In Case of Emergency
If you're unsure of how tight the
nuts should be, have them
inspected at a service station. The
specified torque is 90 to 120 N·m
(9.0 to 12.0 kgf·m, 65 to 87
ft·lbf).
! WARNING
Loose 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. Always securely and
correctly tighten the lug nuts.

! WARNING
Metric Studs and Lug Nuts:
Because the wheel studs and lug
nuts on your Mazda have metric
threads, using a nonmetric nut
would be 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.
Be sure to reinstall the same nuts
you removed or replace them with
metric nuts of the same
configuration.
! WARNING
Incorrect Tire Air Pressure:
Driving on tires with incorrect air
pressure is dangerous. Tires with
incorrect pressure could affect
handling and result in an
accident. Don't drive with any
tires that have incorrect air
pressure. When you check the
regular tire's air pressure, check
the spare tire, too.
