Climate Control Timer info
I went through the user manual and while I haven't yet verified it's operation, here's some key points that are stated:
-If you remotely turn on the climate control (just on or off, not using the timer), it can be operated for a maximum of 2 hours when the vehicle is plugged in, or 15 minutes if the vehicle is not plugged in.
-The timer function allows you to set the time that you want the vehicle to reach a certain temperature, or in other words what would be your departure time. For example, if you set it to 70 deg. on Monday at 6:00AM, it will figure out when it needs to turn the climate control system on (based on the current temp inside the vehicle) so the vehicle reaches 70 deg at 6:00AM. It will also shut the system off at 6:00AM because it's expecting you to depart at that time. It probably makes sense to set it for an extra 5-10 minutes beyond when you expect to leave in case you are running late so it won't shut off.
-On battery power specifically, the timer function won't run for more than 15 minutes.......so it may not be able to adequately cool down or warm up the car for the time you set.
Hope that helps
