message is displayed. To acknowledge the warning,
press RESET. After you press RESET, a message will
reappear every 10 minutes until this condition
changes. This message indicates that the pressure in
one of your tires is higher than 42 psi (290 kPa). Next to
the HIGH TIRE PRESSURE message, you can see
either LF (left front), LR (left rear), RF (right front) or RR
(right rear) to indicate to you which tire is higher than
42 psi (290 kPa). You can receive more than one
tire pressure message at a time. To read other
messages that may have been sent at the same time,
press RESET. If a tire pressure message appears on the
DIC, stop as soon as you can. Have the tire pressures
checked and set to those shown on your Tire Loading
Information Label. SeeExtended Mobility Tires
(Except Z06) on page 5-61andInation - Tire
Pressure on page 5-62.HIGH TRANS TEMP (Automatic Transmission
Only):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 RESET, the

If the transmission fluid 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 fluid temperature. Driving
aggressively or driving on long hills can cause the
transmission fluid 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 fluid temperature and allow it to cool to at
least 230°F (110°C). The transmission fluid temperature
can be monitored with the GAGES button on the
DIC. SeeAutomatic Transmission Fluid on page 5-20.
You should also check the engine coolant temperature.
If it is also hot, seeEngine Overheating on page 5-26.
If the HIGH TRANS TEMP message is displayed during
normal vehicle operation on flat roads, your vehicle
may need service. See your dealer for an inspection.
