A/C OFF FOR ENGINE PROTECTION

This message will display when the engine coolant

becomes hotter than the normal operating temperature.

See Engine Coolant Temperature Gage on page 3-38.

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 will turn back on. You can

continue to drive your vehicle.

This message will come 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 will continue to display for two seconds if

it has not been acknowledged when the engine is

turned off. It will also re-display 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 will re-appear

when the engine is turned on. If this message continues

to appear, have the system repaired by your GM dealer

as soon as possible to avoid damage to your engine.

BATTERY SAVER ACTIVE

This message will display when the system detects that

the battery voltage is dropping beyond a reasonable

level. The battery saver system will start 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. If

you have an uplevel DIC, you can monitor the battery

voltage by pressing the gages button until BATTERY

displays.

the vehicle. See your GM dealer. See Engine Oil

acknowledging the message. The OIL LIFE screen

under the gages menu on the DIC must also be reset.

See “Oil Life” under DIC Operation and Displays on

page 3-47 and Engine Oil Life System on page 5-18.
