The Jeep Grand Cherokee stands as one of the most popular SUVs in America, known for its rugged build and advanced features. One of the most convenient options available is the auto start (also called remote start) function. Auto start can warm up or cool down your vehicle before you enter, making daily life smoother, especially during extreme weather. But not every owner uses this feature to its full potential—or even knows how to set it up. Here’s a clear, step-by-step guide on how to auto start a Jeep Grand Cherokee, with practical advice, tips, and answers to common questions.
Understanding The Auto Start Feature
Auto start, or remote start, allows you to start your Jeep Grand Cherokee’s engine from a distance. The climate control system can also activate, warming up or cooling down your cabin. This feature is factory-installed in many Grand Cherokees from 2011 onwards, but the exact process can vary by model year and trim.
Key Benefits
- Comfort: Pre-heat or pre-cool your interior before driving.
- Convenience: Start your Jeep while inside your home or office.
- Safety: Defrost windows in winter; avoid entering a hot car in summer.
What You Need
- A Jeep Grand Cherokee equipped with factory remote start (most models from 2011+).
- The original key fob with a remote start button (circular arrow icon).
- A Jeep with an automatic transmission (manual transmissions typically do not support remote start).
If your vehicle doesn’t have remote start, aftermarket systems are available, but professional installation is recommended.
How To Auto Start Your Jeep Grand Cherokee
Activating remote start is simple, but some steps may differ slightly depending on your year and model. Here’s a general guide:
- Lock the doors using your key fob (press the lock button once).
- Press the remote start button (the button with a circular arrow) twice within five seconds.
- The turn signals will flash and the engine will start. The parking lights may stay on while the engine is running.
Example Scenario
Imagine it’s a cold morning. From inside your house, you press lock, then the remote start button twice.
Your Grand Cherokee’s engine starts, and the heater begins to warm the interior even before you step outside.
Important Details
- The vehicle will run for 15 minutes (default time) before shutting off if you don’t enter and drive.
- If you do not unlock and enter the vehicle within two cycles (about 30 minutes), you must manually restart.
- You must have enough fuel—if the tank is low, remote start won’t activate.
- The hood, doors, and liftgate must be closed, and the transmission in “Park.”
Auto Start By Model Year: Key Differences
The exact steps and features vary slightly by year. The table below summarizes key differences for popular Jeep Grand Cherokee model years:
| Model Year | Remote Start Standard? | Key Fob Button | Max Run Time |
|---|---|---|---|
| 2011-2013 | Optional/Some trims | Circular arrow (hold 2x) | 10 min x2 |
| 2014-2019 | Standard on most trims | Circular arrow (press 2x) | 15 min x2 |
| 2020+ | Standard | Circular arrow (press 2x) | 15 min x2 |
Troubleshooting Common Problems
Sometimes, auto start doesn’t work as expected. Here are common problems and how to fix them:
1. No Response From The Vehicle
- Possible causes: Hood/doors open, low fuel, check engine light on, or the vehicle is not in “Park.”
- Solution: Ensure all doors and the hood are closed, transmission is in “Park,” and the tank has enough fuel.
2. Engine Starts But Immediately Shuts Off
- Possible causes: Key fob battery is weak or there’s an issue with the immobilizer.
- Solution: Replace the key fob battery. If the problem continues, visit a Jeep dealer.
3. Signal Range Is Short
- Possible causes: Battery low, interference from buildings or electronics.
- Solution: Stand closer to the vehicle or replace the key fob battery.
4. Climate Control Doesn’t Activate
- Possible causes: Settings not saved, or the system is off.
- Solution: Set your preferred climate control settings while the engine is running. The system will remember for next time.
Using The Uconnect App For Remote Start
Newer Jeep Grand Cherokees (especially 2018 and later) often support remote start through the Uconnect app on your smartphone. This method works almost anywhere you have a cell signal.
How To Set Up Uconnect Remote Start
- Download the Uconnect app from the App Store or Google Play.
- Create an account and connect your vehicle using the VIN (vehicle identification number).
- Tap the “Remote Start” icon in the app.
- Wait for confirmation—your Jeep will start, and you’ll see a notification.
Benefits Of Using The App
- Start your Jeep even if you’re far from the vehicle.
- Control other features like lock/unlock, horn, and lights.
- Get vehicle status updates.
Real-world Example
You’re at work and remember a snowstorm is coming. Open the Uconnect app, tap “Remote Start,” and your Grand Cherokee begins warming up, saving you time and effort.
Safety And Legal Considerations
Remote start is legal in most US states, but some areas have rules about idling vehicles. For example, some cities limit the time a car can run unattended. Always check your local laws to avoid fines.
Safety Tips
- Never use auto start in a closed garage—the engine produces carbon monoxide, which is deadly in enclosed spaces.
- Always make sure the car is in “Park” and on level ground.
- Do not leave children or pets in the vehicle, even if it’s running.
Aftermarket Remote Start Options
If your Jeep Grand Cherokee does not have factory remote start, you can add an aftermarket system. These vary in price, features, and installation complexity. Professional installation is strongly recommended to avoid electrical issues or warranty problems.
Factory Vs. Aftermarket: Quick Comparison
| Feature | Factory Remote Start | Aftermarket System |
|---|---|---|
| Warranty | Fully covered | May void warranty if not installed by dealer |
| Integration | Seamless with Jeep electronics | Some features may not integrate fully |
| Cost | Higher initial price | Range from $150–$600 plus install |
| Features | Climate, lock/unlock, security | Varies; some include smartphone control |
Two non-obvious tips for buyers:
- If you lease your Jeep, always choose factory remote start to avoid lease penalties.
- Always verify that the aftermarket system is compatible with your model year and does not require cutting factory wiring, which can cause problems later.
Practical Tips For Everyday Use
To get the most from auto start, keep these suggestions in mind:
- Set climate preferences before leaving the vehicle. The system will use your last settings next time you remote start.
- Replace key fob batteries every 1-2 years. Weak batteries reduce range and reliability.
- Don’t use remote start in a closed garage. Always start in a well-ventilated area.
- Check for software updates if using Uconnect. Updates can add features and improve reliability.
- Carry a spare key fob if you rely on remote start, especially in cold weather.
Common Mistakes To Avoid
- Trying to remote start with the hood or doors open—the system will not activate.
- Forgetting to unlock the door before entering; once inside, press the brake and push the start button to drive.
- Using the wrong key fob sequence (press the remote start button twice, not just once).
- Attempting to use remote start with a manual transmission—most Jeep Grand Cherokees do not support this for safety reasons.
- Ignoring warning lights on the dashboard, which can disable remote start.
