The start-stop system on the 2019 Jeep Compass aims to save fuel and reduce emissions by turning off the engine when your SUV is at a complete stop. While this feature is good for the environment and your wallet, many drivers find it annoying or inconvenient. For example, you may notice a delay when restarting, or feel a slight vibration. If you want to know how to disable start-stop on your 2019 Jeep Compass, this article will guide you through your options with practical tips and real-world advice.
Understanding Start-stop On The 2019 Jeep Compass
The start-stop system is standard on the 2019 Jeep Compass. When you come to a stop—such as at a red light—the engine automatically shuts off. The engine restarts as soon as you lift your foot off the brake pedal.
This system can help you save up to 5-10% on fuel in city driving. However, some owners worry about extra wear on the starter or battery. Others dislike the feeling of the engine stopping and starting, especially in heavy traffic.
Quick Ways To Disable Start-stop Temporarily
Jeep gives you a built-in way to turn off start-stop, but it only works for your current drive. Here’s what you can do:
Look for the A with a circle and the word “OFF” on your dashboard. It’s usually to the right of your steering wheel.
The system will display a message on your instrument cluster, confirming that start-stop is now off.
3. Remember, This Is Temporary
Each time you restart your car, start-stop will turn back on. You need to press the button every time.
If you want start-stop off for every trip, you’ll need a more permanent solution.
Permanent Ways To Disable Start-stop
Many drivers want a “set it and forget it” solution. There are a few options, but each has pros and cons.
1. Use A Start-stop Memory Module
A memory module is a small device that remembers your last start-stop setting. It plugs into your Jeep’s wiring under the dashboard.
- Pros: No need to press the button each time.
- Cons: Costs $40–$100; may affect your warranty.
- Example: SmartStopStart is a popular brand.
2. Disconnect The Battery Sensor
The Compass uses a battery sensor to help control start-stop. If you disconnect it, the system may stay off.
- Pros: Free and quick.
- Cons: May trigger warning lights or error messages; not recommended for most drivers.
3. Change The Hood Sensor Position
Start-stop won’t work if the car thinks the hood is open. Some people use a small magnet or adjust the hood latch sensor.
- Pros: Simple trick.
- Cons: Can trigger a “hood open” warning; may affect other systems.
4. Use An Obd-ii Programming Tool
Some tools can change your Jeep’s programming to disable start-stop.
- Pros: Professional and customizable.
- Cons: More expensive ($80–$200); can void warranty; not all tools work with Jeep Compass.
5. Ask Your Dealer
Some Jeep dealers may be able to help, especially if you have medical or safety reasons.
- Pros: Keeps your warranty.
- Cons: Not all dealers will do this.
Here’s a comparison to help you decide:
| Method | Cost | Warranty Risk | DIY Level |
|---|---|---|---|
| Start-Stop Button | $0 | None | Easy |
| Memory Module | $40–$100 | Possible | Moderate |
| Battery/Hood Sensor | $0 | High | Moderate |
| OBD-II Tool | $80–$200 | High | Advanced |
| Dealer | Varies | Low | Easy |
What Really Happens When You Disable Start-stop?
Disabling start-stop can make your drive smoother, especially in stop-and-go city traffic. Some people report that their battery and starter last longer, but there is not enough data to say this is always true.
However, you may lose out on some fuel savings. Over a year of city driving, you could pay $50–$100 more for gas without start-stop.
Here’s a look at how start-stop affects fuel use:
| City Driving | With Start-Stop | Without Start-Stop |
|---|---|---|
| Estimated MPG | 22–24 | 20–22 |
| Annual Fuel Cost (12,000 miles) | $1,400 | $1,500 |
Common Mistakes To Avoid
- Ignoring warranty issues: Making hardware or software changes could void your Jeep’s warranty. Always check with your dealer first.
- Choosing the wrong module: Not every memory module works with the 2019 Compass. Read reviews and check compatibility.
- Forgetting safety: Modifying sensors (battery or hood) can affect other car systems, such as security or charging.
- Not testing after changes: Always check that everything works after you make a change. Watch for warning lights or error codes.
Non-obvious Insights
- Start-stop may turn off automatically: If your battery is weak, the AC is on high, or it’s very hot/cold, the system will sometimes disable itself. You may not need to do anything.
- Software updates can change behavior: If you get a dealer software update, it may change how start-stop works or reset any changes you made.
When Should You Leave Start-stop On?
If you care most about fuel economy or do a lot of city driving, it’s best to leave start-stop active. Also, if your vehicle is under warranty or you plan to sell it soon, keeping things original may help keep resale value high.
