This is the first real cold spell we've had and I noticed something I don't think is right. After shutting the car off after the trip home from work the heat blower comes on. The car is completely shut down, engine off and all of a sudden the heat starts blowing. Is this normal or do I need to make a visit to the service department?

I try to avoid bringing the car in unless it's necessary. Vehicle is under warentee but if it ain't broke don't fix it right?

Thanks in advance for any suggestions.

That is the function of the EC Rest button. It keeps circulating heated air within the cabin to keep it warm.

I thought it might be. I remember reading about this when I first got the car but didn't realize it would come on by itself. I think the REST button was off when the fan came on before. I'll have to keep an eye on it but thanks for the reply. I hope you're right. Thanks

You mean the heater blower comes on? No it should not come on without user action.

I thought the REST feature cannot be on from a previous activation, perhaps an issue with the blower regulator (I once had a blower regulator failure and it kept the blower on at full speed)?

Correct, I just tested it in my car. My bad.

I think you guys were right.

Hasn't happened since, although its warmed up a bit.

Not sure now if the REST light was on or off so I'm not going to worry about it.

I appreciate the posts. Thanks again for your help.
