A/C OFF FOR ENGINE PROTECTION
This message displays when the engine coolant
becomes hotter than the normal operating
temperature. See Engine Coolant Temperature
Gage on page 222. 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
screen.
This message continues to display for two seconds
if it has not been acknowledged when the engine is
turned off. It also re-displays for two seconds if the
message has been acknowledged, but the
condition still exists when the engine is turned off.
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.

This message displays when the system detects
that the battery voltage is dropping beyond a
reasonable level. The battery saver system starts
reducing certain features of the vehicle that you
may be able to notice. At the point that the features
are disabled, this message is displayed. It means
that the vehicle is trying to save the charge in the
battery.
Turn off all unnecessary accessories to allow the
battery to recharge.
The normal battery voltage range is 11.5 to
15.5 volts. You can monitor the battery voltage by
pressing the information button until BATTERY
