Starting your Jeep Grand Cherokee automatically can make life easier, especially on cold mornings or hot afternoons. The auto start feature lets you start your vehicle from a distance, so the cabin is comfortable before you get inside. Many owners are surprised by how simple it is to use, yet there are details to know for smooth operation. This guide explains how to auto start your Jeep Grand Cherokee, covers different methods, shares common mistakes, and compares key systems. If you’re new to remote start, you’ll find practical advice and answers to frequent questions.
Understanding Auto Start In Jeep Grand Cherokee
Jeep Grand Cherokee models from 2011 onwards often include a remote start system. This feature uses a signal from your key fob or smartphone to start the engine without turning the ignition manually. Remote start is useful for pre-heating or pre-cooling the interior, defrosting windows, and improving convenience.
Main Benefits
- Comfort: Start your car from inside your home or office.
- Safety: Defrost windows before driving.
- Convenience: No need to sit in a cold or hot car waiting for it to adjust.
Key Data
According to Jeep’s official data, over 70% of Grand Cherokees sold in the US since 2017 have a factory-installed remote start system. Aftermarket kits are also popular, but factory systems offer better integration.
How To Auto Start Jeep Grand Cherokee
Remote start operation varies by year and trim. Here’s a step-by-step process for most models:
Using The Key Fob
- Ensure conditions are met: All doors, hood, and trunk must be closed. The vehicle must be in park.
- Press the lock button: Hit the lock button on the key fob once.
- Activate remote start: Press the remote start button (circular arrow) twice within five seconds.
- Wait for confirmation: The exterior lights will flash, and the engine will start.
- Enter vehicle and drive: Unlock the car, enter, and press the brake pedal. Push the start button or turn the key to ON to fully activate.
Using Uconnect App
Some newer models (2018+) support remote start via the Uconnect app:
- Open the app on your smartphone.
- Log in with your credentials.
- Select Remote Start.
- Wait for confirmation.
Aftermarket Remote Start
If your Grand Cherokee does not have factory remote start, aftermarket kits are available. These require professional installation for reliable performance.
Comparison: Factory Vs Aftermarket Remote Start
To help you decide which system suits your needs, here’s a side-by-side comparison:
| Feature | Factory Remote Start | Aftermarket Remote Start |
|---|---|---|
| Integration | Fully integrated | May require extra steps |
| Warranty | Covered by Jeep warranty | May void vehicle warranty |
| Range | 300-500 ft | Up to 1,000 ft (depends on kit) |
| App support | Uconnect app | Some kits offer apps |
| Cost | Included or minor upgrade | $200-$600 plus installation |
Common Mistakes And Troubleshooting
Many users experience issues when using remote start for the first time. Here are mistakes to avoid:
- Doors not closed: The system won’t activate if any door, hood, or trunk is open.
- Wrong button sequence: Pressing the remote start button too slowly can fail the process.
- Low battery in key fob: Weak batteries can prevent the signal from reaching your vehicle.
- Security system active: If the alarm is triggered, remote start is disabled.
- Vehicle not in park: Always ensure the transmission is fully in park.
Troubleshooting Tips
- Change the key fob battery every 2 years for best results.
- If you see a flashing light but the engine doesn’t start, check for error messages on the dashboard.
- For app-based remote start, ensure your phone has an active internet connection.
Real-world Example
Sarah, a Jeep Grand Cherokee owner in Michigan, uses the remote start every winter. She locks her car, then presses the start button twice quickly. Her Jeep starts reliably, and by the time she reaches her car, the interior is warm and windows are clear.
She once forgot to close the trunk, and the remote start didn’t work—highlighting the importance of checking all doors.
Data: Remote Start Usage
A survey from AAA found that 41% of US drivers with remote start use the feature at least once a week during extreme weather. Among Jeep Grand Cherokee owners, the number is even higher during winter months.
| Season | % Owners Using Remote Start Weekly | Average Start Time (minutes) |
|---|---|---|
| Winter | 63% | 8 |
| Summer | 35% | 6 |
| Spring/Fall | 22% | 5 |
Extra Tips For Beginners
- Don’t leave valuables in your car while it’s running; remote start doesn’t unlock the doors.
- Engine runs for 15 minutes by default, then shuts off automatically.
- You can extend the running time by repeating the remote start process once.
Many beginners don’t realize that remote start only operates certain systems. For example, heated seats and steering wheel may not activate unless you set them before shutting off the car.
Another overlooked detail: If you use remote start in a closed garage, make sure there’s enough ventilation. Running the engine indoors can be dangerous due to carbon monoxide.
