How To Disable Auto Start/Stop Jeep Grand Cherokee
Can you disable the auto start/stop on a Jeep Grand Cherokee? Yes, you can, and this guide will walk you through the most common methods to disable auto start/stop Jeep Grand Cherokee vehicles. Many drivers find the stop start system Jeep Grand Cherokee intrusive and prefer to turn off engine auto start stop. This system, designed for fuel efficiency and emissions reduction, often leads to driver annoyance due to its frequent engine cycling. Let’s explore how to bypass auto start stop Jeep and permanently disable engine auto start.
Why Drivers Seek to Disable Auto Start/Stop
The auto start/stop system in modern vehicles, including the Jeep Grand Cherokee, is a key feature in the push for better fuel economy and lower emissions. It automatically shuts off the engine when the vehicle comes to a stop, such as at traffic lights or in stop-and-go traffic, and restarts it when the driver lifts their foot off the brake or touches the accelerator. While beneficial in theory, many owners find it inconvenient.
Common complaints include:
- Annoyance and Disruption: The frequent stopping and starting can be jarring and distracting, especially for drivers who value a smooth, continuous driving experience.
- Wear and Tear Concerns: Some drivers worry about the long-term impact of constant engine restarts on the starter motor, battery, and other engine components.
- Reduced Comfort: The system can interrupt air conditioning or heating functions briefly when the engine shuts off, leading to minor discomfort in extreme temperatures.
- Performance Impact: In some cases, drivers report a slight delay when accelerating from a standstill if the engine is in the process of restarting.
These reasons drive many Jeep Grand Cherokee owners to seek a Jeep Grand Cherokee auto start stop solution that offers a more traditional driving experience.
Methods to Turn Off Engine Auto Start Stop
There are several approaches to consider when you want to turn off engine auto start stop on your Jeep Grand Cherokee. These range from simple, temporary fixes to more permanent modifications.
The Simple Button Approach
Most Jeep Grand Cherokee models equipped with the auto start/stop system have a dedicated button to temporarily disable it. This is usually located on the dashboard, often near the gear shifter or on the center console.
How to use the button:
- Locate the button: Look for a symbol that typically resembles a circle with an “A” inside and a line through it, or a similar icon indicating engine shut-off.
- Press the button: Each time you start your Jeep, the auto start/stop system is active by default. Pressing this button will disable it for the current driving cycle.
- Indicator light: A small indicator light on the button or dashboard will usually illuminate to confirm that the system is deactivated.
Limitations of the button method:
- Temporary: This setting is not permanent. The system will reactivate every time you turn off and restart your Jeep. You will need to press the button each time you want to disable it.
- Not a Permanent Solution: If you are looking for a way to permanently disable auto start stop, this method alone will not suffice.
Modifying Vehicle Settings (Where Available)
Some vehicle manufacturers offer an option within the infotainment system or vehicle settings to permanently disable the auto start/stop feature. It’s worth checking your Jeep Grand Cherokee’s owner’s manual or navigating through the infotainment system’s menus to see if such an option exists for your specific model year and trim level.
How to check for settings:
- Access Vehicle Settings: Navigate through your Jeep Grand Cherokee’s infotainment screen. Look for sections labeled “Vehicle,” “Settings,” “Driving Modes,” or similar.
- Locate Auto Start/Stop Option: Within these menus, search for an option related to “Auto Start/Stop,” “Engine Idle Stop,” or “Eco Mode” that might be linked to the system.
- Disable if Available: If you find an option to disable it permanently, select it.
Caveats:
- Availability Varies: This feature is not universally available across all Jeep Grand Cherokee models and model years. Many vehicles require aftermarket solutions for permanent disabling.
- May Not Be Truly Permanent: Even if you find such a setting, some systems might still default back to “on” after certain software updates or battery disconnects.
Aftermarket Solutions for Permanent Disabling
For those seeking a permanent start stop disable, aftermarket solutions are often the most effective approach. These methods involve modifying how the system is controlled, ensuring it stays off without requiring manual intervention each time.
OBD-II Programmers and Modules
One of the most popular and relatively straightforward ways to bypass auto start stop Jeep is by using an OBD-II (On-Board Diagnostics) programmer or a dedicated module. These devices plug into your Jeep’s OBD-II port, typically located under the dashboard.
