A/C OFF DUE TO HIGH ENGINE TEMP
This message displays when the engine coolant becomes hotter than the normal operating temperature.
To avoid added strain on a hot engine, the air conditioning compressor automatically turns off.
When the coolant temperature returns to normal, the air conditioning compressor turns back on. You can continue to drive the vehicle.
If this message continues to appear, have the system repaired by your dealer as soon as possible to avoid damage to the engine.
