Disable Automatic Emergency Braking (AEB) in Jeep Grand Cherokee

Automatic Emergency Braking (AEB) is a crucial safety feature in modern vehicles that helps prevent or mitigate frontal collisions. In this article, we will explore how to access and customize the AEB settings in the Jeep Grand Cherokee. We will also delve into the various components and functionalities of the system, emphasizing the importance of responsible driving despite having advanced safety technologies.

What is AEB?

AEB stands for Automatic Emergency Braking. It is an advanced safety feature implemented in modern vehicles to help prevent or mitigate frontal collisions. AEB systems use sensors, such as radar, cameras, or a combination of both, to monitor the road ahead and detect potential obstacles or vehicles in the vehicle’s path.


When the AEB system detects an imminent collision, it provides warnings to the driver, typically through audible and visual alerts. If the driver fails to respond or take sufficient action, the AEB system can automatically apply the brakes to help avoid or reduce the severity of the collision.

The primary goal of AEB is to assist drivers in avoiding or minimizing the impact of frontal collisions, which are among the most common and dangerous types of accidents. By utilizing advanced sensor technology and intelligent algorithms, AEB systems can react faster than human drivers and help mitigate collisions, particularly in situations where a driver may be distracted, fatigued, or unable to react in time.

AEB systems typically have different modes or levels of functionality. Some systems provide warnings and precharge the brakes to increase braking effectiveness, while others are capable of full autonomous emergency braking, automatically applying the brakes to avoid or reduce the impact of a collision.

Accessing AEB Settings in the Jeep Grand Cherokee

To access the AEB settings in the Jeep Grand Cherokee, follow these steps:

  1. On the center screen of the Jeep Grand Cherokee, locate the “Vehicle” option on the bottom category bar.
  2. Tap on “Settings” in the top right corner of the screen.
  3. In the settings menu, select “Safety & Driving Assistance” from the left-side menu.
  4. Within the safety settings, find and open the “Automatic Emergency Braking” option.

Forward Collision Warning (FCW)

The Forward Collision Warning (FCW) system is a key component of AEB in the Jeep Grand Cherokee. It provides the driver with audible and visual warnings, as well as limited braking, to alert them to a potential frontal collision. The warnings and limited braking are designed to give the driver enough time to react, avoid, or mitigate the impending collision.

Within the AEB settings, you can control the FCW system in three modes:

“Off”: Selecting this mode will deactivate the FCW system entirely. An “Off” icon will be displayed on your Instrument Cluster Display, indicating that the FCW system is turned off.


“Only Warning”: This mode provides only an audible chime when a potential collision is detected. It does not apply any active braking.

“Warning + Active Braking”: This mode not only provides an audible chime but also applies some brake pressure when a potential collision is detected. It combines warning signals with active braking assistance to help mitigate the collision.

Pedestrian Emergency Braking (PEB)

The Pedestrian Emergency Braking (PEB) system is an additional feature within the AEB system of the Jeep Grand Cherokee. It is designed to detect potential collisions with pedestrians or cyclists and provide warnings and limited automatic braking.

Similar to the FCW settings, you can enable or disable the PEB system within the AEB settings menu. When PEB is turned off, an “Off” icon will be displayed on the Instrument Cluster Display.

Understanding AEB Functionality

The AEB system in the Jeep Grand Cherokee utilizes forward-looking sensors and the Electronic Brake Controller (EBC) to assess the probability of a frontal collision. When the system determines a potential collision, it provides progressive audible and visual warnings to alert the driver. If the driver fails to take action based on these warnings, the system can apply limited active braking to slow down the vehicle and mitigate the potential collision.

It’s important to note that the FCW system does not guarantee collision avoidance on its own, nor can it detect every type of potential collision. The ultimate responsibility for avoiding collisions lies with the driver, who should control the vehicle using braking and steering. The FCW system is designed to assist the driver by providing timely warnings and, if necessary, limited active braking support.

Safety Precautions and Limitations

While AEB systems like FCW and PEB offer significant safety benefits, it’s important to be aware of their limitations and exercise responsible driving:

  • AEB is not a substitute for attentive driving. Drivers must remain vigilant and actively control their vehicles to avoid collisions.
  • AEB systems may have difficulty detecting certain objects or situations, such as overhead objects, ground reflections, stationary objects far away, oncoming traffic, or vehicles traveling at similar or higher speeds.
  • The FCW system should be deactivated when driving off-road or in 4WD Low mode to prevent unnecessary warnings.
  • If the FCW system is disabled or experiences limited functionality, an indicator light will notify the driver. In such cases, it is recommended to have the system checked by an authorized dealer.
  • PEB is specifically designed for potential frontal collisions with pedestrians or cyclists, but it may not detect every type of pedestrian or cyclist or avoid every potential collision. The driver must remain attentive and ready to take evasive action.

Conclusion

Automatic Emergency Braking (AEB) is a vital safety feature in the Jeep Grand Cherokee, comprising the Forward Collision Warning (FCW) and Pedestrian Emergency Braking (PEB) systems. By accessing the vehicle’s settings, drivers can customize the AEB settings according to their preferences, including adjusting sensitivity and choosing between warning-only or active braking modes.


However, it’s crucial to remember that AEB systems are designed to assist drivers, not replace their responsibility to drive safely and attentively. Understanding the limitations of these systems and maintaining an active role in collision prevention will help ensure a safer driving experience for everyone on the road.
