Now, the weather is getting colder, especially at night. Now, remember the X5 with automatic climate control has a residual heat function.

When it is cold outside, the X5 can retain heat inside the cabin for about 20 minutes.

In the early model X5, the automatic climate control has a button labeled "REST". Later 2001-on X5s has a button labeled "MAX A/C"....

Let say it is in the 40F or colder outside and you park your X5 and have to run an errand (go in the supermarket or pick up at the cleaners, etc.) and you want to keep the X5 cabin warm.

1) Turn off X5
2) Press the "REST" or "MAX A/C" button and it will light up
3) Climate control will let warm air come through the floor vents for about 20 minutes

I used it today among visiting nursing homes (it was 41F going down to 37F tonight) and it worked well!
