Getting into your car and driving off without stepping outside is a modern convenience that many love. The 2021 Jeep Wrangler offers remote start, making cold mornings or hot afternoons much easier. If you’re new to this feature or unsure how to use it, this guide will help you learn everything you need to know about remote starting your 2021 Jeep Wrangler. You’ll discover how it works, how to use it, what to expect, and some hidden tips that most owners miss.
Understanding Remote Start For Jeep Wrangler
Remote start allows you to start your vehicle’s engine from a distance. This means the cabin can be warmed up or cooled down before you enter. For the 2021 Jeep Wrangler, remote start is available with certain trims and packages, usually included with the Keyless Entry system.
How Does Remote Start Work?
Remote start uses your Jeep’s key fob to communicate with the engine. When you press the correct buttons, the system checks if the car is safe to start. If all conditions are met, the engine fires up, and climate controls activate based on your last settings.
Most owners don’t realize that remote start will not work if:
- The hood is open
- The car is not in Park
- The check engine light is on
These are common reasons why remote start sometimes fails.
Steps To Remote Start Your 2021 Jeep Wrangler
Starting your Jeep remotely is easy, but there are some details to watch for. Here’s a step-by-step guide:
- Locate your key fob. It should have a circular arrow button, often labeled with “x2.”
- Press the lock button once to secure the vehicle.
- Press and hold the remote start button (the circular arrow) for about two seconds.
- The Jeep’s lights will flash, and the engine will start.
- The climate system will turn on, using your last settings for heat or air conditioning.
Your Jeep will run for up to 15 minutes. If you don’t enter and drive, the engine will shut off automatically.
Important Notes
- Remote start works only within about 300 feet.
- If you press the remote start button again while the engine is running, the Jeep will turn off.
- You must unlock and enter the vehicle before driving. The key fob is required to keep the engine running.
