Mazda CX-3: Changing a Flat Tire / Locking Lug Nuts
If your vehicle has Mazda optional
antitheft wheel lug nuts, each wheel will
have one locking lug nut that locks the
wheel and tire, and you must use a special
key to unlock the locking lug nut. This key
is stored in the glove compartment.
Register the key and lug nuts with the lock
manufacturer by filling 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.

To remove an antitheft lug nut
- Obtain the special key for the antitheft
lug nut.
- Place the special key on top of the
antitheft lug nut, and be sure to hold
the key square to it. If you hold the key
at an angle, you may damage both key
and nut. Do not use a power impact
wrench.
- Place the lug wrench on top of the key
and apply pressure. Turn the wrench
counterclockwise.

WARNING
When jacking-up a vehicle, always shift the
shift lever to 1st or R position (manual
transaxle vehicle) or shift the selector lever
to P position (automatic transaxle vehicle),
apply the parking brake, and place wheel
blocks in the position diagonally opposed
to the jack: Changing a flat tire without using wheel
blocks is dangerous because the vehicle
may move and fall off the jack even with
the shift lever in 1st or R position, or the
selector lever is in P position, which could
result in an accident...
Remove dirt and grime from the
mounting surfaces of the wheel and
hub, including the hub bolts, with a
cloth.
WARNING
Make sure the mounting surfaces of the
wheel, hub and lug nuts are clean
before changing or replacing tires: When changing or replacing a tire, not
removing dirt and grime from the
mounting surfaces of the wheel, hub
and hub bolts is dangerous...
