Manual Paddle Shift Gear Indicator (If Equipped)
These lights on the HUD are for use when using
the manual paddle shift controls to shift the
transmission. See “Manual Paddle Shift” in
Automatic Transmission Operation on page 2-26.
Shift Light
This light is used for performance driving to indicate
that the vehicle’s best performance level has been
reached to shift the transmission into the next higher
gear. An arrow pointing up will light up on the display
just prior to reaching the engine fuel cut-off mode.
This cut-off is about 6,500 RPM for the LS2 engine
and 7,000 RPM for the LS7 engine.

The fuel economy data used to determine fuel range
is an average of recent driving conditions. As your
driving conditions change, this data is gradually updated
automatically.
If the vehicle has been idling for a long time, the range
displayed on the DIC could be abnormally low. The
vehicle must be driven 5–10 miles (8–16 km) to get an
accurate reading.
GAGES Button
The gages button displays oil pressure, oil temperature,
coolant temperature, transmission uid temperature
for automatic transmission vehicles only, battery voltage,
and tire pressure information.
Oil Pressure:This display shows the oil pressure.
Press the gages button to display the oil pressure,
such as:
OIL PRESSURE 40 PSI or
OIL PRESSURE 276 kPa
Oil Temperature:This display shows the oil
temperature.
Press the gages button again to display the oil
temperature, such as:
OIL TEMPERATURE 234°F or
OIL TEMPERATURE 112°CIf the oil temperature is low, the display will show OIL
TEMPERATURE LOW. If the oil temperature is high,
the display will show OIL TEMPERATURE HIGH.
Coolant Temperature:This display shows the engine
coolant temperature.
Press the gages button again to display the coolant
temperature, such as:
COOLANT TEMPERATURE 123°F or
COOLANT TEMPERATURE 51°C
If the coolant temperature is low, the display will show
COOLANT TEMPERATURE LOW. If the coolant
temperature is high, the display will show COOLANT
TEMPERATURE HIGH.
Transmission Fluid Temperature:If you have an
automatic transmission vehicle, this display shows the
automatic transmission uid temperature.
Press the gages button again to display the automatic
transmission uid temperature, such as:
TRANS FLUID TEMP 123°F or
TRANS FLUID TEMP 51°C
If the transmission uid temperature is low, the
display will show TRANS FLUID TEMP LOW. If the
transmission uid temperature is high, the display will
show TRANS FLUID TEMP HIGH.

TRANSMISSION HOT IDLE ENGINE:You will hear
four chimes when this message is displayed. To
acknowledge this warning, press the RESET button.
After you press the RESET button, the message will be
displayed every 10 minutes until the condition changes.
If you do not press the RESET button, the message
remains on the display until the condition changes.
If the transmission uid temperature rises above
270°F (132°C) or rises rapidly, this message is displayed.
The transmission may shift gears or apply the torque
converter clutch to reduce the uid temperature. Driving
aggressively or driving on long hills can cause the
transmission uid temperature to be higher than normal.
If this message appears, you may continue to drive
at a slower speed. You should also monitor the
transmission uid temperature and allow it to cool to at
least 230°F (110°C). The transmission uid temperature
can be monitored with the gages button on the DIC.
SeeAutomatic Transmission Fluid on page 5-28. You
should also check the engine coolant temperature. If it is
also hot, seeEngine Overheating on page 5-32.If the TRANSMISSION HOT IDLE ENGINE message is
displayed during normal vehicle operation on at roads,
your vehicle may need service. See your GM dealer for
an inspection.
If driving in a performance or competitive manner, the use
of (S) Sport Automatic Mode or (S) Sport Manual Paddle
Shift gear selection is recommended. SeeAutomatic
Transmission Operation on page 2-26for more
information.
TURN SIGNAL ON:If a turn signal is left on for
three-quarters of a mile (1.2 km), this message will
appear on the display and you will hear a chime. Move
the turn signal/multifunction lever to the off position.
To acknowledge this message, press the RESET button.
UNLATCH HEADER TO MOVE TOP:This message
will display and a chime will sound if you try to lower
the convertible top without rst unlocking the top. Move
the latch handle to unlock the convertible top. See
Convertible Top (Manual) on page 2-60orConvertible
Top (Power) on page 2-67.
