We will be doing our first long road trip with our Model 3 LR AWD starting on Sunday. It may be fairly cool on the morning we leave (temperature around freezing is forecast overnight), so I'm seeking advice on how to keep a warm enough temperature in the car while minimizing impact on range. I've searched the forum, and the web, but haven't struck gold yet.
My current plan, subject to change based on advice, is:
Any advice is appreciated.
My current plan, subject to change based on advice, is:
- Preheat car interior before leaving, while the car is still plugged in. Select HVAC ON, and select a warm temperature.
- Before unplugging, select HVAC to Manual mode, with AC OFF, Air Recirculation OFF (to avoid drawing cold exterior air inside), and a low temperature (to avoid HVAC to heat the air)
- While driving, use seat heater as primary heat source. Only increase the HVAC temperature if max seat heat is not enough for comfort. Select Air Recirculation ON as required to avoid too much moisture inside.
- Keep fan at a relatively low value, unless higher setting is needed to defog windscreen or windows.
- Expect range to be 10% to 30% worse than in optimum temperatures.
Any advice is appreciated.
