• If a window tint that affects the radio
wave signals is installed.
• If there is a lot of snow or ice on the
vehicle, particularly around the wheels
or wheel housings.
• If the tire inflation pressure is
extremely higher than the specified
level.
• If tires not equipped with tire pressure
warning valves and transmitters are
used.
• If the ID code on the tire pressure
warning valves and transmitters is not
registered in the tire pressure warning
computer.
Performance may be affected in the
following situations.
• Near a TV tower, electric power plant,
gas station, radio station, large dis-
play, airport or other facility that gen-
erates strong radio waves or electrical
noise.
• When carrying a portable radio, cellu-
lar phone, cordless phone or other
wireless communication device.
When the vehicle is parked, the time
taken for the warning to start or go off
could be extended.
When tire inflation pressure declines
rapidly for example when a tire has
burst, the warning may not function.
Warning performance of the tire
pressure warning system
The warning of the tire pressure warning
system will change in accordance with
driving conditions. For this reason, the
system may give a warning even if the
tire pressure does not reach a low
enough level, or if the pressure is higher
than the pressure that was adjusted to
when the system was initialized.
Installing tire pressure warn-
ing valves and transmitters
When replacing tires or wheels, tire
pressure warning valves and trans-
mitters must also be installed.
6-3. Do-it-yourself maintenance
When new tire pressure warning
valves and transmitters are
installed, new ID codes must be
registered in the tire pressure warn-
ing computer and the tire pressure
warning system must be initialized.
Have tire pressure warning valves
and transmitter ID codes regis-
tered any authorized Mazda retailer
or Mazda authorized repairer, or
any reliable repairer. (→P.338)
Replacing tires and wheels
If the ID code of the tire pressure warn-
ing valve and transmitter is not regis-
tered, the tire pressure warning system
will not work properly. After driving for
about 10 minutes, the tire pressure
warning light blinks for 1 minute and
stays on to indicate a system malfunc-
tion.
NOTICE
Repairing or replacing tires,
wheels, tire pressure warning
valves, transmitters and tire
valve caps
When removing or fitting the
wheels, tires or the tire pressure
warning valves and transmitters,
contact any authorized Mazda
retailer or Mazda authorized
repairer, or any reliable repairer as
the tire pressure warning valves
and transmitters may be damaged
if not handled correctly.
Make sure to install the tire valve
caps. If the tire valve caps are not
installed, water could enter the tire
pressure warning valves and the
tire pressure warning valves could
be bound.
