the Powertrain Control Module (PCM) has detected
a problem within the fuel system. Have your vehicle
serviced by your GMdealer. This message will also be
displayed when the cluster is not getting fuel
information from the PCM.

indicate to the driver that the Selective Ride Control
system has detected a malfunction and that the system
must be serviced. See your GMdealer. The SERVICE

failure is detected by the Selective Ride Control
system. If a fault is present in the Selective Ride Control
system which causes the shocks to be in their full soft
condition, the SERVICE RIDE CONTROL, SHOCKS
INOPERATIVE and MAXIMUM SPEED 80MPH

SERVICE TIRE MONITOR: 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 60minutes. 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 GMdealer.

driving accordingly.

and a chime will sound. The driver can acknowledge
both messages by pressing the RESET button
two times. When the service messages are displayed,
the computer controlled systems will not assist the driver
in controlling the vehicle. Have the system repaired
by your GMdealer as soon as possible. Adjust your
driving accordingly.