How OBD-II programmers work:
- Reprogramming: Some programmers allow you to access and modify vehicle parameters, including disabling the auto start/stop system.
- Modules: Other devices are designed as plug-and-play modules that intercept the signals controlling the auto start/stop system and effectively “trick” the vehicle into believing the feature is always off.
Popular brands and considerations:
Many companies offer these types of modules. When choosing one, consider:
- Compatibility: Ensure the module is specifically designed for your Jeep Grand Cherokee’s make, model, and year.
- Ease of Installation: Most are designed for simple plug-and-play installation.
- Reversibility: It’s ideal to choose a solution that can be easily removed if you ever want to re-enable the system.
- Warranty: Check if using such a module will void your vehicle’s warranty. Some manufacturers may have policies against modifications.
Table: Popular Aftermarket Module Brands (Examples – Research specific compatibility)
| Brand Example | Type of Solution | Notes |
|---|---|---|
| Brand A Solutions | OBD-II Module | Often plug-and-play, designed for specific models. |
| Brand B Performance | Programmer | May offer other tuning options alongside disabling. |
| Brand C Auto | Bypass Module | Focuses solely on disabling start/stop systems. |
Important Note: Always purchase from reputable vendors and read reviews carefully.
Battery Saver Disable Modules
Some aftermarket solutions specifically target the Jeep Grand Cherokee battery saver disable aspect of the auto start/stop system. These modules work by preventing the system from detecting that the battery is sufficiently charged for the auto start/stop function to engage. Effectively, it keeps the system from thinking it needs to shut off the engine to save battery power.
How these modules operate:
- Interference: They are typically installed inline with the battery or related sensors.
- Simulated State: They trick the vehicle’s computer into thinking the battery is not in a state where auto start/stop should engage.
Installation:
- DIY Friendly: Many of these modules are designed for straightforward installation, often requiring minimal tools and electrical knowledge.
- Wiring: Installation might involve connecting to specific wires or a sensor. Always follow the manufacturer’s detailed instructions.
Manual Mode Activation (For some models)
Some Jeep Grand Cherokee models might have a “manual mode” or a specific transmission setting that can influence the auto start/stop behavior. For example, engaging the manual shift mode (using paddle shifters or the gear selector) might sometimes prevent the auto start/stop from activating.
How to test this:
- Engage Manual Mode: Shift your Jeep into its manual mode or select a lower gear range if available.
- Test at a Stop: Come to a complete stop and observe if the engine continues to run.
Limitations:
- Not Universal: This functionality is highly dependent on the specific model year and transmission configuration.
- Requires Manual Input: You still need to actively engage manual mode, which isn’t a passive or permanent solution.
Impact of Disabling Auto Start/Stop
While disabling the auto start/stop system offers the convenience many drivers desire, it’s important to consider the potential implications.
Fuel Economy
- Reduced Fuel Efficiency: The primary purpose of the auto start/stop system is to save fuel. By disabling it, you will likely see a decrease in your overall fuel economy, especially in city driving with frequent stops. The exact amount will vary depending on your driving habits and traffic conditions.
Emissions
- Increased Emissions: Less fuel burned generally means fewer emissions. However, the auto start/stop system is designed to reduce emissions during idling. Disabling it means the engine will be running at idle more often, potentially leading to a slight increase in emissions.
Vehicle Components
- Starter Motor and Battery: While modern systems are designed for millions of starts, consistently disabling the system means the starter motor and battery will experience less strain from frequent cycling. Some argue this could prolong the life of these components, while others contend the systems are robust enough to handle the intended use.
- Other Systems: Ensure that disabling the system doesn’t inadvertently affect other vehicle functions, like air conditioning performance or charging systems. Reputable aftermarket solutions are designed to avoid these issues.
Warranty Concerns
- Potential Voiding: As mentioned, using aftermarket electronic modules or reprogramming tools can potentially void your vehicle’s powertrain warranty. It’s crucial to check your warranty documentation and the policies of your dealership. Some solutions might be more discreet and less likely to be detected than others.
