how to properly initialize the system.
The Tire Pressure Monitoring System (TPMS) mooi?ors the tire pressure of all four tires indirectly using the data
sent from the ABS wheel speed sen_~ors.' If the.air pressure of one or more tires is too low compared with the
specified value (the initial value learned by the system), the system warns the driver with the TPMS warning
lighiin the ·instrument clustei'anda beep souncf To allowihe TPMS to operate correctly, it is essential that the
TPMS be initialized to learn new conditions whenever a tire related service,.,,...
