LOW OIL PRESSURE: If this message appears while
the engine is running, stop the engine and do not
operate it until the cause of low oil pressure is corrected.
Severe damage to the engine can result. A multiple
chime will sound when this message is displayed.
LOW VOLTAGE: This message will appear when the
electrical system is charging less than 10 volts or if
the battery has been drained. If this message appears
immediately after starting, it is possible that the
generator can still recharge the battery. The battery
should recharge while driving but may take a few hours
to do so. Consider using an auxiliary charger to boost
the battery after returning home or to a final destination.
Be sure to follow the manufacturer's instructions. If this
message appears while driving or after starting your
vehicle and stays on, have it checked immediately by
your GM dealer to determine the cause of this problem.
To help the generator recharge the battery quickly,
you can reduce the load on the electrical system
by turning off the accessories. You can monitor battery
voltage on the DIC by pressing the INFO button.
The normal range is 11.5 to 15.5 volts.
LOW WASHER FLUID: This message means that your
vehicle is low on windshield washer fluid. See Windshield
Washer Fluid on page 6-32.
MAX (Maximum) SPEED XX MPH (XX KM/H):
A failure in the magnetic ride control system has
occurred when this message appears. The Powertrain
Control Module (PCM) determines the speed to
which your vehicle is limited. Have your vehicle serviced
by your GM dealer if this message appears.
