Disabling the auto start-stop feature on a 2019 Cherokee can be done through a simple button press or a more permanent software modification. Many drivers find the 2019 Jeep Cherokee auto start stop disable process essential for a smoother driving experience. This guide walks you through every method, from the quick fix to long-term solutions.
The auto start-stop system is designed to save fuel by shutting off the engine when you stop. But in real-world driving, it can be annoying, especially in traffic. You might want to turn it off for good, or at least for a single trip.
Let’s look at the easiest ways to handle this. We’ll cover the button, the settings menu, and even some aftermarket tricks. Each method has its own pros and cons, so pick what fits your needs.
Why Disable The Auto Start Stop System?
Before we jump into the how, let’s talk about the why. The system is meant to improve fuel economy, but it’s not always practical. In stop-and-go traffic, the constant restarting can feel jarring.
Some drivers worry about extra wear on the starter and battery. While modern components are built for this, the concern is valid. Others just prefer the engine running for a smoother ride.
Here are common reasons owners disable it:
- Annoying vibration when the engine restarts
- Delayed acceleration from a stop
- Concerns about battery and starter longevity
- Personal preference for engine always on
Whatever your reason, the 2019 Jeep Cherokee offers several ways to stop this behavior. Let’s start with the simplest method.
Using The Dashboard Button To Disable
The quickest way to turn off the system is with the dedicated button. This button is located near the gear shifter or on the center console. It has an icon that looks like an “A” with a circle around it.
Pressing this button once will disable the system for that ignition cycle. The next time you start the car, the system will be active again. This is a temporary fix, but it works instantly.
Here’s how to use it:
- Start your 2019 Jeep Cherokee.
- Locate the button with the “A” icon and an arrow.
- Press it once. You should see a light on the button or a message on the dash.
- The system is now off until you restart the engine.
This method is perfect for when you don’t want to mess with settings. It’s fast and requires no tools. But if you want a permanent solution, you’ll need to dig deeper.
2019 Jeep Cherokee Auto Start Stop Disable Via Settings Menu
Some trims of the 2019 Cherokee allow you to adjust this feature through the infotainment screen. This is a software-based method that might offer more control. Not all models have this option, so check your system.
To access the settings:
- Turn on the ignition but don’t start the engine.
- Press the “Settings” button on the touchscreen.
- Look for a menu labeled “Vehicle” or “Engine.”
- Find the “Auto Start Stop” option.
- Toggle it to “Off” or “Disable.”
This setting might not stick after a restart on all models. Some owners report it resets each time. If that happens, you’ll need a more permanent fix.
Check your owner’s manual for exact steps. The menu layout can vary between the base and Limited trims. If you don’t see the option, your vehicle might not support this method.
Permanent Disable With A Tazer Or Programmer
For a true permanent solution, aftermarket programmers are the way to go. Devices like the Tazer JL or Superchips Flashcal can disable the system at the ECU level. This is a popular choice for off-roaders and daily drivers alike.
These tools plug into the OBD-II port under the dashboard. They let you change multiple vehicle settings, including auto start-stop. The change is stored in the computer, so it stays off even after battery disconnects.
Here’s the general process:
- Purchase a compatible programmer like the Tazer JL.
- Locate the OBD-II port under the steering column.
- Plug in the device and follow the on-screen prompts.
- Select the “Auto Start Stop Disable” option.
- Confirm the change and unplug the device.
This method is not reversible without the programmer. But it gives you full control. Some devices also let you enable other features, like remote start or tire size adjustments.
Be aware that using a programmer might void your warranty. Check with your dealer before making changes. Also, ensure the device is compatible with the 2019 Cherokee specifically.
Using A Start Stop Eliminator Harness
Another permanent option is a plug-and-play harness. These harnesses trick the system into thinking the button was pressed. They are easy to install and don’t require programming skills.
Companies like Autostop Eliminator make harnesses for many Jeep models. The harness connects between the button and the vehicle’s wiring. Once installed, the system remembers your last setting.
Installation steps:
- Disconnect the battery negative terminal for safety.
- Remove the center console trim to access the button.
- Unplug the factory connector from the button.
- Plug the harness in between the button and the connector.
- Secure the harness with zip ties and reassemble the trim.
- Reconnect the battery and test the system.
