Tires and wheels
Checking tire pressure electronically
with the Advanced Tire Pressure
Monitoring System (Advanced TPMS)
The Advanced TPMS only functions on
wheels that are equipped with the proper
electronic sensors. It monitors the tire in-
flation pressure, as selected by the driver,
in all four tires. A warning is issued to alert
you to a decrease in pressure in one or
more of the tires.
Tire inflation pressure inquiries are made
using the multifunction display. The
present inflation pressures are displayed
only after a few minutes of travel time.

The Advanced Tire Pressure Monitoring
System (Advanced TPMS) is equipped with a
combination low tire pressure/TPMS malfunc-
tion telltale in the instrument cluster
(
୴ page 576). Depending on how the telltale illu-
minates, it indicates a low tire inflation pressure
condition or a malfunction in the Advanced
TPMS system itself:
ț If the telltale illuminates continuously, one
or more of your tires is significantly underin-
flated. There is no malfunction in the
Advanced TPMS.
ț If the telltale flashes for 60 seconds and
then stays illuminated, the Advanced TPMS
system itself is not operating properly.

Possible differences between the readings
of a tire inflation pressure gauge of an air hose,
e.g. gas station equipment, and the vehicle’s
control system can occur. Usually the readings
issued by the control system are more precise.
