HIGH TIRE PRESSURE – (LF, LR, RF, RR)
(Except Z06):You will hear two chimes when this
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 5-61andIn ation - 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
message remains on the display until the condition
changes.
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.

low oil level and abrupt changes in the vehicle’s
direction. When this warning is displayed, you should
not operate the engine at high rpm or make fast abrupt
moves. As soon as possible, you should check the
oil level. SeeEngine Oil on page 5-13.LOW TIRE PRESSURE (Except Z06):You will hear
two chimes when this message is displayed. To
acknowledge the warning, press RESET. After you
press RESET, a message will appear every 10 minutes
until this condition changes. This message indicates
that the pressure in one of your tires is less than 25 psi
(172 kPa). Next to the LOW 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 low on pressure. 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

When the LOW TIRE PRESSURE or FLAT TIRE
message is displayed on the Driver Information
Center, your vehicle’s handling capabilities will
be reduced during severe maneuvers. If you
drive too fast, you could lose control of your
vehicle. You or others could be injured. Don’t
drive over 55 mph (90 km/h) when the LOW

coolant temperature and engine oil level. If your
engine is too hot, seeEngine Overheating on page 5-26.
Your vehicle may need service, so see your dealer.
You can monitor the oil temperature with the GAGES
button on the DIC.
SERVICE ABS (Anti-Lock Brake System):If the
SERVICE ABS message is displayed when you
are driving, stop as soon as possible and turn the
ignition off. Then start the engine again to reset the
system. If the message stays on, or comes back
on again while you are driving, your vehicle is in need
of service. If the regular brake system warning light
is not on, you still have brakes, but do not have anti-lock

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
10 minutes. If all four sensors are missing, the warning
will come on in about 15 to 20 minutes. All the
sensors would be missing, for example, if you put
different wheels on your vehicle without transferring the

TRACTION SYS message is displayed when you are
driving, there is a problem with your Traction Control
System and your vehicle is in need of service. When this
