514 STARTING AND OPERATING
Premium Tire Pressure Monitoring
Vehicles equipped with a EVIC will display specific tire
pressure information. When tire pressure is low, the low
tire ISO telltale will illuminate and the EVIC will display
actual individual tire pressure when the tire pressure is
lower than the Placard Value. The "Tire Pressure Moni-
toring Telltale Light" will flash on and off for 75 seconds,
and remain on solid when a system fault is detected. The
system fault will also sound a chime. If the ignition
switch is cycled, this sequence will repeat, providing the
system fault still exists. The "Tire Pressure Monitoring
Telltale Light" will turn off when the fault condition no
longer exists. A system fault can occur with any of the
following scenarios:
1. Jamming due to electronic devices or driving next to
facilities emitting the same Radio Frequencies as the
TPM sensors.
2. Installing some form of aftermarket window tinting
that affects radio wave signals.
3. Lots of snow or ice around the wheels or wheel
housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM sensors.
