That is not entirely true, when I remote start my truck, either cold or hot weather the truck's "Remote Start Comfort Systems — If Equipped" kicks in, you have to have this feature on your truck and make sure you go into your EVIC and enable it. Here is the description right out of the manual:
Remote Start Comfort Systems — If Equipped
When remote start is activated, the heated steering
wheel, and driver heated seat features will automatically
turn on in cold weather. In warm weather, the driver
vented seat feature will automatically turn on when the
remote start is activated. These features will stay on
through the duration of remote start or until the ignition
switch is turned to the ON/RUN position.
The Remote Start Comfort System can be activated and
deactivated through the Electronic Vehicle Information
Center (EVIC). For more information on Remote Start
Comfort System operation refer to “Electronic Vehicle
Information Center (EVIC)/Customer-Programmable
Features (System Setup)” in “Understanding Your Instrument
Hope this info helps.
