measures as soon as possible.
NOTE
While the TPMS is learning the tire
positions, such as immediately after a
tire position has been changed, the tire
pressure at the tire position prior to it
being changed is displayed until the
system completes the learning. For this
reason, the tire pressures displayed for
the tire positions may be different from
the actual tire pressures at the tire
positions.
Action to be taken

Event Data Recorder
(U.S.A. and Canada)
▼ Event Data Recorder
This vehicle is equipped with an event
data recorder (EDR). The main
purpose of an EDR is to record, in
certain crash or near crash-like
situations, such as an air bag
deployment or hitting a road obstacle,
data that will assist in understanding
how a vehicle’s systems performed.
The EDR is designed to record data
related to vehicle dynamics and safety
systems for a short period of time,
typically 30 seconds or less. The EDR in
this vehicle is designed to record such
data as:
How various systems in your vehicle
were operating;
Whether or not the driver and
passenger safety belts were buckled/
fastened;
How far (if at all) the driver was
depressing the accelerator and/or
brake pedal; and,
How fast the vehicle was traveling.
These data can help provide a better
understanding of the circumstances in
which crashes and injuries occur.
NOTE:
EDR data are recorded by your vehicle
only if a non-trivial crash or near
crash-like situation occurs; no data are
recorded by the EDR under normal
driving conditions and no personal
data (e.g., name, gender, age, and
crash location) are recorded. However,
other parties, such as law
enforcement, could combine the EDR
data with the type of personally
identifying data routinely acquired
during a crash investigation.
To read data recorded by an EDR,
special equipment is required, and
access to the vehicle or the EDR is
needed. In addition to the vehicle
manufacturer, other parties, such as
law enforcement, that have the special
equipment, can read the information if
they have access to the vehicle or the
EDR.

Mazda will not disclose any of the data
recorded in an EDR to a third party
unless:
A written agreement from the vehicle
owner or the lessee is obtained
Officially requested by the police or
other law enforcement authorities
Used as a defense for Mazda in a
lawsuit, claim, or arbitration
Ordered by a judge or court
However, if necessary Mazda will:
Use the data for research on Mazda
vehicle performance, including
safety.
Disclose the data or the summarized
data to a third party for research
purposes without disclosing vehicle
or owner identification information.

NOTE
Tires degrade over time, even when
they are not being used on the road. It
is recommended that tires generally be
replaced when they are 6 years or
older. Heat caused by hot climates or
frequent high loading conditions can
accelerate the aging process. You
should replace the spare tire when you
replace the other road tires due to the
aging of the spare tire. The period in
which the tire was manufactured (both
week and year) is indicated by a 4-digit
number.
Refer to Tire Labeling on page 8-24.
▼Safety Practices
The way you drive has a great deal to
do with your tire mileage and safety.
So cultivate good driving habits for
your own benefit.
Observe posted speed limits and
drive at speeds that are safe for the
existing weather conditions
Avoid fast starts, stops and turnsAvoid potholes and objects on the
road
Do not run over curbs or hit the tire
against the curb when parking
CAUTION
If you feel a sudden vibration or ride
disturbance while driving or you
suspect your tire or vehicle has been
damaged, immediately reduce your
speed. Drive with caution until you can
safely pull
off the road. Stop and
inspect the tire for damage. If the tire
is under-inflated or damaged, deflate
it, remove the tire and rim and replace
it with your spare tire. If you cannot
detect a cause, have the vehicle towed
to the nearest vehicle or tire dealer to
have the vehicle inspected.
