428 STARTING AND OPERATING
Tire Pressure Monitoring Low Pressure Warnings
The TPM Telltale Light will illuminate in the in-
strument cluster and a chime will sound when tire
pressure is low in one or more of the four active
road tires. In addition, the EVIC will display a LOW
TIRE message and a graphic showing the pressure values
of each tire with the low tire pressure values flashing.
Should this occur, you should stop as soon as possible
and inflate the tires with a low pressure condition (those
flashing in the EVIC graphic) to the vehicle's recom-
mended 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
TPMS to receive this information.
Service 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 SERVICE TPM SYSTEM message
for a minimum of five seconds and then display dashes
(- -) in place of the pressure value to indicate which
sensor is not being received.
