short circuit resulting in a fi re.

Cleaning the Floor Mats
Rubber À oor mats should be cleaned with
mild soap and water only.
WARNING
Do not use rubber cleaners, such as tire
cleaner or tire shine, when cleaning
rubber fl oor mats:
Cleaning the rubber fl oor mats with
rubber cleaning products makes the
fl oor mats slippery.
This may cause an accident when
depressing the accelerator, brake, or
clutch (Manual transaxle) pedal or
when getting in or out of the vehicle.

After removing the À oor mats for cleaning,
always reinstall them securely (page

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 aff ected.
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
 


¾ When using the temporary spare tire,
driving stability may decrease compared
to when using only the conventional tire.
Drive carefully.
 


¾ To avoid damage to the temporary
spare tire or to the vehicle, observe the
following precautions:
 


¾ Do not exceed 80 km/h (50 mph).



¾ 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.
 


¾ Do not use a tire chain on this tire
because it will not fi t properly.
 


¾ Do not use your temporary spare
tire on any other vehicle, it has been
designed only for your Mazda.
 


¾ Use only one temporary spare tire on
your vehicle at the same time.

Changing a Flat Tire
N O T E
If the following occurs while driving, it
could indicate a À at tire.




y Steering becomes dif¿ cult.



y The vehicle begins to vibrate
excessively.
 


y The vehicle pulls in one direction.
If you have a À at tire, drive slowly to a
level spot that is well off the road and out
of the way of traf¿ c to change the tire.
Stopping in traf¿ c 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.

N O T E
Make sure the jack is well lubricated
before using it.

1. Park on a level surface off the right-of-
way and ¿ rmly 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.

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 confi guration:
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.

mat.
