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
configuration:
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 inflation pressure. Refer
to Tyres on page 9-10.
9. Have the flat tyre repaired or
replaced as soon as possible.
WARNING
Do not drive with any tyres that have
incorrect air pressure:
Driving on tyres with incorrect air
pressure is dangerous. Tyres with
incorrect pressure could affect
handling and result in an accident.
When you check the regular tyres' air
pressure, check the spare tyre, too.
NOTE
To prevent the jack and tool from
rattling, store them properly.
