Default Rear window Heater always on?
Every time I turn on my 2011 XK Coupe, the rear window heater comes on as well. It's no big deal to turn it off, but it's kind of annoying.
Has anyone else had this problem? Am I missing something obvious?
Regards,

What is the outside temperature when you see it on?

It is temperature sensitive and will turn on automatically at a predetermined temp. I forgot at what temp but believe it is in the OM.

Best part is that particular temperature the climate control does not display correct. I forget what it was...

I thought it also measures humidity. Not just temperature.

Heated screensThe front (
F
) and rear (
R
or
REAR
) screen heaters
may be switched on and
off in any mode,
including system off.
They will only operate
when the engine is running.
The front screen heater switches off
automatically after 6.5 minutes. The rear
screen and door mirror heaters switch off
automatically after 21 minutes.
The screen heaters can be manually deselected
using the buttons.
In cold ambient conditions, at the start of a
journey, the front and re
ar screen heaters will
switch on automatically for the timed period.
The rear heated screen will come on at
temperatures below -1°C (30°F) and the front
screen will come on below 5°C (41°F)

Thank you guys, especially Jagtoes. I really thought I had a problem, turned out the problem was me. Yes it has been cold in Minnesota lately.
RTFM!
