jumper cables away from parts that will be moving:
Connecting a jumper cable near or to moving parts (cooling fans, belts) is dangerous. The
cable could get caught when the engine starts and cause serious injury.
CAUTION
Use only a 12 V booster system. You can damage a 12 V starter, ignition system, and other
electrical parts beyond repair with a 24 V power supply (two 12 V batteries in series or a 24 V
motor generator set).
1. Move the booster vehicle so that its battery is as close as possible to your vehicle's battery.
2. Make sure that the power such as for the headlights and air conditioner is turned off.
3. Remove the battery cover.
4. Turn off the booster vehicle's engine and connect the jumper cables in the following
order.
Make sure that the jumper cables are securely connected so that they do not disconnect

the vehicle must be towed by another
vehicle in an emergency case such as
when the vehicle is stuck in snow,
however, it may damage the bumper.
Tiedown hook
CAUTION
When using the hook in such emergency
cases, observe the following so as not to
damage the tiedown hook or the vehicle
body.

The vehicle must be pulled straight to the
rear so that no load is applied to the
vehicle in the lateral direction.
 The bumper may be damaged if the tie
down hook is used as a towing hook.
 When using a metal chain or wire cable,
wrap a cloth around the attachment
area. If the metal chain or wire cable
contacts the bumper directly, the
bumper could be scratched or damaged.
