The outside air temperature automatically appears
in the bottom right corner of the uplevel DIC
display when viewing the trip/odometer screens,
fuel screens and some of the gages screens. If the
outside air temperature is at or below 37°F
(3°C), the temperature reading will toggle between
displaying the outside temperature and the
word ICE for two minutes. If there is a problem
with the system that controls the temperature
display, the letters OC (open circuit) or SC (short
circuit) will appear on the display. If this occurs,
have the vehicle serviced by your dealer.

DIC Warnings and Messages
Messages are displayed on the uplevel DIC to
notify the driver that the status of the vehicle has
changed and that some action may be needed
by the driver to correct the condition. Multiple
messages may appear one after another.
Some messages may not require immediate
action, but you can press any of the DIC buttons
on the uplevel vehicle to acknowledge that
you received the message and clear it from the
DIC display.
Some messages cannot be cleared from the DIC
display because they are more urgent. These
messages require action before they can be
cleared.
If there are any active warning messages when
the vehicle is turned off, two chimes sound and the
DIC goes into a reminder mode. The reminder
mode displays any active message. If there
are multiple messages, the DIC displays each
message for ve seconds. After each active
message is displayed once, the reminder mode
turns off.You should take any messages that appear on the
display seriously and remember that clearing
the messages will only make the messages
disappear, not correct the problem.
The following are the possible messages that can
be displayed and some information about them.
A/C OFF FOR ENGINE PROTECTION
This message displays when the engine coolant
becomes hotter than the normal operating
temperature. SeeEngine Coolant Temperature
Gage on page 189. To avoid added strain on a hot
engine, the air conditioning compressor is

temperature returns to normal, the air conditioning
compressor turns back on. You can continue to
drive your vehicle.
This message comes on while the ignition is in
RUN. Press any of the DIC buttons to acknowledge
this warning message and to clear it from the

If the condition still exists, the message re-appears
when the engine is turned on. If this message
continues to appear, have the system repaired by
your dealer as soon as possible to avoid
damage to the engine.
