SERVICE TIRE MONITOR SYSTEM
This message displays if a part on the Tire
Pressure Monitor (TPM) system is not working
properly. If you drive your vehicle while any of the
four sensors are missing or inoperable, the
warning comes on in about 10 minutes. A sensor
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.
This message displays while the ignition is in RUN.
Press any of the DIC buttons to acknowledge this
message and to clear it from the screen.
This message continues to display for two seconds
if it has not been acknowledged when the engine is
turned off. It also re-displays for two seconds if the
message has been acknowledged, but the
condition still exists when the engine is turned off.
If the condition still exists, the message re-appears
when the engine is turned on.

If your vehicle has the Traction Control
System (TCS), this message displays when the
system is not functioning properly. A warning light
also appears on the instrument panel cluster.
See Traction Control System (TCS) Warning Light

(TCS) on page 294 for more information. Have the
TCS serviced by your dealer as soon as possible.
This message displays only while the ignition is in
RUN. Press any of the DIC buttons to acknowledge
this message and to clear it from the screen.
This message continues to display for two seconds
if it has not been acknowledged when the engine is
turned off. It also re-displays for two seconds if the
message has been acknowledged, but the
condition still exists when the engine is turned off.
If the condition still exists, the message re-appears
when the engine is turned on.
