SERVICE TIRE MON SYS (Except Z06): If this
message comes on, a part on the Tire Pressure
Monitor (TPM) is not working properly. If you drive
your vehicle while any of the four sensors are missing or
inoperable, the warning will come on in about 10 minutes.
If all four sensors are missing, the warning will come on in
about 15 to 20 minutes. All the sensors would be missing,
for example, if you put different wheels on your vehicle
without transferring the sensors. If the warning comes on
and stays on, there may be a problem with the TPM.
See your dealer.
