The engine temperature scale located on the right side of the PIDD screen changes to RED and the check engine temperature indicator located on the top left of the screen illuminates when the engine is overheating. Take action to cool the engine. See Engine-Cooling Actions. The indicator will flash when engine temperature reaches critical levels. Stop the engine immediately.

Please see your PIDD Owner’s Manual for more information.

Flashing Indicator

Flashing indicators indicate continued operation could result in serious engine damage. The engine management system will automatically reduce engine power and create a misfire condition. Stop the engine immediately. Allow the engine to cool down.

NOTE

If engine overheating seems to be caused by something other than poor cooling conditions, your dealer can perform this service.

Engine-Cooling Actions

If the engine is overheating, promptly take action to cool the engine.

Drive in loose snow.
View the coolant level. Do not open the pressure cap while the engine is hot.
Stop the engine and allow it to cool down.
Add coolant if the level is low. Do not add coolant while the engine is hot. Wait for the engine to cool before adding coolant.

NOTICE

If you must continue to operate while the indicator light is illuminated, drive slowly and stop the engine frequently to allow it to cool down.
