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
automatically turned off. When the coolant
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
