If you drive a 2018 Jeep Compass, you may have noticed the engine shuts off automatically when you stop at red lights or in traffic. This feature, called Auto Stop-Start, is designed to save fuel and reduce emissions. But for many drivers, it can feel annoying or even disruptive, especially if you prefer smooth acceleration or live in areas with frequent stops. If you’ve wondered how to turn off Auto Stop on your 2018 Jeep Compass, this guide will show you everything you need to know.
Why Does Auto Stop-start Exist?
The main reason for Auto Stop-Start is to make cars more fuel-efficient. By shutting off the engine when your vehicle is stopped, it helps reduce fuel consumption and emissions. According to the Environmental Protection Agency (EPA), using stop-start technology can improve fuel economy by up to 5% in city driving.
But while the feature is smart, some people find it frustrating. The engine restarts can feel rough, and you might worry about extra wear on the starter.
Also, the AC might not cool as well when the engine is off.
How The Auto Stop-start System Works
The Auto Stop-Start system is automatic. When you come to a full stop with your foot on the brake, the engine turns off. Once you lift your foot, the engine starts again instantly.
But the system only works if certain conditions are met:
- The battery is charged
- The engine is warm enough
- The outside temperature is not too hot or cold
- The driver’s seat belt is fastened
- The hood is closed
If any of these aren’t true, the engine may stay on.
Is It Possible To Turn Off Auto Stop On The 2018 Jeep Compass?
The quick answer: Jeep did not include a permanent “off” switch for Auto Stop on the 2018 Compass. Each time you start the car, the system is active by default. However, there are ways to temporarily or permanently disable it.
How To Turn Off Auto Stop (factory Method)
Your Jeep Compass has an Auto Stop-Start OFF button located near the gear shifter (sometimes labeled “A OFF”). Pressing this button will disable the system, but only for your current drive. The next time you turn the car off and on, Auto Stop-Start will reactivate.
Steps:
- Start your Jeep Compass.
- Locate the A OFF button (it may have an “A” with a circular arrow).
- Press the button. You’ll see a light on the dashboard indicating Auto Stop-Start is off.
- Drive as usual. The engine will no longer turn off at stops during this trip.
Note: This does not permanently turn off the feature.
Common Methods For Disabling Auto Stop Permanently
Many drivers want a permanent solution. Here are the most common options:
1. Use A Bypass Device
Aftermarket companies sell Auto Stop-Start eliminators that plug into your car’s wiring. These devices “remember” your preference, so Auto Stop stays off—even after you restart the car.
Pros:
- Easy to install (often plug-and-play)
- No permanent changes to your Jeep
Cons:
- May affect warranty
- Not officially approved by Jeep
2. Change Driving Habits
If you don’t want to add hardware, you can “trick” the system:
- Shift into Park at stops (the engine stays on)
- Release the brake for a moment to restart the engine
- Use heavy AC or high heat, which sometimes disables Auto Stop
But these are not always practical and can distract you from driving.
3. Dealer Reprogramming
Some Jeep dealers may agree to reprogram your Compass to disable Auto Stop-Start. However, this is rare and may not be allowed, as it can affect emissions compliance.
Key Differences: Factory Vs. Aftermarket Solutions
Here’s a quick comparison to help you choose:
| Method | Permanent? | Warranty Impact | Cost |
|---|---|---|---|
| Factory Button | No | None | Free |
| Bypass Device | Yes | Possible | $50–$120 |
| Dealer Reprogram | Yes | Possible | $100–$200 |
Important Considerations Before Disabling Auto Stop
Turning off Auto Stop-Start means you might use more fuel, and your Jeep will produce more emissions. In some places, disabling it could even affect your car’s compliance with local laws.
Also, if you use an aftermarket device, check your warranty. Some Jeep dealers may refuse repairs if they find a non-factory modification.
Real-world Example: Owner Experiences
Many owners on Jeep forums report that bypass devices solve their annoyance with Auto Stop. For example, one 2018 Compass owner said, “With the eliminator installed, I never have to think about the button again. My engine stays on at every stop.
”
But a few people noticed that their fuel economy dropped by about 1–2 miles per gallon after disabling the feature. This is important if you drive a lot in the city.
Pros And Cons Of Disabling Auto Stop
| Pros | Cons |
|---|---|
| No engine restarts at stops | Lower fuel efficiency |
| Smoother driving feel | More emissions |
| Less starter wear (possibly) | Potential warranty issues |
Two Common Myths About Auto Stop
- It damages your starter quickly. Starters in modern cars like the Jeep Compass are designed for frequent use, so extra wear is minimal.
- It cannot be turned off at all. You can disable it for each drive, and with a device, you can make it permanent.
Extra Tips For Jeep Compass Owners
- If you use a bypass device, keep the original wiring handy in case you need dealer service.
- Check for new Jeep Compass software updates. Sometimes, the Auto Stop-Start system gets updates that may change how it works or add new options.
- If you drive in extreme weather, Auto Stop may not activate anyway, as the system protects the engine and battery.
