CAUTION
When inspecting or adjusting the tire
air pressures, do not apply excessive
force to the stem part of the wheel
unit. The stem part could be
damaged.
Changing tires and wheels
The following procedure allows the
TPMS to recognize a tire pressure sensor's
unique ID signal code whenever tires or
wheels are changed, such as changing to
and from winter tires.
NOTE
Each tire pressure sensor has a unique ID
signal code. The signal code must be
registered with the TPMS before it can work.
The easiest way to do it is to have an
Authorized Mazda Dealer change your tire and
complete ID signal code registration.
When having tires changed at an
Authorized Mazda Dealer
Tire pressure sensor ID signal code
registration is completed when an
Authorized Mazda Dealer changes your
vehicle's tires.
When changing tires yourself
If you or someone else changes tires, you
or someone else can also undertake the
steps for the TPMS to compl ete the ID
signal code registration.
1. After tires have been changed, turn the
ignition switch to the ON position, then
turn it back to the ACC or LOCK
position.
2. Wait for about 15 minutes.
3. After about 15 minutes, drive the
vehicle at a speed of at least 25 km/h
(16 mph) for 10 minutes and the tire
pressure sensor ID signal code will be
registered automatically.
NOTE
If the vehicle is driven within about 15 minutes
of changing tires, the tire pressure monitoring
system warning light will flash because the
sensor ID signal code would not have been
registered. If this happens, park the vehicle for
about 15 minutes, after which the sensor ID
signal code will register upon driving the
vehicle for 10 minutes.
