It seems it takes a long time for my car to heat up when it's cold outside. My remote start only let's my car run for 15 minutes but even after that the car is slow to heat up. I leave the fan on high and the temp on 78 when I turn the car off the night before so it is starting up on these settings. I wish there was just a switch for the heater. I feel this car should get toasty warm after 15 minutes with it being a smaller car anyway. I'm rather disappointed about this.
