I believe when you remote start a Camaro for example, if the temperature is below a certain amount, the heated seats automatically come on, so the seats are preheated when you get in. Just wondering if this is true on the Sonic as well. Has anyone looked to see if its an option with the OnStar App when you remote start?
My Avalanche LTZ has heated seats and remote start. How it works is whatever you have the climate (HVAC) controls and heated seats set at when you leave the truck is what it reverts to when remote starting.
Once, during the summer, I didn't leave the AC on when leaving the truck. When I remote started it automatically selected AC and set the temp. Then again, my Avalanche has Automatic Climate Control, instead of standard HVAC controls.
I could be wrong, but considering the price of the Sonic, I wouldn't imagine the Sonic's heating/cooling system would be quite as sophisticated as that in the Avalanche LTZ. Then again, I could be wrong about that.
The Sonic Manual States:
The climate control will default to
the last used heating or cooling
mode. If the vehicle has heated
seats, they may come on during a
remote start.
When it is cold outside, the
heated seats can be turned on
automatically during a remote
vehicle start. The heated seats will
be canceled when the ignition is
turned on. Press the control to use
the heated seats after the vehicle is
started.
The heated seat indicator lights do
not turn on during a remote start.
The temperature performance of an
unoccupied seat may be reduced.
This is normal.
I have no clue what
"may come on during a remote start" means.
The manual doesn't state anything more regarding climate controls or heated seats relating to remote start... unless I missed that info.
