Spare Tyre *
Your Mazda has a temporary spare tyre.
The temporary spare tyre is lighter and
smaller than a conventional tyre, and is
designed only for emergency use and
should be used only for VERY short
periods. Temporary spare tyres should
NEVER be used for long drives or
extended periods.
WARNING
Do not install the temporary spare tyre
on the front wheels (driving wheels):
Driving with the temporary spare tyre
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
tyre to the front wheel and install the
temporary spare tyre to the rear.
CAUTION
  When using the temporary spare
tyre, driving stability may decrease
compared to when using only the
conventional tyre. Drive carefully.
  To avoid damage to the temporary
spare tyre 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 tyre's diameter is
smaller than a conventional tyre,
so the ground clearance is reduced.
 


 Do not use a tyre chain on this tyre
because it will not ¿ t properly.




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


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

Emergency Flat Tyre
Repair Kit
*
The emergency À at tyre repair kit included
with your Mazda is for a temporary repair
of a slightly damaged À at tyre resulting
from running over nails or similar sharp
objects on the road surface.
Perform the emergency À at tyre repair
without removing the nail or similar sharp
object which punctured the tyre.
NOTE
Your vehicle is not equipped with a
spare tyre. In the event of a À at tyre,
use the emergency À at tyre repair kit
to repair the tyre temporarily. When
doing the repair, refer to the instructions
included in the emergency À at tyre
repair kit. If an emergency repair was
performed on a À at tyre using the
emergency À at tyre repair kit, have
an expert repairer, we recommend an
Authorised Mazda Repairer, repair or
replace the tyre as soon as possible.

4. Turn the wheel brace anticlockwise and
lower the vehicle.
5. Use the wheel brace to tighten the nuts
in the order shown.



If you are unsure of how tight the nuts
should be, have them inspected at an
expert repairer, we recommend an
Authorised Mazda Repairer.

Nut tightening torque
N·m (kgf·m, ft·lbf) 108—147 (12—14, 80—108)

WARNING
Always securely and correctly tighten
the wheel nuts:
Improperly or loosely tightened wheel
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 con¿ guration:
Because the wheel studs and wheel
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 tyre blocks and store the
tools and jack.
7. Store the damaged tyre in the luggage
compartment.
8. Check the inÀ ation pressure. Refer to
Tyres on page 9-10 .
9. Have the À at tyre repaired or replaced
as soon as possible.

NOTE
(With tyre pressure monitoring
system)
Do not press the tyre pressure
monitoring system set switch after
installing the spare tyre. The switch
is only to be pressed after installing
the repaired À at tyre or installing a
replacement tyre (page 4-38 ).
