Locking Lug Nuts *
If your vehicle has Mazda optional
antitheft wheel lug nuts, one on each
wheel will lock the tires and you must
use a special key to unlock them. This
key will attach to the lug wrench.
Register them with the lock manufacturer
by ¿ lling out the card provided in the
glove compartment and mailing it in the
accompanying envelope. If you lose this
key, consult an Authorized Mazda Dealer
or use the lock manufacturer's order form,
which is with the registration card.
Accessory wheel locks cannot be used on
steel wheels. This includes situations when
the spare tire is installed. If the spare tire
is installed, one of the original lug nuts
(which should still be in the vehicle) must
be installed in place of the wheel lock.
