: Change to continuous illumination after flashing for about 1 minute.

•

When the vehicle speed exceeds 30 km/h (18.6 mph) for more than 35 seconds, the signals received from 
the TPMS transmitter shall be checked for 15 minutes. During that 15 minutes of reception check, when 
the specified value of a tire is normally received, the tire is judged as the road wheel. After the 15 minuses 
of measurement, if four tires are judged as the road wheels, the remaining wheel is judged as the spare 
tire. After the 15 minuses of measurement, if three or less tires are judged as the road wheels, the result 
of last measurement will be applied for the unjudged tire(s).
