Remote engine start works by transmitting a signal from your smartphone app to your car’s ignition switch. This triggers the same processes that would engage if you started the car manually.Â
Traditional remote start systems, such as those installed after-market by third parties, communicate with the ignition over radio frequency. However, more modern systems, such as those that come standard in many Subaru models, communicate via your smartphone or mobile device’s Wi-Fi connection, sending signals from the MySubaru app to the vehicle’s built-in MySubaru Connected Services® Connected Services.Â
Depending on the type of system you have, engaging your remote start might automatically activate certain preset climate settings or, in the case of MySubaru Connected Services-connected systems, offer access to a variety of other options you can control.Â
On equipped Subaru models, you can use the MySubaru app to set your vehicle’s interior temperature, activate windshield wiper deicer, control your horn and lights, and more.Â
For security purposes, engaging remote start through the MySubaru app also automatically locks the doors and sets the alarm so that no one enters the vehicle without your permission. You can remotely lock and unlock the vehicle using the app or reach for the driver’s door with your key fob on-hand to automatically unlock it. However, the key fob must be inside the vehicle in order to drive the car.
