The Ultimate Guide to Remote Starting Your 2021 Subaru Crosstrek: A Step-by-Step Tutorial and Safety Tips

If you’re a Subaru Crosstrek owner or a potential buyer, you’d probably agree that being able to start your vehicle remotely would be a huge plus. After all, who doesn’t want to pre-heat or pre-cool their car before getting in, especially during extreme weather conditions? The good news is, the 2021 Subaru Crosstrek comes with remote start technology that makes this possible. In this article, we’ll guide you through the steps to remote start your car and provide you with some safety tips along the way.

Benefits of Remote Start Technology

Remote start technology lets you start your vehicle’s engine from a remote location. It typically involves fob or app-controlled ignition systems that are integrated into your car. With remote start, you can:

  • Warm up the engine before driving, which can help extend the engine’s lifespan.
  • Keep your car cool during hot weather or warm during cold weather, making your drive more comfortable.
  • Save time by eliminating the need to manually start your car before driving.
  • Boost safety by improving your visibility as you can clear ice, fog, or condensation from the windshield before driving.
  • Protect the environment by reducing carbon emissions from idling in the parking lot.

Requirements for Remote Starting the Vehicle

To use the remote start feature in your 2021 Subaru Crosstrek, you’ll need:

  • A compatible remote start fob or smartphone app that’s connected to your car’s system.
  • A valid subscription to the Subaru Starlink Safety and Security Plus package that includes Remote Engine Start with Climate Control.

Steps for Setting up Remote Start

Here are the steps to remote start your 2021 Subaru Crosstrek:

  1. Make sure your car is in park mode and the parking brake is on.
  2. Press the lock button on your remote start fob or smartphone app to lock your car.
  3. Press and hold the remote start button for at least three seconds, and your car will start automatically. Your car’s engine will run for up to 15 minutes or until you manually stop it by pressing the brake pedal.

Please note that for safety reasons, your car’s engine will shut down if you or anyone else tries to unlock your car with a key while the remote start is active. Also, if you don’t enter the car within 15 minutes, your car’s engine will turn off automatically.

Precautions and Safety Measures to Consider

Remote start technology can provide you with a lot of convenience and comfort, but we recommend that you follow these safety tips to avoid accidents or damage to your car:

  • Always park your car in a safe and secure location before using the remote start feature.
  • Never leave children or pets unattended in the car, even if you’re just remote starting it.
  • Be mindful of your car’s surroundings when remote starting it. Ensure there’s enough clearance around the car and that there are no obstacles nearby.
  • Don’t remote start your car in a closed garage or other enclosed spaces, as carbon monoxide emissions can be hazardous to your health.
