STARTING AND OPERATING 337
Should this occur, you should stop as soon as possible
and inflate all of the tires with a low pressure condition
(those flashing in the EVIC graphic) to the vehicle's
recommended cold placard pressure inflation value.
Once the system receives the updated tire pressures, the
system will automatically update, the graphic display in
the EVIC will stop flashing, and the "TPM Telltale Light"
will turn off. The vehicle may need to be driven for up to
20 minutes above 15 mph (24 km/h) in order for the
5
TPMS to receive this information.
