▼Locking Lug Nuts
If your Mazda is equipped with the
optional antitheft wheel lug nuts, a
special key must be
used to unlock the
locking lug nut for each wheel. The key
is stored in the glove compartment,
center console storage, storage box, or
trunk. Register the key and lug nuts
with the lock manufacturer by filling
out the registration card and mailing it
in using the accompanying envelope. If
the key is lost, consult an Authorized
Mazda Dealer or use the lock
manufacturer’s order form to order a
new key.
Antitheft wheel lug nuts cannot be
installed on a steel wheel spare tire.

use one of the original lug nuts in place
of the locking lug nut. The original lug
nuts are stored inside your Mazda.

WARNING
Never tamper with the air bag/
pretensioner systems and always have
an Authorized Mazda Dealer perform
all servicing and repairs:
Self-servicing or tampering with the
systems is dangerous. An air bag/

▼Tire Pressure Monitoring System
(TPMS) Warning Indication/
Warning Light (Flashing)
If there is a problem with the TPMS or
the voltage of a tire pressure sensor
decreases, the TPMS warning light
flashes and a message is displayed on
the multi-information display. Have
your vehicle inspected by an
Authorized Mazda Dealer.
WARNING
Do not drive the vehicle at high
speeds if the TPMS warning light turns
on or
flashes:
Driving the vehicle at high speeds
while the TPMS warning light is turned
on or flashing is dangerous because
the brake performance and the
steering wheel operability will be
reduced. If the vehicle is driven at high
speeds or the brakes are suddenly
applied, it could lead to an accident.
Gradually apply the brakes to lower the
vehicle's speed.
Do not ignore the TPMS warning light
when it is turned on or flashing:
Continuing to driv e the vehicle while
ignoring the illumi nation/flashing of
the TPMS warning light is dangerous
because a tire may burst which could
lead to an accident. Take appropriate
measures as soon as possible.

CAUTION
Adjust the tire pressures while the
tires are cool. Because the air
pressure in the tires fluctuates
depending on the temperature,
before adjusting the tire pressures,
let the vehicle sit for an hour or drive
it only within a 1.6 km (1 mile)
distance. If the tire pressures are
adjusted while the tires are warm,
the tire pressures may decrease
below the
specified air pressure after
cooling down which could turn on
the warning light. In addition,
because the air pressure in the tires
decreases when the ambient
temperature is low, if the ambient
temperature increases, an
illuminated TPMS warning light may
turn off. Under any circumstances,
always adjust the tire pressures while
the tires are cool.
 After adjusting the tire pressures, the
TPMS warning light turns off. If the
TPMS warning light does not turn
off,
drive the vehicle at a speed of about
25 km (16 mph) or faster for 3
minutes or longer and make sure the
warning light turns off.
If the TPMS warning light remains on
even after adjusting the tire pressures,
one of the tires may have a puncture.
