268 STARTING AND OPERATING
Should this occur, you should stop as soon as possible
and inflate the tires with low pressure (those flashing in
the EVIC graphic) to the vehicle's recommended cold
placard pressure value. Once the system receives the
updated tire pressures, the system will automatically
update, the graphic display in the EVIC will stop flash-
ing, and the TPM Telltale Light will turn off. The vehicle
may need to be driven for up to 10 minutes above 15 mph
(25 km/h) in order for the TPMS to receive this informa-
tion.
Check TPMS Warning
If a system fault is detected, the TPM Telltale Light will
flash on and off for 75 seconds and then remain on solid.
The system fault will also sound a chime. In addition, the
EVIC will display a CHECK TPM SYSTEM message for
three seconds and then display dashes (- -) in place of the
pressure value to indicate which sensor is not being
received.
