Remote Start Key Fob

The 2021 Hyundai Santa Fe comes equipped with a remote start feature on its key fob, allowing owners to start their vehicle from a distance. This convenient function is especially useful in extreme weather conditions, enabling you to warm up or cool down your car before entering.

To use the remote start feature on your 2021 Hyundai Santa Fe key fob, follow these steps:

1. Ensure you are within range of your vehicle (typically about 30-50 feet).

2. Press the lock button on your key fob to secure the vehicle.

3. Press and hold the remote start button (usually marked with a circular arrow) for about 2-3 seconds.

4. The vehicle's exterior lights will flash, and the engine will start.