This method is reversible and doesn’t alter the ECU. If you sell the car, you can remove it easily. It’s a good middle ground between the button and a programmer.
Make sure to buy a harness specifically for the 2019 Jeep Cherokee. Some universal ones might not fit correctly. Check customer reviews for compatibility.
Disabling Via Fuse Removal
Some owners try removing the fuse for the start-stop system. This is a risky method and not recommended. The fuse might also control other critical systems.
The start-stop system shares circuits with the transmission or engine control module. Pulling the wrong fuse can cause warning lights or drivability issues. You might even damage the computer.
If you’re determined to try, check your fuse box diagram. The fuse for start-stop is usually labeled “ESS” or “Auto Stop.” But again, this is a last resort.
Here’s why you should avoid it:
- Risk of electrical problems
- Possible check engine light
- May affect other features like hill start assist
- Not a clean solution
Stick to the button, settings, or a dedicated harness. Fuse removal is too unpredictable for most drivers.
What About The Battery?
The 2019 Cherokee uses an AGM battery designed for start-stop cycles. If you disable the system, the battery still works fine. But some drivers worry about charging.
The vehicle’s alternator adjusts charging based on load. Disabling start-stop won’t harm the battery. In fact, it might extend its life since it won’t cycle as often.
If you notice electrical issues after disabling, check the battery health. A weak battery can cause strange behavior. Replace it if it’s more than 3 years old.
Common Problems After Disabling
Most owners report no issues after disabling the system. But a few things can happen. The most common is a dashboard warning light.
The “ESS” light might stay on or flash. This is normal and indicates the system is off. It doesn’t mean there’s a malfunction.
Another rare issue is a dead battery if the car sits for weeks. The system is designed to save battery, so disabling it might drain it slightly faster. But this is only a concern if you don’t drive regularly.
If you use a programmer, some settings might reset after a dealer visit. You’ll need to reapply the change. Keep the programmer handy for such cases.
Step By Step: Using The Button Correctly
Let’s go through the button method in more detail. This is the most common way to disable the system for a trip. It’s simple but easy to forget.
Here’s a step-by-step:
- Start the engine and let it idle.
- Look for the button near the shifter. It has a circle with an “A” and an arrow.
- Press it firmly. You should hear a click.
- Check the dashboard. A light or message should confirm it’s off.
- Drive normally. The engine will not shut off at stops.
Remember, this only works for one ignition cycle. If you turn off the car and restart, the system is active again. You’ll need to press the button each time.
Some drivers get used to this routine. Others find it annoying and opt for a permanent fix. The choice is yours.
Software Update From Dealer
Some owners ask if a dealer can disable the system permanently. In most cases, dealers won’t do this. It’s a fuel economy feature, and they are not allowed to turn it off.
However, if there’s a software recall or update, the dealer might adjust the system. This is rare and usually only for fixing bugs. You can ask, but don’t expect a yes.
If you have a warranty concern, talk to the service manager. Some dealers are more flexible than others. But generally, you’re on your own for disabling it.
Cost Comparison Of Methods
Each method has a different cost. The button is free. The settings menu is also free. Aftermarket solutions cost money.
Here’s a rough breakdown:
- Button press: $0
- Settings menu: $0
- Start-stop harness: $80 to $150
- Tazer or programmer: $200 to $400
- Fuse removal: $0 but risky
Consider your budget and how much you want the feature gone. If you drive in traffic daily, a harness might be worth it. For occasional annoyance, just use the button.
Does Disabling Affect Fuel Economy?
Yes, disabling the system will slightly reduce fuel economy. The EPA estimates a 3-5% improvement with start-stop. In real-world driving, the difference is often less.
Most drivers don’t notice a significant change. The convenience of a smooth ride outweighs the tiny fuel savings. If you’re worried about gas mileage, keep the system on.
But for many, the trade-off is worth it. You can always enable it again if you want to save fuel on a long highway trip.
Tips For A Smoother Experience
If you decide to keep the system active, there are ways to make it less annoying. Light braking can prevent the engine from shutting off. The system only activates when you come to a complete stop.
Also, if you turn the steering wheel while stopped, the engine might restart. This is a safety feature. Use these tricks to control when the system engages.
But if you still hate it, disabling is the best option. You have plenty of choices, from simple to advanced.
