Remote starting your 2015 Jeep Grand Cherokee can make your driving experience more comfortable. Imagine stepping into a warm cabin on a cold morning or a cool car during summer.
Many owners are unsure how to use this feature or what steps to follow. This guide will help you understand the process, avoid mistakes, and use your remote start confidently.
Even if you have used remote start on other cars, every system is a bit different, so it’s important to know how it works on your specific Jeep model.
Understanding Remote Start In The 2015 Jeep Grand Cherokee
The remote start system lets you start your engine from a distance. This is helpful for pre-conditioning your car’s interior, especially during extreme weather. Your Jeep uses a smart key fob with a dedicated button for remote start, which is often marked by a circular arrow. Knowing how this system works can prevent confusion and errors, such as trying to start the car when a door is open.
The remote start works only if:
- The car is locked
- The gear is in “Park”
- The hood is closed
- The key fob is within range (about 300 feet)
If any of these conditions are not met, remote start will not activate. This is a safety feature to prevent accidental starts and to make sure the car is secure.
For example, if the hood is not fully closed after maintenance, the system will not work.
Also, the system can sometimes be affected by interference from other electronic devices, such as garage door openers or strong Wi-Fi signals. Moving to a slightly different spot can help if you notice issues.
Steps To Remote Start Your 2015 Jeep Grand Cherokee
Follow these steps to use the remote start feature:
- Lock Your Vehicle
- Press the lock button on your key fob. Wait for the lights to flash once. This step is important because the system will not activate if any door is unlocked—even if you try to use the remote start button.
- Press Remote Start Button
- Locate the circular arrow button on your key fob.
- Press this button twice within five seconds. The lights will flash, and the engine will start. If you wait too long between presses, the system will not activate and you’ll need to try again from the first step.
- Wait for Confirmation
- The Jeep’s lights will flash again to confirm activation.
- The engine will run for 15 minutes before automatically shutting off if you do not enter. This helps save fuel and prevent unnecessary emissions.
- Enter Your Vehicle
- Unlock the car using the key fob.
- Insert your key fob (or press the start button, depending on your trim) to continue driving. If you do not do this, the car will shut off when you press the brake pedal.
- Turn Off Remote Start
- If you want to stop the engine before 15 minutes, press the remote start button again. This is useful if your plans change and you do not need to drive right away.
Remember, the climate control will turn on to your last used settings. For example, if you left the heater on high, the cabin will heat up quickly during remote start.
Quick Reference Table
Here’s a simple table to compare the main steps:
| Step | Action | Result |
|---|---|---|
| 1 | Lock car | Lights flash once |
| 2 | Press remote start twice | Engine starts, lights flash |
| 3 | Enter car | Ready to drive |
| 4 | Press remote start to turn off | Engine stops |
Common Problems And Solutions
Sometimes, remote start does not work. Here are frequent problems and fixes:
- Key fob battery weak: Replace the battery if range drops. Signs of a weak battery include needing to be closer to the car for the fob to work.
- Doors unlocked: Always lock before starting remotely. Even a slightly ajar door will prevent the system from working.
- Hood open: Make sure the hood is fully closed. Sensors detect if the hood is not latched, blocking remote start for safety.
- Check engine light on: Some issues block remote start. Inspect for warning lights. If your check engine light is on, the system may disable remote start until the problem is fixed, such as a sensor fault or emissions issue.
Other possible issues include interference from other electronics, or a damaged key fob. If your key fob has been dropped or exposed to water, it may need to be replaced.
Troubleshooting Data Table
This table shows common issues and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No response | Weak fob battery | Replace battery |
| Engine doesn’t start | Car not locked | Lock car |
| Remote start cancels | Open hood | Close hood |
| System disabled | Check engine light | Visit dealership |
Tips For Effective Remote Start Use
- Use remote start to warm up your car in winter or cool it in summer. Starting your car before you leave saves you time scraping ice or dealing with a hot interior.
- Do not leave the car unattended for long after starting. This reduces the risk of theft, even though the car cannot be driven without the key fob.
- Keep your key fob battery fresh for better range. Most batteries last about a year. If you notice reduced range or the need to press buttons harder, it is time to replace it.
- The system can be disabled from the settings menu if you don’t want to use it. This is helpful if you have children who might accidentally press buttons.
Two insights most people miss:
- If your Jeep is low on fuel, remote start may not work. This is a safety feature to prevent your car from running out of fuel while idling.
- If you start the car remotely but do not enter within 15 minutes, the engine shuts off automatically to save energy. You can repeat remote start once for another 15 minutes, but after that, you must start the car manually.
Another tip: If you live in a cold area, consider using remote start a few minutes before leaving for work, but avoid idling for too long, as it can waste fuel and is not good for the environment.
Comparing Trim Levels And Remote Start Features
Different trims of the 2015 Jeep Grand Cherokee may offer extra features with remote start, such as automatic climate control or heated seats. On higher trims, remote start can also activate seat warmers and steering wheel heaters, if equipped, making the cabin even more comfortable when you enter. Lower trims may only start the engine and basic climate controls.
| Trim Level | Remote Start | Extra Features |
|---|---|---|
| Laredo | Standard | Basic climate control |
| Limited | Standard | Heated seats |
| Overland | Standard | Ventilated seats, advanced climate |
| Summit | Standard | Premium interior, full climate |
Knowing your trim helps you get the most from remote start. For example, if you have the Overland or Summit, you can expect your Jeep to manage temperature and comfort more automatically during remote starts, which is a big advantage in extreme weather.
Safety And Legal Considerations
Remote start is safe if used correctly. Always park your Jeep away from enclosed spaces, like garages, to avoid carbon monoxide buildup.
Even a few minutes of running in a closed garage can be dangerous. Some states have laws about leaving a car running unattended.
Check your local rules to avoid fines.
If you have pets or small children, never leave them in a running car, even for a few minutes. The system is designed to prevent unauthorized driving, but safety should always come first.

Frequently Asked Questions
Can I Remote Start My Jeep From Inside My House?
Yes, if you are within about 300 feet and there are no barriers blocking the signal. Walls may reduce range.
If you live in a large building or have thick walls, you may need to step closer to a window or door.
Why Does Remote Start Fail Sometimes?
Common reasons are unlocked doors, open hood, low fuel, or a weak key fob battery. Fix these, and try again. Also, interference from other wireless devices or even a nearby cell tower can affect signal strength.
How Long Will The Engine Run After Remote Start?
It runs for 15 minutes. You can extend it once by repeating the remote start process, giving you a total of 30 minutes. After that, the system will require you to start the car manually.
Does Remote Start Work If My Jeep Is Low On Fuel?
No, the system prevents starting if the fuel level is too low to avoid running out unexpectedly. Always check your fuel level if remote start is not working for unknown reasons.
Can I Customize Remote Start Settings?
Yes. Some trims let you set climate control preferences or change run time in the settings menu.
Check your owner’s manual for details. You may also be able to set how the heated seats or steering wheel operate during remote start.
