If you own a Jeep Cherokee, you may have noticed the Stop Start system at work. This feature automatically shuts off your engine when you come to a stop, then restarts it when you release the brake. It’s designed to improve fuel efficiency and reduce emissions. However, many drivers find this system distracting or inconvenient, especially in heavy traffic. If you’re looking for ways to disable Stop Start on your Jeep Cherokee, this guide will give you clear options, practical steps, and insights you won’t find in basic manuals.
Understanding The Stop Start System
The Stop Start system was introduced to help meet strict environmental regulations. By turning off the engine at stops, it saves fuel and lowers CO2 emissions. Jeep claims this feature can improve fuel economy by up to 5%. However, real-world performance varies. For example, in city traffic, the system may activate dozens of times per day, which some drivers find annoying.
A key point: Stop Start is default ON every time you start your Cherokee. Many owners report that the system sometimes feels slow, and restarting can be rough, especially in older models or cold weather.
| Jeep Cherokee Model Year | Stop Start Feature | Fuel Economy Gain (%) |
|---|---|---|
| 2016-2018 | Standard | 2-3% |
| 2019-2021 | Enhanced | 3-5% |
| 2022-2024 | Advanced | 4-5% |
Why Disable Stop Start?
Some drivers prefer to disable Stop Start for reasons such as:
- Comfort: Engine restarts can be jerky.
- Battery life: Frequent starts may reduce battery lifespan.
- Starter wear: Increased use of starter motor can cause early wear.
- Personal preference: Some simply dislike the interruption.
It’s important to note that disabling Stop Start may affect your fuel economy slightly, but for many, the trade-off is worth it.
How To Disable Stop Start: Your Options
Disabling Stop Start is not as simple as flipping a permanent switch. Jeep designed the system to reset every time you restart the vehicle. Here are your main options:
Every Jeep Cherokee with Stop Start has a disable button near the gear shifter. Pressing this button turns off the system temporarily.
Steps:
- Start your Cherokee.
- Locate the Stop Start disable button (usually marked with an “A” and a circular arrow).
- Press the button. The dashboard indicator shows Stop Start is off.
Limitation: You must repeat this every time you restart the car. The system defaults to ON.
2. Use A Stop Start Override Device
There are aftermarket devices available that keep Stop Start disabled automatically.
How it works:
- The device plugs into your Cherokee’s OBD-II port or connects to the button wiring.
- Once installed, it remembers your preference and disables Stop Start each time.
Examples: Popular brands include SmartStopStart and Autostop Eliminator.
| Method | Installation Time | Cost (USD) | Permanent Solution |
|---|---|---|---|
| Manual Button | None | Free | No |
| Override Device | 10-20 min | $75-150 | Yes |
| Battery Disconnect | Varies | $0-20 | Temporary |
Tip: Choose a device specifically made for your Cherokee’s model year. Installation is usually simple, but some units require basic wiring skills.
3. Battery Disconnect Trick
Some owners disconnect or weaken the auxiliary battery that powers Stop Start. If the system detects low battery voltage, it won’t activate.
Steps:
- Locate the auxiliary battery under the passenger seat or hood.
- Disconnect or unplug it.
Warning: This method can cause error codes or affect other electrical systems. It is not recommended for long-term use.
4. Software Coding
Advanced users sometimes reprogram the Cherokee’s software to disable Stop Start.
How it works:
- Specialized tools or apps can change the system settings.
- This may void your warranty and risk damaging electronics.
Non-obvious insight: Jeep’s software updates may reverse coding, so this method is not always permanent.
Common Mistakes To Avoid
- Ignoring warranty risks: Some methods may void your warranty.
- Choosing the wrong device: Not all override devices fit every model year.
- Damaging electrical systems: Improper battery tricks can cause electrical faults.
- Assuming dealership will help: Dealers rarely disable Stop Start by request.
Pro tip: Always check compatibility and read customer reviews before buying devices.
Real-world Example
A 2020 Jeep Cherokee owner installed an Autostop Eliminator. Installation took 15 minutes and cost $120. The system remained off even after multiple restarts. The owner reported improved driving comfort and no warning lights. However, he noticed a slight decrease in city fuel economy, about 0.
5 mpg.
Data: Impact On Battery And Starter
Stop Start increases the number of starter activations. Research shows:
| Activation Type | Normal Driving (per year) | Stop Start Driving (per year) |
|---|---|---|
| Starter Motor | 5,000 | 20,000 |
| Battery Cycles | 300 | 1,200 |
This extra use may shorten the battery and starter’s lifespan by 10-20% over several years.
Final Thoughts
Disabling Stop Start in your Jeep Cherokee is possible, but it requires careful consideration. The manual button is easy but temporary. Override devices offer a permanent fix, but you must ensure compatibility. Battery tricks and software changes are risky. Always balance convenience with potential impacts on warranty, fuel economy, and vehicle electronics. If you’re unsure, consult a trusted mechanic before making changes.
